Accounting Policies [Abstract] | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation Southwest Airlines Co. (the “Company”) operates Southwest Airlines, a major domestic airline. The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries, which include AirTran Holdings, LLC. The Company owns all of the outstanding equity of AirTran Holdings, Inc. (“AirTran Holdings”), the former parent company of AirTran Airways, Inc. (“AirTran Airways”). Throughout these Notes, the Company makes reference to AirTran, which is meant to be inclusive of AirTran Holdings, LLC, the successor to AirTran Holdings, and its subsidiaries, including among others, AirTran Airways. AirTran's final passenger service was on December 28, 2014. All integration costs were incurred in periods prior to 2016. The accompanying Consolidated Financial Statements include the results of operations and cash flows for all periods presented and all significant inter-entity balances and transactions have been eliminated. The preparation of financial statements in conformity with generally accepted accounting principles in the United States (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. Cash and Cash Equivalents Cash in excess of that necessary for operating requirements is invested in short-term, highly liquid, income-producing investments. Investments with original maturities of three months or less when purchased are classified as cash and cash equivalents, which primarily consist of certificates of deposit, money market funds, and investment grade commercial paper issued by major corporations and financial institutions. Cash and cash equivalents are stated at cost, which approximates fair value. As of December 31, 2016 , $301 million in net cash collateral deposits were provided by the Company to its fuel hedge counterparties and no cash collateral deposits were held by or provided by the Company to its interest rate hedge counterparties. As of December 31, 2015 , $835 million in cash collateral deposits were provided by the Company to its fuel hedge counterparties and no cash collateral deposits were held by or provided by the Company to its interest rate hedge counterparties. Cash collateral amounts provided or held associated with fuel and interest rate derivative instruments are not restricted in any way and earn interest income at an agreed upon rate that approximates the rates earned on short-term securities issued by the U.S. Government. Depending on the fair value of the Company’s fuel and interest rate derivative instruments, the amounts of collateral deposits held or provided at any point in time can fluctuate significantly. See Note 10 for further information on these collateral deposits and fuel derivative instruments. Short-term and Noncurrent Investments Short-term investments consist of investments with original maturities of greater than three months but less than twelve months when purchased. These are primarily short-term securities issued by the U.S. Government and certificates of deposit issued by domestic banks. All of these investments are classified as available-for-sale securities and are stated at fair value, which approximates cost. For all short-term investments, at each reset period or upon reinvestment, the Company accounts for the transaction as Proceeds from sales of short-term investments for the security relinquished, and Purchases of short-investments for the security purchased, in the accompanying Consolidated Statement of Cash Flows. Unrealized gains and losses, net of tax, if any, are recognized in Accumulated other comprehensive income (loss) (“AOCI”) in the accompanying Consolidated Balance Sheet. Realized net gains and losses on specific investments, if any, are reflected in Interest income in the accompanying Consolidated Statement of Income. Both unrealized and realized gains and/or losses associated with investments were immaterial for all years presented. Noncurrent investments consist of investments with maturities of greater than twelve months. Noncurrent investments are included as a component of Other assets in the Consolidated Balance Sheet. Accounts and Other Receivables Accounts and other receivables are carried at cost. They primarily consist of amounts due from credit card companies associated with sales of tickets for future travel, and amounts due from business partners in the Company’s frequent flyer program. The allowance for doubtful accounts was immaterial at December 31, 2016 and 2015 . In addition, the provision for doubtful accounts and write-offs for 2016 , 2015 , and 2014 were each immaterial. Inventories Inventories primarily consist of aircraft fuel, flight equipment expendable parts, materials, and supplies. All of these items are carried at average cost, less an allowance for obsolescence. These items are generally charged to expense when issued for use. The reserve for obsolescence was $57 million and $47 million at December 31, 2016 , and 2015 , respectively. In addition, the Company’s provision for obsolescence and write-offs for 2016 , 2015 , and 2014 were each immaterial. Property and Equipment Property and equipment is stated at cost. Capital expenditures includes payments made for aircraft, other flight equipment, purchase deposits related to future aircraft deliveries, and ground and other property and equipment. Depreciation is provided by the straight-line method to estimated residual values over periods generally ranging from 23 to 25 years for flight equipment, 5 to 30 years for ground property and equipment, and 25 to 30 years, or the expected term of the Company's lease if shorter, for Assets constructed for others, once the asset is placed in service. Residual values estimated for aircraft generally range from 2 to 20 percent , for ground property and equipment generally range from 0 to 10 percent , and for Assets constructed for others range from 17 to 25 percent . Property under capital leases and related obligations are initially recorded at an amount equal to the present value of future minimum lease payments computed on the basis of the Company’s incremental borrowing rate or, when known, the interest rate implicit in the lease. Amortization of property under capital leases is on a straight-line basis over the lease term and is included in Depreciation and amortization expense. Leasehold improvements generally are amortized on a straight-line basis over the shorter of the estimated useful life of the improvement or the remaining term of the lease. Assets constructed for others primarily consists of airport improvement projects, once placed into service, in which the Company is considered the accounting owner of the facilities. See Note 4 for further information. During first quarter 2016, the Company made the decision to further simplify its operations and accelerate the retirement of its less-efficient Classic fleet to no later than third quarter 2017, versus the original scheduled retirement of this fleet that had extended out to 2021. This change in retirement dates is considered a change in estimate and has been accounted for on a prospective basis as of the dates the decisions were finalized. Therefore, the Company has recorded and will record accelerated depreciation expense over the remainder of the useful lives for each Classic aircraft and related parts. See Note 7 for further information regarding the Company's aircraft fleet. (in millions, except per share amounts) Year ended December 31, 2016 Depreciation and amortization expense $ 123 Net income * $ (66 ) Net income per basic share $ (0.11 ) Net income per diluted share $ (0.10 ) * net of profitsharing benefit The estimated impact to Depreciation and amortization expense from this change in assumption for 2017 is an approximate increase of $21 million . The Company evaluates its long-lived assets used in operations for impairment when events and circumstances indicate that the undiscounted cash flows to be generated by that asset are less than the carrying amounts of the asset and may not be recoverable. Factors that would indicate potential impairment include, but are not limited to, significant decreases in the market value of the long-lived asset(s), a significant change in the long-lived asset’s physical condition, and operating or cash flow losses associated with the use of the long-lived asset. If an asset is deemed to be impaired, an impairment loss is recorded for the excess of the asset book value in relation to its estimated fair value. Aircraft and Engine Maintenance The cost of scheduled inspections and repairs and routine maintenance costs for all aircraft and engines are charged to Maintenance materials and repairs expense as incurred. The Company also has “power-by-the-hour” agreements related to certain of its aircraft engines with external service providers. Under these agreements, which the Company has determined effectively transfer the risk and create an obligation associated with the maintenance on such engines to the counterparty, expense is recorded commensurate with each hour flown on an engine. In situations where the payments to the counterparty do not sufficiently match the level of services received during the period, expense is recorded on a straight-line basis over the term of the agreement based on the Company's best estimate of expected future aircraft utilization. For its engine maintenance contracts that do not transfer risk to the service provider, the Company records expense on a time and materials basis when an engine repair event takes place. Modifications that significantly enhance the operating performance or extend the useful lives of aircraft or engines are capitalized and amortized over the remaining life of the asset. Goodwill and Intangible Assets The Company applies a fair value based impairment test to the carrying value of goodwill and indefinite-lived intangible assets annually on October 1st, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred. The Company assesses the value of goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Under a qualitative approach, the Company considers various market factors, including applicable key assumptions listed below. These factors are analyzed to determine if events and circumstances could reasonably have affected the fair value of goodwill and indefinite-lived intangible assets. If the Company determines that it is more likely than not that an indefinite-lived intangible asset is impaired, the quantitative approach is used to assess the asset’s implied fair value and the amount of the impairment. Under a quantitative approach, the implied fair value of the Company's identifiable assets and liabilities is calculated based on key assumptions. If the Company assets' carrying value exceeds the fair value calculated using the quantitative approach, an impairment charge is recorded for the difference in fair value and carrying value. The following table is a summary of the Company’s intangible assets, which are included as a component of Other assets in the Company's Consolidated Balance Sheet, as of December 31, 2016 and 2015 : Year ended December 31, 2016 Year ended December 31, 2015 (in millions) Weighted-average useful life (in years) Gross carrying amount Accumulated amortization Gross carrying amount Accumulated Amortization Customer relationships/marketing agreements 9 $ 38 $ 32 $ 38 $ 30 Trademarks/trade names 6 36 36 36 34 Owned domestic slots (a) Indefinite 295 — 303 n/a Leased domestic slots (a) — — — 17 3 Gate leasehold rights (b) 15 180 55 180 43 Total 13 $ 549 $ 123 $ 574 $ 110 (a) The Company recorded a $21 million impairment associated with owned and leased slots at Newark Liberty International Airport as a result of the FAA announcement, in April 2016, that this airport was being changed to a Level 2 schedule-facilitated airport from its previous designation as Level 3. (b) Intangible assets primarily consist of acquired leasehold rights to certain airport owned gates, takeoff and landing slots (a “slot” is the right of an air carrier, pursuant to regulations of the FAA, to operate a takeoff or landing at a specific time at certain airports) at certain domestic slot-controlled airports, and certain intangible assets acquired. The aggregate amortization expense for 2016 , 2015 , and 2014 was $17 million , $19 million , and $13 million , respectively. Estimated aggregate amortization expense for the five succeeding years and thereafter is as follows: 2017 – $13 million , 2018 – $13 million , 2019 – $13 million , 2020 – $12 million , 2021 – $12 million , and thereafter – $68 million . Revenue Recognition Tickets sold are initially deferred as Air traffic liability. Passenger revenue is recognized when transportation is provided. Air traffic liability primarily represents tickets sold for future travel dates and funds that are past flight date and remain unused. The majority of the Company’s tickets sold are nonrefundable. Refundable tickets that are sold but not flown on the travel date can be reused for another flight, up to a year from the date of sale, or refunded. A small percentage of tickets (or partial tickets) expire unused. The Company estimates the amount of tickets that expire unused and recognizes such amounts in Passenger revenue using the redemption method based on the scheduled flight date. Southwest has a No Show policy that applies to certain nonrefundable fares that are not canceled or changed by a Customer at least ten minutes prior to a flight's scheduled departure. Based on the Company's revenue recognition policy, revenue is recorded at the flight date for a Customer who does not change his/her itinerary and loses his/her funds. Amounts collected from passengers for ancillary service fees are generally recognized as Other revenue when the service is provided, which is typically the flight date. The Company's policy is to record revenue for the estimated spoilage of tickets (including partial tickets) once the flight date has passed, under the redemption method. Initial spoilage estimates are routinely adjusted and ultimately finalized once the tickets expire, which is typically twelve months after the original purchase date. Spoilage estimates are based on the Customers' historical travel behavior as well as assumptions about the Customers' future travel behavior. Assumptions used to generate spoilage estimates can be impacted by several factors including, but not limited to: fare increases, fare sales, changes to the Company's ticketing policies, changes to the Company’s refund, exchange and unused funds policies, and economic factors. The Company is also required to collect certain taxes and fees from Customers on behalf of government agencies and remit these back to the applicable governmental entity on a periodic basis. These taxes and fees include foreign and U.S. federal transportation taxes, federal security charges, and airport passenger facility charges. These items are collected from Customers at the time they purchase their tickets, but are not included in Passenger revenue. The Company records a liability upon collection from the Customer and relieves the liability when payments are remitted to the applicable governmental agency. Frequent Flyer Program The Company records a liability for the estimated incremental cost of providing free travel under its frequent flyer program for all amounts earned from flight activity that are expected to be redeemed for future travel. The estimated incremental cost includes direct passenger costs such as fuel, food, and other operational costs, but does not include any contribution to fixed overhead costs or profit. Southwest also sells frequent flyer points and related services to companies participating in its frequent flyer program. Historically, until July 1, 2015, funds received from the sale of points associated with these agreements were accounted for under the residual method. Under this method, the Company estimated the portion of the amounts received from the sale of frequent flyer points that related to free travel and these amounts were deferred and recognized as Passenger revenue when the ultimate free travel awards were flown. Effective July 1, 2015, the Company entered into an amended co-branded credit