Basis Of Presentation [Abstract]
Basis of Presentation	1. Basis of Presentation Our consolidated financial statements include the accounts of the holding company, Atlas Air Worldwide Holdings, Inc. (“AAWW”), and its consolidated subsidiaries. AAWW is the parent company of our principal operating subsidiary, Atlas Air, Inc. (“Atlas”), and several subsidiaries related to our dry leasing services (collectively referred to as “Titan”). AAWW also has a 51 % equity interest and 75 % voting interest in Polar Air Cargo Worldwide, Inc. (“Polar”). We record our share of Polar’s results under the equity method of accounting. Polar is a variable interest entity that we do not consolidate because we are not the primary beneficiary and we generally do not have any financial exposure to fund debt obligations or operating losses of Polar (see Note 3 for further discussion). The terms “we,” “us,” “our,” and the “Company” mean AAWW and all entities included in its consolidated financial statements. We provide outsourced aircraft and aviation operating services throughout the world, serving Africa, Asia, Australia, Europe, the Middle East, North America and South America through: (i) contractual service arrangements, including those through which we provide aircraft to customers and value-added services, including crew, maintenance and insurance (“ACMI”), crew, maintenance and insurance, but not the aircraft (“CMI”) and cargo and passenger charter services (“Charter”); and (ii) dry leasing aircraft and engines (“Dry Leasing” or “Dry Lease”). The accompanying unaudited consolidated financial statements and related notes (the “Financial Statements”) have been prepared in accordance with the U.S. Securities and Exchange Commission (the “SEC”) requirements for quarterly reports on Form 10-Q, and consequently exclude certain disclosures normally included in audited consolidated financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Intercompany accounts and transactions have been eliminated. The Financial Statements should be read in conjunction with the audited consolidated financial statements and the notes included in the AAWW Annual Report on Form 10-K for the year ended December 31, 2021, which includes additional disclosures and a summary of our significant accounting policies. The December 31, 2021 balance sheet data was derived from that Annual Report. In our opinion, these Financial Statements include all adjustments, consisting of normal recurring items, considered necessary by management to fairly state the Company’s results of operations, financial position, and cash flows. Our quarterly results are subject to seasonal and other fluctuations, including fluctuations resulting from the global COVID-19 pandemic and the operating results for any quarter are therefore not necessarily indicative of results that may be otherwise expected for the entire year. Except for per share data, all dollar amounts are in thousands unless otherwise noted.

Summary of Significant Accounting Policies	Jun. 30, 2022
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Heavy Maintenance Except as described in the paragraph below, we account for heavy maintenance costs for airframes and engines using the direct expense method. Under this method, heavy maintenance costs are charged to expense upon induction, based on our best estimate of the costs after considering multiple factors, including historical costs, experience and information provided by third-party maintenance providers. These estimates may be subsequently adjusted for changes and the final determination of actual costs incurred. As of June 30, 2022 and December 31, 2021 , Accrued heavy maintenance was $ 72.3 million and $ 79.6 million, respectively. We account for heavy maintenance costs for airframes and engines used in our Dry Leasing segment and engines used on our 747-8F and 777-200 aircraft using the deferral method. Under this method, we defer the expense recognition of scheduled heavy maintenance events, which are amortized over the shorter of the estimated period until the next scheduled heavy maintenance event is required or remaining lease term. Amortization of deferred maintenance expense included in Depreciation and amortization was $ 12.2 million and $ 23.3 million for the three and six months ended June 30, 2022 , respectively. Amortization of deferred maintenance expense included in Depreciation and amortization was $ 12.3 million and $ 24.3 million for the three and six months ended June 30, 2021 , respectively. Deferred maintenance included within Deferred costs and other assets is as follows: Balance as of December 31, 2021 $ 