Notes to Condensed Consolidated Financial Statements

(unaudited)

1. BASIS OF PRESENTATION

The accompanying unaudited Condensed Consolidated Financial Statements of Southwest Airlines Co. and its subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles ("GAAP") in the United States for complete financial statements. The unaudited Condensed Consolidated Financial Statements for the interim periods ended June 30, 2013 and 2012 include all adjustments which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods. This includes all normal and recurring adjustments and elimination of significant intercompany transactions. Financial results for the Company and airlines in general can be seasonal in nature. In many years, the Company's revenues, as well as its operating income and net income, have been better in its second and third fiscal quarters than in its first and fourth fiscal quarters. Air travel is also significantly impacted by general economic conditions, the amount of disposable income available to consumers, unemployment levels, and corporate travel budgets. These and other factors, such as the price of jet fuel in some periods, the nature of the Company's fuel hedging program, the periodic volatility of commodities used by the Company for hedging jet fuel, and the requirements related to hedge accounting, have created, and may continue to create, significant volatility in the Company's financial results. See Note 5 for further information on fuel and the Company's hedging program. Operating results for the three and six months ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ended December 31, 2013 . For further information, refer to the Consolidated Financial Statements and footnotes thereto included in the Southwest Airlines Co. Annual Report on Form 10-K for the year ended December 31, 2012 .

Certain prior period amounts have been reclassified to conform to the current presentation. In the unaudited Condensed Consolidated Statement of Comprehensive Income for the three and six months ended June 30, 2012 , the Company has reclassified $ 9 million and $17 million , respectively, from Other revenues to Passenger revenues associated with its sale of frequent flyer benefits from its co-branded Chase® Visa credit card.

2. AIRTRAN ACQUISITION AND RELATED MATTERS

AirTran Holdings, Inc.

On May 2, 2011 (the “acquisition date”), the Company acquired all of the outstanding equity of AirTran Holdings, Inc. (“AirTran Holdings”), the former parent company of AirTran Airways, Inc. (“AirTran Airways”), in exchange for Southwest Airlines Co. common stock and cash. Throughout this Form 10-Q, the Company makes reference to AirTran, which is meant to be inclusive of the following: (i) for periods prior to the acquisition date, AirTran Holdings and its subsidiaries, including, among others, AirTran Airways; and (ii) for periods on and after the acquisition date, AirTran Holdings, LLC, the successor to AirTran Holdings, and its subsidiaries, including among others, AirTran Airways.

In July 2012, the Company announced that AirTran's Boeing 717-200 aircraft will be transitioned out of the Company’s fleet over a three-year period beginning in August 2013. See Note 8 for further information.

Expenses related to the AirTran acquisition

The Company is expected to continue to incur substantial Acquisition and integration expenses in connection with the AirTran acquisition, including the necessary costs associated with integrating the operations of the two companies. While the Company has assumed that a certain level of expenses will be incurred, there are many factors that could affect the total amount or the timing of these expenses, and many of the expenses that will be incurred are, by their nature, difficult to estimate. These expenses could, particularly in the near term, exceed the financial benefits that the Company expects to achieve from the AirTran acquisition and could continue to result in the Company taking significant charges against earnings during the integration process. The Company incurred acquisition and integration-related costs for the three and six months ended June 30, 2013 of $ 26 million and $ 39 million , respectively, primarily consisting of costs associated with Employee training, technology integration projects, and facility integration expenses. The Company incurred acquisition and integration-related costs for the three and six months ended June 30, 2012 of $ 11

Southwest Airlines Co.

(unaudited)

million and $ 24 million , respectively, primarily consisting of costs associated with consulting, flight crew training, and seniority integration. In the Company’s unaudited Condensed Consolidated Statement of Comprehensive Income, these costs are classified as Acquisition and integration expenses.

3. REVOLVING CREDIT FACILITY

On April 2, 2013, the Company entered into a new $ 1 billion unsecured revolving credit facility expiring in April 2018 , and terminated its previous facility, which would have expired in April 2016. Other than an increased borrowing capacity, this new facility is substantially the same as the previous facility. Interest on the facility is based on the Company's credit ratings at the time of borrowing. At the Company's current ratings, the interest cost would be LIBOR plus a spread of 150 basis points . The new facility also contains the same financial covenant as the previous facility, requiring a minimum coverage ratio of adjusted pre-tax income to fixed obligations, as defined. As of June 30, 2013 , the Company was in compliance with this covenant and there were no amounts outstanding under the revolving credit facility.

4. NET INCOME PER SHARE

The following table sets forth the computation of basic and diluted net income per share (in millions except per share amounts):

5. FINANCIAL DERIVATIVE INSTRUMENTS

Fuel contracts

Airline operators are inherently dependent upon energy to operate and, therefore, are impacted by changes in jet fuel prices. Furthermore, jet fuel and oil typically represent one of the largest operating expenses for airlines. The Company endeavors to acquire jet fuel at the lowest possible cost and to reduce volatility in operating expenses through its fuel hedging program. Although the Company may periodically enter into jet fuel derivatives for short-term timeframes,

because jet fuel is not widely traded on an organized futures exchange, there are limited opportunities to hedge directly in jet fuel for time horizons longer than approximately 6 to 12 months into the future. However, the Company has found that financial derivative instruments in other commodities, such as West Texas Intermediate (“WTI”) crude oil, Brent crude oil, and refined products, such as heating oil and unleaded gasoline, can be useful in decreasing its exposure to jet fuel price volatility. The Company does not purchase or hold any financial derivative instruments for trading or speculative purposes.

The Company has used financial derivative instruments for both short-term and long-term time frames and primarily uses a mixture of purchased call options, collar structures (which include both a purchased call option and a sold put option), call spreads (which include a purchased call option and a sold call option), and fixed price swap agreements in its portfolio.

The Company evaluates its derivatives volumes strictly from an “economic” standpoint and thus does not consider whether the derivatives have qualified or will qualify for hedge accounting. The Company defines its “economic” hedge as the net volume of fuel derivative contracts held, including the impact of positions that have been offset through sold positions, regardless of whether those contracts qualify for hedge accounting. The level at which the Company is economically hedged for a particular period is also dependent on current market prices for that period, as well as the types of derivative instruments held and the strike prices of those instruments.

For the three months ended June 30, 2013 , the Company had fuel derivative instruments in place for 94 percent of its fuel consumption. As of June 30, 2013 , the Company had fuel derivative instruments in place to provide coverage for approximately 93 percent of its remaining 2013 estimated fuel consumption. The following table provides information about the Company’s volume of fuel hedging for the years 2013 through 2017 on an “economic” basis considering current market prices:



	Fuel hedged as of
	June 30, 2013	Derivative underlying commodity type as of
Period (by year)	(gallons in millions) (a)	June 30, 2013
Remainder of 2013	843	Brent crude oil and Gulf Coast jet fuel
2014	1,444	WTI crude and Brent crude oil
2015	790	WTI crude and Brent crude oil
2016	977	Brent crude oil
2017	933	WTI crude and Brent crude oil

(a) The Company determines gallons hedged based on market prices and forward curves as of June 30, 2013 . Due to the types of derivatives utilized by the Company, these volumes may vary significantly as market prices fluctuate.

Upon proper qualification, the Company accounts for its fuel derivative instruments as cash flow hedges. Generally, utilizing hedge accounting, all periodic changes in fair value of the derivatives designated as hedges that are considered to be effective are recorded in Accumulated other comprehensive income (loss) ("AOCI") until the underlying jet fuel is consumed. See Note 6 . To the extent that the periodic changes in the fair value of the derivatives are ineffective, the ineffective portion is recorded to Other (gains) losses, net, in the unaudited Condensed Consolidated Statement of Comprehensive Income. Likewise, if a hedge ceases to qualify for hedge accounting, any change in the fair value of derivative instruments since the last reporting period is recorded to Other (gains) losses, net, in the unaudited Condensed Consolidated Statement of Comprehensive Income in the period of the change; however, any amounts previously recorded to AOCI would remain there until such time as the original forecasted transaction occurs, at which time these amounts would be reclassified to Fuel and oil expense. In a situation where it becomes probable that a fuel hedged forecasted transaction will not occur, any gains and/or losses that have been recorded to AOCI would be required to be immediately reclassified into earnings. The Company did not have any such situations occur during 2012 or during the six months ended June 30, 2013 .

All cash flows associated with purchasing and selling fuel derivatives are classified as Other operating cash flows in the unaudited Condensed Consolidated Statement of Cash Flows. The following table presents the location of all assets and liabilities associated with the Company’s derivative instruments within the unaudited Condensed Consolidated Balance Sheet:



		Asset derivatives				Liability derivatives

All of the Company's fuel derivative instruments and interest rate swaps are subject to agreements that follow the netting guidance in the applicable accounting for derivatives and hedging. The types of derivative instruments the Company has determined are subject to netting requirements in the accompanying unaudited Condensed Consolidated Balance Sheet are those in which the Company pays or receives cash for transactions with the same counterparty that settle on the same day and in the same currency via one net payment or receipt. For cash collateral held by the Company or provided to counterparties, the Company nets such amounts against the fair value of the Company's derivative portfolio by each counterparty. The Company has elected to utilize netting for both its fuel derivative instruments and interest rate swap agreements and also classifies such amounts as either current or noncurrent, based on the net fair value position with each of the Company's counterparties in the unaudited Condensed Consolidated Balance Sheet.