card agreement ("Agreement") with Chase Bank USA, N.A. (“Chase”), through which the Company sells loyalty points and other items to Chase. This material modification triggered an accounting change under ASU 2009-13, which was recorded on a prospective basis. The impact of the accounting change is that the Company estimated the selling prices and volumes over the term of the Agreement in order to determine the allocation of proceeds to each of the deliverables (travel points to be awarded; use of the Southwest Airlines’ brand and access to Rapid Reward Member lists; advertising elements; and the Company’s resource team). The Company records passenger revenue related to air transportation and certificates for discounted companion travel when the transportation is delivered. The other elements are recognized as Other - net revenue when earned. The Company followed the transition approach of ASU 2009-13, which required that the Company adjust the existing deferred revenue balance, classified within Air traffic liability, to reflect the value, on a relative selling price basis, of any undelivered element remaining at the date of contract modification. The relative selling price of the undelivered element (air transportation) was lower than the rate at which it had been deferred under the residual method, and the Company recorded a one-time, non-cash adjustment to decrease frequent flyer deferred revenue and increase revenue through the recording of a Special revenue adjustment of $172 million in 2015. The estimated impacts on revenue and earnings associated with the Agreement and this change in accounting principle recognized subsequent to the effective date of July 1, 2015, are as follows: (in millions, except per share amounts) Year ended December 31, 2016 Year ended December 31, 2015 Passenger revenue $ (250 ) $ (89 ) Special revenue adjustment — 172 Other revenue 794 344 Operating revenues $ 544 $ 427 Net income $ 293 $ 227 Net income per basic share $ 0.47 $ 0.34 Net income per diluted share $ 0.46 $ 0.34 For all points sold to business partners that are expected to expire unused, the Company recognizes spoilage in accordance with the redemption method. The Company’s consolidated liability associated with the sale of frequent flyer points, was approximately $1.4 billion and $1.3 billion as of December 31, 2016 , and 2015 , respectively, which is classified within Air traffic liability. During fourth quarter 2014, the Company obtained sufficient historical behavioral data to develop a predictive statistical model to analyze the amount of spoilage expected for points sold to business partners, which indicated an increase in the expected spoilage rate. This change in estimate was recorded on a prospective basis, as of October 1, 2014. The impacts on revenue and earnings were as follows: (in millions, except per share amounts) Year ended December 31, 2015 Year ended December 31, 2014 Passenger revenue $ 115 $ 55 Net income $ 61 $ 29 Net income per basic share $ 0.09 $ 0.04 Net income per diluted share $ 0.09 $ 0.04 The Company continues to evaluate annually in October, but these analyses have not resulted in a material adjustment. Advertising Advertising costs are charged to expense as incurred. Advertising and promotions expense for the years ended December 31, 2016 , 2015 , and 2014 was $232 million , $218 million , and $207 million , respectively, and is included as a component of Other operating expense in the accompanying Consolidated Statement of Income. Share-based Employee Compensation The Company has share-based compensation plans covering certain Employees, including a plan that also covers the Company’s Board of Directors. The Company accounts for share-based compensation based on its grant date fair value. See Note 9 for further information. Financial Derivative Instruments The Company accounts for financial derivative instruments at fair value and applies hedge accounting rules where appropriate. The Company utilizes various derivative instruments, including jet fuel, crude oil, unleaded gasoline, and heating oil-based derivatives, to attempt to reduce the risk of its exposure to jet fuel price increases. These instruments consist primarily of purchased call options, collar structures, call spreads, put spreads, and fixed price swap agreements, and upon proper qualification are accounted for as cash-flow hedges. The Company also has interest rate swap agreements to convert a portion of its fixed-rate debt to floating rates and has swap agreements that convert certain floating-rate debt to a fixed-rate. These interest rate hedges are appropriately designated as either fair value hedges or as cash flow hedges. Since the majority of the Company’s financial derivative instruments are not traded on a market exchange, the Company estimates their fair values. Depending on the type of instrument, the values are determined by the use of present value methods or option value models with assumptions about commodity prices based on those observed in underlying markets. Also, since there is not a reliable forward market for jet fuel, the Company must estimate the future prices of jet fuel in order to measure the effectiveness of the hedging instruments in offsetting changes to those prices. Forward jet fuel prices are estimated through utilization of a statistical-based regression equation with data from market forward prices of like commodities. This equation is then adjusted for certain items, such as transportation costs, that are stated in the Company’s fuel purchasing contracts with its vendors. For the effective portion of settled fuel hedges, the Company records the associated gains or losses as a component of Fuel and oil expense in the Consolidated Statement of Income. For amounts representing ineffectiveness, as defined, or changes in fair value of derivative instruments for which hedge accounting is not applied, the Company records any gains or losses as a component of Other (gains) losses, net, in the Consolidated Statement of Income. Amounts that are paid or received in connection with the purchase or sale of financial derivative instruments (i.e., premium costs of option contracts) are classified as a component of Other (gains) losses, net, in the Consolidated Statement of Income in the period in which the instrument settles or expires. All cash flows associated with purchasing and selling derivatives are classified as operating cash flows in the Consolidated Statement of Cash Flows, within Changes in certain assets and liabilities. See Note 10 for further information on hedge accounting and financial derivative instruments. The Company classifies its cash collateral provided to or held from counterparties in a “net” presentation on the Consolidated Balance Sheet against the fair value of the derivative positions with those counterparties. See Note 10 for further information. Software Capitalization The Company capitalizes certain internal and external costs related to the acquisition and development of internal use software during the application development stages of projects. The Company amortizes these costs using the straight-line method over the estimated useful life of the software, which is typically five to fifteen years. Costs incurred during the preliminary project or the post-implementation/operation stages of the project are expensed as incurred. Capitalized computer software, included as a component of Ground property and equipment in the accompanying Consolidated Balance Sheet, net of accumulated depreciation, was $544 million and $378 million at December 31, 2016 , and 2015 , respectively. Computer software depreciation expense was $111 million , $106 million , and $122 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively, and is included as a component of Depreciation and amortization expense in the accompanying Consolidated Statement of Income. The Company evaluates internal use software for impairment on a quarterly basis; if it is determined the value of an asset was not recoverable or it qualifies for impairment, a charge would be recorded to write down the software to the lower of its carrying value or fair value. The Company had no significant impairments during 2016 , 2015 , or 2014 . Income Taxes The Company accounts for deferred income taxes utilizing an asset and liability method, whereby deferred tax assets and liabilities are recognized based on the tax effect of temporary differences between the financial statements and the tax basis of assets and liabilities, as measured by current enacted tax rates. The Company also evaluates the need for a valuation allowance to reduce deferred tax assets to estimated recoverable amounts. See "Basis of Presentation" for further information on current presentation of deferred income taxes. The Company’s policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of income before income taxes. Penalties are recorded in Other (gains) losses, net, and interest paid or received is recorded in Interest expense or Interest income, respectively, in the Consolidated Statement of Income. Amounts recorded for penalties and interest related to uncertain tax positions were immaterial for all years presented. See Note 14 for further information. Concentration Risk Approximately 83 percent of the Company’s full-time equivalent Employees are unionized and are covered by collective-bargaining agreements. A small percentage of the Company's unionized Employees, including its Mechanics, Material Specialists, and Facilities Maintenance Technicians, are in discussions on labor agreements. These Employee groups represent approximately five percent of the Company’s full-time equivalent Employees as of December 31, 2016. The Company attempts to minimize its concentration risk with regards to its cash, cash equivalents, and its investment portfolio. This is accomplished by diversifying and limiting amounts among different counterparties, the type of investment, and the amount invested in any individual security or money market fund. To manage risk associated with financial derivative instruments held, the Company selects and will periodically review counterparties based on credit ratings, limits its exposure to a single counterparty, and monitors the market position of the program and its relative market position with each counterparty. The Company also has agreements with counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount or credit ratings fall below certain levels. Collateral deposits provided to or held from counterparties serve to decrease, but not totally eliminate, the credit risk associated with the Company’s hedging program. See Note 10 for further information. As of December 31, 2016 , the Company operated an all-Boeing fleet, all of which are variations of the Boeing 737. If the Company were unable to acquire additional aircraft or associated aircraft parts from Boeing, or Boeing were unable or unwilling to make timely deliveries of aircraft or to provide adequate support for its products, the Company’s operations would be materially adversely impacted. In addition, the Company would be materially adversely impacted in the event of a mechanical or regulatory issue associated with the Boeing 737 aircraft type, whether as a result of downtime for part or all of the Company’s fleet, increased maintenance costs, or because of a negative perception by the flying public. The Company is also dependent on sole suppliers for aircraft engines and certain other aircraft parts and would, therefore, also be materially adversely impacted in the event of the unavailability of, or a mechanical or regulatory issue associated with, engines and other parts. The Company has historically entered into agreements with some of its co-brand, payment, and loyalty partners that contain exclusivity aspects which place certain confidential restrictions on the Company from entering into certain arrangements with other payment and loyalty partners. These arrangements generally extend for the terms of the agreements, none of which currently extend beyond May 2022 . The Company believes the financial benefits generated by the exclusivity aspects of these arrangements outweigh the risks involved with such agreements. |

Accounting Changes and Error Corrections [Abstract] | |
NEW ACCOUNTING PRONOUNCEMENTS | NEW ACCOUNTING PRONOUNCEMENTS AND ACCOUNTING CHANGES On August 26, 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-15, Statement of Cash Flows. The standard is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the new guidance, but does not expect it to have a significant impact on its financial statement presentation or results. On June 16, 2016, the FASB issued ASU No. 2016-13, Accounting for Credit Losses. The new standard requires the use of an “expected loss” model on certain types of financial instruments. The standard also amends the impairment model for available-for-sale debt securities and requires estimated credit losses to be recorded as allowances instead of reductions to amortized cost of the securities. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. The Company is evaluating the new guidance, but does not expect it to have a significant impact on its financial statement presentation or results. On March 30, 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. The standard is part of the FASB effort to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company early adopted this standard during the three months ended June 30, 2016, with an effective date as of January 1, 2016. The prospective method of adoption of this standard resulted in the recognition of $7 million of excess tax benefits to the Company's income tax provision for the year ended December 31, 2016 . On February 25, 2016, the FASB issued ASU No. 2016-02, Leases. The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. The Company believes the most significant impact of this ASU on its accounting will be the presentation of operating leases with durations greater than twelve months, with certain exceptions, on the balance sheet. A portion of the Company's aircraft fleet is on operating lease, and it has contractual lease agreements associated with the majority of space from which it operates at the airports it serves. See Note 7 for more information on the Company's lease arrangements. The Company has formed a project team to evaluate and implement the standard and plans to provide additional information about its expected financial impact at a future date. On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. Following the FASB's finalization of a one year deferral of this standard, the ASU is now effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2017, with early adoption permitted for fiscal years, and interim periods within those years, beginning on or after December 15, 2016. The Company has formed a project team to evaluate and implement the standard, and currently believes the most significant impact of this ASU on its accounting will be the elimination of the incremental cost method for frequent flyer accounting, which will require the Company to re-value its liabilities associated with Customer flight points with a relative fair value approach, resulting in a significant increase in the liabilities. The Company's liabilities associated with these flight points was $63 million at December 31, 2016, and the Company currently estimates that applying a relative fair value would increase the liabilities by approximately twenty times that value. The adoption of the new standard is also expected to result in different income statement classification for certain types of revenues, such as ancillary revenues, which are currently classified as Other revenues. The Company currently anticipates utilizing the full retrospective method of adoption allowed by the standard, in order to provide for comparative results in all periods presented, and plans to adopt the standard as of January 1, 2018. The Company is continuing to evaluate the new guidance both internally and through its participation in an industry working group, and plans to provide additional information at a future date. |

