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 its principal operating subsidiary, Atlas Air, Inc. (“Atlas”), and of Polar Air Cargo LLC (“Old Polar”). AAWW is also the parent company of several subsidiaries related to our dry leasing services (collectively referred to as “Titan”).
	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”), as well as those through which we provide crew, maintenance and insurance, with the customer providing the aircraft (“CMI”); (ii) cargo and passenger charter services (“Charter”); and (iii) 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”). All significant 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, 2014, which includes additional disclosures and a summary of our significant accounting policies. The December 31, 2014 balance sheet data was derived from that Annual Report. In our opinion, the Financial Statements contain all adjustments, consisting of normal recurring items, necessary to fairly state the financial position of AAWW and its consolidated subsidiaries as of March 31, 2015, the results of operations for the three months ended March 31, 2015 and 2014, comprehensive income for the three months ended March 31, 2015 and 2014, cash flows for the three months ended March 31, 2015 and 2014, and shareholders’ equity as of and for the three months ended March 31, 2015 and 2014.
	Our quarterly results are subject to seasonal and other fluctuations, 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.
	Certain reclassifications have been made to prior periods’ consolidated financial statement amounts and related note disclosures to conform to the current year’s presentation, including the presentation of segments.

Recently Adopted Accounting Pronouncements [Abstract]
Recently Adopted Accounting Pronouncements	2. Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) amended its accounting guidance for revenue recognition. The fundamental principles of the new guidance are that companies should recognize revenue in a manner that reflects the timing of the transfer of services to customers and consideration that a company expects to receive for the services provided. It also requires additional disclosures necessary for the financial statement users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. On April 1, 2015, the FASB proposed deferring the effective date by one year to the beginning of 2018. The FASB also proposed permitting early adoption of the standard, but not before the beginning of 2017. We are currently assessing the impact the amended guidance will have on our financial statements.
	In April 2015, the FASB amended its guidance for presenting debt issuance costs. The new guidance requires debt issuance costs to be presented in the balance sheet as a reduction of the carrying amount of the related debt liability instead of as an asset. We early adopted this guidance retrospectively effective March 31, 2015 and its adoption did not have a material impact on our financial condition, results of operations or cash flows. The amount of debt issuance costs classified as a reduction of debt was $52.8 million at March 31, 2015 and $55.1 million at December 31, 2014.

	DHL Investment and Polar
	AAWW has a 51% equity interest and 75% voting interest in Polar Air Cargo Worldwide, Inc. (“Polar”). DHL Network Operations (USA), Inc. (“DHL”), a subsidiary of Deutsche Post AG (“DP”), 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. We record our share of Polar’s results under the equity method of accounting. Under a 20-year blocked space agreement (the “BSA”), Polar provides air cargo capacity to DHL. Atlas has several agreements with Polar to provide ACMI, CMI, administrative, sales and ground support services to one another. We do not have any financial exposure to fund debt obligations or operating losses of Polar, except for any liquidated damages that we could incur under these agreements. The following table summarizes our transactions with Polar:

	GATS
	We hold a 50% interest in Global Aviation Technical Solutions Co, Ltd. (“GATS”), a joint venture with an unrelated third party. The purpose of the joint venture is to purchase rotable parts and provide repair services for those parts, primarily for our 747-8F aircraft. The joint venture is a variable interest entity that we do not consolidate because we are not the primary beneficiary as we do not exercise financial control. As of March 31, 2015 and December 31, 2014, our investment in GATS was $16.8 million and $16.4 million, respectively, and our maximum exposure to losses from the entity is limited to our investment, which is comprised primarily of rotable inventory parts. GATS does not have any third-party debt obligations. We had Accounts payable to GATS of $1.4 million as of March 31, 2015 and $1.5 million as of December 31, 2014.