180,675 Deferred maintenance costs 14,236 Special charge (1) ( 1,628 ) Amortization of deferred maintenance ( 23,325 ) Balance as of June 30, 2022 $ 169,958 (1) See Note 6 for further discussion. Property and Equipment Committed capital expenditures are expected to be $ 501.8 million for the remainder of 2022 and $ 359.7 million in 2023. These expenditures include delivery payments for our January 2021 agreement to purchase four 747-8F aircraft from The Boeing Company (“Boeing”), the first of these aircraft was delivered during the second quarter of 2022 and the remaining three are expected to be delivered throughout 2022. These amounts also include pre-delivery and delivery payments for our December 2021 agreement to purchase four new 777-200LRF aircraft from Boeing, the first of these aircraft is expected to be delivered late in the fourth quarter of 2022 and the remaining three throughout 2023. In addition, the amounts include other agreements to acquire spare engines. Payroll Support Program under the CARES Act In May 2020, two subsidiaries of the Company, Atlas and Southern Air, Inc. (“Southern Air”, and together with Atlas, the “PSP Recipients”) entered into an agreement with the U.S. Treasury (the "PSP Agreement") with respect to payroll support funding available to cargo carriers under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). AAWW also entered into a Warrant Agreement (the “Warrant Agreement”) with the U.S. Treasury, and AAWW issued a senior unsecured promissory note to the U.S. Treasury (the “Promissory Note”), with the PSP Recipients as guarantor. In connection with the payroll support funding received in 2020 under the PSP Agreement, we issued warrants to the U.S. Treasury to acquire up to 625,452 shares of our common stock. The warrants will expire in 2025 on the fifth anniversary of the issue date of each warrant. As of June 30, 2022 , no portion of the warrants have been exercised. We initially recognized deferred grant income within Accrued liabilities for the difference between the payroll support funding received in 2020 under the PSP Agreement and the amounts recorded for the Promissory Note and the Warrant Agreement. All grant income has been subsequently recognized within Other (income) expense, net in the consolidated statement of operations on a pro-rata basis over the periods that the qualifying employee wages, salaries and benefits were paid. During the six months ended June 30, 2021 , we recognized the remaining $ 40.9 million of deferred grant income within Other (income) expense, net in the consolidated statement of operations. Recent Accounting Pronouncement Adopted in 2022 In August 2020, the Financial Accounting Standards Board amended its accounting guidance for certain financial instruments with characteristics of liabilities and equity, including convertible debt instruments. For convertible debt with a cash conversion feature, the amended guidance removes the accounting model to separately account for the liability and equity components, which resulted in the amortization of a debt discount to interest expense. Under this amended guidance, such convertible debt is accounted for as a single debt instrument with no amortization of a debt discount, unless certain other conditions are met. The amended guidance also requires the use of the if-converted method when calculating the dilutive impact of convertible debt on earnings per share. Effective January 1, 2022, we adopted the amended guidance using the modified retrospective approach, under which the guidance was applied only to the most current period presented. On January 1, 2022, we recorded an increase of $ 31.0 million to the carrying value of our convertible notes, a reduction of $ 6.9 million to deferred tax liabilities, a reduction of $ 92.6 million to Additional paid-in capital and an increase of $ 68.5 million to Retained earnings for the cumulative effect of adoption.

Related Party Transactions [Abstract]
Related Parties	3. Related Parties Polar AAWW has a 51 % equity interest and 75 % voting interest in Polar. DHL Network Operations (USA), Inc. (“DHL”), a subsidiary of Deutsche Post AG, holds a 49 % equity interest and a 25 % voting interest in Polar. Polar is a variable interest entity that we do not consolidate because we are not the primary beneficiary as the risks associated with the direct costs of operation are with DHL. Under a 20-year blocked space agreement, which began in 2008, Polar provides air cargo capacity to DHL. Atlas has several agreements with Polar to provide ACMI, CMI, Dry Leasing, administrative, sales and ground support services to one another.