The Company's application of its netting policy associated with cash collateral differs depending on whether its derivative instruments are in a net asset position or a net liability position. If its fuel derivative instruments are in a net asset position with a counterparty, cash collateral amounts held are first netted against current outstanding derivative amounts associated with that counterparty until that balance is zero, and then any remainder is applied against the fair value of noncurrent outstanding derivative instruments. If the Company's fuel derivative instruments are in a net liability position with the counterparty, cash collateral amounts provided are first netted against noncurrent outstanding derivative amounts associated with that counterparty until that balance is zero, and then any remainder is applied against the fair value of current outstanding derivative instruments. At June 30, 2013 , $ 65 million in cash collateral deposits had been provided by the Company associated with its outstanding fuel derivative instruments. No letters of credit or aircraft collateral were provided by or held by the Company at June 30, 2013 . At December 31, 2012 , no cash collateral deposits, letters of credit, and/or aircraft collateral were provided by or held by the Company associated with its outstanding fuel derivative instruments.

The Company also has agreements with each of its counterparties associated with its outstanding interest rate swap agreements in which cash collateral may be required based on the fair value of outstanding derivative instruments, as well as the Company's and its counterparty's credit ratings. The Company has also elected to present its interest rate swap agreement cash collateral utilizing a net presentation. As of June 30, 2013 , $39 million had been provided to one counterparty associated with interest rate derivatives based on the Company's outstanding net liability derivative position with that counterparty. In addition, in connection with interest rate swaps entered into by AirTran, $2 million had been provided to one counterparty at June 30, 2013 , as a result of the outstanding net liability derivative position with that counterparty. The outstanding interest rate net derivative positions with all other counterparties at June 30, 2013 , were assets to the Company.

The Company has the following recognized financial assets and financial liabilities resulting from those transactions that meet the scope of the disclosure requirements as necessitated by applicable accounting guidance for balance sheet offsetting:

The Company also recorded expense associated with premiums paid for fuel derivative contracts that settled/expired during the three months ended June 30, 2013 and 2012 of $12 million and $12 million , respectively, and the six months ended June 30, 2013 and 2012 of $17 million and $18 million , respectively. These amounts are excluded from the Company’s measurement of effectiveness for related hedges and are included as a component of Other (gains) losses, net, in the unaudited Condensed Consolidated Statement of Comprehensive Income.

The fair values of the derivative instruments, depending on the type of instrument, were determined by the use of present value methods or option value models with assumptions about commodity prices based on those observed in underlying markets or provided by third parties. Included in the Company’s cumulative net unrealized losses from fuel hedges as of June 30, 2013 , were approximately $101 million in unrealized losses , net of taxes, which are expected to be realized in earnings during the twelve months subsequent to June 30, 2013 . In addition, as of June 30, 2013 , the Company had already recognized cumulative net gains due to ineffectiveness and derivatives that did not qualify for hedge accounting treatment totaling $32 million , net of taxes. These net gains were recognized during the three months ended June 30, 2013 and prior periods, and are reflected in Retained earnings as of June 30, 2013 , but the underlying derivative instruments will not expire/settle until third quarter 2013 or future periods.

Interest rate swaps

The Company is party to certain interest rate swap agreements that are accounted for as either fair value hedges or cash flow hedges, as defined in the applicable accounting guidance for derivative instruments and hedging. The interest rate swap agreements accounted for as fair value hedges qualify for the “shortcut” method of accounting for hedges, which dictates that the hedges are assumed to be perfectly effective, and, thus, there is no ineffectiveness to be recorded in earnings. For the Company’s interest rate swap agreements accounted for as cash flow hedges, ineffectiveness is required to be measured at each reporting period. The ineffectiveness associated with all of the Company’s, including AirTran’s, interest rate cash flow hedges for all periods presented was not material.

Credit risk and collateral

Credit exposure related to fuel derivative instruments is represented by the fair value of contracts that are an asset to the Company at the reporting date. At such times, these outstanding instruments expose the Company to credit loss in the event of nonperformance by the counterparties to the agreements. However, the Company has not experienced any significant credit loss as a result of counterparty nonperformance in the past. To manage credit risk, the Company selects and periodically reviews counterparties based on credit ratings, limits its exposure with respect to each counterparty, and monitors the market position of the fuel hedging program and its relative market position with each counterparty. At June 30, 2013 , the Company had agreements with all of its active counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount based on the counterparty credit rating. The Company also had agreements with counterparties in which cash deposits, letters of credit, and/or pledged aircraft are required to be posted whenever the net fair value of derivatives associated with those counterparties exceeds specific thresholds. The following table provides the fair values of fuel derivatives, amounts posted as collateral, and applicable collateral posting threshold amounts as of June 30, 2013 , at which such postings are triggered:

6. COMPREHENSIVE INCOME (LOSS)

Comprehensive income (loss) includes changes in the fair value of certain financial derivative instruments that qualify for hedge accounting, unrealized gains and losses on certain investments, and actuarial gains/losses arising from the Company’s postretirement benefit obligation.

Other Operating Expenses

Other operating expenses consist of distribution costs, advertising expenses, personnel expenses, professional fees, and other operating costs, none of which individually exceed 10 percent of Operating expenses.

8. LEASES

On July 9, 2012, the Company signed an agreement with Delta Air Lines, Inc. and Boeing Capital Corp. to lease or sublease all 88 of AirTran's Boeing 717-200 aircraft (“B717s”) to Delta, with the first delivery expected to occur in August 2013, at a rate of approximately three B717s per month. A total of 78 of the B717s are on operating lease, eight are owned, and two are currently classified as capital leases.

The B717s add complexity to the Company's operations, as Southwest Airlines has historically operated an all-Boeing 737 fleet. From a fleet management perspective, the transition of approximately three B717s per month to Delta beginning in August 2013 allows the Company to minimize the impact of this transaction on operations, as the B717 capacity lost is expected to be replaced through the capacity gained as a result of (i) the Company's modification of the retirement dates for a portion of its 737-300 and 737-500 aircraft and (ii) its receipt of new 737 deliveries from Boeing or its acquisition of used 737s.

The Company will lease and/or sublease all 88 of the B717s to Delta at agreed-upon lease rates. In addition, the Company will pay the majority of the costs to convert the aircraft to the Delta livery and perform certain maintenance checks prior to the delivery of each aircraft. The agreement to pay these conversion and maintenance costs is a “lease incentive” under applicable accounting guidance. The sublease terms for the 78 B717s currently on operating lease and the two B717s currently classified as capital leases coincide with the Company's remaining lease terms for these aircraft from the original lessor, which range from approximately 6 years to approximately 12 years. The lease terms for the eight B717s that are owned by the Company are for a period of seven years, after which Delta will have the option to purchase the aircraft at the then-prevailing market value. The Company will account for the lease and sublease transactions with Delta as operating leases, except for the two aircraft classified by the Company as capital leases. The subleases of these two aircraft will be accounted for as direct financing leases. There are no contingent payments and no significant residual value conditions associated with the transaction.

The accounting for this transaction is based on the guidance provided for lease transactions. For the components of this transaction finalized in third quarter 2012 and with respect to which the lease inception has been deemed to occur, the Company recorded a charge of approximately $137 million during third quarter 2012. The charge represents the remaining estimated cost, at the scheduled date of delivery of each B717 to Delta (including the conversion, maintenance, and other contractual costs to be incurred), of the Company's lease of the 78 B717s that are currently accounted for as operating leases, net of the future sublease income from Delta and the remaining unfavorable aircraft lease liability established as of the acquisition date. The charges recorded by the Company for this transaction were included as a component of Acquisition and integration costs in the Company's unaudited Condensed Consolidated

Statement of Comprehensive Income and were included as a component of Other, net in Cash flows from operating activities in the Company's unaudited Condensed Consolidated Statement of Cash Flows, and the corresponding liability for this transaction is included as a component of Current liabilities and Other noncurrent liabilities in the Company's unaudited Condensed Consolidated Balance Sheet. See Note 2 for further information on the Company's Acquisition and integration costs. The Company may also incur other costs associated with this transaction, such as contract termination costs with certain aircraft maintenance vendors. Two of these vendor maintenance contracts have stated termination penalties totaling approximately $ 106 million if the Company were to terminate such contracts; however, termination of these contracts has not occurred, and any charges would only be recorded at the time of contract termination or at the time any associated charges become probable and estimable.

9. COMMITMENTS AND CONTINGENCIES

Commitments

During 2008, the City of Dallas approved the Love Field Modernization Program (“LFMP”), a project to reconstruct Dallas Love Field (“Airport”) with modern, convenient air travel facilities. Pursuant to a Program Development Agreement (“PDA”) with the City of Dallas and the Love Field Airport Modernization Corporation (or “LFAMC,” a Texas non-profit “local government corporation” established by the City to act on the City's behalf to facilitate the development of the LFMP), the Company is managing this project. Major construction commenced during 2010. New ticketing and checkin areas opened during fourth quarter 2012, and 11 new gates and new concessions opened on April 16, 2013. Another new gate opened in July 2013, and full completion of the project is scheduled for second half 2014. The project consists of the complete replacement of gate facilities with a new 20-gate facility, including infrastructure, systems and equipment, aircraft parking apron, fueling system, roadways and terminal curbside, baggage handling systems, passenger loading bridges and support systems, and other supporting infrastructure.