Commitments and Contingencies Disclosure [Abstract] | |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Commitments The Company has contractual obligations and commitments primarily with regard to future purchases of aircraft, repayment of debt (see Note 6 ), and lease arrangements (see Note 7 ). During the year ended December 31, 2016 , the Company purchased 38 new 737-800 aircraft from Boeing and acquired 23 used 737-700 aircraft from third parties under capital leases. In addition, the Company retired from service 42 of its older aircraft ( 31 737-300 and 11 737-500). As of December 31, 2016 , the Company had firm deliveries and options for Boeing 737-700, 737-800, 737-7, and 737-8 aircraft as follows: The Boeing Company -800 Firm Orders -800 Options -7 -8 -8 Additional -700s Total 2017 39 — — 14 — 14 67 2018 21 9 — 13 — 4 47 2019 — — 15 — 5 — 20 2020 — — 14 — 8 — 22 2021 — — 1 13 18 — 32 2022 — — — 15 19 — 34 2023 — — — 34 23 — 57 2024 — — — 41 23 — 64 2025 — — — 40 36 — 76 2026 — — — — 36 — 36 2027 — — — — 23 — 23 60 9 (a) 30 170 (b) 191 18 (c) 478 (a) Includes two -800 options exercised in January 2017. (b) The Company has flexibility to substitute 737-7 in lieu of 737-8 firm orders beginning in 2019 . (c) To be acquired in leases from various third parties. The Company's capital commitments associated with the firm orders and additional aircraft in the above aircraft table are as follows: $1.1 billion in 2017 , $893 million in 2018 , $614 million in 2019 , $821 million in 2020 , $952 million in 2021 , and $5.1 billion thereafter. Fort Lauderdale-Hollywood International Airport In December 2013 , the Company entered into an agreement with Broward County, Florida, which owns and operates Fort Lauderdale-Hollywood International Airport, to oversee and manage the design and construction of the airport's Terminal 1 Modernization Project. Pursuant to an addendum entered into during 2016, the cost of the project is not to exceed $333 million . In addition to significant improvements to the existing Terminal 1, the project includes the design and construction of a new five-gate Concourse A with an international processing facility. Funding for the project has come directly from Broward County aviation sources, but flows through the Company in its capacity as manager of the project. Major construction on the project began during third quarter 2015 and is estimated to be substantially completed by mid-2017. The Company has determined that due to its agreed upon role in overseeing and managing the project, it is considered the owner of the project for accounting purposes. As such, during construction the Company records expenditures as Assets constructed for others in the Consolidated Balance Sheet, along with a corresponding outflow within Assets constructed for others in the Consolidated Statement of Cash Flows, and an increase to Construction obligation (with a corresponding cash inflow from Financing activities in the Consolidated Statement of Cash Flows) as reimbursements are received from Broward County. As of December 31, 2016 , the Company had recorded construction costs related to the project of $132 million . Houston William P. Hobby Airport The Company entered into a Memorandum of Agreement (“MOA”) with the City of Houston (“City”), effective June 2012 , to expand the existing Houston Hobby airport facility. As provided in the MOA, the Company and the City entered into an Airport Use and Lease Agreement (“Lease”) to control the execution of this expansion and the financial terms thereof. Per the MOA and Lease, this project provided a new five-gate international terminal with international passenger processing facilities, expansion of the security checkpoint, and upgrades to the Southwest Airlines ticket counter area. Construction was effectively completed in October 2015, at which time the Company began operating from the new facility. The project's final cost was approximately $150 million , of which $22 million was considered proprietary and thus not classified as Assets constructed for others. The Company provided the funding for, as well as management over, the project. In return, the capital cost portion of the rent the Company pays for the international facility is waived from the initial occupancy until the expiration of the Lease. However, the City has the option at any time during the term of the Lease to reimburse the Company's investment at the then-unamortized cost of the facility. This purchase would trigger payment of the previously waived capital cost component of rents owed the City. Additionally, a small portion of the project qualified for rental credits that have been utilized against a portion of the Company’s 2016 lease payments at the airport. As a result of its significant involvement in the Houston Hobby project, the Company determined that it is the owner of the facility for accounting purposes. As such, during construction, the Company recorded expenditures as Assets constructed for others in the Consolidated Balance Sheet, along with a corresponding outflow within Assets constructed for others, in the Consolidated Statement of Cash Flows. Los Angeles International Airport In March 2013, the Company executed a lease agreement with Los Angeles World Airports (“LAWA”), which owns and operates Los Angeles International Airport ("LAX"). Under the lease agreement, which was amended in June 2014, the Company is overseeing and managing the design, development, financing, construction, and commissioning of the airport's Terminal 1 Modernization Project (the “Project”) at a cost not to exceed $526 million . The Project is being funded primarily using the Regional Airports Improvement Corporation ("RAIC"), which is a quasi-governmental special purpose entity that acts as a conduit borrower under a syndicated credit facility provided by a group of lenders. Loans made under the credit facility are being used to fund the development of the Project, and the outstanding loans will be repaid with the proceeds of LAWA’s payments to purchase completed Project phases. The Company has guaranteed the obligations of the RAIC under the credit facility. Construction on the Project began during 2014 and is estimated to be completed during 2018. The Company has determined that due to its agreed upon role in overseeing and managing the Project, it is considered the owner of the Project for accounting purposes. LAWA will reimburse the Company (through the RAIC credit facility) for the non-proprietary renovations, while proprietary renovations will not be reimbursed. As a result, the $344 million of costs incurred as of December 31, 2016 , to fund the Project are included within Assets constructed for others and all amounts that have been or will be reimbursed will be included within Construction obligation on the accompanying Consolidated Balance Sheet. Dallas Love Field During 2008 , the City of Dallas approved the Love Field Modernization Program (“LFMP”), a project to reconstruct Dallas Love Field with modern, convenient air travel facilities. Pursuant to a Program Development Agreement 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 of Dallas to act on the City of Dallas' behalf to facilitate the development of the LFMP), the Company managed this project. Major construction was effectively completed by December 31, 2014. This project consisted 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. Although the City of Dallas received commitments from various sources that are helping to fund portions of the LFMP project, including the FAA, the Transportation Security Administration, and the City of Dallas' Aviation Fund, the majority of the funds used were from the issuance of bonds. The Company guaranteed principal and interest payments on $456 million of such bonds issued by the LFAMC. As of December 31, 2016 , $432 million of principal remained outstanding. In conjunction with the Company's significant presence at Dallas Love Field, the Company agreed to manage the majority of the LFMP project. Based on the pertinent factors in place at the time the agreement was made, the Company utilized the accounting guidance provided for lessees involved in asset construction. As of December 31, 2016 , the Company had recorded LFMP construction costs of $538 million within Assets constructed for others and had recorded a liability of $522 million within Construction obligation in its 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. In addition, upon the effective completion of construction, the Company noted the project assets did not meet the qualifications for sale and leaseback accounting due to the Company's continuing involvement with the facility, as defined; therefore, for financial reporting purposes, these assets will remain on the Company's books until the bonds issued by the City of Dallas are repaid. The corresponding LFMP liabilities are being reduced primarily through the Company's airport rental payments to the City of Dallas as the construction costs of this project are passed through to the Company via recurring airport rates and charges. A portion of these payments are reflected as Repayment of construction obligation in the Consolidated Statement of Cash Flows. The imputed interest rate associated with Construction obligation was nominal for 2015 and 2016. During 2015, the City of Dallas issued additional bonds for the construction of a new parking garage at Dallas Love Field. The Company has not guaranteed the principal or interest payments on these bonds, but remains the accounting owner of this project. As of December 31, 2016 , the Company recorded LFMP parking construction expenditures of $80 million with Assets constructed for others with a corresponding increase to Construction obligation on the accompanying Consolidated Balance Sheet. 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 Internal Revenue Service ("IRS"). The Company's management does not expect that the outcome of any of its currently ongoing legal proceedings or the outcome of any adjustments presented by the IRS, individually or collectively, will have a material adverse effect on the Company's financial condition, results of operations, or cash flow. |

Each note is secured by a first mortgage on the aircraft to which it relates. The notes bear interest at a floating rate per annum equal to a margin plus the three or six-month LIBOR in effect at the commencement of each semi-annual or three-month period, as applicable. As of December 31, 2016 , the weighted average interest rate was 2.40 percent . Principal and interest under the notes are payable semi-annually or every three months as applicable. As of December 31, 2016 , the remaining debt outstanding may be prepaid without penalty under all aircraft loans provided under such facilities. The remaining notes mature in years 2017 to 2020 . As discussed further in Note 10 , a portion of the above floating-rate debt has been effectively converted to a fixed rate via interest rate swap agreements which expire as the underlying notes mature. As of December 31, 2016 , two Boeing 737 aircraft were financed under a fixed-rate facility. Each note is secured by a first mortgage on the aircraft to which it relates. As of December 31, 2016 , the weighted average interest rate was 7.03 percent . Payments of principal and interest under the notes are due semi-annually. The remaining notes mature in years 2017 to 2018 . In October 2009 , AirTran Holdings completed a public offering of $115 million of convertible senior notes due November 1, 2016. Such notes bore interest at 5.25 percent payable semi-annually, in arrears, on May 1 and November 1 . As a result of the acquisition and subsequent dividends declared by the Company, the convertible senior notes were convertible into AirTran conversion units of 168.6576 per $1,000 in principal amount of such notes. Based on the terms of the merger agreement, the holders of these notes could receive shares of the Company’s common stock at a conversion rate of 54.5143 shares and $615.16 in cash per $1,000 in principal amount of such notes. During 2016, all the bonds matured, the majority of which had been converted prior to the maturity date, with approximately 6 million shares issued and cash paid of approximately $68 million . Other Company Long-Term Debt During November 2016, the Company issued $300 million senior unsecured notes due 2026 . The notes bear interest at 3.00 percent . Interest is payable semi-annually in arrears on May 15 and November 15, beginning in 2017. During October 2016, the Company entered into a term loan agreement providing for loans to the Company aggregating up to $215 million , to be secured by mortgages on seven of the Company's 737-800 aircraft. The Company has borrowed the full $215 million and secured this loan with the requisite seven aircraft mortgages. The loan matures on October 31, 2026, and is repayable via semi-annual installments of principal that begin April 30, 2018. The loan bears interest at the LIBO Rate (as defined in the term loan agreement) plus 1.10 percent , which equates to an initial rate of 2.36 percent , and interest is payable semi-annually in installments that begin April 30, 2017. During third quarter 2016, the Company entered into term loan agreements to purchase the equity interest in four aircraft that were previously classified as operating leases, for a total of $20 million . As of December 31, 2016 , the weighted average interest rate for the four term loan agreements was 7.94 percent . Payments of principal and interest under the loans are due semi-annually. The loans mature in years 2018 to 2021 . During November 2015, the Company issued $500 million senior unsecured notes due 2020 . The notes bear interest at 2.65 percent , payable semi-annually in arrears on May 5 and November 5. Concurrently, the Company entered into a fixed-to-floating interest rate swap to convert the interest on these unsecured notes to a floating rate until their maturity. See Note 10 for further information on the interest-rate swap agreement. During November 2014 , the Company issued $300 million senior unsecured notes due 2019 . The notes bear interest at 2.75 percent , payable semi-annually in arrears on May 6 and November 6 . Concurrently, the Company entered into a fixed-to-floating interest rate swap to convert the interest on these unsecured notes to a floating rate until their maturity. See Note 10 for further information on the interest-rate swap agreement. On July 1, 2009 , the Company entered into a term loan agreement providing for loans to the Company aggregating up to $124 million , to be secured by mortgages on five of the Company’s 737-700 aircraft. The Company has borrowed the full $124 million and secured this loan with the requisite five aircraft mortgages. The loan matures on July 1, 2019 , and is repayable semi-annually in installments of principal that began January 1, 2010 . The loan bears interest at a fixed rate of 4.84 percent , and interest is payable semi-annually, which payments began on January 1, 2010 . In September 2015 , the Company prepaid $24 million on the loan agreement, which in turn released one of the encumbered aircraft. As such, the remaining four aircraft related to this transaction are still encumbered as of December 31, 2016 . On April 29, 2009 , the Company entered into a term loan agreement providing for loans to the Company aggregating up to $332 million , to be secured by mortgages on 14 of the Company’s 737-700 aircraft. The Company borrowed the full $332 million and secured the loan with the requisite 14 aircraft mortgages. The loan matures on May 6, 2019 , and is being repaid via quarterly installments of principal that began August 6, 2009 . The loan bears interest at the LIBO Rate (as defined in the term loan agreement) plus 3.30 percent , and interest is payable quarterly, which payments began on August 6, 2009 . Pursuant to the terms of the term loan agreement, the Company entered into an interest rate swap agreement to convert the variable rate on the term loan to a fixed 6.315 percent until maturity. On May 6, 2008 , the Company entered into a term loan agreement providing for loans to the Company aggregating up to $600 million , to be secured by first-lien mortgages on 21 of the Company’s 737-700 