Warrants And Rights Note Disclosure [Abstract]
Amazon	4. Amazon In May 2016, we entered into certain agreements with Amazon.com, Inc. and its subsidiary, Amazon Fulfillment Services, Inc., (collectively “Amazon”), which involve, among other things, CMI operation of up to 20 Boeing 767-300 freighter aircraft for Amazon by Atlas, as well as Dry Leasing by Titan. The Dry Leases have a term of ten years from the commencement of each agreement, while the CMI operations are for seven years from the commencement of each agreement (with an option for Amazon to extend the term to ten years ). As of June 30, 2022, 19 767-300 freighters were in Dry Lease service, of which 17 were operating in CMI service. In conjunction with the agreements entered into in May 2016, we granted Amazon a warrant providing the right to acquire up to 20% of our outstanding common shares, as of the date of the agreements , after giving effect to the issuance of shares pursuant to the warrants, at an exercise price of $ 37.34 per share, as adjusted (“Warrant A”). All 7.5 million shares, as adjusted, vested in full and have been exercised. The agreements entered into in May 2016 also provided incentives for future growth of the relationship with Amazon. In that regard, we granted Amazon a warrant to acquire up to an additional 10 % of our outstanding common shares, as of the date of the agreements , after giving effect to the issuance of shares pursuant to the warrants, for an exercise price of $ 37.34 per share, as adjusted (“Warrant B”). This warrant to purchase 3.77 million shares, as adjusted, will vest in increments of 37,660 shares, as adjusted, each time Amazon has paid $ 4.2 million of revenue to us, up to a total of $ 420.0 million, for incremental business beyond the original 20 767-300 freighters. As of June 30, 2022 , 1,280,440 shares, as adjusted, of Warrant B have vested, of which 715,540 shares remain unexercised. Warrant B will expire if not exercised in accordance with its terms by May 4, 2023 . In March 2019, we amended the agreements entered into in 2016 with Amazon, pursuant to which we began providing CMI services using Boeing 737-800 freighter aircraft provided by Amazon. The 737-800 CMI operations are for a term of seven years from the commencement of each agreement (with an option for Amazon to extend the term to ten years ). As of June 30, 2022, eight 737-800 freighter aircraft were operating in CMI service. In connection with the amended agreements, we granted Amazon a warrant to acquire up to an additional 9.9 % of our outstanding common shares, as of the date of the agreements , after giving effect to the issuance of shares pursuant to the warrant, for an exercise price of $ 52.67 per share, as adjusted (“Warrant C”). Only if Warrant B vests in full, this warrant to purchase 6.66 million shares, as adjusted, would vest in increments of 45,623 shares, as adjusted, each time Amazon has paid $ 6.9 million of revenue to us, up to a total of $ 1.0 billion, for incremental business beyond Warrant A and Warrant B. As of June 30, 2022 , no portion of Warrant C has vested. Warrant C will expire if not exercised in accordance with its terms by March 27, 2026 . Further, in the event that Warrant B does not vest in full on or prior to its May 4, 2023 expiration, then Warrant C will no longer be exercisable by Amazon as of that date. While Amazon would be entitled to vote the shares it owns up to 14.9 % of our outstanding common shares, in its discretion, it would be required to vote any shares it owns in excess of 14.9 % of our outstanding common shares in accordance with the recommendation of our board of directors. We amortized $ 9.9 million and $ 19.9 million of the customer incentive asset as a reduction of Operating Revenue for the three and six months ended June 30, 2022 , respectively. We amortized $ 11.4 million and $ 21.9 million of the customer incentive asset as a reduction of Operating Revenue for the three and six months ended June 30, 2021, respectively.

Debt

Debt	Jun. 30, 2022
Debt Disclosure [Abstract]
Debt	7. Debt Term Loans In May 2022, we borrowed $ 140.0 million for the delivery of one 747-8F aircraft under a twelve-year term loan due in May 2034 . The term loan is secured by a mortgage against one 747-8F aircraft and has a fixed interest rate of 4.17 % with principal and interest payable quarterly. The term loan is subject to customary fees, covenants and events of default. Convertible Notes In June 2015, we issued $ 224.5 million aggregate principal amount of convertible senior notes with 2.25 % coupon (the “2015 Convertible Notes”) in an underwritten public offering. We used the majority of the net proceeds to refinance debt related to 747-400 freighter aircraft with an average coupon of 8.1 %. In connection with the offering of the 2015 Convertible Notes, we purchased convertible note hedges whereby we had the right to receive a certain number of shares of our common stock at a fixed price per share. In addition, we sold warrants to the option counterparties whereby the holders of the warrants have the option to purchase a certain number of shares of our common stock at a fixed price per share. On June 1, 2022, the 2015 Convertible Notes reached maturity and were settled in full. In the aggregate, we paid $ 210.4 million and issued 138,509 shares of common stock to those holders that elected to convert their outstanding notes