It is currently expected that the total construction costs associated with the LFMP project will be approximately $ 519 million . Although the City of Dallas has received commitments from various sources that are expected to fund portions of the LFMP project, including the Federal Aviation Administration (“FAA”), the Transportation Security Administration, and the City's Aviation Fund, the majority of the funds used are from the issuance of bonds. During fourth quarter 2010, $ 310 million of such bonds were issued by the LFAMC, and the Company has guaranteed principal and interest payments on the bonds. An additional tranche of such bonds totaling $ 146 million was issued during second quarter 2012, and the Company has guaranteed the principal and interest payments on these bonds as well. The Company currently expects that as a result of the funding commitments from the above mentioned sources and the bonds that have been issued thus far, no further bond issuances and related guarantees from the Company will be required to complete the LFMP project.

In conjunction with the Company's significant presence at Dallas Love Field, its rights to occupy 16 of the available gates upon completion of the facility, and other factors, the Company agreed to manage the majority of the LFMP project. Based on these facts, the Company has evaluated its ongoing accounting requirements in consideration of accounting guidance provided for lessees involved in asset construction. The Company has recorded and will continue to record an asset and corresponding obligation for the cost of the LFMP project as the construction of the facility occurs. As of June 30, 2013 , the Company had recorded LFMP construction costs of $ 404 million classified as both an asset as a component of Ground property and equipment and a corresponding liability as a component of Other non-current liabilities, respectively, in its unaudited Condensed Consolidated Balance Sheet. Upon completion of different phases of the LFMP project, the Company has placed the associated assets in service and has begun depreciating the assets over their estimated useful lives. The amount of depreciation recorded for the three and six months ended June 30, 2013 , associated with the LFMP project was not material. The corresponding LFMP liabilities will be reduced primarily through the Company's airport rental payments to the City of Dallas as the construction costs of the project are passed through to the Company via recurring airport rates and charges.

Contingencies

The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business, including, but not limited to, examinations by the IRS. The Company's management does not expect that

10. FAIR VALUE MEASUREMENTS

Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of June 30, 2013 , the Company held certain items that are required to be measured at fair value on a recurring basis. These included cash equivalents, short-term investments (primarily treasury bills, commercial paper, and certificates of deposit), certain noncurrent investments, interest rate derivative contracts, fuel derivative contracts, and available-for-sale securities. The majority of the Company’s short-term investments consist of instruments classified as Level 1. However, the Company has certificates of deposit, commercial paper, and Eurodollar time deposits that are classified as Level 2, due to the fact that the fair value for these instruments is determined utilizing observable inputs in non-active markets. Noncurrent investments consist of certain auction rate securities, primarily those collateralized by student loan portfolios, which are guaranteed by the U.S. Government. Other available-for-sale securities primarily consist of investments associated with the Company’s excess benefit plan.

The Company’s fuel and interest rate derivative instruments consist of over-the-counter contracts, which are not traded on a public exchange. Fuel derivative instruments include swaps, as well as different types of option contracts, whereas interest rate derivatives consist solely of swap agreements. See Note 5 for further information on the Company’s derivative instruments and hedging activities. The fair values of swap contracts are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Therefore, the Company has categorized these swap contracts as Level 2. The Company’s Treasury Department, which reports to the Chief Financial Officer, determines the value of option contracts utilizing an option pricing model based on inputs that are either readily available in public markets, can be derived from information available in publicly quoted markets, or are provided by financial institutions that trade these contracts. The option pricing model used by the Company is an industry standard model for valuing options and is the same model used by the broker/dealer community (i.e., the Company’s counterparties). The inputs to this option pricing model are the option strike price, underlying price, risk free rate of interest, time to expiration, and volatility. Because certain inputs used to determine the fair value of option contracts are unobservable (principally implied volatility), the Company has categorized these option contracts as Level 3. Volatility information is obtained from external sources, but is analyzed by the Company for reasonableness and compared to similar information received from other external sources. The fair value of option contracts considers both the intrinsic value and any remaining time value associated with those derivatives that have not yet settled. The Company also considers counterparty credit risk and its own credit risk in its determination of all estimated fair values. To validate the reasonableness of the Company’s option pricing model, on a monthly basis, the Company compares its option valuations to third party valuations. If any significant differences were to be noted, they would be researched in order to determine the reason. However, historically, no significant differences have been noted. The Company has consistently applied these valuation techniques in all periods presented and believes it has obtained the most accurate information available for the types of derivative contracts it holds.

The Company’s investments associated with its excess benefit plan consist of mutual funds that are publicly traded and for which market prices are readily available. This plan is a non-qualified deferred compensation plan designed to hold Employee contributions in excess of limits established by Section 415 of the Internal Revenue Code of 1986, as amended. Payments under this plan are made based on the participant’s distribution election and plan balance. Assets related to the funded portion of the deferred compensation plan are held in a rabbi trust, and the Company remains liable to these participants for the unfunded portion of the plan. The Company records changes in the fair value of the liability and the asset in the Company’s earnings.

All of the Company’s auction rate security instruments, totaling $ 36 million (net) at June 30, 2013 , are classified as available-for-sale securities and are reflected at their estimated fair value in the unaudited Condensed Consolidated Balance Sheet. In prior periods, due to the auction process which took place every 30 - 35 days for most securities, quoted market prices were readily available, which would have qualified as Level 1. However, due to events in credit markets beginning during first quarter 2008, the auction events for these remaining instruments failed, and have continued to fail through the current period. Therefore, the Company’s Treasury Department determines the estimated fair values of these securities utilizing a discounted cash flow analysis. The Company has performed, and routinely updates, a valuation for each of its auction rate security instruments, considering, among other items, the collateralization underlying the security investments, the expected future cash flows, including the final maturity, associated with the securities, estimates of the next time the security is expected to have a successful auction or return to full par value, forecasted reset rates based on the London Interbank Offered Rate (“LIBOR”) or the issuer’s net loan rate, and a counterparty credit spread. To validate the reasonableness of the Company’s discounted cash flow analyses, the Company compares its valuations to third party valuations on a quarterly basis.

In association with its estimate of fair value related to auction rate security instruments as of June 30, 2013 , the Company has previously recorded a temporary unrealized decline in fair value of $ 14 million , with an offsetting entry to AOCI. The Company continues to believe that this decline in fair value is due entirely to market liquidity issues, because the underlying assets for the majority of these auction rate securities held by the Company are currently rated investment grade by Moody’s, Standard and Poor’s, and Fitch and are almost entirely backed by the U.S. Government. The range of maturities for the Company’s auction rate securities are from 5 years to 34 years. Considering the relative insignificance of these securities in comparison to the Company’s liquid assets and other sources of liquidity, the Company has no current intention of selling these securities nor does it expect to be required to sell these securities before a recovery in their cost basis. At the time of the first failed auctions during first quarter 2008, the Company held a total of $463 million in auction rate securities and, since that time, has been able to sell $ 413 million of these instruments at par value.

The significant unobservable input used in the fair value measurement of the Company’s derivative option contracts is implied volatility. Holding other inputs constant, a significant increase (decrease) in implied volatility would result in a significantly higher (lower) fair value measurement, respectively, for the Company’s derivative option contracts. The significant unobservable inputs used in the fair value measurement of the Company’s auction rate securities are time to principal recovery, an illiquidity premium, and counterparty credit spread. Holding other inputs constant, a significant increase (decrease) in such unobservable inputs would result in a significantly lower (higher) fair value measurement, respectively.

The following table presents a range of the unobservable inputs utilized in the fair value measurements of the Company’s assets and liabilities classified as Level 3 at June 30, 2013 :

All settlements from fuel derivative contracts that are deemed “effective” are included in Fuel and oil expense in the period the underlying fuel is consumed in operations. Any “ineffectiveness” associated with hedges, including amounts that settled in the current period (realized), and amounts that will settle in future periods (unrealized), is recorded in earnings immediately as a component of Other (gains) losses, net. See Note 5 for further information on hedging. Any gains and losses (realized and unrealized) related to other investments are reported in Other operating expenses and were immaterial for the three and six months ended June 30, 2013 and 2012 .

The carrying amounts and estimated fair values of the Company’s long-term debt (including current maturities), as well as the applicable fair value hierarchy tier, at June 30, 2013 , are presented in the table below. The fair values of the Company’s publicly held long-term debt are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets; therefore, the Company has categorized these agreements as Level 2. Six of the Company’s debt agreements are not publicly held. The Company has determined the estimated fair value of this debt to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes indicative pricing from counterparties and a discounted cash flow method to estimate the fair value of the Level 3 items.

Note Regarding Use of Non-GAAP Financial Measures

The Company's unaudited Condensed Consolidated Financial Statements are prepared in accordance with GAAP. These GAAP financial statements include (i) unrealized non-cash adjustments and reclassifications, which can be significant, as a result of accounting requirements and elections made under accounting pronouncements relating to derivative instruments and hedging and (ii) other charges the Company believes are not indicative of its ongoing operational performance.

As a result, the Company also provides financial information in this filing that was not prepared in accordance with GAAP and should not be considered as an alternative to the information prepared in accordance with GAAP. The Company provides supplemental non-GAAP financial information, including results that it refers to as "economic," which the Company's management utilizes to evaluate its ongoing financial performance and the Company believes provides greater transparency to investors as supplemental information to its GAAP results. The Company's economic financial results differ from GAAP results in that they only include the actual cash settlements from fuel hedge contracts - all reflected within Fuel and oil expense in the period of settlement. Thus, Fuel and oil expense on an economic basis reflects the Company’s actual net cash outlays for fuel during the applicable period, inclusive of settled fuel derivative contracts. Any net premium costs paid related to option contracts are reflected as a component of Other (gains) losses, net, for both GAAP and non-GAAP (including economic) purposes in the period of contract settlement. The Company believes these economic results provide a better measure of the impact of the Company's fuel hedges on its operating performance and liquidity since they exclude the unrealized, non-cash adjustments and reclassifications that are recorded in GAAP results in accordance with accounting guidance relating to derivative instruments, and they reflect all cash settlements related to fuel derivative contracts within Fuel and oil expense. This enables the Company's management, as well as investors, to consistently assess the Company's operating performance on a year-over-year or quarter-over-quarter basis after considering all efforts in place to manage fuel expense. However, because these measures are not determined in accordance with GAAP, such measures are susceptible to varying calculations and not all companies calculate the measures in the same manner. As a result, the aforementioned measures, as presented, may not be directly comparable to similarly titled measures presented by other companies.