aircraft. On May 9, 2008, the Company borrowed the full $600 million and secured these loans with the requisite 21 aircraft mortgages. The loans mature on May 9, 2020 , and are repayable quarterly in installments of principal, with the first payment made on August 9, 2008. The loans bear interest at the LIBO Rate (as defined in the term loan agreement) plus 0.95 percent , and interest is payable quarterly. Pursuant to the terms of the term loan agreement, the Company entered into an interest rate swap agreement to convert the variable rate on the term loan to a fixed 5.223 percent until maturity. On October 3, 2007 , grantor trusts established by the Company issued $500 million Pass Through Certificates consisting of $412 million 6.15 percent Series A certificates and $88 million 6.65 percent Series B certificates. A separate trust was established for each class of certificates. The trusts used the proceeds from the sale of certificates to acquire equipment notes in the same amounts, which were issued by the Company on a full recourse basis. Payments on the equipment notes held in each trust will be passed through to the holders of certificates of such trust. The equipment notes were issued for each of 16 Boeing 737-700 aircraft owned by the Company and are secured by a mortgage on each aircraft. Interest on the equipment notes held for the certificates is payable semi-annually, with the first payment made on February 1, 2008 . Also beginning February 1, 2008, principal payments on the equipment notes held for both series of certificates are due semi-annually until the balance of the certificates mature on August 1, 2022 . Prior to their issuance, the Company also entered into swap agreements to hedge the variability in interest rates on the Pass Through Certificates. The swap agreements were accounted for as cash flow hedges, and resulted in a payment by the Company of $20 million upon issuance of the Pass Through Certificates. The effective portion of the hedge is being amortized to interest expense concurrent with the amortization of the debt and is reflected in the above table as a reduction in the debt balance. The ineffectiveness of the hedge transaction was immaterial. During December 2006 , the Company issued $300 million senior unsecured notes due December 15, 2016 . The notes bore interest at 5.75 percent . During fourth quarter 2009 , the Company entered into a fixed-to-floating interest rate swap to convert the interest on these unsecured notes to a floating rate; however, the interest rate swap was terminated in 2015. The notes matured and were redeemed in full on December 15, 2016, utilizing available cash on hand. During February 2005 , the Company issued $300 million senior unsecured notes due 2017 . The notes bear interest at 5.125 percent , payable semi-annually in arrears, with the first payment made on September 1, 2005 . In fourth quarter 2004 , the Company entered into four identical 13 -year floating-rate financing arrangements, whereby it borrowed a total of $112 million from French banking partnerships. Although the interest rates on the borrowings float, the Company estimated at inception that, considering the full effect of the “net present value benefits” included in the transactions, the effective economic yield over the 13 -year term of the loans will be approximately LIBOR minus 45 basis points. Principal and interest are payable semi-annually on June 30 and December 31 for each of the loans, and the Company may terminate the arrangements in any year on either of those dates, under certain conditions. The Company pledged four aircraft as collateral for the transactions. On February 28, 1997 , the Company issued $100 million of senior unsecured 7.375 percent debentures due March 1, 2027 . Interest is payable semi-annually on March 1 and September 1 . The debentures may be redeemed, at the option of the Company, in whole at any time or in part from time to time, at a redemption price equal to the greater of the principal amount of the debentures plus accrued interest at the date of redemption or the sum of the present values of the remaining scheduled payments of principal and interest thereon, discounted to the date of redemption at the comparable treasury rate plus 20 basis points, plus accrued interest at the date of redemption. In January 2007, the Company entered into an interest rate swap agreement to convert this fixed-rate debt to a floating rate; however, the interest rate swap was terminated in December 2012. The Company is required to provide standby letters of credit to support certain obligations that arise in the ordinary course of business. Although the letters of credit are an off-balance sheet item, the majority of the obligations to which they relate are reflected as liabilities in the Consolidated Balance Sheet. Outstanding letters of credit totaled $179 million at December 31, 2016 . The net book value of the assets pledged as collateral for the Company’s secured borrowings, primarily aircraft and engines, was $2.8 billion at December 31, 2016 . In addition, the Company has pledged a total of up to 82 of its Boeing 737-700 and 30 of its Boeing 737-800 aircraft at a net book value of $2.7 billion , in the case that it has obligations related to its fuel derivative instruments with counterparties that exceed certain thresholds. See Note 10 for further information on these collateral arrangements. As of December 31, 2016 , aggregate annual principal maturities of debt and capital leases (not including amounts associated with interest rate swap agreements, interest on capital leases, amortization of capital lease incentives, and amortization of purchase accounting adjustments) for the five-year period ending December 31, 2021, and thereafter, were $555 million in 2017, $323 million in 2018, $573 million in 2019, $797 million in 2020, $148 million in 2021, and $926 million thereafter. |

Leases [Abstract] | |
LEASES | LEASES The Company's fleet included 51 aircraft on capital lease as of December 31, 2016 , compared with 28 aircraft on capital lease, including one B717, as of December 31, 2015 . Amounts applicable to these aircraft that are included in property and equipment were: (in millions) 2016 2015 Flight equipment $ 923 $ 435 Less: accumulated amortization 82 29 $ 841 $ 406 Total rental expense for operating leases, both aircraft and other, charged to operations in 2016 , 2015 , and 2014 was $932 million , $909 million , and $931 million , respectively. The majority of the Company’s terminal operations space, as well as 83 aircraft, were under operating leases at December 31, 2016 . For aircraft operating leases and for terminal operations leases, expense is recorded on a straight-line basis and included in Aircraft rentals and in Landing fees and other rentals, respectively, in the Consolidated Statement of Income. Future minimum lease payments under capital leases and noncancelable operating leases and rentals to be received under subleases with initial or remaining terms in excess of one year at December 31, 2016 , were: (in millions) Capital leases Operating leases (b) Subleases LFMP facility lease* Operating leases, net 2017 $ 80 $ 671 $ (103 ) $ 24 $ 592 2018 80 562 (102 ) 25 485 2019 78 491 (97 ) 25 419 2020 78 377 (78 ) 26 325 2021 74 232 (41 ) 26 217 Thereafter 353 715 (26 ) 608 1,297 Total minimum lease payments $ 743 $ 3,048 $ (447 ) $ 734 $ 3,335 Less amount representing interest 128 Present value of minimum lease payments (a) 615 Less current portion 58 Long-term portion $ 557 * See Note 4 for further details (a) Excludes lease incentive obligation of $66 million . (b) Includes a portion of the Company's Construction obligation that has not yet been placed into service as of December 31, 2016. See Note 4 for further information. The aircraft leases generally can be renewed for one to five years at rates based on fair market value at the end of the lease term. Most aircraft leases have purchase options at or near the end of the lease term at fair market value, generally limited to a stated percentage of the lessor’s defined cost of the aircraft. 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 B717s to Delta at agreed-upon lease rates. The first converted B717 was delivered to Delta in September 2013 , and as of December 31, 2016 , the Company had delivered all B717s to Delta. A total of 76 of the B717s are on operating lease, ten are owned, and two are on capital lease. The Company paid 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 76 B717s on operating lease and the two B717s on capital lease coincide with the Company's remaining lease terms for these aircraft from the original lessor, which range from approximately two to seven years. The leasing of the ten B717s that are owned by the Company is subject to certain conditions, and the lease terms are for up to six years, after which Delta will have the option to purchase the aircraft at the then-prevailing market value. The ten owned B717s are accounted for as sales type leases, the two B717s classified by the Company as capital leases are accounted for as direct financing leases, and the remaining 76 subleases are accounted for as operating leases with Delta. There are no contingent payments and no significant residual value conditions associated with the transaction. The accounting for this transaction was based on the guidance provided for lease transactions. The Company recorded an initial charge of approximately $137 million during third quarter 2012 , representing 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 76 B717s that are 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. During 2014 , the Company recorded an additional $22 million in expense for its revised estimate of conversion costs for these B717s, and an additional $9 million associated with the extension of time between when the Company removed the aircraft from revenue service, on December 28, 2014, and when they entered the conversion process. The charges recorded by the Company for this transaction were included as a component of Acquisition and integration costs in the Company's Consolidated Statement of Income and were included as a component of Other, net in Cash flows from operating activities in the Company's Consolidated Statement of Cash Flows, and the corresponding liability for this transaction, which was not material as of December 31, 2016 or 2015 , is included as a component of Current liabilities and Other noncurrent liabilities in the Company's Consolidated Balance Sheet. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
STOCK PLANS | STOCK PLANS Share-based Compensation The Company accounts for share-based compensation utilizing fair value, which is determined on the date of grant for all instruments. The Consolidated Statement of Income for the years ended December 31, 2016 , 2015 , and 2014 , reflects share-based compensation expense of $33 million , $29 million , and $21 million , respectively. The total tax benefit recognized in earnings from share-based compensation arrangements for the years ended December 31, 2016 , 2015 , and 2014 , was not material . As of December 31, 2016 , there was $36 million of total unrecognized compensation cost related to share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.7 years. The Company expects substantially all unvested awards to vest. Restricted Stock Units and Stock Grants Under the Company’s Amended and Restated 2007 Equity Incentive Plan (“2007 Equity Plan”), it granted restricted stock units (“RSUs”) and performance-based restricted stock units (“PBRSUs”) to certain Employees during 2014 , 2015 , and 2016 . Outstanding RSUs vest over three years , subject generally to the individual’s continued employment or service. The PBRSUs granted in May 2014, January 2015, and January 2016 are subject to the Company’s performance with respect to a three-year simple average of Return on Invested Capital, before taxes and excluding special items ("ROIC"), for the defined performance period and the individual’s continued employment or service. The number of PBRSUs vesting on the vesting date will be interpolated based on the Company's ROIC performance and ranges from zero PBRSUs to 200 percent of granted PBRSUs. Forfeiture rates are estimated at the time of grant based on historical actuals for similar grants, and are trued-up to actuals over the vesting period. The Company recognizes all expense on a straight-line basis over the vesting period, with any changes in expense due to the number of PBRSUs expected to vest being modified on a prospective basis. Aggregated information regarding the Company’s RSUs and PBRSUs is summarized below: All Restricted Stock Units Units (000) Wtd. Average Fair Value (per share) Outstanding December 31, 2013, Unvested 2,584 $ 11.38 Granted 834 (a) 24.93 Vested (1,239 ) 11.05 Surrendered (102 ) 13.18 Outstanding December 31, 2014 2,077 16.92 Granted 561 (b) 45.80 Vested (1,095 ) 13.33 Surrendered (58 ) 25.49 Outstanding December 31, 2015 1,485 30.17 Granted 675 (c) 37.29 Vested (665 ) 23.29 Surrendered (56 ) 36.29 Outstanding December 31, 2016, Unvested 1,439 $ 36.52 (a) Includes 198 thousand PBRSUs (b) Includes 183 thousand PBRSUs (c) Includes 247 thousand PBRSUs In addition, the Company granted approximately 27 thousand shares of unrestricted stock at a weighted average grant price of $42.90 in 2016 , approximately 28 thousand shares at a weighted average grant price of $41.27 in 2015 , and approximately 36 thousand shares at a weighted average grant price of $24.91 in 2014 , to members of its Board of Directors. A remaining balance of up to 22 million shares of the Company’s common stock may be issued pursuant to grants under the 2007 Equity Plan. Employee Stock Purchase Plan Under the amended 1991 Employee Stock Purchase Plan ("ESPP"), which has been approved by Shareholders, the Company is authorized to issue up to a remaining balance of 9 million shares of the Company’s common stock to Employees of the Company. These shares may be issued at a price equal to 90 percent of the market value at the end of each monthly purchase period. Common stock purchases are paid for through periodic payroll deductions. For the years ended December 31, 2016 , 2015 , and 2014 , participants under the plan purchased 622 thousand shares, 597 thousand shares, and 792 thousand shares at average prices of $36.57 , $36.40 , and $23.17 , respectively. The weighted-average fair value of each purchase right under the ESPP granted for the years ended December 31, 2016 , 2015 , and 2014 , which is equal to the ten percent discount from the market value of the Common Stock at the end of each monthly purchase period, was $4.06 , $4.04 , and $2.68 , respectively. Taxes A portion of the Company’s granted options qualify as incentive stock options for income tax purposes. As such, a tax benefit is not recorded at the time the compensation cost related to the options is recorded for book purposes due to the fact that an incentive stock option does not ordinarily result in a tax benefit unless there is a disqualifying disposition. Grants of non-qualified stock options and RSUs result in the creation of a deferred tax asset, which is a temporary difference, until the time that the option is exercised or the RSU vests. With the issuance of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, all excess tax benefits and tax deficiencies are recorded through the income statement. Due to the treatment of incentive stock options, non-qualified stock options, and RSUs for tax purposes, the Company’s effective tax rate from year to year is subject to variability. |