and we paid $ 6.2 million to holders that did not elect to convert their outstanding notes. In connection with the settlement of the 2015 Convertible Notes, we exercised our rights under the convertible note hedge transactions with the counterparties on June 1, 2022 and received 25,957 shares of our common stock. In May 2017, we issued $ 289.0 million aggregate principal amount of convertible senior notes that mature on June 1, 2024 with a 1.88 % coupon (the “2017 Convertible Notes”) in an underwritten public offering. We used the majority of the net proceeds to repay our then outstanding revolving credit facility. The 2017 Convertible Notes are senior unsecured obligations and accrue interest payable semiannually on June 1 and December 1 of each year. The 2017 Convertible Notes are due on their maturity date, unless earlier converted or repurchased pursuant to their respective terms. In connection with the offering of the 2017 Convertible Notes, we purchased convertible note hedges whereby we have the right to receive a certain number of shares of our common stock at a fixed price per share. In addition, we sold warrants to the option counterparties whereby the holders of the warrants have the option to purchase a certain number of shares of our common stock at a fixed price per share. Taken together, the purchase of the convertible note hedges and the sale of warrants are intended to offset economic dilution from the conversion of the 2017 Convertible Notes when the stock price is below the exercise price of the respective warrants and to effectively increase the overall conversion price from $ 61.08 to $ 92.20 per share for the 2017 Convertible Notes. On or after September 1, 2023 until the close of business on the second scheduled trading day immediately preceding the maturity date, a holder may convert all or a portion of its 2017 Convertible Notes. Upon conversion, the 2017 Convertible Notes will be settled, at our election, in cash, shares of our common stock, or a combination of cash and shares of our common stock. Prior to September 1, 2023, a holder may also convert under certain circumstances, including if the price of our common stock is greater than or equal to 130 % of the conversion price for at least 20 trading days during the 30 consecutive trading days ending on the last trading day of the quarter. Our current intent and policy is to settle conversions with a combination of cash and shares of common stock. The price of our common stock was greater than or equal to 130 % of the conversion price of the 2017 Convertible Notes for at least 20 trading days during the 30 consecutive trading days ending on the last trading day of the quarter ended March 31, 2022. Therefore, our 2017 Convertible Notes were convertible at the holders’ option only through June 30, 2022. We received conversion notices on our 2017 Convertible Notes for an immaterial amount, none of which were settled, during the three months ended June 30, 2022. Through December 31, 2021, we separately accounted for the liability and equity components of convertible notes based on their relative values. Debt issuance costs related to the issuance of convertible notes were also previously allocated to the liability and equity components based on their relative values. With the adoption of the amended accounting guidance for convertible notes on January 1, 2022 (see Note 2 for further discussion), amounts, including debt issuance costs, that were previously classified within equity were reclassified to the liability component, net of any remaining unamortized amounts. Debt issuance costs are amortized to interest expense using the effective interest method over the term of each convertible notes. The 2017 Convertible Notes consisted of the following as of June 30, 2022: 2017 Convertible Notes Remaining life in months 23 Gross proceeds $ 289,000 Less: debt issuance cost, net of amortization ( 2,034 ) Net carrying amount $ 286,966 The following table presents the amount of interest expense recognized related to the convertible notes: For the Three Months Ended For the Six Months Ended June 30, 2022 June 30, 2021 June 30, 2022 June 30, 2021 Contractual interest coupon $ 2,196 $ 2,618 $ 4,814 $ 5,236 Amortization of debt discount - 4,745 - 9,416 Amortization of debt issuance costs 427 406 936 808 Total interest expense recognized $ 2,623 $ 7,769 $ 5,750 $ 15,460 Revolving Credit Facility In December 2021, we amended and extended our previous three-year $ 200.0 million secured revolving credit facility into a new four-year $ 250.0 million secured revolving credit facility (the “Revolver”) for general corporate purposes. As of June 30, 2022 , there were no amounts outstanding and we had $ 250.0 million of unused availability, based on the collateral borrowing base. Other Debt In April 2022, we refinanced a term loan secured by a 747-8F aircraft and received proceeds of $ 90.0 million from a financing with an 84-month term for this aircraft at a blended fixed rate of 3.86 %, with principal and interest payable quarterly. We used $ 45.7 million of the proceeds to repay a term loan in full and recognized a $ 0.7 million loss on early extinguishment of debt. In connection with entry into this financing, we paid usual and customary commitment and other fees. While the financing involved a sale and leaseback of the aircraft, it did not qualify as a sale for accounting purposes.