	During the three months ended March 31, 2015 and March 31, 2014, we recorded adjustments of $0.4 million and $0.6 million, respectively, to the Special charge related to the early termination of operating leases for two 747-400BCF aircraft that we parked in December 2013. Substantially all remaining cash payments related to the lease termination costs are expected to be paid in 2015.
	During the three months ended March 31, 2014, we recognized $2.3 million of employee termination benefits related to British Airways Plc’s (“British Airways”) return of three 747-8F aircraft in 2014. In addition, we recognized a reserve of $5.1 million during the three months ended March 31, 2014 related to a loan from Global Supply Systems Limited (“GSS”), a consolidated subsidiary, to its 51% U.K. shareholder.
	A summary of the Special charge liabilities is as follows:

Income Taxes [Abstract]
Income Taxes	6. Income Taxes
	Our effective income tax rate was 19.4% for the three months ended March 31, 2015 and 38.7% for the three months ended March 31, 2014. The effective rate for the three months ended March 31, 2015 differed from the U.S. federal statutory rate primarily due to an income tax benefit of $4.0 million, net of reserves, related to extraterritorial income (“ETI”) from leasing certain of our aircraft. The effective rate for the three months ended March 31, 2014 differed from the U.S. federal statutory rate primarily due to losses associated with GSS for which we have recognized a valuation allowance due to the uncertainty that the benefit of the losses will be realized. The effective rates also differed from the U.S. federal statutory rate due to the income tax impact of foreign operations taxed at different rates, our assertion to indefinitely reinvest the net earnings of certain foreign subsidiaries outside the U.S., U.S. state income taxes, the nondeductibility of certain expenses for tax purposes, adjustments to our liability for uncertain tax positions, and the relationship of these items to our projected operating results for the year. For interim accounting purposes, we recognize income taxes using an estimated annual effective tax rate.
	As a result of current and expected future growth in our Dry Leasing business, we determined to indefinitely reinvest the net earnings of certain foreign subsidiaries engaged in this business outside of the U.S. Our effective income tax rates for the three months ended March 31, 2015 and 2014 were favorably impacted by this determination. As of March 31, 2015, our undistributed net earnings of foreign subsidiaries for which deferred taxes have not been provided were $53.0 million, and the unrecognized deferred tax liability associated with these earnings was $18.5 million.

Financial Instruments [Abstract]
Financial Instruments	7. 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, Short-term investments and Restricted cash is based on cost, which approximates fair value.
	Long-term investments consist of debt securities for which we have both the ability and the intent to hold until maturity. These investments are classified as held-to-maturity and reported at amortized cost. The fair value of our Long-term investments is based on a discounted cash flow analysis using the contractual cash flows of the investments and a discount rate derived from unadjusted quoted interest rates for debt securities of comparable risk. Such debt securities represent investments in Pass-Through Trust Certificates related to enhanced equipment trust certificates (“EETCs”) issued by Atlas in 1998, 1999 and 2000.
	The fair value of our term loans, notes guaranteed by the Export-Import Bank of the United States (“Ex-Im Bank”) and EETCs are based on a discounted cash flow analysis using current borrowing rates for instruments with similar terms.
	The following table summarizes the carrying amount, estimated fair value and classification of our financial instruments as of:

Segment Reporting	8. Segment Reporting
	We currently have the following three reportable segments: ACMI, Charter and Dry Leasing. We use an economic performance metric (“Direct Contribution”) that shows the profitability of each segment after allocation of operating and ownership costs. The following table sets forth Operating Revenue and Direct Contribution for our reportable segments reconciled to Operating Income and Income before Income Taxes:
		For the Three Months Ended

	*During the first quarter of 2015, we changed the methodology for allocating certain unallocated expenses to our segments. The prior period information has been adjusted to consistently reflect this change.
	We are exposed to a concentration of revenue from the U.S. Military Air Mobility Command (the “AMC”) and Polar (see Note 3 for further discussion regarding Polar). No other customer accounted for more than 10.0% of our Total Operating Revenue. Revenue from the AMC was $90.1 million for the three months ended March 31, 2015 and $62.9 million for the three months ended March 31, 2014. Accounts receivable from the AMC were $20.3 million and $15.3 million as of March 31, 2015 and December 31, 2014, respectively. We have not experienced any credit issues with either of these customers.

