Organization Basis of Presentation and Summary of Significant Accounting Policies [Line Items] |
Basis of Presentation | Basis of Presentation American Airlines Group Inc. (we, us, our and similar terms, or AAG), a Delaware corporation, is a holding company whose primary business activity is the operation of a major network air carrier, providing scheduled air transportation for passengers and cargo through its mainline operating subsidiary, American Airlines, Inc. (American) and its wholly-owned regional airline subsidiaries, Envoy Aviation Group Inc., PSA Airlines, Inc. (PSA) and Piedmont Airlines, Inc. (Piedmont), that operate under the brand American Eagle. All significant intercompany transactions have been eliminated. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, the loyalty program, deferred tax assets, as well as pension and retiree medical and other postretirement benefits.
Recent Accounting Pronouncements | Recent Accounting Pronouncements ASU 2023-07: Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures This standard improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. We are currently evaluating how the adoption of this standard will impact our reportable segment disclosures. ASU 2023-09: Income Taxes (Topic 740) Improvements to Income Tax Disclosures This standard enhances transparency of income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information, as well as improvements to the effectiveness and comparability of other income tax disclosures. The amendments in this update are effective for annual periods beginning after December 15, 2024, and early adoption is permitted. We are currently evaluating how the adoption of this standard will impact our income tax disclosures.
Investments | Investments Short-term investments primarily include debt securities and are classified as available-for-sale and stated at fair value. Realized gains and losses are recorded as interest income in nonoperating expense, net on our consolidated statements of operations. Unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on our consolidated balance sheets. For investments in an unrealized loss position, we determine whether a credit loss exists by considering information about the collectability of the instrument, current market conditions and reasonable and supportable forecasts of economic conditions. There have been no credit losses. Equity investments are accounted for under the equity method if we are able to exercise significant influence over an investee. Equity investments for which we do not have significant influence are recorded at fair value or at cost, if fair value is not readily determinable, with adjustments for observable changes in price or impairments (referred to as the measurement alternative). Our share of equity method investees’ financial results and changes in fair value are recorded in nonoperating other income (expense), net on the consolidated statements of operations.
Restricted Cash and Short-term Investments | Restricted Cash and Short-term Investments We have restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations and collateral associated with the AAdvantage Financing.
Accounts Receivable, Net | Accounts Receivable, Net Accounts receivable primarily consist of amounts due from credit card processing companies for tickets sold to individual passengers, amounts due from airline and non-airline business partners, including our co-branded credit card partners and cargo customers. Receivables from ticket sales are short-term, mostly settled within seven days after sale. Receivables from our business partners are typically settled within 30 days. All accounts receivable are reported net of an allowance for credit losses, which was not material as of December 31, 2023 and 2022. We consider past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.
Aircraft Fuel, Spare Parts and Supplies, Net | Aircraft Fuel, Spare Parts and Supplies, Net Aircraft fuel is recorded on a first-in, first-out basis. Spare parts and supplies are recorded at average costs less an allowance for obsolescence, which is recognized over the weighted average remaining useful life of the related fleet. We also provide an allowance for spare parts and supplies identified as excess or obsolete to reduce the carrying cost to the lower of cost or net realizable value. Aircraft fuel, spare parts and supplies are expensed when used.
Operating Property and Equipment | Operating Property and Equipment Operating property and equipment is recorded at cost and depreciated or amortized to residual values over the asset’s estimated useful life or the lease term, whichever is less, using the straight-line method. Residual values for aircraft, engines and related rotable parts are generally 5% to 10% of original cost. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated or amortized over the estimated useful life of the asset or the lease term, whichever is less. The estimated useful lives for the principal property and equipment classifications are as follows:
Principal Property and Equipment Classification | Estimated Useful Life
Aircraft, engines and related rotable parts | 20 – 30 years
Buildings and improvements | 5 – 30 years
Furniture, fixtures and other equipment | 3 – 15 years
Capitalized software | 5 – 10 years
Impairment | We assess impairment of operating property and equipment when events and circumstances indicate that the assets may be impaired. An impairment of an asset or group of assets exists only when the sum of the estimated undiscounted cash flows expected to be generated directly by the assets are less than the carrying value of the assets. We group assets principally by fleet-type when estimating future cash flows, which is generally the lowest level for which identifiable cash flows exist. Estimates of future cash flows are based on historical results adjusted to reflect management’s best estimate of future market and operating conditions, including our current fleet plan. If such assets are impaired, the impairment charge recognized is the amount by which the carrying value of the assets exceed their fair value. Fair value reflects management’s best estimate including inputs from published pricing guides and bids from third parties as well as contracted sales agreements when applicable.