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 24 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), put spreads (which include a purchased put option and a sold put option), and fixed price swap agreements in its portfolio. Although the use of collar structures and swap agreements can reduce the overall cost of hedging, these instruments carry more risk than purchased call options in that the Company could end up in a liability position when the collar structure or swap agreement settles. With the use of purchased call options and call spreads, the Company cannot be in a liability position at settlement, but does not have coverage once market prices fall below the strike price of the purchased call option. For the purpose of evaluating its net cash spend for jet fuel and for forecasting its future estimated jet fuel expense, the Company evaluates its hedge volumes strictly from an “economic” standpoint and thus does not consider whether the hedges 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 example, the Company may enter into “out-of-the-money” option contracts (including catastrophic protection), which may not generate intrinsic gains at settlement if market prices do not rise above the option strike price. Therefore, even though the Company may have an “economic” hedge in place for a particular period, that hedge may not produce any hedging gains at settlement and may even produce hedging losses depending on market prices, the types of instruments held, and the strike prices of those instruments. For 2016 , the Company had fuel derivative instruments in place for up to 46 percent of its fuel consumption. As of December 31, 2016 , the Company also had fuel derivative instruments in place to provide coverage for up to 63 percent of its 2017 estimated fuel consumption, depending on where market prices settle. The following table provides information about the Company’s volume of fuel hedging for the years 2017 through 2019 on an “economic” basis considering current market prices: Fuel hedged as of December 31, 2016 Derivative underlying commodity type as of Period (by year) (gallons in millions) (a) December 31, 2016 2017 1,281 WTI crude and Brent crude oil 2018 1,185 Brent crude oil 2019 305 Brent crude oil (a) Due to the types of derivatives utilized by the Company and different price levels of those contracts, these volumes represent the maximum economic hedge in place and 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 12 . The Company’s results are subject to the possibility that periodic changes will not be effective, as defined, or that the derivatives will no longer qualify for hedge accounting. Ineffectiveness results when the change in the fair value of the derivative instrument exceeds the change in the value of the Company’s expected future cash outlay to purchase and consume jet fuel. 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 Consolidated Statement of 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 Consolidated Statement of 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. When the Company has sold derivative positions in order to effectively “close” or offset a derivative already held as part of its fuel derivative instrument portfolio, any subsequent changes in fair value of those positions are marked to market through earnings. Likewise, any changes in fair value of those positions that were offset by entering into the sold positions and were de-designated as hedges are concurrently marked to market through earnings. However, any changes in value related to hedges that were deferred as part of AOCI while designated as a hedge would remain until the originally forecasted transaction occurs. 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 2014 , 2015 , or 2016 . Ineffectiveness is inherent in hedging jet fuel with derivative positions based in other crude oil related commodities. Due to the volatility in markets for crude oil and related products, the Company is unable to predict the amount of ineffectiveness each period, including the loss of hedge accounting, which could be determined on a derivative by derivative basis or in the aggregate for a specific commodity. This may result, and has resulted, in increased volatility in the Company’s financial results. Factors that have and may continue to lead to ineffectiveness and unrealized gains and losses on derivative contracts include: significant fluctuation in energy prices, the number of derivative positions the Company holds, significant weather events affecting refinery capacity and the production of refined products, and the volatility of the different types of products the Company uses in hedging. However, even though derivatives may not qualify for hedge accounting, the Company continues to hold the instruments as management believes derivative instruments continue to afford the Company the opportunity to stabilize jet fuel costs. Accounting pronouncements pertaining to derivative instruments and hedging are complex with stringent requirements, including the documentation of a Company hedging strategy, statistical analysis to qualify a commodity for hedge accounting both on a historical and a prospective basis, and strict contemporaneous documentation that is required at the time each hedge is designated by the Company. The Company also examines the effectiveness of each individual hedge and its entire hedging program on a quarterly basis utilizing statistical analysis. This analysis involves utilizing regression and other statistical analyses that compare changes in the price of jet fuel to changes in the prices of the commodities used for hedging purposes. All cash flows associated with purchasing and selling fuel derivatives are classified as Other operating cash flows in the Consolidated Statement of Cash Flows. The following table presents the location of all assets and liabilities associated with the Company’s hedging instruments within the Consolidated Balance Sheet: Asset derivatives Liability derivatives Balance Sheet Fair value at Fair value at Fair value at Fair value at (in millions) location 12/31/2016 12/31/2015 12/31/2016 12/31/2015 Derivatives designated as hedges* Fuel derivative contracts (gross) Prepaid expenses and other current assets $ 7 $ 2 $ 44 $ — Fuel derivative contracts (gross) Other assets 126 2 — — Fuel derivative contracts (gross) Accrued liabilities 4 107 412 526 Fuel derivative contracts (gross) Other noncurrent liabilities — 55 — 658 Interest rate derivative contracts Other assets — 2 — — Interest rate derivative contracts Other noncurrent liabilities — — 35 49 Total derivatives designated as hedges $ 137 $ 168 $ 491 $ 1,233 Derivatives not designated as hedges* Fuel derivative contracts (gross) Prepaid expenses and other current assets $ 54 $ 39 $ — $ 26 Fuel derivative contracts (gross) Other assets 52 5 52 — Fuel derivative contracts (gross) Accrued liabilities 201 1,395 262 1,854 Fuel derivative contracts (gross) Other noncurrent liabilities — 330 — 352 Total derivatives not designated as hedges $ 307 $ 1,769 $ 314 $ 2,232 Total derivatives $ 444 $ 1,937 $ 805 $ 3,465 * Represents the position of each trade before consideration of offsetting positions with each counterparty and does not include the impact of cash collateral deposits provided to or received from counterparties. See discussion of credit risk and collateral following in this Note. In addition, the Company also had the following amounts associated with fuel derivative instruments and hedging activities in its Consolidated Balance Sheet: Balance Sheet December 31, December 31, (in millions) location 2016 2015 Cash collateral deposits held from counterparties for fuel contracts - current Offset against Prepaid expenses and other current assets $ 4 $ — Cash collateral deposits held from counterparties for fuel contracts - noncurrent Offset against Other assets 6 — Cash collateral deposits provided to counterparties for fuel contracts - current Offset against Accrued liabilities 311 235 Cash collateral deposits provided to counterparties for fuel contracts- noncurrent Offset against Other noncurrent liabilities — 600 Due to third parties for fuel contracts Accounts payable 75 46 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 Consolidated Balance Sheet are those in which the Company pays or receives cash for transactions with the same counterparty 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 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. 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: Offsetting of derivative assets (in millions) (i) (ii) (iii) = (i) + (ii) (i) (ii) (iii) = (i) + (ii) December 31, 2016 December 31, 2015 Description Balance Sheet location Gross amounts of recognized assets Gross amounts offset in the Balance Sheet Net amounts of assets presented in the Balance Sheet Gross amounts of recognized assets Gross amounts offset in the Balance Sheet Net amounts of assets presented in the Balance Sheet Fuel derivative contracts Prepaid expenses and other current assets $ 61 $ (48 ) $ 13 $ 41 $ (26 ) $ 15 Fuel derivative contracts Other assets $ 178 $ (58 ) $ 120 (a) $ 7 $ — $ 7 (a) Fuel derivative contracts Accrued liabilities $ 516 $ (516 ) $ — (a) $ 1,737 $ (1,737 ) $ — (a) Fuel derivative contracts Other noncurrent liabilities $ — $ — $ — (a) $ 985 $ (985 ) $ — (a) Interest rate derivative contracts Other assets $ — $ — $ — (a) $ 2 $ — $ 2 (a) (a) The net amounts of derivative assets and liabilities are reconciled to the individual line item amounts presented in the Consolidated Balance Sheet in Note 5 .

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 Consolidated Statement of 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 December 31, 2016 , recorded in AOCI, were approximately $302 million in unrealized losses , net of taxes, which are expected to be realized in earnings during the twelve months subsequent to December 31, 2016 . 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. Several of the Company's interest rate swap agreements 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 that do not qualify for the "shortcut" method of accounting, ineffectiveness is required to be measured at each reporting period. The ineffectiveness associated with all of the Company’s, including AirTran Holdings', interest rate swap agreements for all periods presented was not material. The fair values of the interest rate swap agreements, which are adjusted regularly, have been aggregated by counterparty for classification in the Consolidated Balance Sheet. Agreements totaling a net liability of $35 million are fair value hedges, cash flow hedges, and interest rate derivatives not utilizing hedge accounting, are classified as a component of Other noncurrent liabilities. The corresponding adjustment related to the net liability associated with the Company’s cash flow hedges is to AOCI, fair value hedges is to the carrying value of the long-term debt, and interest rate derivatives not utilizing hedge accounting is to Interest expense. See Note 12 . The Company has fixed-to-floating interest rate swap agreements in place associated with its $500 million 2.65 percent Notes due 2020 and its $300 million 2.75 percent Notes due 2019 that are accounted for as fair value hedges. As a result of the fixed-to-floating interest rate swap agreements in place, the average floating rate recognized during 2016 was approximately 2.03 percent on the $500 million Note, and approximately 1.85 percent on the $300 million Note, based on actual and forward rates as of December 31, 2016 . The Company has floating-to-fixed interest rate swap agreements associated with its $600 million floating-rate term loan agreement due 2020 and its $332 million term loan agreement due 2019 that are accounted for as cash flow hedges. These interest rate hedges have fixed the interest rate on the $600 million floating-rate term loan agreement at 5.223 percent until maturity, and for the $332 million term loan agreement at 6.315 percent until maturity. There are also a number of interest rate swap agreements, which convert a portion of AirTran Holdings' floating-rate debt to a fixed-rate basis for the remaining life of the debt, thus reducing the impact of interest rate changes on future interest expense and cash flows. Under these agreements, which expire between 2017 and 2020 , it pays fixed rates between 4.35 percent and 6.435 percent and receives either three-month or six-month LIBOR on the notional values. The notional amount of outstanding debt related to interest rate swaps as of December 31, 2016 , was $166 million . These interest rate swap arrangements were designated as cash flow hedges as of the acquisition date, and subsequently de-designated during fourth quarter 2016 as the Company no longer believes these hedges will be highly effective in offsetting future cash flows. The mark-to-market impact associated with these 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 December 31, 2016 , 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 December 31, 2016 , at which such postings are triggered: Counterparty (CP) (in millions) A B C D E F Other (a) Total Fair value of fuel derivatives $ (298 ) $ (78 ) $ 36 $ (5 ) $ 3 $ 12 $ 4 $ (326 ) Cash collateral held from (by) CP (279 ) (33 ) — — — 11 — (301 ) Aircraft collateral pledged to CP — — — — — — — — Letters of credit (LC) — — — — — — — — Option to substitute LC for aircraft (200) to (600)(h) (100) to (500)(d) N/A (150) to (550)(d) (150) to (550)(d) N/A Option to substitute LC for cash N/A >(500)(e) (225) to (275)(e) (75) to (150) or >(550)(e) (125) to (150) or >(550)(e) (g) If credit rating is investment grade, fair value of fuel derivative level at which: Cash is provided to CP (50) to (200) or >(600) (50) to (100) or >(500) >(125) (75) to (150) or >(550) (125) to (150) or >(550) >(100) Cash is received from CP >50(c) >150(c) >175(c) >250(c) >75(c) >0(c) Aircraft or cash can be pledged to CP as collateral (200) to (600)(f) (100) to (500)(d) N/A (150) to (550)(d) (150) to (550)(d) N/A If credit rating is non-investment grade, fair value of fuel derivative level at which: Cash is provided to CP (0) to (200) or >(600) (0) to (100) or >(500) (b) (0) to (150) or >(550) (0) to (150) or >(550) (b) Cash is received from CP (b) (b) (b) (b) (b) (b) Aircraft or cash can be pledged to CP as collateral (200) to (600) (100) to (500) N/A (150) to (550) (150) to (550) N/A (a) Individual counterparties with fair value of fuel derivatives < $3 million .

Fair Value Disclosures [Abstract] | |
FAIR VALUE MEASUREMENTS | 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 December 31, 2016 , 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 and certificates of deposit), 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. 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 10 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. Included in Other available-for-sale securities are the Company's investments associated with its deferred compensation plans, which consist of mutual funds that are publicly traded and for which market prices are readily available. These plans are non-qualified deferred compensation plans designed to hold contributions in excess of limits established by the Internal Revenue Code of 1986, as amended. The distribution timing and payment amounts under these plans are made based on the participant's distribution election and plan balance. Assets related to the funded portions of the deferred compensation plans are held in a rabbi trust, and the Company remains liable to these participants for the unfunded portion of the plans. The Company records changes in the fair value of the assets in the Company's earnings. The following tables present the Company’s assets and liabilities that are measured at fair value on a recurring basis at December 31, 2016 , and December 31, 2015 : Fair value measurements at reporting date using: Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Description December 31, 2016 (Level 1) (Level 2) (Level 3) Assets (in millions) Cash equivalents Cash equivalents (a) $ 1,344 $ 1,344 $ — $ — Commercial paper 325 — 325 — Certificates of deposit 11 — 11 — Short-term investments: Treasury bills 1,345 1,345 — — Certificates of deposit 280 — 280 — Fuel derivatives: Swap contracts (c) 42 — 42 — Option contracts (b) 239 — — 239 Option contracts (c) 163 — — 163 Other available-for-sale securities 83 83 — — Total assets $ 3,832 $ 2,772 $ 658 $ 402 Liabilities Fuel derivatives: Swap contracts (c) $ (110 ) $ — $ (110 ) $ — Option contracts (b) (96 ) — — (96 ) Option contracts (c) (564 ) — — (564 ) Interest rate derivatives (see Note 10) (35 ) — (35 ) — Total liabilities $ (805 ) $ — $ (145 ) $ (660 ) (a) Cash equivalents are primarily composed of money market investments.