Further information on (i) the Company's fuel hedging program, (ii) the requirements of accounting for derivative instruments, and (iii) the causes of hedge ineffectiveness and/or mark-to-market gains or losses from derivative instruments is included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012 , and Note 5 to the unaudited Condensed Consolidated Financial Statements.

In addition to its “economic” financial measures, as defined above, the Company has also provided other non-GAAP financial measures, including results that it refers to as "excluding special items," as a result of items that the Company believes are not indicative of its ongoing operations. These include expenses associated with the Company’s acquisition and integration of AirTran. The Company believes that evaluation of its financial performance can be enhanced by a presentation of results that exclude the impact of these items in order to evaluate the results on a comparative basis with results in prior periods that do not include such items and as a basis for evaluating operating results in future periods. As a result of the Company’s acquisition of AirTran, which closed on May 2, 2011, the Company has incurred and expects to continue to incur substantial charges associated with integration of the two companies. While the Company cannot predict the exact timing or amounts of such charges, it does expect to treat these charges as special items in its future presentation of non-GAAP results. See Note 2 and Note 8 to the unaudited Condensed Consolidated Financial Statements for further information on the AirTran acquisition.

See the previous Note Regarding Use of Non-GAAP Financial Measures.

The Company's GAAP results for both the three and six months ended June 30, 2013 and 2012 were significantly impacted by the non-cash adjustments recorded as a result of the Company's portfolio of future derivative contracts utilized to hedge against jet fuel price volatility, as well as acquisition and integration costs associated with the Company's 2011 acquisition of AirTran. See Note 5 to the unaudited Condensed Consolidated Financial Statements for further information on fuel hedging and Note 2 for further information on the acquisition of AirTran. Excluding the impact of these items, the Company's net income on a non-GAAP basis for the second quarter of 2013 increased slightly versus the same period of 2012 to a Company record $274 million . For the six months ended June 30, 2013 , also on a non-GAAP basis, the Company's net income increased 29 percent compared to the same prior year period, due primarily to a combination of higher passenger revenues and lower fuel costs.

The Company continued to make progress in second quarter 2013 on its five major strategic initiatives, which include:


1.	The complete integration of AirTran into Southwest's operations by the end of 2014;


2.	The continued growth of Southwest's Rapid Rewards frequent flyer program;


3.	The continued addition of the Boeing 737-800, a larger aircraft, within the Company's fleet;


4.	The modernization of the Company's entire fleet to produce both better revenue and cost efficiencies; and


5.	The design and building of a new reservations system and international capabilities.

The Company reached a major milestone by completing the connection of the Southwest and AirTran networks during second quarter 2013. As of April 14th, Customers can now fly between any of the combined 97 Southwest and AirTran destinations on a single itinerary. During second quarter 2013, the Company also completed the conversion of five additional AirTran cities to the Southwest network-Charlotte, North Carolina; Rochester, New York; Flint, Michigan; Portland, Maine; and Wichita, Kansas. Also, on April 14, 2013, Southwest began daily service to San Juan, Puerto Rico, from Orlando and Tampa Bay, Florida, Southwest's first scheduled service outside of the continental United States. These flights are in addition to AirTran's existing service between San Juan and Atlanta, Georgia, Baltimore/Washington, and Fort Lauderdale/Hollywood, Florida. With respect to its AirTran integration initiative, the Company is experiencing substantial financial benefits associated with the recent connection of the Southwest and AirTran networks. The Company estimates it achieved approximately $95 million in net synergies during second quarter 2013, and continues to make progress towards its goal of producing approximately $400 million in total annualized net synergies from the AirTran acquisition by the end of 2013.

One of the next large phases of the Company's integration effort will be to optimize its operations in Atlanta in the fall of 2013. The Company will be transitioning Atlanta to a point-to-point operation, similar to other large Southwest cities, which is expected to enable efficiencies related to the scheduling of aircraft, flight crews, and ground staff.

The Company added three more of the larger 737-800 aircraft to its active fleet during the second quarter of 2013 . The 737-800 aircraft provides both improved revenue opportunities and operational flexibility. As of June 30, 2013, the Company's fleet included 43 of the 737-800s, all of which have been placed in service over the last 15 months. During second quarter of 2013 , the Company also continued to modernize its fleet through (i) the lease of one additional used 737-700 from a third party which is currently expected to enter active service during third quarter 2013, (ii) the retirement of two older Boeing 737-300s from the Company's fleet, (iii) the transition of one Boeing 717-200 out of active service as part of the Company's lease/sublease agreement with Delta, (iv) the retrofit of an additional 44 Southwest 737-700s with the Company's new Evolve interior, which completed the retrofitting of the Southwest 737-700 fleet, and (v) the retrofit of 14 of the planned 78 737-300 aircraft with the Company's new Evolve interior, with the remaining 64 expected to be completed in late 2013. The Company also converted one AirTran 737-700 to the Southwest livery during the second quarter of 2013.

The Company also continues to return significant value to its Shareholders. During second quarter 2013 , the Company announced and completed an accelerated share repurchase program for approximately $ 251 million , or approximately 18 million shares, which brings total share repurchases during the first six months of 2013 to approximately $ 351 million , or approximately 27 million shares. The accelerated share repurchase was part of a total share repurchase authorization of $1.5 billion , of which approximately $ 975 million , or approximately 100 million shares, has now been completed in aggregate. During second quarter 2013 , the Company's Board of Directors also authorized a four-fold increase in the Company's quarterly common stock dividend, from $.01 per share to $.04 per share. On an annualized basis, this new dividend amount provides an approximate $100 million return to Shareholders.

At the current time, the Company plans to continue its route network and schedule optimization efforts, but does not intend to grow its overall fleet size for 2013. During the second half of 2013, the Company currently expects to receive an additional nine new 737-800 aircraft from Boeing. During 2013, the Company also expects to continue to retire some of its older 737-300 and 737-500 aircraft, and transition a number of 717-200 aircraft out of the fleet as part of the Company's lease/sublease agreement with Delta. See Note 8 to the unaudited Condensed Consolidated Financial Statements. The Company currently expects 2013 ASMs to increase a modest two percent compared to ASMs flown during 2012 as a result of larger gauge aircraft. For 2014, the Company currently plans to keep its capacity in line with 2013 as it continues to optimize its network and execute on its strategic plan.

Comparison of three months ended June 30, 2013 to three months ended June 30, 2012

Operating Revenues

Operating revenues for second quarter 2013 increase d by $ 27 million , or 0.6 percent, compared to second quarter 2012 . The majority of the increase was due to a $ 33 million , or 0.8 percent, increase in Passenger revenues. The Company believes the lingering effects of government sequestration and higher taxes continued to be a drag on year-over-year revenue trends. In addition, the Company has a greater number of markets under development as the Company is in the midst of integrating AirTran, launching new city-pairs, and optimizing the combined networks. However, second quarter revenues and passenger traffic still reached Company record levels. The Company maintained strong load factors and ended the quarter with a record June load factor of 85.0 percent, which is notable considering the increasing mix of larger gauge 737-800 aircraft and Evolve -700 aircraft. The Company's addition of the larger gauge 737-800 aircraft over the past 15 months as well as the increased seat density created by the additional seats added to the Company's fleet from Evolve retrofits were contributing factors to the 2.4 percent year-over-year decline in unit revenues. However, as a result of the improvement in unit costs from the increased seating capacity, the Company believes these initiatives had a net positive impact to its second quarter operating results. Despite the 2.4 percent year-over-year decline in second quarter unit revenues, trends improved throughout the quarter. Third quarter 2013 revenue trends are encouraging thus far. July unit revenues are above last year's July, benefiting from the connection of the Southwest and AirTran networks and the Company's continued network optimization, current bookings for the remainder of the third quarter also look solid.

During second quarter 2013, Southwest announced its implementation of a No Show policy that applies to nonrefundable fares that are not canceled or changed by a Customer at least ten minutes prior to a flight's scheduled departure. If a Customer has booked a nonrefundable fare anywhere in his/her itinerary and that portion of the flight is not used and not canceled or changed by the Customer at least ten minutes prior to scheduled departure, all unused funds on the full itinerary will be lost, and the remaining reservation will be canceled. The policy applies to reservations made or changed on or after Friday, May 10, 2013, for travel on or after Friday, September 13, 2013. This policy does not apply to military fares, senior fares, or travel during certain irregular operations, including severe weather conditions. The No Show policy will not impact Customers who simply cancel a Wanna Get Away® or DING!® fare at least ten minutes prior to scheduled departure; in this case, Customers may reuse their funds toward future travel on Southwest, without a change fee, as they have always done. Customers who are traveling on a fully refundable itinerary that does not contain a Wanna Get Away or DING! fare will continue to have the option of either requesting a refund or holding funds for future travel. Based on the Company's revenue recognition policy, revenue would be recorded at the flight date for a Customer that does not change his/her itinerary and loses their funds. The Company is unable to estimate the impact of this change in policy on future Passenger revenues at the current time.