Fair Value Disclosures [Abstract]
Financial Instruments	9. Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Inputs used to measure fair value are classified in the following hierarchy: Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 Other inputs that are observable directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, or inactive quoted prices for identical assets or liabilities in inactive markets; Level 3 Unobservable inputs reflecting assumptions about the inputs used in pricing the asset or liability. We endeavor to utilize the best available information to measure fair value. The carrying value of Cash and cash equivalents, and Restricted cash is based on cost, which approximates fair value. Term loans and notes consist of term loans, notes guaranteed by the Export-Import Bank of the United States, a promissory note issued to the U.S. Treasury and other financings. The fair values of these debt instruments and the Revolver are based on a discounted cash flow analysis using current borrowing rates for instruments with similar terms. The fair value of our convertible notes is based on unadjusted quoted market prices for these securities. The following table summarizes the carrying value, estimated fair value and classification of our financial instruments as of: June 30, 2022 Carrying Value Fair Value Level 1 Level 2 Level 3 Assets Cash and cash equivalents $ 606,567 $ 606,567 $ 606,567 $ - $ - Restricted cash 10,361 10,361 10,361 - - $ 616,928 $ 616,928 $ 616,928 $ - $ - Liabilities Term loans and notes $ 1,678,463 $ 1,597,294 $ - $ - $ 1,597,294 Convertible notes (1) 286,966 333,795 333,795 - - $ 1,965,429 $ 1,931,089 $ 333,795 $ - $ 1,597,294 December 31, 2021 Carrying Value Fair Value Level 1 Level 2 Level 3 Assets Cash and cash equivalents $ 910,965 $ 910,965 $ 910,965 $ - $ - Restricted cash 10,052 10,052 10,052 - - $ 921,017 $ 921,017 $ 921,017 $ - $ - Liabilities Term loans and notes $ 1,638,311 $ 1,690,675 $ - $ - $ 1,690,675 Convertible notes (2) 479,573 758,424 758,424 - - $ 2,117,884 $ 2,449,099 $ 758,424 $ - $ 1,690,675 (1) Carrying value is net of debt issuance costs (see Note 7).

Segment Reporting [Abstract]
Segment Reporting	10. Segment Reporting We have the following two operating and reportable segments: Airline Operations and Dry Leasing, both of which are directly or indirectly engaged in the business of air transportation services but have different commercial and economic characteristics. Each operating segment is separately reviewed by our chief operating decision maker to assess operating results and make resource allocation decisions. We do not aggregate our operating segments and, therefore, our operating segments are our reportable segments. We use an economic performance metric called Direct Contribution, which shows the profitability of each segment. Direct Contribution includes Income before income taxes and excludes the following: Special charges, Transaction-related expenses, nonrecurring items, Loss (gain) on disposal of flight equipment, Losses on early extinguishment of debt, Unrealized loss on financial instruments and Unallocated income and expenses, net. Direct operating and ownership costs include crew costs, maintenance, fuel, ground operations, sales costs, aircraft rent, interest expense on the portion of debt used for financing aircraft, interest income on debt securities and aircraft depreciation. Unallocated income and expenses, net include corporate overhead, nonaircraft depreciation, noncash expenses and income, interest expense on the portion of debt used for general corporate purposes, interest income on nondebt securities, capitalized interest, foreign exchange gains and losses, other revenue, other non-operating costs and CARES Act grant income.

Labor And Legal Proceedings [Abstract]
Labor and Legal Proceedings	11. Labor and Legal Proceedings Collective Bargaining Agreements Pilots of Atlas and flight dispatchers of Atlas and Polar are represented by the International Brotherhood of Teamsters (the “IBT”). We had a five-year collective bargaining agreement (“CBA”) with our Atlas pilots, which became amendable in September 2016, and a four-year CBA with the Southern Air pilots, which became amendable in November 2016. On November 17, 2021, the Southern Air pilots all transferred to Atlas with the issuance of a single operating certificate for Atlas by the U.S. Federal Aviation Administration. In March 2022, we signed a new five-year CBA with our pilots, effective as of September 2021. This long-term CBA was reached through a binding arbitration process, with the arbitrator’s decision being issued on September 10, 2021. The new pay rates became effective as of September 1, 2021, and we are continuing to work closely together with the union’s new leadership on the final implementation of certain remaining provisions of the CBA. Under this industry competitive agreement, all of our pilots are receiving significantly higher pay, quality of life improvements and enhanced benefits. We also have a five-year CBA with our Atlas and Polar dispatchers, which was extended in April 2017 for an additional four years , making the CBA amendable in November 2021. On September 15, 2021, the IBT, representing the flight dispatchers of Atlas and Polar, provided the Company with the requisite notice of its intent