Leases | Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (ROU) assets, current operating lease liabilities and noncurrent operating lease liabilities on our consolidated balance sheets. Finance leases are included in property and equipment, current maturities of long-term debt and finance leases and long-term debt and finance leases, net of current maturities, on our consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. We give consideration to our recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates. Our lease term includes options to extend the lease when it is reasonably certain that we will exercise that option. Leases with a term of 12 months or less are not recorded on our consolidated balance sheets. Under certain of our capacity purchase agreements with third-party regional carriers, we do not own the underlying aircraft. However, since we control the marketing, scheduling, ticketing, pricing and seat inventories of these aircraft and therefore control the asset, the aircraft is deemed to be leased for accounting purposes. For these capacity purchase agreements, we account for the lease and non-lease components separately. The lease component consists of the aircraft and the non-lease components consist of services, such as the crew and maintenance. Where applicable, we allocate the consideration in the capacity purchase agreements to the lease and non-lease components using their estimated relative standalone prices. See Note 11(b) for additional information on our capacity purchase agreements. For real estate, we account for the lease and non-lease components as a single lease component.
Income Taxes | Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are recorded net as noncurrent deferred income taxes. We provide a valuation allowance for our deferred tax assets when it is more likely than not that some portion, or all of our deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our assessment of future profitability, including conditions which are beyond our control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. We have determined that positive factors outweigh negative factors in the determination of the realizability of our deferred tax assets.
Goodwill | Goodwill Goodwill represents the purchase price in excess of the fair value of the net assets acquired and liabilities assumed in connection with the 2013 merger with US Airways Group, Inc. (US Airways Group). We have one reporting unit. We assess goodwill for impairment annually or more frequently if events or circumstances indicate that the fair value of goodwill may be lower than the carrying value. Our annual assessment date is October 1. Goodwill is assessed for impairment by initially performing a qualitative assessment. If we determine that it is more likely than not that our goodwill may be impaired, we use a quantitative approach to assess the asset’s fair value and the amount of the impairment, if any.
Other Intangibles, Net | Other Intangibles, Net Intangible assets consist primarily of certain domestic airport slots and gate leasehold rights, customer relationships, marketing agreements, commercial agreements, international slots and route authorities and tradenames. Definite-Lived Intangible Assets Definite-lived intangible assets are originally recorded at their acquired fair values, subsequently amortized over their respective estimated useful lives and are assessed for impairment whenever events and circumstances indicate that the assets may be impaired. Certain domestic airport slots and airport gate leasehold rights are amortized on a straight-line basis over 25 years. Certain marketing agreements were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately 30 years. Customer relationships and tradenames are fully amortized. Indefinite-Lived Intangible Assets Indefinite-lived intangible assets include certain domestic airport slots, international slots and route authorities and our commercial agreement with GOL Linhas Aéreas Inteligentes S.A. (GOL). We assess indefinite-lived intangible assets for impairment annually or more frequently if events or circumstances indicate that the fair values of indefinite-lived intangible assets may be lower than their carrying values. Our annual assessment date is October 1. Indefinite-lived intangible assets are assessed for impairment by initially performing a qualitative assessment. If we determine that it is more likely than not that our indefinite-lived intangible assets may be impaired, we use a quantitative approach to assess the asset’s fair value and the amount of the impairment, if any.