Freight revenues for second quarter 2013 increase d by $ 1 million , or 2.4 percent, compared to second quarter 2012 , primarily due to an increase in rates charged versus second quarter 2012 . Other revenues for second quarter 2013 decrease d by $ 7 million , or 3.1 percent, compared to second quarter 2012 , primarily due to a decline in ancillary revenues. The majority of the decline in ancillary revenues was due to the conversion of AirTran aircraft into the Southwest livery and the adoption of Southwest fee policies for a larger portion of Customers. The Company currently expects such trend to continue as the integration process continues, and intends, upon full integration of AirTran, to have a consistent product offering. Based on current trends, the Company expects third quarter 2013 Freight and Other revenues will decrease from third quarter 2012 .

Operating expenses

Operating expenses for second quarter 2013 increase d by $ 54 million , or 1.3 percent, compared to second quarter 2012 , while capacity increase d 3.0 percent over the same prior year period. Historically, except for changes in the price of fuel, changes in Operating expenses for airlines are largely driven by changes in capacity, or ASMs. The following table presents the Company's Operating expenses per ASM for the second quarter s of 2013 and 2012 , followed by explanations of these changes on a per-ASM basis and/or on a dollar basis:



	Three months ended June 30,						Per-ASM			Percent
(in cents, except for percentages)	2013			2012			change			change
Salaries, wages, and benefits		3.79	¢		3.68	¢		0.11	¢	3.0	%
Fuel and oil	4.35			4.75			(0.40		)	(8.4	)
Maintenance materials and repairs	0.82			0.87			(0.05		)	(5.7	)
Aircraft rentals	0.27			0.27			—			—
Landing fees and other rentals	0.85			0.78			0.07			9.0
Depreciation and amortization	0.62			0.61			0.01			1.6
Acquisition and integration	0.08			0.03			0.05			166.7
Other operating expenses	1.52			1.52			—			—
Total		12.30	¢		12.51	¢		(0.21	)¢	(1.7	)%

On a dollar basis, Operating expenses increase d by 1.3 percent for second quarter 2013 compared to second quarter 2012 , primarily due to higher Salaries, wages, and benefits expenses and higher Landing fees and other rentals, but were largely offset by lower fuel costs. Operating expenses per ASM (unit costs) for second quarter 2013 decrease d 1.7 percent compared to second quarter 2012 , primarily due to a decrease in Fuel and oil expense. On a non-GAAP basis, the Company's second quarter 2013 Operating expenses per ASM, excluding fuel and special items, increase d 1.8 percent compared to second quarter 2012 , primarily due to higher Salaries, wages, and benefits expenses. Based

on current cost trends and benefits from our fleet modernization efforts, the Company expects third quarter 2013 unit costs, excluding fuel, special items, and profitsharing, to increase slightly from t hird quarter 2012 's 7.72 cents. See the previous Note Regarding Use of Non-GAAP Financial Measures.

Salaries, wages, and benefits expense for second quarter 2013 increase d by $ 76 million , or 6.2 percent, compared to second quarter 2012 . Salaries, wages, and benefits expense per ASM for second quarter 2013 increase d 3.0 percent compared to second quarter 2012 . On both a dollar and a per ASM basis, approximately 40 percent of the increase was a result of higher contractual wage rates for a large portion of the Company's unionized workforce compared to second quarter 2012. The remainder of the increase was due to a variety of smaller items, including additional headcount associated with more Boeing 737-800s added to the Company's fleet over the past 12 months, as those are larger gauge aircraft which require the presence of a fourth flight attendant for each trip, and additional flight crew training costs incurred in preparation for future Southwest overwater and international flights. Based on current cost trends and anticipated capacity, the Company expects Salaries, wages, and benefits expense per ASM in third quarter 2013 , excluding profitsharing, to be comparable to second quarter 2013 's Salaries, wages, and benefits expense per ASM, excluding profitsharing.

Fuel and oil expense for second quarter 2013 decrease d by $ 88 million , or 5.6 percent, compared to second quarter 2012 . On a per-ASM basis, second quarter 2013 Fuel and oil expense decrease d 8.4 percent versus second quarter 2012 . Excluding the impact of hedging in both periods, both the nominal dollar and unit cost decreases were attributable to a lower fuel cost per gallon and to better efficiency. Approximately 80 percent of the dollar change was attributable to a lower fuel cost per gallon, and approximately 20 percent was related to better fuel efficiency. The Company's average economic jet fuel cost per gallon, including fuel tax, decrease d 5.0 percent on a year-over-year basis, from $ 3.22 in second quarter 2012 to $ 3.06 in second quarter 2013 . In addition, fuel gallons consumed decrease d 1.0 percent compared to second quarter 2012 , while year-over-year capacity increase d 3.0 percent. The improvement in fuel efficiency was primarily due to the Company's continued replacement of older Classic (737-300s and 737-500s) aircraft with new Next Generation 737s. As a result of the Company's fuel hedging program and inclusive of accounting for derivatives and hedging, the Company recognized net losses totaling $ 47 million in second quarter 2013 in Fuel and oil expense relating to fuel derivative instruments versus net losses totaling $ 33 million recognized in Fuel and oil expense in second quarter 2012 . These totals are inclusive of cash settlements realized from the expiration/settlement of fuel derivatives, which were $ 27 million paid to counterparties in second quarter 2013 versus $ 19 million paid to counterparties in second quarter 2012 . These totals exclude gains and/or losses recognized from hedge ineffectiveness and from derivatives that do not qualify for hedge accounting, which impacts are recorded as a component of Other (gains) losses, net. See Note 5 to the unaudited Condensed Consolidated Financial Statements.

As of July 22, 2013 , on an economic basis, the Company had derivative contracts in place related to expected future fuel consumption as follows:



		Average percent of estimated fuel consumption
		covered by fuel derivative contracts at
Period		varying WTI/Brent crude-equivalent price levels
Second half 2013		Approx. 80% to 85%
2014		Approx. 35%
2015		Approx. 35%
2016		Approx. 30%
2017		Approx. 50%

As a result of applying hedge accounting in prior periods the Company has amounts “frozen” in Accumulated other comprehensive income (loss) (“AOCI”), and these amounts will be recognized in earnings in future periods when the underlying fuel derivative contracts settle. The following table displays the Company's estimated fair value of remaining fuel derivative contracts (not considering the impact of the cash collateral provided to or received from counterparties- See Note 5 to the unaudited Condensed Consolidated Financial Statements for further information), as well as the

amount of deferred gains/losses in AOCI at June 30, 2013 , and the expected future periods in which these items are expected to settle and/or be recognized in earnings (in millions):



Year	Fair value (liability) of fuel derivative contracts at June 30, 2013			Amount of gains (losses) deferred in AOCI at June 30, 2013 (net of tax)
Remainder of 2013	$	(93	)	$	(93	)
2014	50			(18		)
2015	(9		)	(71		)
2016	16			(24		)
2017	(56		)	(13		)
Total	$	(92	)	$	(219	)

Based on forward market prices and the amounts in the above table (and excluding any other subsequent changes to the fuel hedge portfolio), the Company's jet fuel costs per gallon could exceed market (i.e., unhedged) prices during some of these future periods. This is based primarily on expected future cash settlements associated with fuel derivatives, but excludes any impact associated with the ineffectiveness of fuel hedges or fuel derivatives that are marked to market because they do not qualify for hedge accounting. See Note 5 to the unaudited Condensed Consolidated Financial Statements for further information. Assuming no changes to the Company's current fuel derivative portfolio, but including all previous hedge activity for fuel derivatives that have not yet settled, and considering only the expected net cash payments related to hedges that will settle, the Company is providing a sensitivity table for third quarter 2013 , fourth quarter 2013, and full year 2013 jet fuel prices at different crude oil assumptions as of July 22, 2013 , and for expected premium costs associated with settling contracts each period.



	Estimated economic jet fuel price per gallon, including taxes
Average Brent Crude Oil price per barrel	3Q 2013 (2)	4Q 2013	Full Year 2013
$85	$2.85 - $2.90	$2.85 - $2.90	$3.00 - $3.05
$95	$2.90 - $2.95	$2.90 - $2.95	$3.05 - $3.10
Current Market (1)	$3.05 - $3.10	$3.05 - $3.10	$3.10 - $3.15
$115	$3.15 - $3.20	$3.25 - $3.30	$3.20 - $3.25
$125	$3.25 - $3.30	$3.35 - $3.40	$3.25 - $3.30
Estimated Premium Costs (3)	$22 million	$22 million	$60 million

(1) Brent crude oil average market prices as of July 22, 2013 were approximately $ 107 and $ 105 per barrel for third and fourth quarter 2013, respectively.

(2) The Company has approximately 80 percent of its third quarter 2013 estimated fuel consumption covered by fuel derivative contracts with approximately 70 percent at varying Gulf Coast jet fuel-equivalent prices and the remainder at varying Brent crude oil-equivalent prices. The Company has approximately 85 percent of its fourth quarter 2013 estimated fuel consumption covered by fuel derivative contracts with approximately 75 percent at varying Gulf Coast jet fuel-equivalent prices and the remainder at varying Brent crude oil-equivalent prices. The economic fuel price per gallon sensitivities provided above assume the relationship between Brent crude oil and refined products based on market prices as of July 22, 2013.

(3) Premium costs are recognized as a component of Other (gains) losses net.