to commence negotiations for a new CBA pursuant to Section 6 of the Railway Labor Act. The Company and the IBT commenced bargaining with good faith discussions and are making progress towards an amended CBA. We are subject to risks of work interruption or stoppage as permitted by the Railway Labor Act and may incur additional administrative expenses associated with union representation of our employees. Matters Related to Alleged Pricing Practices In the Netherlands, Stichting Cartel Compensation, successor in interest to claims of various shippers, has filed suit in the district court in Amsterdam against British Airways, KLM, Martinair, Air France, Lufthansa and Singapore Airlines seeking recovery for damages purportedly arising from allegedly unlawful pricing practices of such defendants. In response, British Airways, KLM, Martinair, Air France and Lufthansa filed third-party indemnification lawsuits against Polar Air Cargo, LLC (“Old Polar”), a consolidated subsidiary of the Company, and Polar, seeking indemnification in the event the defendants are found to be liable in the main proceedings. Another defendant, Thai Airways, filed a similar indemnification claim. Activities in the case have focused on various procedural issues and rulings, some of which are awaiting court decisions on appeal. The ultimate outcome of the lawsuit is likely to be affected by a decision readopted by the European Commission in March 2017, finding EU competition law violations by British Airways, KLM, Martinair, Air France and Lufthansa, among others, but not Old Polar or Polar. If the Company, Old Polar or Polar were to incur an unfavorable outcome, such outcome may have a material adverse impact on our business, financial condition, results of operations or cash flows. We are unable to reasonably estimate a range of possible loss for this matter at this time. Brazilian Customs Claim Old Polar was cited for an alleged customs violation in Sao Paulo, Brazil, relating to shipments of goods dating back to asserting that goods listed on the flight manifest of an Old Polar scheduled service flight were not properly presented to customs upon arrival and therefore were improperly brought into Brazil. The claim, which also seeks unpaid customs duties, taxes and penalties from the date of the alleged infraction, is approximately $ 1.9 million in aggregate based on June 30, 2022 exchange rates. Old Polar has presented evidence that certain of the alleged missing goods were in fact never onboard the aircraft (due to a change in plans by the relevant shipper) and thus no customs duties should be due. Further, we believe that the amounts claimed are substantially overstated due to a calculation error when considering the type and amount of goods allegedly missing, among other things. As required to defend this claim, we have made deposits pending resolution of the matter. The balance was $ 3.6 million as of June 30, 2022 and $ 3.2 million as of December 31, 2021, and is included in Deferred costs and other assets. We are currently defending this and other Brazilian customs claims and the ultimate disposition of these claims, either individually or in the aggregate, is not expected to materially affect our financial condition, results of operations or cash flows. Other In addition to the matters described in this note, we have certain other litigation contingencies incident to the ordinary course of business. Unless disclosed otherwise, management does not expect that the ultimate disposition of such other contingencies or matters will materially affect our financial condition, results of operations or cash flows.

Treasury Stock [Abstract]
Stock Repurchases	12. Stock Repurchases We record the repurchase of our shares of common stock at cost based on the settlement date of the transaction. These shares are classified as treasury stock, which is a reduction to stockholders’ equity. Treasury shares are included in authorized and issued shares but excluded from outstanding shares. In February 2022, our board of directors approved the establishment of a new stock repurchase program authorizing the repurchase of up to a total of $ 200.0 million of our common stock. Purchases may be made at management's discretion in the form of accelerated share repurchase programs, open market repurchase programs, privately negotiated transactions or a combination of these methods. In February 2022, we paid $ 100.0 million and received an initial delivery of 1,061,257 shares pursuant to an accelerated share repurchase program agreement with a financial institution for the repurchase of our common stock (the “ASR”). We accounted for this ASR as a repurchase of common stock and as a forward contract indexed to our own common stock. We determined that the forward contract met all of the applicable criteria for equity classification and, therefore, this ASR was not accounted for as a derivative instrument. In April 2022, the ASR was settled and we received an additional 172,887 shares of common stock. In the aggregate, we repurchased 1,234,144 shares for $ 100.0 million at an average cost of $ 81.03 per share under this ASR. The total number of shares of common stock repurchased by us was based on the volume-weighted average price of the common stock during the term of the ASR Agreement, less a pre-determined discount.