Revenue Recognition | We attribute passenger revenue by geographic region based upon the origin and destination of each flight segment. Passenger Revenue We recognize all revenues generated from transportation on American and our regional flights operated under the brand name American Eagle, including associated baggage fees and other inflight services, as passenger revenue when transportation is provided. Ticket and other related sales for transportation that has not yet been provided are initially deferred and recorded as air traffic liability on our consolidated balance sheets. The air traffic liability principally represents tickets sold for future travel on American and partner airlines. The majority of tickets sold are nonrefundable. A small percentage of tickets, some of which are partially used tickets, expire unused. The estimate for tickets expected to expire unused is generally based on an analysis of our historical data and other current applicable factors such as policy changes. We have consistently applied this accounting method to estimate and recognize revenue from unused tickets at the date of travel. This estimate is periodically evaluated based on subsequent activity to validate its accuracy. Any adjustments resulting from periodic evaluations of the estimated air traffic liability are included in passenger revenue during the period in which the evaluations are completed. Various taxes and fees assessed on the sale of tickets to end customers are collected by us as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority. Loyalty Revenue We currently operate the loyalty program, AAdvantage. This program awards mileage credits to passengers who fly on American, any one world airline or other partner airlines, or by using the services of other program participants, such as our co-branded credit cards, and certain hotels and car rental companies. Mileage credits can be redeemed for travel on American and other participating partner airlines, as well as non-air travel awards such as hotels and rental cars. For mileage credits earned by AAdvantage program members, we apply the deferred revenue method. Mileage credits earned through travel For mileage credits earned through travel, we apply a relative selling price approach whereby the total amount collected from each passenger ticket sale is allocated between the air transportation and the mileage credits earned. The portion of each passenger ticket sale attributable to mileage credits earned is initially deferred and then recognized in passenger revenue when mileage credits are redeemed and transportation is provided. The estimated selling price of mileage credits is determined using an equivalent ticket value approach, which uses historical data, including award redemption patterns by geographic region and class of service, as well as similar cash fares as those used to settle award redemptions. The estimated selling price of mileage credits is adjusted for an estimate of mileage credits that will not be redeemed using a statistical model based on historical redemption patterns to develop an estimate of the likelihood of future redemption. Mileage credits sold to co-branded credit cards and other partners We sell mileage credits to participating airline partners and non-airline business partners, including our co-branded credit card partners, under contracts with remaining terms generally from one to six years as of December 31, 2023. Consideration received from the sale of mileage credits is variable and payment terms typically are within 30 days subsequent to the month of mileage sale. Sales of mileage credits to non-airline business partners are comprised of two components, transportation and marketing. We allocate the consideration received from these sales of mileage credits based on the relative selling price of each product or service delivered. Our most significant mileage credit partner agreements are our co-branded credit card agreements with Citi and Barclaycard US. We identified two revenue elements in these co-branded credit card agreements: the transportation component and the marketing component. The transportation component represents the estimated selling price of future travel awards and is determined using the same equivalent ticket value approach described above. The portion of each mileage credit sold attributable to transportation is initially deferred and then recognized in passenger revenue when mileage credits are redeemed and transportation is provided. The marketing component includes the use of intellectual property, including the American brand and access to loyalty program member lists, which is the predominant element in these agreements, as well as advertising and other travel-related benefits. We recognize the marketing component in other revenue in the period of the mileage credit sale following the sales-based royalty method. For the portion of our outstanding mileage credits that we estimate will not be redeemed, we recognize the associated value proportionally as the remaining mileage credits are redeemed. Our estimates use a statistical model based on historical redemption patterns to develop an estimate of the likelihood of future redemption. Cargo Revenue Cargo revenue is recognized when we provide the transportation. Other Revenue Other revenue includes revenue associated with our loyalty program, which is comprised principally of the marketing component of mileage credit sales to co-branded credit card and other partners and other marketing related payments. The accounting and recognition for the loyalty program marketing services are discussed above in “Loyalty Revenue.” The remaining amounts included within other revenue relate to airport clubs, other commission revenue, advertising and vacation-related services. Contract Balances Our significant contract liabilities are comprised of (1) outstanding loyalty program mileage credits that may be redeemed for future travel and non-air travel awards, reported as loyalty program liability on our consolidated balance sheets and (2) ticket sales for transportation that has not yet been provided, reported as air traffic liability on our consolidated balance sheets.