(b) In the Consolidated Balance Sheet amounts are presented as a net asset. See Note 10 . (c) In the Consolidated Balance Sheet amounts are presented as a net liability. See Note 10 . The Company had no transfers of assets or liabilities between any of the above levels during the years ended December 31, 2016 or 2015 . The Company did not have any assets or liabilities measured at fair value on a nonrecurring basis as of December 31, 2016 or 2015 . The following tables present the Company’s activity for items measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for 2016 and 2015 : Fair value measurements using significant unobservable inputs (Level 3) Fuel Other (in millions) derivatives securities Total Balance at December 31, 2015 $ (1,676 ) $ 27 $ (1,649 ) Total gains (losses) (realized or unrealized) Included in earnings 175 (2 ) 173 Included in other comprehensive income 201 8 209 Purchases 221 (a) — 221 Sales (61 ) (a) (33 ) (94 ) Settlements 882 — 882 Balance at December 31, 2016 $ (258 ) $ — $ (258 ) The amount of total gains for the period included in earnings attributable to the change in unrealized gains or losses relating to assets still held at December 31, 2016 $ 93 $ — $ 93 (a) The purchase and sale of fuel derivatives are recorded gross based on the structure of the derivative instrument and whether a contract with multiple derivatives is purchased as a single instrument or separate instruments.

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 following table presents a range of the unobservable inputs utilized in the fair value measurements of the Company’s fuel derivatives classified as Level 3 at December 31, 2016 : Quantitative information about Level 3 fair value measurements Valuation technique Unobservable input Period (by year) Range Fuel derivatives Option model Implied volatility 2017 16-36% 2018 20-31% 2019 18-24% 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 December 31, 2016 , 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. Eight 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.

Contributions under all defined contribution plans are primarily based on Employee compensation and performance of the Company. The Company sponsors Employee savings plans under section 401(k) of the Internal Revenue Code of 1986, as amended, which include Company matching contributions. In addition, the Southwest Airlines Co. ProfitSharing Plan (ProfitSharing Plan) is a defined contribution plan to which the Company may contribute a percentage of its eligible pre-tax profits, as defined, on an annual basis. No Employee contributions to the ProfitSharing Plan are allowed. Amounts associated with the Company's defined contribution plans expensed in 2016 , 2015 , and 2014 , reflected as a component of Salaries, wages, and benefits, were $937 million , $945 million , and $644 million , respectively. Postretirement Benefit Plans The Company provides postretirement benefits to qualified retirees in the form of medical and dental coverage. Employees must meet minimum levels of service and age requirements as set forth by the Company, or as specified in collective-bargaining agreements with specific workgroups. Employees meeting these requirements, as defined, may use accrued unused sick time to pay for medical and dental premiums from the age of retirement until age 65 . The following table shows the change in the accumulated postretirement benefit obligation (APBO) for the years ended December 31, 2016 and 2015 : (in millions) 2016 2015 APBO at beginning of period $ 201 $ 169 Service cost 13 11 Interest cost 9 7 Benefits paid (6 ) (6 ) Actuarial loss 38 20 Plan amendments 1 — APBO at end of period $ 256 $ 201 All plans are unfunded, and benefits are paid as they become due. Estimated future benefit payments expected to be paid are $7 million in 2017 , $8 million in 2018 , $9 million in 2019 , $10 million in 2020 , $12 million in 2021 , and $90 million for the next five years thereafter. The funded status (the difference between the fair value of plan assets and the projected benefit obligations) of the Company’s consolidated benefit plans are recognized in the Consolidated Balance Sheet, with a corresponding adjustment to AOCI. The following table reconciles the funded status of the plans to the accrued postretirement benefit cost recognized in Other non-current liabilities on the Company’s Consolidated Balance Sheet at December 31, 2016 and 2015 . (in millions) 2016 2015 Funded status $ (256 ) $ (201 ) Unrecognized net actuarial (gain)/loss 7 (31 ) Unrecognized prior service cost 7 9 Accumulated other comprehensive income (loss) (14 ) 22 Cost recognized on Consolidated Balance Sheet $ (256 ) $ (201 ) The consolidated periodic postretirement benefit cost for the years ended December 31, 2016 , 2015 , and 2014 , included the following: (in millions) 2016 2015 2014 Service cost $ 13 $ 11 $ 10 Interest cost 9 7 7 Amortization of prior service cost 3 3 3 Recognized actuarial gain — (3 ) (4 ) Settlements — — (1 ) Net periodic postretirement benefit cost $ 25 $ 18 $ 15 Unrecognized prior service cost is expensed using a straight-line amortization of the cost over the average future service of Employees expected to receive benefits under the plans. Actuarial gains are amortized utilizing the minimum amortization method. The following actuarial assumptions were used to account for the Company’s postretirement benefit plans at December 31, 2016 , 2015 , and 2014 : 2016 2015 2014 Weighted-average discount rate 4.25 % 4.50 % 4.10 % Assumed healthcare cost trend rate (1) 7.08 % 7.08 % 6.88 % (1) The assumed healthcare cost trend rate is assumed to remain at 7.08% for 2017 , then decline gradually to 5.19% by 2027 and remain level thereafter. The assumed healthcare cost trend rates have a significant effect on the amounts reported for the consolidated postretirement plans. A one percent change in all healthcare cost trend rates used in measuring the APBO at December 31, 2016 , would have the following effects: (in millions) 1% increase 1% decrease Increase (decrease) in total service and interest costs $ 4 $ (3 ) Increase (decrease) in the APBO $ 36 $ (31 ) The selection of a discount rate is made annually and is selected by the Company based upon comparison of the expected future cash flows associated with the Company’s future payments under its consolidated postretirement obligations to a yield curve created using high quality bonds that closely match those expected future cash flows. This rate decreased during 2016 due to market conditions. The assumed healthcare trend rate is also reviewed at least annually and is determined based upon both historical experience with the Company’s healthcare benefits paid and expectations of how those trends may or may not change in future years. |

QUARTERLY FINANCIAL DATA | QUARTERLY FINANCIAL DATA (unaudited) Three months ended (in millions except per share amounts) March 31 June 30 Sept. 30 Dec. 31 2016 Operating revenues (a) $ 4,826 $ 5,384 $ 5,139 $ 5,076 Operating income 944 1,276 695 846 Income before income taxes 816 1,304 618 809 Net income (b) 513 820 388 522 Net income per share, basic (a)(b) 0.80 1.30 0.63 0.85 Net income per share, diluted (a)(b) 0.79 1.28 0.62 0.84 March 31 June 30 Sept. 30 Dec. 31 2015 Operating revenues (a) $ 4,414 $ 5,111 $ 5,318 $ 4,977 Operating income 780 1,085 1,225 1,026 Income before income taxes 723 977 933 847 Net income 453 608 584 536 Net income per share, basic (a) 0.67 0.91 0.89 0.83 Net income per share, diluted (a) 0.66 0.90 0.88 0.82 (a) Includes the impact of the Agreement with Chase and the resulting required change in accounting methodology. The impact of this change during third quarter and fourth quarter 2015 resulted in increases to Operating revenue of approximately $303 million and $124 million , respectively, and increased Basic and Diluted net income per share by approximately $.24 in third quarter 2015 and by approximately $.10 in fourth quarter 2015. The impact of this change resulted in an increase to Operating revenue during first quarter 2016 of approximately $115 million and increased Basic and Diluted net income per share by approximately $.10 and $.09 , respectively. The impact of this change resulted in an increase to Operating revenue during second quarter 2016 of approximately $137 million , and increased Basic and Diluted net income per share by approximately $.12 and $.11 , respectively. See Note 1 for further detail. (b) During second quarter 2016, the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, with an effective date as of January 1, 2016. The prospective method of adoption of this standard resulted in the recognition of $2 million of excess tax benefits to the Company's income tax provision for the six months ended June 30, 2016, but which were related to first quarter 2016. For this presentation and in future periods in which first quarter 2016 results are reported, these amounts are reflected in the appropriate period. The adoption had no impact to net income per share amounts. See Note 2 for further information. |
Summary of Significant Accoun25
Summary of Significant Accounting Policies (Policies) | 12 Months Ended |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation Southwest Airlines Co. (the “Company”) operates Southwest Airlines, a major domestic airline. The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries, which include AirTran Holdings, LLC. The Company owns all of the outstanding equity of AirTran Holdings, Inc. (“AirTran Holdings”), the former parent company of AirTran Airways, Inc. (“AirTran Airways”). Throughout these Notes, the Company makes reference to AirTran, which is meant to be inclusive of AirTran Holdings, LLC, the successor to AirTran Holdings, and its subsidiaries, including among others, AirTran Airways. AirTran's final passenger service was on December 28, 2014. All integration costs were incurred in periods prior to 2016. The accompanying Consolidated Financial Statements include the results of operations and cash flows for all periods presented and all significant inter-entity balances and transactions have been eliminated. The preparation of financial statements in conformity with generally accepted accounting principles in the United States (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. |
Cash and cash equivalents | Cash and Cash Equivalents Cash in excess of that necessary for operating requirements is invested in short-term, highly liquid, income-producing investments. Investments with original maturities of three months or less when purchased are classified as cash and cash equivalents, which primarily consist of certificates of deposit, money market funds, and investment grade commercial paper issued by major corporations and financial institutions. Cash and cash equivalents are stated at cost, which approximates fair value. As of December 31, 2016 , $301 million in net cash collateral deposits were provided by the Company to its fuel hedge counterparties and no cash collateral deposits were held by or provided by the Company to its interest rate hedge counterparties. As of December 31, 2015 , $835 million in cash collateral deposits were provided by the Company to its fuel hedge counterparties and no cash collateral deposits were held by or provided by the Company to its interest rate hedge counterparties. Cash collateral amounts provided or held associated with fuel and interest rate derivative instruments are not restricted in any way and earn interest income at an agreed upon rate that approximates the rates earned on short-term securities issued by the U.S. Government. Depending on the fair value of the Company’s fuel and interest rate derivative instruments, the amounts of collateral deposits held or provided at any point in time can fluctuate significantly. See Note 10 for further information on these collateral deposits and fuel derivative instruments. |
Short-term and noncurrent investments | Short-term and Noncurrent Investments Short-term investments consist of investments with original maturities of greater than three months but less than twelve months when purchased. These are primarily short-term securities issued by the U.S. Government and certificates of deposit issued by domestic banks. All of these investments are classified as available-for-sale securities and are stated at fair value, which approximates cost. For all short-term investments, at each reset period or upon reinvestment, the Company accounts for the transaction as Proceeds from sales of short-term investments for the security relinquished, and Purchases of short-investments for the security purchased, in the accompanying Consolidated Statement of Cash Flows. Unrealized gains and losses, net of tax, if any, are recognized in Accumulated other comprehensive income (loss) (“AOCI”) in the accompanying Consolidated Balance Sheet. Realized net gains and losses on specific investments, if any, are reflected in Interest income in the accompanying Consolidated Statement of Income. Both unrealized and realized gains and/or losses associated with investments were immaterial for all years presented. Noncurrent investments consist of investments with maturities of greater than twelve months. Noncurrent investments are included as a component of Other assets in the Consolidated Balance Sheet. |
Accounts and other receivables | Accounts and Other Receivables Accounts and other receivables are carried at cost. They primarily consist of amounts due from credit card companies associated with sales of tickets for future travel, and amounts due from business partners in the Company’s frequent flyer program. The allowance for doubtful accounts was immaterial at December 31, 2016 and 2015 . In addition, the provision for doubtful accounts and write-offs for 2016 , 2015 , and 2014 were each immaterial. |
Inventories | Inventories Inventories primarily consist of aircraft fuel, flight equipment expendable parts, materials, and supplies. All of these items are carried at average cost, less an allowance for obsolescence. These items are generally charged to expense when issued for use. The reserve for obsolescence was $57 million and $47 million at December 31, 2016 , and 2015 , respectively. In addition, the Company’s provision for obsolescence and write-offs for 2016 , 2015 , and 2014 were each immaterial. |
Property and equipment | Property and Equipment Property and equipment is stated at cost. Capital expenditures includes payments made for aircraft, other flight equipment, purchase deposits related to future aircraft deliveries, and ground and other property and equipment. Depreciation is provided by the straight-line method to estimated residual values over periods generally ranging from 23 to 25 years for flight equipment, 5 to 30 years for ground property and equipment, and 25 to 30 years, or the expected term of the Company's lease if shorter, for Assets constructed for others, once the asset is placed in service. Residual values estimated for aircraft generally range from 2 to 20 percent , for ground property and equipment generally range from 0 to 10 percent , and for Assets constructed for others range from 17 to 25 percent . Property under capital leases and related obligations are initially recorded at an amount equal to the present value of future minimum lease payments computed on the basis of the Company’s incremental borrowing rate or, when known, the interest rate implicit in the lease. Amortization of property under capital leases is on a straight-line basis over the lease term and is included in Depreciation and amortization expense. Leasehold improvements generally are amortized on a straight-line basis over the shorter of the estimated useful life of the improvement or the remaining term of the lease. Assets constructed for others primarily consists of airport improvement projects, once placed into service, in which the Company is considered the accounting owner of the facilities. See Note 4 for further information. During first quarter 2016, the Company made the decision to further simplify its operations and accelerate the retirement of its less-efficient Classic fleet to no later than third quarter 2017, versus the original scheduled retirement of this fleet that had extended out to 2021. This change in retirement dates is considered a change in estimate and has been accounted for on a prospective basis as of the dates the decisions were finalized. Therefore, the Company has recorded and will record accelerated depreciation expense over the remainder of the useful lives for each Classic aircraft and related parts. See Note 7 for further information regarding the Company's aircraft fleet. (in millions, except per share amounts) Year ended December 31, 2016 Depreciation and amortization expense $ 123 Net income * $ (66 ) Net income per basic share $ (0.11 ) Net income per diluted share $ (0.10 ) * net of profitsharing benefit The estimated impact to Depreciation and amortization expense from this change in assumption for 2017 is an approximate increase of $21 million . The Company evaluates its long-lived assets used in operations for impairment when events and circumstances indicate that the undiscounted cash flows to be generated by that asset are less than the carrying amounts of the asset and may not be recoverable. Factors that would indicate potential impairment include, but are not limited to, significant decreases in the market value of the long-lived asset(s), a significant change in the long-lived asset’s physical condition, and operating or cash flow losses associated with the use of the long-lived asset. If an asset is deemed to be impaired, an impairment loss is recorded for the excess of the asset book value in relation to its estimated fair value. |