Maintenance materials and repairs expense for second quarter 2013 decrease d by $ 10 million , or 3.4 percent, compared to second quarter 2012 . On a per-ASM basis, Maintenance materials and repairs expense for second quarter 2013 decrease d 5.7 percent compared to second quarter 2012 . These decreases were primarily attributable to fewer second quarter 2013 engine repairs associated with the Company's 737-300 and 737-500 fleet. The Company currently expects Maintenance materials and repairs expense per ASM for third quarter 2013 to be comparable to second quarter 2013 based on currently scheduled aircraft maintenance events.

Aircraft rentals expense for second quarter 2013 increase d by $ 2 million , or 2.2 percent, compared to second quarter 2012 , primarily due to expense associated with five Boeing 737-800 aircraft received in the latter part of second quarter 2012 that are accounted for as operating leases. On a per-ASM basis compared to second quarter 2012 , Aircraft rentals expense in second quarter 2013 was relatively flat . The Company currently expects Aircraft rentals expense per ASM for third quarter 2013 to be comparable to second quarter 2013 .

Landing fees and other rentals expense for second quarter 2013 increase d by $ 32 million , or 12.3 percent, compared to second quarter 2012 . On a per-ASM basis compared to second quarter 2012 , Landing fees and other rentals expense increase d 9.0 percent. The majority of these increases were due to higher rental rates charged by several airports over the last twelve months, a portion of which was due to additional space occupied by the Company in some locations, and a portion of which was attributable to higher debt service costs passed through to the airlines in certain cities. The Company currently expects Landing fees and other rentals expense per ASM for third quarter 2013 to increase compared to third quarter 2012 as the escalation in airport costs is expected to be only partially offset by a year-over-year increase in ASMs.

Depreciation and amortization expense for second quarter 2013 increase d by $ 11 million , or 5.4 percent, compared to second quarter 2012 . On a per-ASM basis, Depreciation and amortization expense increase d 1.6 percent compared to second quarter 2012 . Both of these increases were primarily due to depreciation associated with large software projects that have been placed into service over the past twelve months. For third quarter 2013 , the Company currently expects Depreciation and amortization expense per ASM to be comparable to third quarter 2012 .

For second quarter 2013 , the Company incurred $ 26 million of Acquisition and integration costs related to the acquisition of AirTran compared to $ 11 million in second quarter 2012 . The second quarter 2013 costs primarily consisted of Employee training, technology integration projects, and facility integration expenses. See Note 2 to the unaudited Condensed Consolidated Financial Statements.

Other operating expenses for second quarter 2013 increase d by $ 16 million , or 3.2 percent, compared to second quarter 2012 . Approximately 30 percent of this increase was the result of increased winterization costs associated with late spring storms in early second quarter 2013, and approximately 30 percent was the result of costs associated with increased Customer usage of WiFi onboard the Company's 737-700 and 737-800 aircraft. The remainder of the increase was due to immaterial individual contributors. On a per-ASM basis, Other operating expenses were comparable to second quarter 2012 . For third quarter 2013 , the Company currently expects Other operating expenses per ASM to increase as compared to third quarter 2012 .

Other

Other expenses (income) include interest expense, capitalized interest, interest income, and other gains and losses. Interest expense for second quarter 2013 decrease d by $ 5 million , or 13.2 percent, compared to second quarter 2012 , primarily due to the repayment of AirTran aircraft financing facilities during the first quarter of 2013 . For third quarter 2013 , the Company expects interest expense to be comparable to second quarter 2013 as a result of the repayment of this debt.

Other (gains) losses, net, primarily includes amounts recorded as a result of the Company's hedging activities. See Note 5 to the unaudited Condensed Consolidated Financial Statements for further information on the Company's hedging activities. The following table displays the components of Other (gains) losses, net, for the three months ended June 30, 2013 and 2012 :



	Three months ended June 30,
(in millions)	2013		2012

Income Taxes

The Company's effective tax rate was approximately 38.3 percent in second quarter 2013 , compared to 38.0 percent in second quarter 2012 . The Company currently projects a full year 2013 effective tax rate of approximately 38 to 40 percent based on currently forecasted financial results.

Comparison of six months ended June 30, 2013 to six months ended June 30, 2012

Operating Revenues

Operating revenues for the six months ended June 30, 2013 , increase d by $121 million , or 1.4 percent, compared to the first six months of 2012 . The majority of the increase was due to a $121 million , or 1.5 percent, increase in Passenger revenues. The majority of the increase in Passenger revenues was attributable to a 1.8 percent increase in capacity, as both load factor and passenger yields remained relatively flat with the same prior year period. The Company's load factor for the six months ended June 30, 2013 , was relatively flat compared to the first six months of 2012 .

Freight revenues for the six months ended June 30, 2013 , increase d by $3 million , or 3.8 percent, compared to the first six months of 2012 , primarily due to an increase in rates charged versus the prior year. Other revenues for the six months ended June 30, 2013 , decrease d by $3 million , or 0.7 percent, compared to the first six months of 2012 , primarily due to a decline in ancillary revenues. The majority of the decline in ancillary revenues was due to the conversion of AirTran aircraft into Southwest and the adoption of Southwest fee policies for a larger portion of Customers.

Operating expenses

Operating expenses for the six months ended June 30, 2013 , increase d by $99 million , or 1.2 percent, compared to the first six months of 2012 , while capacity increase d 1.8 percent over the same prior year period. Historically, except for changes in the price of fuel, changes in Operating expenses for airlines are largely driven by changes in capacity, or ASMs. The following table presents the Company's Operating expenses per ASM for the first six months of 2013 and 2012 , followed by explanations of these changes on a per-ASM basis and/or on a dollar basis:

Total		12.65	¢		12.72	¢		(0.07	)¢	(0.6	)%

On a dollar basis, Operating expenses increase d by 1.2 percent for the first six months of 2013 compared to the first six months of 2012 , primarily due to higher Salaries, wages, and benefits expenses and higher Landing fees and other rentals, but were largely offset by lower fuel costs. Operating expenses per ASM (unit costs) for the first six months of 2013 decrease d 0.6 percent compared to the first six months of 2012 , primarily due to a decrease in Fuel and oil expense. On a non-GAAP basis, the Company's Operating expenses per ASM for the first six months of 2013 , excluding fuel and special items, increase d 2.7 percent compared to the first six months of 2012 , primarily due to higher Salaries, wages, and benefits expenses. See the previous Note Regarding Use of Non-GAAP Financial Measures.

Salaries, wages, and benefits expense for the six months ended June 30, 2013 , increase d by $ 118 million , or 5.0 percent, compared to the six months ended June 30, 2012 . Salaries, wages, and benefits expense per ASM for the first six months of 2013 increase d 3.0 percent compared to the first six months of 2012 . Approximately 65 percent of these increases were a result of higher contractual wage rates for a large portion of the Company's workforce compared to the six months ended June 30, 2012 , and the majority of the remaining increases were a result of higher contributions to Employee retirement plans, including profitsharing and 401(k) matching contributions. The Company’s profitsharing expense is based on profits that exclude the unrealized gains and/or losses the Company records for its fuel hedging program as well as Acquisition and integration costs.

Fuel and oil expense for the six months ended June 30, 2013 , decrease d by $ 141 million , or 4.6 percent, compared to the six months ended June 30, 2012 . On a per-ASM basis, for the first six months of 2013 , Fuel and oil expense decrease d 6.2 percent versus the first six months of 2012 . Excluding the impact of hedging in both periods, both the nominal dollar and unit cost decreases were attributable to a lower fuel cost per gallon and to better efficiency. Approximately 70 percent of the dollar change was attributable to a lower fuel cost per gallon and approximately 25 percent was related to better fuel efficiency. The Company's average economic jet fuel cost per gallon, including fuel tax, decrease d 4.8 percent on a year-over-year basis, from $ 3.33 during the six months ended June 30, 2012 , to $ 3.17 during the six months ended June 30, 2013 . In addition, fuel gallons consumed decrease d 1.7 percent compared to the six months ended June 30, 2012 , while year-over-year capacity increase d 1.8 percent. The improvement in fuel efficiency was primarily due to the Company's continued replacement of older Classic (737-300s and 737-500s) aircraft with new Next Generation 737s including 28 of the larger gauge 737-800 aircraft added into service during the last twelve months . As a result of the Company's fuel hedging program and inclusive of accounting for derivatives and hedging, the Company recognized net losses totaling $ 99 million during the six months ended June 30, 2013 in Fuel and oil expense relating to fuel derivative instruments versus net losses totaling $ 64 million recognized in Fuel and oil expense in the six months ended June 30, 2012 . These totals are inclusive of cash settlements realized from the expiration/settlement of fuel derivatives, which were $ 50 million paid to counterparties in the first six months of 2013 , versus $ 74 million paid to counterparties in the first six months of 2012 . These totals exclude gains and/or losses recognized from hedge ineffectiveness and from derivatives that do not qualify for hedge accounting, which impacts are recorded as a component of Other (gains) losses, net. See Note 5 to the unaudited Condensed Consolidated Financial Statements.

Maintenance materials and repairs expense for the six months ended June 30, 2013 , increase d by $ 9 million , or 1.6 percent, compared to the six months ended June 30, 2012 . This increase was primarily attributable to costs associated with the Company's Evolve aircraft interior retrofit program, which began in March 2012. On a per ASM basis compared to the six months ended June 30, 2012 , Maintenance materials and repairs expense in the first six months of 2013 was relatively flat .