| December 31,
| 2023 |  | 2022
| (In millions)
Loyalty program liability | $ | 9,327 |  |  | $ | 9,145 |
Air traffic liability | 6,200 |  |  | 6,745 |
Total | $ | 15,527 |  |  | $ | 15,890 |
The balance of the loyalty program liability fluctuates based on seasonal patterns, which impact the volume of mileage credits issued through travel or sold to co-branded credit card and other partners (deferral of revenue) and mileage credits redeemed (recognition of revenue). Changes in loyalty program liability are as follows (in millions):
Balance at December 31, 2022 | $ | 9,145 |
Deferral of revenue | 3,810 |
Recognition of revenue (1) | (3,628) |
Balance at December 31, 2023 (2) | $ | 9,327 |
(1)Principally relates to revenue recognized from the redemption of mileage credits for both air and non-air travel awards. Mileage credits are combined in one homogenous pool and are not separately identifiable. As such, the revenue is comprised of mileage credits that were part of the loyalty program deferred revenue balance at the beginning of the period, as well as mileage credits that were issued during the period. (2)Mileage credits can be redeemed at any time and generally do not expire as long as that AAdvantage member has any type of qualifying activity at least every 24 months or if the AAdvantage member is the primary holder of a co-branded credit card. As of December 31, 2023, our current loyalty program liability was $3.5 billion and represents our current estimate of revenue expected to be recognized in the next 12 months based on historical trends, with the balance reflected in long-term loyalty program liability expected to be recognized as revenue in periods thereafter. The air traffic liability principally represents tickets sold for future travel on American and partner airlines. The balance in our air traffic liability also fluctuates with seasonal travel patterns. The contract duration of passenger tickets is generally one year. Accordingly, any revenue associated with tickets sold for future travel will be recognized within 12 months. For 2023, $5.3 billion of revenue was recognized in passenger revenue that was included in our air traffic liability at December 31, 2022.
Maintenance, Materials and Repairs | Maintenance, Materials and Repairs Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under certain power-by-the-hour maintenance agreements, which are charged to operating expense based on contractual terms when an obligation exists.
Selling Expenses | Selling ExpensesSelling expenses include credit card fees, commissions, third party distribution channel fees and advertising. Selling expenses associated with passenger revenue are expensed when the transportation or service is provided. Advertising costs are expensed as incurred.
Share-based Compensation | Share-based Compensation We account for our share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The majority of our stock awards are time vested restricted stock units, and the fair value of such awards is based on the market price of the underlying shares of AAG common stock on the date of grant. See Note 14 for further discussion of share-based compensation.
Foreign Currency Gains and Losses | Foreign Currency Gains and LossesForeign currency gains and losses are recorded as part of other income (expense), net within total nonoperating expense, net on our consolidated statements of operations.
Other Operating Expenses | Other Operating Expenses Other operating expenses includes costs associated with onboard food and catering, crew travel, ground and cargo handling, passenger accommodation, international navigation fees, aircraft cleaning, airport lounge operations and certain general and administrative expenses.
Regional Expenses | Regional Expenses Our regional carriers provide scheduled air transportation under the brand name “American Eagle.” The American Eagle carriers include our wholly-owned regional carriers as well as third-party regional carriers. Our regional carrier arrangements are in the form of capacity purchase agreements with our third-party regional partners and similar arrangements with our wholly-owned regional affiliates. Expenses associated with American Eagle operations are classified as regional expenses on the consolidated statements of operations.
American Airlines, Inc. |
Organization Basis of Presentation and Summary of Significant Accounting Policies [Line Items] |
Basis of Presentation | Basis of Presentation American Airlines, Inc. (American) is a Delaware corporation whose primary business activity is the operation of a major network air carrier, providing scheduled air transportation for passengers and cargo. American is the principal wholly-owned subsidiary of American Airlines Group Inc. (AAG), which owns all of American’s outstanding common stock, par value $1.00 per share. All significant intercompany transactions have been eliminated. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, the loyalty program, deferred tax assets, as well as pension and retiree medical and other postretirement benefits.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Accounting Standards Update (ASU) 2023-07: Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures This standard improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. American is currently evaluating how the adoption of this standard will impact its reportable segment disclosures. ASU 2023-09: Income Taxes (Topic 740) Improvements to Income Tax Disclosures This standard enhances transparency of income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information, as well as improvements to the effectiveness and comparability of other income tax disclosures. The amendments in this update are effective for annual periods beginning after December 15, 2024, and early adoption is permitted. American is currently evaluating how the adoption of this standard will impact its income tax disclosures.