Earnings Per Share [Abstract]
Earnings Per Share	13. Earnings Per Share Basic earnings per share (“EPS”) represents income divided by the weighted average number of common shares outstanding during the measurement period. Diluted EPS represents income divided by the weighted average number of common shares outstanding during the measurement period while also giving effect to all potentially dilutive common shares that were outstanding during the period. The calculations of basic and diluted EPS were as follows: For the Three Months Ended For the Six Months Ended Numerator: June 30, 2022 June 30, 2021 June 30, 2022 June 30, 2021 Net Income $ 88,258 $ 107,110 $ 169,769 $ 197,043 Plus: Interest expense on convertible notes, net of tax 1,040 - 2,086 - Unrealized loss on financial instruments, net of tax - - - 112 Diluted net income $ 89,298 $ 107,110 $ 171,855 $ 197,155 Denominator: Basic EPS weighted average shares outstanding 28,243 29,011 28,547 28,752 Effect of dilutive: Convertible notes 4,731 608 4,881 304 Warrants 590 499 600 625 Restricted stock 115 201 156 219 Diluted EPS weighted average shares outstanding 33,679 30,319 34,184 29,900 Earnings per share: Basic $ 3.12 $ 3.69 $ 5.95 $ 6.85 Diluted $ 2.65 $ 3.53 $ 5.03 $ 6.59 Antidilutive shares related to warrants issued in connection with our convertible notes or to customers that were out of the money and excluded from the calculation of diluted EPS were zero for the three and six months ended June 30, 2022 , and 3.0 million for the three and six months ended June 30, 2021 . Diluted shares reflect the potential dilution that could occur from restricted shares using the treasury stock method. The calculation of EPS does not include restricted share units and customer warrants in which performance or market conditions were not satisfied of 9.3 million for the three and six months ended June 30, 2022 and 9.9 million for the three and six months ended June 30, 2021 .

Subsequent Events [Abstract]
Subsequent Event	15. Subsequent Event On August 4, 2022, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Rand Parent, LLC, a Delaware limited liability company (“Parent”) affiliated with certain funds managed by affiliates of Apollo Global Management, Inc., J.F. Lehman & Company, Inc. and Hill City Capital L.P. (collectively, the “Buyers”) and Rand Merger Sub, Inc, a Delaware corporation and wholly owned subsidiary of Parent (“MergerCo”), pursuant to which, subject to the terms and conditions thereof, MergerCo will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Consummation of the Merger is subject to the approval of the Company’s stockholders and other customary closing conditions. Upon completion of the Merger, AAWW will become a privately held company and shares of AAWW common stock will no longer be listed or publicly traded on The NASDAQ Global Select Market. Subject to the terms and conditions set forth in the Merger Agreement, which has been unanimously approved by the board of directors, at the effective time of the Merger (the “Effective Time”), each share of the Company’s common stock issued and outstanding (subject to certain exceptions set forth in the Merger Agreement) shall be converted into the right to receive $ 102.50 in cash, without interest (the “Merger Consideration”). At the Effective Time, each outstanding share of Warrant B issued to Amazon shall automatically vest and be exercised in accordance with its terms for the Merger Consideration and each outstanding warrant issued to the U.S. Treasury shall become exercisable for the Merger Consideration. No other warrants issued to Amazon will vest or become exercisable in connection with the Merger. In addition, at the Effective Time, each restricted share unit (including those subject to performance-based vesting conditions) will vest and be canceled and the holder will be entitled to receive an amount in cash equal to the number of shares of common stock underlying such award (assuming all performance goals are achieved at the maximum level of performance) multiplied by the Merger Consideration. The consummation of the Merger is subject to certain closing conditions, including, among other things: (i) the approval of the Company’s stockholders; (ii) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended as well as certain non-U.S. antitrust approvals; (iii) the receipt of certain required consents or approvals from (a) the U.S. Department of Transportation, (b) the Federal Communications Commission and (c) certain other regulatory agencies; (iv) the absence of legal restraints prohibiting the Merger; and (v) other customary conditions specified in the Merger Agreement. The Merger Agreement contains certain termination rights for the Company and Parent, including, among others, the right of (1) either party to terminate the Merger Agreement if the Merger is not consummated by March 4, 2023 (subject to certain exceptions set forth in the Merger Agreement), (2) the Company to terminate the Merger Agreement in order to enter into a definitive acquisition agreement providing for a Superior Proposal (as defined in the Merger Agreement) and (3) Parent to terminate the Merger Agreement if the Board changes its recommendation with respect to the Merger Agreement. Upon termination of the Merger Agreement under specified circumstances, the Company will be required to pay Parent a termination fee. Generally, if the termination fee becomes payable as a result of the Company terminating the Merger Agreement in order to enter into a definitive acquisition agreement, or by Parent as a result of the Board changing its recommendation with respect to the Merger or under certain other circumstances, the amount of the termination fee will be $ 97.5 million. If the Company terminates the Merger Agreement as a result of Parent’s breach of the Merger Agreement or because Parent fails to consummate the Merger when required by the Merger Agreement, the Company will be entitled to a termination fee of $ 227.4 million.