Labor And Legal Proceedings [Abstract]
Legal Proceedings	9. Legal Proceedings
	Matters Related to Alleged Pricing Practices
	The Company and Old Polar have been named defendants, along with a number of other cargo carriers, in several class actions in the United States arising from allegations about the pricing practices of Old Polar and a number of air cargo carriers that have now been centralized for pretrial purposes in the United States District Court for the Eastern District of New York. The consolidated complaint alleges, among other things, that the defendants, including the Company and Old Polar, manipulated the market price for air cargo services sold domestically and abroad through the use of surcharges, in violation of United States, state, and European Union antitrust laws. The suit seeks treble damages and injunctive relief.
	In 2007, the Company and Old Polar commenced an adversary proceeding in bankruptcy court against each of the plaintiffs in this class action litigation seeking to enjoin the plaintiffs from prosecuting claims against the Company and Old Polar that arose prior to July 28, 2004, the date on which the Company and Old Polar emerged from bankruptcy. In 2007, the plaintiffs consented to the injunctive relief requested and the bankruptcy court entered an order enjoining plaintiffs from prosecuting Company claims arising prior to July 28, 2004.
	The court in the antitrust class actions has heard and decided a number of procedural motions. Among those was the plaintiffs’ motion to join Polar Air Cargo Worldwide, Inc. as an additional defendant, which the court granted for discovery purposes on April 13, 2011. There was substantial pretrial written discovery and document production, and a number of depositions were taken. A court hearing on whether or not to certify the case as a class action was held in October 2013, and oral arguments and an evidentiary hearing were held in November 2013. On October 15, 2014, the magistrate judge issued a decision recommending that the court enter an order certifying the class for adjudicating the claims. We filed our opposition to that recommendation with the judge on December 1, 2014 and also intend to vigorously pursue a number of defenses. We are unable to reasonably predict the court’s ruling on our opposition to class certification and our defenses, or the ultimate outcome of the litigation.
	In the United Kingdom, several groups of named claimants have brought suit against British Airways in connection with the same alleged antitrust practices at issue in the proceedings described above and are seeking damages allegedly arising from that conduct. British Airways has filed claims in the lawsuit against Old Polar, the Company and a number of air cargo carriers for contribution should British Airways be found liable to claimants. Old Polar’s formal statement of defense was filed on February 28, 2015. Old Polar intends to mount a vigorous defense.
	If the Company or Old Polar were to incur an unfavorable outcome in connection with one or more of the matters described above, such outcome is not expected to materially affect our business, financial condition, results of operations or cash flows.
	Brazilian Customs Claim
	Old Polar was cited for two alleged customs violations in Sao Paulo, Brazil, relating to shipments of goods dating back to 1999 and 2000. Each claim asserts that goods listed on the flight manifest of two separate Old Polar scheduled service flights were not on board the aircraft upon arrival and therefore were improperly brought into Brazil. The two claims, which also seek unpaid customs duties, taxes and penalties from the date of the alleged infraction, are approximately $6.1 million in aggregate based on March 31, 2015 exchange rates.
	In both cases, 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. Furthermore, we may seek appropriate indemnity from the shipper in each claim as may be feasible. In the pending claim for one of the cases, we have received an administrative decision dismissing the claim in its entirety, which remains subject to a mandatory appeal by the Brazil customs authorities. As required to defend such claims, we have made deposits pending resolution of these matters. The balances were $4.4 million as of March 31, 2015 and $5.3 million as of December 31, 2014, and are included in Deposits and other assets.
	We are currently defending these 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
	We have certain other contingencies incident to the ordinary course of business. Management believes that the ultimate disposition of such other contingencies is not expected to materially affect our financial condition, results of operations or cash flows.

Earnings Per Share [Abstract]
Earnings Per Share	10. Earnings Per Share
	Basic earnings per share (“EPS”) represent net income attributable to common shareholders divided by the weighted average number of common shares outstanding during the measurement period. Diluted EPS represent net income attributable to common shareholders 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. Anti-dilutive options that were out of the money for the three months ended March 31, 2015 and 2014 were de minimis and excluded.
	The calculations of basic and diluted EPS were as follows:

	EPS:

	Diluted	$	1.17	$	0.32
	Diluted shares reflect the potential dilution that could occur from stock options and restricted share units using the treasury stock method. The calculation does not include restricted share units in which performance or market conditions were not satisfied of 0.3 million for the three months ended March 31, 2015 and 0.5 million for the three months ended March 31, 2014.

	As of March 31, 2015, there was $15.4 million of unamortized realized loss before taxes remaining in Accumulated other comprehensive income (loss) related to terminated forward-starting interest rate swaps, which had been designated as cash flow hedges to effectively fix the interest rates on two 747-8F financings in 2011 and three 777-200LRF financings in 2014. The net loss is amortized and reclassified into Interest expense over the remaining life of the related debt. Net realized losses reclassified into earnings were $0.7 million for the three months ended March 31, 2015 and 2014. Net realized losses expected to be reclassified into earnings within the next 12 months are $2.5 million as of March 31, 2015.