Investments | Investments Short-term investments primarily include debt securities and are classified as available-for-sale and stated at fair value. Realized gains and losses are recorded as interest income in nonoperating expense, net on American’s consolidated statements of operations. Unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on American’s consolidated balance sheets. For investments in an unrealized loss position, American determines whether a credit loss exists by considering information about the collectability of the instrument, current market conditions and reasonable and supportable forecasts of economic conditions. There have been no credit losses. Equity investments are accounted for under the equity method if American is able to exercise significant influence over an investee. Equity investments for which American does not have significant influence are recorded at fair value or at cost, if fair value is not readily determinable, with adjustments for observable changes in price or impairments (referred to as the measurement alternative). American’s share of equity method investees’ financial results and changes in fair value are recorded in nonoperating other income (expense), net on the consolidated statements of operations.
Restricted Cash and Short-term Investments | Restricted Cash and Short-term Investments American has restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations and collateral associated with the AAdvantage Financing.
Accounts Receivable, Net | Accounts Receivable, Net Accounts receivable primarily consist of amounts due from credit card processing companies for tickets sold to individual passengers, amounts due from airline and non-airline business partners, including American’s co-branded credit card partners and cargo customers. Receivables from ticket sales are short-term, mostly settled within seven days after sale. Receivables from American’s business partners are typically settled within 30 days. All accounts receivable are reported net of an allowance for credit losses, which was not material as of December 31, 2023 and 2022. American considers past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.
Aircraft Fuel, Spare Parts and Supplies, Net | Aircraft Fuel, Spare Parts and Supplies, Net Aircraft fuel is recorded on a first-in, first-out basis. Spare parts and supplies are recorded at average costs less an allowance for obsolescence, which is recognized over the weighted average remaining useful life of the related fleet. American also provides an allowance for spare parts and supplies identified as excess or obsolete to reduce the carrying cost to the lower of cost or net realizable value. Aircraft fuel, spare parts and supplies are expensed when used.
Operating Property and Equipment | Operating Property and Equipment Operating property and equipment is recorded at cost and depreciated or amortized to residual values over the asset’s estimated useful life or the lease term, whichever is less, using the straight-line method. Residual values for aircraft, engines and related rotable parts are generally 5% to 10% of original cost. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated or amortized over the estimated useful life of the asset or the lease term, whichever is less. The estimated useful lives for the principal property and equipment classifications are as follows:
Principal Property and Equipment Classification | Estimated Useful Life
Aircraft, engines and related rotable parts | 20 – 30 years
Buildings and improvements | 5 – 30 years
Furniture, fixtures and other equipment | 3 – 15 years
Capitalized software | 5 – 10 years
Impairment | American assesses impairment of operating property and equipment when events and circumstances indicate that the assets may be impaired. An impairment of an asset or group of assets exists only when the sum of the estimated undiscounted cash flows expected to be generated directly by the assets are less than the carrying value of the assets. American groups assets principally by fleet-type when estimating future cash flows, which is generally the lowest level for which identifiable cash flows exist. Estimates of future cash flows are based on historical results adjusted to reflect management’s best estimate of future market and operating conditions, including American’s current fleet plan. If such assets are impaired, the impairment charge recognized is the amount by which the carrying value of the assets exceed their fair value. Fair value reflects management’s best estimate including inputs from published pricing guides and bids from third parties as well as contracted sales agreements when applicable.
Leases | Leases American determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (ROU) assets, current operating lease liabilities and noncurrent operating lease liabilities on American’s consolidated balance sheets. Finance leases are included in property and equipment, current maturities of long-term debt and finance leases and long-term debt and finance leases, net of current maturities, on American’s consolidated balance sheets. ROU assets represent American’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. American uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. American gives consideration to its recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. American’s lease term includes options to extend the lease when it is reasonably certain that it will exercise that option. Leases with a term of 12 months or less are not recorded on its consolidated balance sheets. Under certain of American’s capacity purchase agreements with third-party regional carriers, American does not own the underlying aircraft. However, since American controls the marketing, scheduling, ticketing, pricing and seat inventories of these aircraft and therefore control the asset, the aircraft is deemed to be leased for accounting purposes. For these capacity purchase agreements, American accounts for the lease and non-lease components separately. The lease component consists of the aircraft and the non-lease components consist of services, such as the crew and maintenance. Where applicable, American allocates the consideration in the capacity purchase agreements to the lease and non-lease components using their estimated relative standalone prices. See Note 10(b) for additional information on its capacity purchase agreements. For real estate, American accounts for the lease and non-lease components as a single lease component.