Aircraft and engine maintenance | Aircraft and Engine Maintenance The cost of scheduled inspections and repairs and routine maintenance costs for all aircraft and engines are charged to Maintenance materials and repairs expense as incurred. The Company also has “power-by-the-hour” agreements related to certain of its aircraft engines with external service providers. Under these agreements, which the Company has determined effectively transfer the risk and create an obligation associated with the maintenance on such engines to the counterparty, expense is recorded commensurate with each hour flown on an engine. In situations where the payments to the counterparty do not sufficiently match the level of services received during the period, expense is recorded on a straight-line basis over the term of the agreement based on the Company's best estimate of expected future aircraft utilization. For its engine maintenance contracts that do not transfer risk to the service provider, the Company records expense on a time and materials basis when an engine repair event takes place. Modifications that significantly enhance the operating performance or extend the useful lives of aircraft or engines are capitalized and amortized over the remaining life of the asset. |
Goodwill and intangible assets | Goodwill and Intangible Assets The Company applies a fair value based impairment test to the carrying value of goodwill and indefinite-lived intangible assets annually on October 1st, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred. The Company assesses the value of goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Under a qualitative approach, the Company considers various market factors, including applicable key assumptions listed below. These factors are analyzed to determine if events and circumstances could reasonably have affected the fair value of goodwill and indefinite-lived intangible assets. If the Company determines that it is more likely than not that an indefinite-lived intangible asset is impaired, the quantitative approach is used to assess the asset’s implied fair value and the amount of the impairment. Under a quantitative approach, the implied fair value of the Company's identifiable assets and liabilities is calculated based on key assumptions. If the Company assets' carrying value exceeds the fair value calculated using the quantitative approach, an impairment charge is recorded for the difference in fair value and carrying value. The following table is a summary of the Company’s intangible assets, which are included as a component of Other assets in the Company's Consolidated Balance Sheet, as of December 31, 2016 and 2015 : Year ended December 31, 2016 Year ended December 31, 2015 (in millions) Weighted-average useful life (in years) Gross carrying amount Accumulated amortization Gross carrying amount Accumulated Amortization Customer relationships/marketing agreements 9 $ 38 $ 32 $ 38 $ 30 Trademarks/trade names 6 36 36 36 34 Owned domestic slots (a) Indefinite 295 — 303 n/a Leased domestic slots (a) — — — 17 3 Gate leasehold rights (b) 15 180 55 180 43 Total 13 $ 549 $ 123 $ 574 $ 110 (a) The Company recorded a $21 million impairment associated with owned and leased slots at Newark Liberty International Airport as a result of the FAA announcement, in April 2016, that this airport was being changed to a Level 2 schedule-facilitated airport from its previous designation as Level 3. (b) Intangible assets primarily consist of acquired leasehold rights to certain airport owned gates, takeoff and landing slots (a “slot” is the right of an air carrier, pursuant to regulations of the FAA, to operate a takeoff or landing at a specific time at certain airports) at certain domestic slot-controlled airports, and certain intangible assets acquired. The aggregate amortization expense for 2016 , 2015 , and 2014 was $17 million , $19 million , and $13 million , respectively. Estimated aggregate amortization expense for the five succeeding years and thereafter is as follows: 2017 – $13 million , 2018 – $13 million , 2019 – $13 million , 2020 – $12 million , 2021 – $12 million , and thereafter – $68 million . |
Revenue recognition | Revenue Recognition Tickets sold are initially deferred as Air traffic liability. Passenger revenue is recognized when transportation is provided. Air traffic liability primarily represents tickets sold for future travel dates and funds that are past flight date and remain unused. The majority of the Company’s tickets sold are nonrefundable. Refundable tickets that are sold but not flown on the travel date can be reused for another flight, up to a year from the date of sale, or refunded. A small percentage of tickets (or partial tickets) expire unused. The Company estimates the amount of tickets that expire unused and recognizes such amounts in Passenger revenue using the redemption method based on the scheduled flight date. Southwest has a No Show policy that applies to certain nonrefundable fares that are not canceled or changed by a Customer at least ten minutes prior to a flight's scheduled departure. Based on the Company's revenue recognition policy, revenue is recorded at the flight date for a Customer who does not change his/her itinerary and loses his/her funds. Amounts collected from passengers for ancillary service fees are generally recognized as Other revenue when the service is provided, which is typically the flight date. The Company's policy is to record revenue for the estimated spoilage of tickets (including partial tickets) once the flight date has passed, under the redemption method. Initial spoilage estimates are routinely adjusted and ultimately finalized once the tickets expire, which is typically twelve months after the original purchase date. Spoilage estimates are based on the Customers' historical travel behavior as well as assumptions about the Customers' future travel behavior. Assumptions used to generate spoilage estimates can be impacted by several factors including, but not limited to: fare increases, fare sales, changes to the Company's ticketing policies, changes to the Company’s refund, exchange and unused funds policies, and economic factors. The Company is also required to collect certain taxes and fees from Customers on behalf of government agencies and remit these back to the applicable governmental entity on a periodic basis. These taxes and fees include foreign and U.S. federal transportation taxes, federal security charges, and airport passenger facility charges. These items are collected from Customers at the time they purchase their tickets, but are not included in Passenger revenue. The Company records a liability upon collection from the Customer and relieves the liability when payments are remitted to the applicable governmental agency. |
Frequent flyer program | Frequent Flyer Program The Company records a liability for the estimated incremental cost of providing free travel under its frequent flyer program for all amounts earned from flight activity that are expected to be redeemed for future travel. The estimated incremental cost includes direct passenger costs such as fuel, food, and other operational costs, but does not include any contribution to fixed overhead costs or profit. Southwest also sells frequent flyer points and related services to companies participating in its frequent flyer program. Historically, until July 1, 2015, funds received from the sale of points associated with these agreements were accounted for under the residual method. Under this method, the Company estimated the portion of the amounts received from the sale of frequent flyer points that related to free travel and these amounts were deferred and recognized as Passenger revenue when the ultimate free travel awards were flown. Effective July 1, 2015, the Company entered into an amended co-branded credit card agreement ("Agreement") with Chase Bank USA, N.A. (“Chase”), through which the Company sells loyalty points and other items to Chase. This material modification triggered an accounting change under ASU 2009-13, which was recorded on a prospective basis. The impact of the accounting change is that the Company estimated the selling prices and volumes over the term of the Agreement in order to determine the allocation of proceeds to each of the deliverables (travel points to be awarded; use of the Southwest Airlines’ brand and access to Rapid Reward Member lists; advertising elements; and the Company’s resource team). The Company records passenger revenue related to air transportation and certificates for discounted companion travel when the transportation is delivered. The other elements are recognized as Other - net revenue when earned. The Company followed the transition approach of ASU 2009-13, which required that the Company adjust the existing deferred revenue balance, classified within Air traffic liability, to reflect the value, on a relative selling price basis, of any undelivered element remaining at the date of contract modification. The relative selling price of the undelivered element (air transportation) was lower than the rate at which it had been deferred under the residual method, and the Company recorded a one-time, non-cash adjustment to decrease frequent flyer deferred revenue and increase revenue through the recording of a Special revenue adjustment of $172 million in 2015. The estimated impacts on revenue and earnings associated with the Agreement and this change in accounting principle recognized subsequent to the effective date of July 1, 2015, are as follows: (in millions, except per share amounts) Year ended December 31, 2016 Year ended December 31, 2015 Passenger revenue $ (250 ) $ (89 ) Special revenue adjustment — 172 Other revenue 794 344 Operating revenues $ 544 $ 427 Net income $ 293 $ 227 Net income per basic share $ 0.47 $ 0.34 Net income per diluted share $ 0.46 $ 0.34 For all points sold to business partners that are expected to expire unused, the Company recognizes spoilage in accordance with the redemption method. The Company’s consolidated liability associated with the sale of frequent flyer points, was approximately $1.4 billion and $1.3 billion as of December 31, 2016 , and 2015 , respectively, which is classified within Air traffic liability. During fourth quarter 2014, the Company obtained sufficient historical behavioral data to develop a predictive statistical model to analyze the amount of spoilage expected for points sold to business partners, which indicated an increase in the expected spoilage rate. This change in estimate was recorded on a prospective basis, as of October 1, 2014. The impacts on revenue and earnings were as follows: (in millions, except per share amounts) Year ended December 31, 2015 Year ended December 31, 2014 Passenger revenue $ 115 $ 55 Net income $ 61 $ 29 Net income per basic share $ 0.09 $ 0.04 Net income per diluted share $ 0.09 $ 0.04 The Company continues to evaluate annually in October, but these analyses have not resulted in a material adjustment. |
Advertising | Advertising Advertising costs are charged to expense as incurred. Advertising and promotions expense for the years ended December 31, 2016 , 2015 , and 2014 was $232 million , $218 million , and $207 million , respectively, and is included as a component of Other operating expense in the accompanying Consolidated Statement of Income. |
Share-based Employee compensation | Share-based Employee Compensation The Company has share-based compensation plans covering certain Employees, including a plan that also covers the Company’s Board of Directors. The Company accounts for share-based compensation based on its grant date fair value. See Note 9 for further information. Outstanding RSUs vest over three years , subject generally to the individual’s continued employment or service. The PBRSUs granted in May 2014, January 2015, and January 2016 are subject to the Company’s performance with respect to a three-year simple average of Return on Invested Capital, before taxes and excluding special items ("ROIC"), for the defined performance period and the individual’s continued employment or service. The number of PBRSUs vesting on the vesting date will be interpolated based on the Company's ROIC performance and ranges from zero PBRSUs to 200 percent of granted PBRSUs. A portion of the Company’s granted options qualify as incentive stock options for income tax purposes. As such, a tax benefit is not recorded at the time the compensation cost related to the options is recorded for book purposes due to the fact that an incentive stock option does not ordinarily result in a tax benefit unless there is a disqualifying disposition. Grants of non-qualified stock options and RSUs result in the creation of a deferred tax asset, which is a temporary difference, until the time that the option is exercised or the RSU vests. With the issuance of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, all excess tax benefits and tax deficiencies are recorded through the income statement. Due to the treatment of incentive stock options, non-qualified stock options, and RSUs for tax purposes, the Company’s effective tax rate from year to year is subject to variability. The Company accounts for share-based compensation utilizing fair value, which is determined on the date of grant for all instruments. |