Aircraft rentals expense for the six months ended June 30, 2013 , increase d by $ 7 million , or 3.9 percent, compared to the six months ended June 30, 2012 , primarily due to expense associated with five Boeing 737-800 aircraft received in the latter part of second quarter 2012 that are accounted for as operating leases. On a per-ASM basis compared to the six months ended June 30, 2012 , Aircraft rentals expense in the first six months of 2013 was relatively flat .

Landing fees and other rentals expense for the six months ended June 30, 2013 , increase d by $ 45 million , or 8.8 percent, compared to the six months ended June 30, 2012 . On a per-ASM basis, Landing fees and other rentals expense increase d 7.5 percent compared to the six months ended June 30, 2012 . The majority of these increase s were due to higher rental rates charged by several airports over the last twelve months, a portion of which is due to additional space occupied by the Company in some locations, and a portion of which is attributable to higher debt service costs passed through to the airlines in certain cities.

Depreciation and amortization expense for the six months ended June 30, 2013 , increase d by $ 19 million , or 4.7 percent, compared to the six months ended June 30, 2012 . Approximately 55 percent of this increase was due to depreciation associated with large software projects that have been placed into service over the past twelve months and approximately 40 percent was due to 28 737-800 aircraft being placed into service during the twelve months ended June 30, 2013 . On a per-ASM basis, Depreciation and amortization expense increase d 3.2 percent compared to the six months ended June 30, 2012 , primarily due to depreciation associated with large software projects that have been placed into service over the past twelve months.

For the six months ended June 30, 2013 , the Company incurred $ 39 million of Acquisition and integration costs related to the acquisition of AirTran compared to $ 24 million for the six months ended June 30, 2012 . These 2013 costs primarily consisted of Employee training, technology integration projects, and facility integration expenses. See Note 2 to the unaudited Condensed Consolidated Financial Statements.

Other operating expenses for the six months ended June 30, 2013 , increase d by $ 27 million , or 2.7 percent, compared to the six months ended June 30, 2012 , and increase d 1.3 percent on a per-ASM basis compared to the six months ended June 30, 2012 . Approximately 30 percent of these increases were the result of costs associated with increased Customer usage of WiFi onboard the Company's 737-700 and 737-800 aircraft and approximately 25 percent was the result of increased winterization costs at airports from more severe weather during the first six months of 2013 compared to the same period in 2012 . The remainder of the increases was due to immaterial individual contributors.

Other

Other expenses (income) include interest expense, capitalized interest, interest income, and other gains and losses. Interest expense for the six months ended June 30, 2013 , decrease d by $ 15 million , or 19.5 percent, compared to the six months ended June 30, 2012 , primarily due to the repayment of $385 million of 6.5% notes in March 2012.

Income Taxes

The Company's effective tax rate was approximately 37.9 percent for the first six months of 2013 , compared to 38.0 percent for the first six months of 2012 .

Liquidity and Capital Resources

Net cash provided by operating activities was $ 778 million for the three months ended June 30, 2013 , compared to $ 145 million provided by operating activities in the same prior year period. For the six months ended June 30, 2013 , net cash provided by operating activities was $ 1.8 billion compared to $ 1.4 billion provided by operating activities in the first six months of 2012 . The operating cash flows for the six months ended June 30, 2013 , were largely impacted by the Company's results of operations (as adjusted for noncash depreciation and amortization expense), changes in Air traffic liability, and Accounts payable and accrued liabilities. For the six months ended June 30, 2013 , in addition to the Company's net income (as adjusted for noncash depreciation and amortization expense), there was a $ 907 million increase in Air traffic liability, as a result of bookings for future travel and higher sales of points to business partners in the Company's frequent flyer program, and a net $ 282 million increase in cash flow associated with higher balances in Accounts payable and accrued liabilities due to timing of payments. For the six months ended June 30, 2012 , there was a $ 693 million increase in Air traffic liability, as a result of bookings for future travel and a net $ 301 million increase in cash flow associated with higher balances in Accounts payable and accrued liabilities due to timing of payments. See Note 5 to the unaudited Condensed Consolidated Financial Statements for further information on the Company's derivatives and hedging activities. Net cash provided by operating activities is primarily used to finance capital expenditures, repay debt, and provide working capital.

Net cash used in investing activities during the three months ended June 30, 2013 , totaled $ 300 million , versus $ 355 million used in investing activities in the same prior year period. For the six months ended June 30, 2013 , net cash used in investing activities was $ 771 million compared to $ 368 million used in the same prior year period. Investing activities in both years included payments for new aircraft delivered to the Company and progress payments for future aircraft deliveries, as well as changes in the balance of the Company's short-term investments and noncurrent investments. During the six months ended June 30, 2013 , the Company's transactions in short-term and noncurrent investments resulted in a net cash outflow o f $ 44 million , versus a net cash inflow of $ 169 million during the same prior year period.

Net cash used in financing activities during the three months ended June 30, 2013 , was $ 327 million , compared to $ 265 million used in financing activities for the same prior year period. For the six months ended June 30, 2013 , net cash used in financing activities was $ 613 million compared to $ 748 million used in the same prior year period. During the six months ended June 30, 2013 , the Company repaid $ 216 million in debt and capital lease obligations and repurchased approximately $ 351 million of its outstanding common stock through a share repurchase program. During the six months ended June 30, 2012 , the Company repaid $ 469 million in debt and capital lease obligations that came due and repurchased approximately $ 275 million of its outstanding common stock through a share repurchase program.

The Company is a “well-known seasoned issuer” and currently has an effective shelf registration statement registering an indeterminate amount of debt and equity securities for future sales. The Company currently intends to use the

proceeds from any future securities sales off this shelf registration statement for general corporate purposes. The Company has not issued any securities under this shelf registration statement to date.

On April 2, 2013, the Company entered into a new $1 billion unsecured revolving credit facility expiring in April 2018, and terminated its previous facility, which would have expired in April 2016. Other than an increased borrowing capacity, this new facility is substantially the same as the previous facility. Interest on the facility is based on the Company's credit ratings at the time of borrowing. At the Company's current ratings, the interest cost would be LIBOR plus a spread of 150 basis points. The new facility also contains the same financial covenant as the previous facility, requiring a minimum coverage ratio of adjusted pre-tax income to fixed obligations, as defined. As of June 30, 2013 , the Company was in compliance with this covenant and there were no amounts outstanding under the revolving credit facility.

Contractual Obligations and Contingent Liabilities and Commitments

The Company has contractual obligations and commitments primarily with regard to future purchases of aircraft, repayment of debt, and lease arrangements. During the six months ended June 30, 2013 , the Company purchased nine new 737-800 aircraft from Boeing, and retired from service six of its older 737-300 and 737-500 aircraft and removed one of its 717-200 aircraft from active service. In addition, the Company also leased two 737-700 aircraft from a third party which were not yet placed into service as of June 30, 2013 . During second quarter 2013, the Company announced modifications to its aircraft orders with Boeing and an agreement to purchase ten pre-owned 737-700 aircraft from a third party for delivery in 2014 and 2015. During July 2013, the Company entered into an agreement to lease two pre-owned 737-700 aircraft from a third party for delivery in 2014. The modifications with Boeing included the relinquishment of a total of ten options for Boeing Next Generation ("NG") aircraft, the exercise of five separate options for 737-800 aircraft, the conversion of five 737-700 firm orders to 737-800 deliveries, and the deferral and conversion of existing NG aircraft firm orders and options to 737 MAX options and firm orders in future years. The Company and Boeing also announced Southwest would be the launch Customer for the Boeing 737 MAX 7 series aircraft, with deliveries expected to begin in 2019 . As of July 24, 2013 , the Company had scheduled deliveries for Boeing 737-700, 737-800, 737 MAX 7, and 737 MAX 8 aircraft as follows:

The Company expects to incur no more than $ 550 million in Acquisition and integration costs associated with the AirTran acquisition, of which approximately $ 363 million has been recorded through June 30, 2013 . These costs have been, and are expected to continue to be, funded with cash from operations. The Company believes that its current liquidity position, including unrestricted cash and short-term investments of $ 3.4 billion as of June 30, 2013 , anticipated future internally generated funds from operations, and its fully available, unsecured revolving credit facility of $1 billion that expires in April 2018, will enable it to meet these future integration expenditures. However, if a liquidity need were to arise, the Company believes it has access to financing arrangements because of its current investment grade credit ratings, large value of unencumbered assets, and modest leverage, which should enable it to meet its ongoing capital, operating, and other liquidity requirements. The Company will continue to consider various borrowing or leasing options to maximize liquidity and supplement cash requirements as necessary.

In January 2008, the Company's Board of Directors authorized the repurchase of up to $ 500 million of the Company's common stock. Through February 15, 2008, the Company had repurchased 4.4 million shares for a total of approximately $ 54 million , at which time repurchases under the program were suspended. On August 5, 2011, the Company's Board of Directors authorized the Company to resume a share repurchase program and approved the Company's repurchase, on a discretionary basis, of a total of up to $ 500 million of the Company's common stock following such authorization. On May 16, 2012, the Company's Board of Directors increased the previous share repurchase authorization by $ 500 million . On May 15, 2013, the Company's Board of Directors further increased the previous share repurchase authorization by an additional $ 500 million to a total of $1.5 billion and, in a privately negotiated transaction, the Company entered into an agreement with a third party financial institution to repurchase $250 million of its common shares under an accelerated share repurchase program ("ASR Program") utilizing cash on hand. On May 15, 2013, pursuant to the ASR Program agreement, the Company advanced the $250 million to the financial institution and received approximately 17.9 million shares, which was recorded as a treasury share purchase for purposes of calculating earnings per share. The Company also made a $500 thousand additional payment to the third party financial institution under the terms of the agreement governing the ASR Program. The ASR Program was completed on June 24, 2013 , upon which a settlement of approximately 158 thousand shares were delivered to the Company. The final number of shares delivered upon settlement was determined based on a discount to the volume-weighted average price of the Company's common stock over the term of the ASR Program. Including purchases

made under the ASR Program, the Company's cumulative purchases under all Board-authorized repurchases since the August 2011 authorization have totaled approximately 100 million shares for approximately $ 975 million of the $ 1.5 billion in total authorized by the Board.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

As discussed in Note 5 to the unaudited Condensed Consolidated Financial Statements, the Company endeavors to acquire jet fuel at the lowest possible cost and to reduce volatility in operating expenses through its fuel hedging program with the use of financial derivative instruments. At June 30, 2013 , the estimated fair value of outstanding contracts, excluding the impact of cash collateral provided to or held by counterparties, was a liability of $92 million .