Income Taxes | Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are recorded net as noncurrent deferred income taxes. American provides a valuation allowance for its deferred tax assets when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. American considers all available positive and negative evidence and makes certain assumptions in evaluating the realizability of its deferred tax assets. Many factors are considered that impact American’s assessment of future profitability, including conditions which are beyond its control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. American has determined that positive factors outweigh negative factors in the determination of the realizability of its deferred tax assets.
Goodwill | Goodwill Goodwill represents the purchase price in excess of the fair value of the net assets acquired and liabilities assumed in connection with the 2013 merger with US Airways Group, Inc. (US Airways Group). American has one reporting unit. American assesses goodwill for impairment annually or more frequently if events or circumstances indicate that the fair value of goodwill may be lower than the carrying value. American’s annual assessment date is October 1. Goodwill is assessed for impairment by initially performing a qualitative assessment. If American determines that it is more likely than not that its goodwill may be impaired, it uses a quantitative approach to assess the asset’s fair value and the amount of the impairment, if any. Based upon American’s annual assessment, there was no goodwill impairment in 2023. The carrying value of American’s goodwill on its consolidated balance sheets was $4.1 billion as of December 31, 2023 and 2022.
Other Intangibles, Net | Other Intangibles, Net Intangible assets consist primarily of certain domestic airport slots and gate leasehold rights, customer relationships, marketing agreements, commercial agreements, international slots and route authorities and tradenames. Definite-Lived Intangible Assets Definite-lived intangible assets are originally recorded at their acquired fair values, subsequently amortized over their respective estimated useful lives and are assessed for impairment whenever events and circumstances indicate that the assets may be impaired. Certain domestic airport slots and airport gate leasehold rights are amortized on a straight-line basis over 25 years. Certain marketing agreements were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately 30 years. Customer relationships and tradenames are fully amortized. Indefinite-Lived Intangible Assets Indefinite-lived intangible assets include certain domestic airport slots, international slots and route authorities and American’s commercial agreement with GOL Linhas Aéreas Inteligentes S.A. (GOL). American assesses indefinite-lived intangible assets for impairment annually or more frequently if events or circumstances indicate that the fair values of indefinite-lived intangible assets may be lower than their carrying values. American’s annual assessment date is October 1. Indefinite-lived intangible assets are assessed for impairment by initially performing a qualitative assessment. If American determines that it is more likely than not that its indefinite-lived intangible assets may be impaired, American uses a quantitative approach to assess the asset’s fair value and the amount of the impairment, if any.
Revenue Recognition | American attributes passenger revenue by geographic region based upon the origin and destination of each flight segment. Passenger Revenue American recognizes all revenues generated from transportation on American and its regional flights operated under the brand name American Eagle, including associated baggage fees and other inflight services, as passenger revenue when transportation is provided. Ticket and other related sales for transportation that has not yet been provided are initially deferred and recorded as air traffic liability on American’s consolidated balance sheets.

These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority. Loyalty Revenue American currently operates the loyalty program, AAdvantage. This program awards mileage credits to passengers who fly on American, any one world airline or other partner airlines, or by using the services of other program participants, such as American’s co-branded credit cards, and certain hotels and car rental companies. Mileage credits can be redeemed for travel on American and other participating partner airlines, as well as non-air travel awards such as hotels and rental cars. For mileage credits earned by AAdvantage program members, American applies the deferred revenue method. Mileage credits earned through travel For mileage credits earned through travel, American applies a relative selling price approach whereby the total amount collected from each passenger ticket sale is allocated between the air transportation and the mileage credits earned. The portion of each passenger ticket sale attributable to mileage credits earned is initially deferred and then recognized in passenger revenue when mileage credits are redeemed and transportation is provided.