Fair Value of Financial Instruments | Financial Derivative Instruments The Company accounts for financial derivative instruments at fair value and applies hedge accounting rules where appropriate. The Company utilizes various derivative instruments, including jet fuel, crude oil, unleaded gasoline, and heating oil-based derivatives, to attempt to reduce the risk of its exposure to jet fuel price increases. These instruments consist primarily of purchased call options, collar structures, call spreads, put spreads, and fixed price swap agreements, and upon proper qualification are accounted for as cash-flow hedges. The Company also has interest rate swap agreements to convert a portion of its fixed-rate debt to floating rates and has swap agreements that convert certain floating-rate debt to a fixed-rate. These interest rate hedges are appropriately designated as either fair value hedges or as cash flow hedges. Since the majority of the Company’s financial derivative instruments are not traded on a market exchange, the Company estimates their fair values. Depending on the type of instrument, the values are determined by the use of present value methods or option value models with assumptions about commodity prices based on those observed in underlying markets. Also, since there is not a reliable forward market for jet fuel, the Company must estimate the future prices of jet fuel in order to measure the effectiveness of the hedging instruments in offsetting changes to those prices. Forward jet fuel prices are estimated through utilization of a statistical-based regression equation with data from market forward prices of like commodities. This equation is then adjusted for certain items, such as transportation costs, that are stated in the Company’s fuel purchasing contracts with its vendors. For the effective portion of settled fuel hedges, the Company records the associated gains or losses as a component of Fuel and oil expense in the Consolidated Statement of Income. For amounts representing ineffectiveness, as defined, or changes in fair value of derivative instruments for which hedge accounting is not applied, the Company records any gains or losses as a component of Other (gains) losses, net, in the Consolidated Statement of Income. Amounts that are paid or received in connection with the purchase or sale of financial derivative instruments (i.e., premium costs of option contracts) are classified as a component of Other (gains) losses, net, in the Consolidated Statement of Income in the period in which the instrument settles or expires. All cash flows associated with purchasing and selling derivatives are classified as operating cash flows in the Consolidated Statement of Cash Flows, within Changes in certain assets and liabilities. See Note 10 for further information on hedge accounting and financial derivative instruments. The Company classifies its cash collateral provided to or held from counterparties in a “net” presentation on the Consolidated Balance Sheet against the fair value of the derivative positions with those counterparties. See Note 10 for further information. 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 December 31, 2016 , 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 and certificates of deposit), 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. 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 10 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 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. |
Software capitalization | Software Capitalization The Company capitalizes certain internal and external costs related to the acquisition and development of internal use software during the application development stages of projects. The Company amortizes these costs using the straight-line method over the estimated useful life of the software, which is typically five to fifteen years. Costs incurred during the preliminary project or the post-implementation/operation stages of the project are expensed as incurred. Capitalized computer software, included as a component of Ground property and equipment in the accompanying Consolidated Balance Sheet, net of accumulated depreciation, was $544 million and $378 million at December 31, 2016 , and 2015 , respectively. Computer software depreciation expense was $111 million , $106 million , and $122 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively, and is included as a component of Depreciation and amortization expense in the accompanying Consolidated Statement of Income. |
Income taxes | Income Taxes The Company accounts for deferred income taxes utilizing an asset and liability method, whereby deferred tax assets and liabilities are recognized based on the tax effect of temporary differences between the financial statements and the tax basis of assets and liabilities, as measured by current enacted tax rates. The Company also evaluates the need for a valuation allowance to reduce deferred tax assets to estimated recoverable amounts. See "Basis of Presentation" for further information on current presentation of deferred income taxes. The Company’s policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of income before income taxes. Penalties are recorded in Other (gains) losses, net, and interest paid or received is recorded in Interest expense or Interest income, respectively, in the Consolidated Statement of Income. Amounts recorded for penalties and interest related to uncertain tax positions were immaterial for all years presented. |
Concentration risk | Concentration Risk Approximately 83 percent of the Company’s full-time equivalent Employees are unionized and are covered by collective-bargaining agreements. A small percentage of the Company's unionized Employees, including its Mechanics, Material Specialists, and Facilities Maintenance Technicians, are in discussions on labor agreements. These Employee groups represent approximately five percent of the Company’s full-time equivalent Employees as of December 31, 2016. The Company attempts to minimize its concentration risk with regards to its cash, cash equivalents, and its investment portfolio. This is accomplished by diversifying and limiting amounts among different counterparties, the type of investment, and the amount invested in any individual security or money market fund. To manage risk associated with financial derivative instruments held, the Company selects and will periodically review counterparties based on credit ratings, limits its exposure to a single counterparty, and monitors the market position of the program and its relative market position with each counterparty. The Company also has agreements with counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount or credit ratings fall below certain levels. Collateral deposits provided to or held from counterparties serve to decrease, but not totally eliminate, the credit risk associated with the Company’s hedging program. See Note 10 for further information. As of December 31, 2016 , the Company operated an all-Boeing fleet, all of which are variations of the Boeing 737. If the Company were unable to acquire additional aircraft or associated aircraft parts from Boeing, or Boeing were unable or unwilling to make timely deliveries of aircraft or to provide adequate support for its products, the Company’s operations would be materially adversely impacted. In addition, the Company would be materially adversely impacted in the event of a mechanical or regulatory issue associated with the Boeing 737 aircraft type, whether as a result of downtime for part or all of the Company’s fleet, increased maintenance costs, or because of a negative perception by the flying public. The Company is also dependent on sole suppliers for aircraft engines and certain other aircraft parts and would, therefore, also be materially adversely impacted in the event of the unavailability of, or a mechanical or regulatory issue associated with, engines and other parts. The Company has historically entered into agreements with some of its co-brand, payment, and loyalty partners that contain exclusivity aspects which place certain confidential restrictions on the Company from entering into certain arrangements with other payment and loyalty partners. These arrangements generally extend for the terms of the agreements, none of which currently extend beyond May 2022 . The Company believes the financial benefits generated by the exclusivity aspects of these arrangements outweigh the risks involved with such agreements. |
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 Consolidated Balance Sheet are those in which the Company pays or receives cash for transactions with the same counterparty 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 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 Ineffectiveness is inherent in hedging jet fuel with derivative positions based in other crude oil related commodities. Due to the volatility in markets for crude oil and related products, the Company is unable to predict the amount of ineffectiveness each period, including the loss of hedge accounting, which could be determined on a derivative by derivative basis or in the aggregate for a specific commodity. This may result, and has resulted, in increased volatility in the Company’s financial results. Factors that have and may continue to lead to ineffectiveness and unrealized gains and losses on derivative contracts include: significant fluctuation in energy prices, the number of derivative positions the Company holds, significant weather events affecting refinery capacity and the production of refined products, and the volatility of the different types of products the Company uses in hedging. However, even though derivatives may not qualify for hedge accounting, the Company continues to hold the instruments as management believes derivative instruments continue to afford the Company the opportunity to stabilize jet fuel costs. Accounting pronouncements pertaining to derivative instruments and hedging are complex with stringent requirements, including the documentation of a Company hedging strategy, statistical analysis to qualify a commodity for hedge accounting both on a historical and a prospective basis, and strict contemporaneous documentation that is required at the time each hedge is designated by the Company. The Company also examines the effectiveness of each individual hedge and its entire hedging program on a quarterly basis utilizing statistical analysis. This analysis involves utilizing regression and other statistical analyses that compare changes in the price of jet fuel to changes in the prices of the commodities used for hedging purposes 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 12 . The Company’s results are subject to the possibility that periodic changes will not be effective, as defined, or that the derivatives will no longer qualify for hedge accounting. Ineffectiveness results when the change in the fair value of the derivative instrument exceeds the change in the value of the Company’s expected future cash outlay to purchase and consume jet fuel. 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 Consolidated Statement of 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 Consolidated Statement of 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. When the Company has sold derivative positions in order to effectively “close” or offset a derivative already held as part of its fuel derivative instrument portfolio, any subsequent changes in fair value of those positions are marked to market through earnings. Likewise, any changes in fair value of those positions that were offset by entering into the sold positions and were de-designated as hedges are concurrently marked to market through earnings. However, any changes in value related to hedges that were deferred as part of AOCI while designated as a hedge would remain until the originally forecasted transaction occurs. 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 2014 , 2015 , or 2016 . 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. Several of the Company's interest rate swap agreements 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 that do not qualify for the "shortcut" method of accounting, ineffectiveness is required to be measured at each reporting period |
Compensation Related Costs | A portion of the Company’s granted options qualify as incentive stock options for income tax purposes. As such, a tax benefit is not recorded at the time the compensation cost related to the options is recorded for book purposes due to the fact that an incentive stock option does not ordinarily result in a tax benefit unless there is a disqualifying disposition. Grants of non-qualified stock options and RSUs result in the creation of a deferred tax asset, which is a temporary difference, until the time that the option is exercised or the RSU vests. With the issuance of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, all excess tax benefits and tax deficiencies are recorded through the income statement. Due to the treatment of incentive stock options, non-qualified stock options, and RSUs for tax purposes, the Company’s effective tax rate from year to year is subject to variability. |
Employee Retirement Plans | Unrecognized prior service cost is expensed using a straight-line amortization of the cost over the average future service of Employees expected to receive benefits under the plans. Actuarial gains are amortized utilizing the minimum amortization method. The following actuarial assumptions were used to account for the Company’s postretirement benefit plans at December 31, 2016 , 2015 , and 2014 : 2016 2015 2014 Weighted-average discount rate 4.25 % 4.50 % 4.10 % Assumed healthcare cost trend rate (1) 7.08 % 7.08 % 6.88 % (1) The assumed healthcare cost trend rate is assumed to remain at 7.08% for 2017 , then decline gradually to 5.19% by 2027 and remain level thereafter. The assumed healthcare cost trend rates have a significant effect on the amounts reported for the consolidated postretirement plans. A one percent change in all healthcare cost trend rates used in measuring the APBO at December 31, 2016 , would have the following effects: (in millions) 1% increase 1% decrease Increase (decrease) in total service and interest costs $ 4 $ (3 ) Increase (decrease) in the APBO $ 36 $ (31 ) The selection of a discount rate is made annually and is selected by the Company based upon comparison of the expected future cash flows associated with the Company’s future payments under its consolidated postretirement obligations to a yield curve created using high quality bonds that closely match those expected future cash flows. This rate decreased during 2016 due to market conditions. The assumed healthcare trend rate is also reviewed at least annually and is determined based upon both historical experience with the Company’s healthcare benefits paid and expectations of how those trends may or may not change in future years. |

[1] | During second quarter 2016, the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, with an effective date as of January 1, 2016. The prospective method of adoption of this standard resulted in the recognition of $2 million of excess tax benefits to the Company's income tax provision for the six months ended June 30, 2016, but which were related to first quarter 2016. For this presentation and in future periods in which first quarter 2016 results are reported, these amounts are reflected in the appropriate period. The adoption had no impact to net income per share amounts. See Note 2 for further information. | |||||||||||||||||||

The impact of this change resulted in an increase to Operating revenue during first quarter 2016 of approximately $115 million and increased Basic and Diluted net income per share by approximately $.10 and $.09, respectively. The impact of this change resulted in an increase to Operating revenue during second quarter 2016 of approximately $137 million, and increased Basic and Diluted net income per share by approximately $.12 and $.11, respectively.

[1] | Includes the impact of the Agreement with Chase and the resulting required change in accounting methodology. The impact of this change during third quarter and fourth quarter 2015 resulted in increases to Operating revenue of approximately $303 million and $124 million, respectively, and increased Basic and Diluted net income per share by approximately $.24 in third quarter 2015 and by approximately $.10 in fourth quarter 2015. The impact of this change resulted in an increase to Operating revenue during first quarter 2016 of approximately $115 million and increased Basic and Diluted net income per share by approximately $.10 and $.09, respectively. The impact of this change resulted in an increase to Operating revenue during second quarter 2016 of approximately $137 million, and increased Basic and Diluted net income per share by approximately $.12 and $.11, respectively. See Note 1 for further detail. | ||||||||||||||||||
[2] | During second quarter 2016, the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, with an effective date as of January 1, 2016. The prospective method of adoption of this standard resulted in the recognition of $2 million of excess tax benefits to the Company's income tax provision for the six months ended June 30, 2016, but which were related to first quarter 2016. For this presentation and in future periods in which first quarter 2016 results are reported, these amounts are reflected in the appropriate period. The adoption had no impact to net income per share amounts. See Note 2 for further information. |