The Company's credit exposure related to fuel derivative instruments is represented by the fair value of contracts that are an asset to the Company. At such times, these outstanding instruments expose the Company to credit loss in the event of nonperformance by the counterparties to the agreements. As of June 30, 2013 , the Company had five counterparties with which the derivatives held were a net asset, totaling $ 40 million , and five counterparties with which the derivatives held were a net liability, totaling a net $ 132 million liability. To manage credit risk, the Company selects and periodically reviews counterparties based on credit ratings, limits its exposure with respect to each counterparty, and monitors the market position of the fuel hedging program and its relative market position with each counterparty. However, if one or more of these counterparties were in a liability position to the Company and were unable to meet their obligations, any open derivative contracts with the counterparty could be subject to early termination, which could result in substantial losses for the Company. At June 30, 2013 , the Company had agreements with all of its active counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount based on the counterparty's credit rating. The Company also had agreements with counterparties in which cash deposits, letters of credit, and/or pledged aircraft are required to be posted whenever the net fair value of derivatives associated with those counterparties exceeds specific thresholds.

At June 30, 2013 , $65 million in cash deposits and no letters of credit or aircraft collateral were provided by the Company based on its outstanding fuel derivative instrument portfolio. Due to the terms of the Company's current fuel hedging agreements with counterparties and the types of derivatives held, in the Company's judgment, it does not have significant additional exposure to future cash collateral requirements. As an example, if market prices for the commodities used in the Company's fuel hedging activities were to decrease by 25 percent from market prices as of June 30, 2013 , given the Company's current fuel derivative portfolio, its aircraft collateral facilities, and its investment grade credit rating, it would likely provide an additional $ 666 million in cash collateral, post $ 644 million in aircraft collateral, and post $ 50 million in letters of credit against these positions with its current counterparties. However, the Company would expect to also benefit from lower market prices paid for fuel used in its operations. See Note 5 to the unaudited Condensed Consolidated Financial Statements.

The Company is also subject to the risk that the fuel derivatives it uses to hedge against fuel price volatility do not provide adequate protection. A portion of the fuel derivatives in the Company's hedge portfolio are based on the market price of West Texas intermediate crude oil ("WTI"). In some periods, the spread between WTI and jet fuel has widened beyond historic norms, which has led to more ineffectiveness when measuring the Company's hedges. During those time periods, jet fuel prices have more closely correlated with changes in the price of Brent crude oil ("Brent"). The Company has attempted to mitigate some of this risk by entering into more fuel hedges based on Brent crude. Although the Company has some fuel derivatives based on the price of Brent, to the extent the spread between jet fuel and WTI continues to fluctuate, a portion of these changes in fair value of the Company's hedges could continue to experience ineffectiveness and not provide complete protection against jet fuel price volatility. In addition, to add further protection, the Company may periodically enter into jet fuel derivatives for short-term timeframes. Jet fuel is not widely traded on an organized futures exchange and, therefore, there are limited opportunities to hedge directly in jet fuel for time horizons longer than approximately six to twelve months into the future.

See Item 7A “Quantitative and Qualitative Disclosures About Market Risk” in the Company's Annual Report on Form 10-K for the year ended December 31, 2012 , for further information about market risk, and Note 5 to the unaudited

Condensed Consolidated Financial Statements in this Form 10-Q for further information about the Company's fuel derivative instruments.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934 (the "Exchange Act")) designed to provide reasonable assurance that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. These include controls and procedures designed to ensure that this information is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Management, with the participation of the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company's disclosure controls and procedures as of June 30, 2013 . Based on this evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that the Company's disclosure controls and procedures were effective as of June 30, 2013 , at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the fiscal quarter ended June 30, 2013 , that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

A complaint alleging violations of federal antitrust laws and seeking certification as a class action was filed against Delta Air Lines, Inc. (“Delta”) and AirTran in the United States District Court for the Northern District of Georgia in Atlanta on May 22, 2009. The complaint alleged, among other things, that AirTran attempted to monopolize air travel in violation of Section 2 of the Sherman Act, and conspired with Delta in imposing $15-per-bag fees for the first item of checked luggage in violation of Section 1 of the Sherman Act. The initial complaint sought treble damages on behalf of a putative class of persons or entities in the United States who directly paid Delta and/or AirTran such fees on domestic flights beginning December 5, 2008. After the filing of the May 2009 complaint, various other nearly identical complaints also seeking certification as class actions were filed in federal district courts in Atlanta, Georgia; Orlando, Florida; and Las Vegas, Nevada. All of the cases were consolidated before a single federal district court judge in Atlanta. A Consolidated Amended Complaint was filed in the consolidated action on February 1, 2010, which broadened the allegations to add claims that Delta and AirTran conspired to reduce capacity on competitive routes and to raise prices in violation of Section 1 of the Sherman Act. In addition to treble damages for the amount of first baggage fees paid to AirTran and to Delta, the Consolidated Amended Complaint seeks injunctive relief against a broad range of alleged anticompetitive activities, as well as attorneys' fees. On August 2, 2010, the Court dismissed plaintiffs' claims that AirTran and Delta had violated Section 2 of the Sherman Act; the Court let stand the claims of a conspiracy with respect to the imposition of a first bag fee and the airlines' capacity and pricing decisions. On June 30, 2010, the plaintiffs filed a motion to certify a class, which AirTran and Delta have opposed. The Court has not yet ruled on the class certification motion. The original period for fact and expert discovery was scheduled to end on February 25, 2011, but on February 3, 2012, the Court granted plaintiffs' motion for supplemental discovery because Delta discovered that it had not produced certain electronic documents. The period for supplemental discovery against AirTran ended on May 3, 2012, but discovery disputes between plaintiffs and Delta have continued. On June 18, 2012, the parties filed a Stipulation and Order that plaintiffs have abandoned their claim that AirTran and Delta conspired to reduce capacity. On August 31, 2012, AirTran and Delta moved for summary judgment on all of plaintiffs' remaining claims, and the plaintiffs filed a supplemental brief on class certification. From September to November 2012, the plaintiffs filed a series of motions to compel Delta to produce additional documents and for sanctions based on alleged failures to produ ce electronic data. On November 19, 2012, the Court ordered plaintiffs to appoint an expert to examine Delta's production of electronic data and suspended the briefing schedule for the summary judgment motion until the expert has completed his work. The expert submitted a preliminary report, disputes have arisen concerning the expert's work, and the Court is deciding how to proceed. After disputes concernin g the expert's work and Delta's discovery have been resolved, the parties will resume briefing defendants' motions for summary judgment and supplemental briefing on plaintiffs' motion for class certification. AirTran denies all allegations of wrongdoing, including those in the Consolidated Amended Complaint, and intends to defend vigorously any and all such allegations.

The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business, including, but not limited to, examinations by the Internal Revenue Service.

The Company’s management does not expect that the outcome in any of its currently ongoing legal proceedings or the outcome of any proposed adjustments presented to date by the Internal Revenue Service, individually or collectively, will have a material adverse effect on the Company’s financial condition, results of operations, or cash flow.

In January 2008, the Company’s Board of Directors authorized the repurchase of up to $500 million of the Company’s common stock. Through February 15, 2008, the Company had repurchased 4.4 million shares for a total of approximately $54 million, at which time repurchases under the program were suspended. On August 5, 2011, the Company’s Board of Directors authorized the Company to resume a share repurchase program and approved the Company’s repurchase, on a discretionary basis, of a total of up to $500 million of the Company’s common stock following such authorization. On May 16, 2012, the Company’s Board of Directors increased the previous share repurchase authorization by an additional $500 million. On May 15, 2013, the Company's Board of Directors further increased the previous share repurchase authorization by an additional $500 million to a total of $1.5 billion and, in a privately negotiated transaction, the Company entered into the ASR Program with a third party financial institution to buy $250 million of its common shares utilizing cash on hand. Repurchases are made in accordance with applicable securities laws in open market, private, or accelerated repurchase transactions from time to time, depending on market conditions, and may be discontinued at any time.

(2)

During May 2013, under the ASR Program, the Company paid $250 million and received an initial delivery of 17,882,690 shares. The Company also made a $500 thousand additional payment to the third party financial institution under the terms of the agreement governing the ASR Program. Upon completion of the ASR Program in June 2013, the Company received 157,907 additional shares of its common stock. The calculation of average price paid per share does not include amounts attributable to the shares delivered upon completion of the ASR Program or to the $500 thousand additional payment made by the Company. In total, the average purchase price per share for the 18,040,597 shares repurchased under the ASR Program, upon completion of the ASR Program in June 2013, was $13.89.