Accounting Policies [Abstract]
Heavy Maintenance	Heavy Maintenance Except as described in the paragraph below, we account for heavy maintenance costs for airframes and engines using the direct expense method. Under this method, heavy maintenance costs are charged to expense upon induction, based on our best estimate of the costs after considering multiple factors, including historical costs, experience and information provided by third-party maintenance providers. These estimates may be subsequently adjusted for changes and the final determination of actual costs incurred. As of June 30, 2022 and December 31, 2021 , Accrued heavy maintenance was $ 72.3 million and $ 79.6 million, respectively. We account for heavy maintenance costs for airframes and engines used in our Dry Leasing segment and engines used on our 747-8F and 777-200 aircraft using the deferral method. Under this method, we defer the expense recognition of scheduled heavy maintenance events, which are amortized over the shorter of the estimated period until the next scheduled heavy maintenance event is required or remaining lease term. Amortization of deferred maintenance expense included in Depreciation and amortization was $ 12.2 million and $ 23.3 million for the three and six months ended June 30, 2022 , respectively. Amortization of deferred maintenance expense included in Depreciation and amortization was $ 12.3 million and $ 24.3 million for the three and six months ended June 30, 2021 , respectively. Deferred maintenance included within Deferred costs and other assets is as follows: Balance as of December 31, 2021 $ 180,675 Deferred maintenance costs 14,236 Special charge (1) ( 1,628 ) Amortization of deferred maintenance ( 23,325 ) Balance as of June 30, 2022 $ 169,958 (1) See Note 6 for further discussion.
Property and Equipment	Property and Equipment Committed capital expenditures are expected to be $ 501.8 million for the remainder of 2022 and $ 359.7 million in 2023. These expenditures include delivery payments for our January 2021 agreement to purchase four 747-8F aircraft from The Boeing Company (“Boeing”), the first of these aircraft was delivered during the second quarter of 2022 and the remaining three are expected to be delivered throughout 2022. These amounts also include pre-delivery and delivery payments for our December 2021 agreement to purchase four new 777-200LRF aircraft from Boeing, the first of these aircraft is expected to be delivered late in the fourth quarter of 2022 and the remaining three throughout 2023. In addition, the amounts include other agreements to acquire spare engines.
Payroll Support Program under the CARES Act	Payroll Support Program under the CARES Act In May 2020, two subsidiaries of the Company, Atlas and Southern Air, Inc. (“Southern Air”, and together with Atlas, the “PSP Recipients”) entered into an agreement with the U.S. Treasury (the "PSP Agreement") with respect to payroll support funding available to cargo carriers under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). AAWW also entered into a Warrant Agreement (the “Warrant Agreement”) with the U.S. Treasury, and AAWW issued a senior unsecured promissory note to the U.S. Treasury (the “Promissory Note”), with the PSP Recipients as guarantor. In connection with the payroll support funding received in 2020 under the PSP Agreement, we issued warrants to the U.S. Treasury to acquire up to 625,452 shares of our common stock. The warrants will expire in 2025 on the fifth anniversary of the issue date of each warrant. As of June 30, 2022 , no portion of the warrants have been exercised. We initially recognized deferred grant income within Accrued liabilities for the difference between the payroll support funding received in 2020 under the PSP Agreement and the amounts recorded for the Promissory Note and the Warrant Agreement. All grant income has been subsequently recognized within Other (income) expense, net in the consolidated statement of operations on a pro-rata basis over the periods that the qualifying employee wages, salaries and benefits were paid. During the six months ended June 30, 2021 , we recognized the remaining $ 40.9 million of deferred grant income within Other (income) expense, net in the consolidated statement of operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncement Adopted in 2022 In August 2020, the Financial Accounting Standards Board amended its accounting guidance for certain financial instruments with characteristics of liabilities and equity, including convertible debt instruments. For convertible debt with a cash conversion feature, the amended guidance removes the accounting model to separately account for the liability and equity components, which resulted in the amortization of a debt discount to interest expense. Under this amended guidance, such convertible debt is accounted for as a single debt instrument with no amortization of a debt discount, unless certain other conditions are met. The amended guidance also requires the use of the if-converted method when calculating the dilutive impact of convertible debt on earnings per share. Effective January 1, 2022, we adopted the amended guidance using the modified retrospective approach, under which the guidance was applied only to the most current period presented. On January 1, 2022, we recorded an increase of $ 31.0 million to the carrying value of our convertible notes, a reduction of $ 6.9 million to deferred tax liabilities, a reduction of $ 92.6 million to Additional paid-in capital and an increase of $ 68.5 million to Retained earnings for the cumulative effect of adoption.