The estimated selling price of mileage credits is adjusted for an estimate of mileage credits that will not be redeemed using a statistical model based on historical redemption patterns to develop an estimate of the likelihood of future redemption. Mileage credits sold to co-branded credit cards and other partners American sells mileage credits to participating airline partners and non-airline business partners, including American’s co-branded credit card partners, under contracts with remaining terms generally from one to six years as of December 31, 2023. Consideration received from the sale of mileage credits is variable and payment terms typically are within 30 days subsequent to the month of mileage sale. Sales of mileage credits to non-airline business partners are comprised of two components, transportation and marketing. American allocates the consideration received from these sales of mileage credits based on the relative selling price of each product or service delivered. American’s most significant mileage credit partner agreements are its co-branded credit card agreements with Citi and Barclaycard US. American identified two revenue elements in these co-branded credit card agreements: the transportation component and the marketing component. The transportation component represents the estimated selling price of future travel awards and is determined using the same equivalent ticket value approach described above. The portion of each mileage credit sold attributable to transportation is initially deferred and then recognized in passenger revenue when mileage credits are redeemed and transportation is provided. The marketing component includes the use of intellectual property, including the American brand and access to loyalty program member lists, which is the predominant element in these agreements, as well as advertising and other travel-related benefits. American recognizes the marketing component in other revenue in the period of the mileage credit sale following the sales-based royalty method. For the portion of American’s outstanding mileage credits that it estimates will not be redeemed, American recognizes the associated value proportionally as the remaining mileage credits are redeemed. American’s estimates use a statistical model based on historical redemption patterns to develop an estimate of the likelihood of future redemption. Cargo Revenue Cargo revenue is recognized when American provides the transportation. Other Revenue Other revenue includes revenue associated with American’s loyalty program, which is comprised principally of the marketing component of mileage credit sales to co-branded credit card and other partners and other marketing related payments. The accounting and recognition for the loyalty program marketing services are discussed above in “Loyalty Revenue.” The remaining amounts included within other revenue relate to airport clubs, other commission revenue, advertising and vacation-related services. Contract Balances American’s significant contract liabilities are comprised of (1) outstanding loyalty program mileage credits that may be redeemed for future travel and non-air travel awards, reported as loyalty program liability on American’s consolidated balance sheets and (2) ticket sales for transportation that has not yet been provided, reported as air traffic liability on American’s consolidated balance sheets. The balance of the loyalty program liability fluctuates based on seasonal patterns, which impact the volume of mileage credits issued through travel or sold to co-branded credit card and other partners (deferral of revenue) and mileage credits redeemed (recognition of revenue). The air traffic liability principally represents tickets sold for future travel on American and partner airlines. The balance in American’s air traffic liability also fluctuates with seasonal travel patterns. The contract duration of passenger tickets is generally one year. Accordingly, any revenue associated with tickets sold for future travel will be recognized within 12 months. For 2023, $5.3 billion of revenue was recognized in passenger revenue that was included in American’s air traffic liability at December 31, 2022.
Maintenance, Materials and Repairs | Maintenance, Materials and Repairs Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under certain power-by-the-hour maintenance agreements, which are charged to operating expense based on contractual terms when an obligation exists.
Selling Expenses | Selling ExpensesSelling expenses include credit card fees, commissions, third party distribution channel fees and advertising. Selling expenses associated with passenger revenue are expensed when the transportation or service is provided. Advertising costs are expensed as incurred.
Share-based Compensation | Share-based Compensation American accounts for its share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The majority of American’s stock awards are time vested restricted stock units, and the fair value of such awards is based on the market price of the underlying shares of AAG common stock on the date of grant. See Note 13 for further discussion of share-based compensation.
Foreign Currency Gains and Losses | Foreign Currency Gains and LossesForeign currency gains and losses are recorded as part of other income (expense), net within total nonoperating expense, net on American’s consolidated statements of operations.
Other Operating Expenses | Other Operating Expenses Other operating expenses includes costs associated with onboard food and catering, crew travel, ground and cargo handling, passenger accommodation, international navigation fees, aircraft cleaning, airport lounge operations and certain general and administrative expenses.
Regional Expenses | Regional Expenses American's regional carriers provide scheduled air transportation under the brand name “American Eagle.” The American Eagle carriers include AAG's wholly-owned regional carriers as well as third-party regional carriers. American's regional carrier arrangements are in the form of capacity purchase agreements with its third-party regional partners and similar arrangements with AAG’s wholly-owned regional affiliates. Expenses associated with American Eagle operations are classified as regional expenses on the consolidated statements of operations.
