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”). In addition, we are the primary beneficiary of Global Supply Systems Limited (“GSS”), a consolidated subsidiary. AAWW 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.
	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 services, with the customer providing the aircraft (“CMI”); (ii) military charter services provided to the U.S. Military Air Mobility Command (the “AMC”) (“AMC Charter”); (iii) seasonal, commercial and ad hoc charter services (“Commercial Charter”); and (iv) dry leasing of 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, 2013, which includes additional disclosures and a summary of our significant accounting policies. 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, 2014, the results of operations for the three months ended March 31, 2014 and 2013, comprehensive income for the three months ended March 31, 2014 and 2013, cash flows for the three months ended March 31, 2014 and 2013, and shareholders' equity as of and for the three months ended March 31, 2014 and 2013.
	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' unaudited consolidated financial statement amounts and related note disclosures to conform to the current period's presentation.

	DHL Investment and 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 and we do not consolidate Polar 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 (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 and we have not consolidated GATS because we are not the primary beneficiary as we do not exercise financial control. As of March 31, 2014 and December 31, 2013, our investment in GATS was $13.1 million and $13.2 million, respectively, and our maximum exposure to losses from the entity is limited to our investment, which is comprised primarily of rotable parts. GATS does not have any third-party debt obligations.

Special Charge	'
	3. Special Charge
	We hold a 49% interest in GSS, a private company. GSS is a variable interest entity and we are the primary beneficiary of GSS for financial reporting purposes. Atlas dry leases three 747-8F owned aircraft to GSS. The leases provide for payment of rent and a provision for maintenance costs associated with the aircraft. GSS provides ACMI services to British Airways Plc (“British Airways”) using these three aircraft. In January 2014, British Airways notified us that they would be terminating the ACMI agreement and returning three 747-8F aircraft in April 2014. As a result, we recognized $2.3 million of employee termination benefits during the three months ended March 31, 2014, after management determined that such costs were probable and estimable. The employee termination benefits are expected to be paid in the second quarter of 2014. We may recognize additional termination benefit costs in future periods. In addition, we recognized a reserve of $5.1 million related to a loan from GSS to its 51% U.K. shareholder.
	During the three months ended March 31, 2014, we recorded an adjustment of $0.6 million to the Special charge related to the early termination of operating leases for two 747-400BCF aircraft that we permanently parked in December 2013. The adjustment was related to additional costs to satisfy return conditions. Substantially all cash payments related to the lease termination costs are expected to be paid by 2015.
	A summary of the Special charge liabilities is as follows:
		Lease Termination Costs		GSS Employee Termination Benefits		Total
	Liability as of December 31, 2013	$	12,773	$	-	$	12,773

	Ex-Im Bank Guaranteed Notes
	In January 2014, we refinanced a bridge loan with a note guaranteed by the Export-Import Bank of the United States (“Ex-Im Bank”) in the amount of $140.6 million secured by a mortgage on a 747-8F aircraft (aircraft tail number N854GT) for a period of 134 months (the “2014 Ex-Im Guaranteed Note”). In connection with entry into this guaranteed note, we paid usual and customary fees. This guaranteed note accrues interest at a fixed rate of 2.67% with principal and interest payable quarterly and contains customary covenants and event of default provisions.
	Term Loans
	In January 2014, we purchased three 777-200LRF aircraft that are leased to a customer on a long-term basis. We accounted for the purchase as an asset acquisition and recognized a lease intangible of $42.7 million related to the long-term Dry Leases, which will be amortized on a straight-line basis over the life of the leases. As part of the transaction, we entered into six separate term loans in the aggregate amount of $432.0 million each secured by a mortgage on the aircraft and the attached leases (the “2014 Term Loans”). In connection with entry into these term loans, we paid usual and customary fees. The term loans accrue interest with principal and interest payable quarterly and contain customary covenants and event of default provisions.
	The following table summarizes the terms and amounts for each term loan (in millions):
						Collateral		Interest

Income Taxes	'
	6. Income Taxes
	Our effective income tax rates were an expense of 38.7% for the three months ended March 31, 2014 and a benefit of 97.4% for the three months ended March 31, 2013. 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 rate for the three months ended March 31, 2013 differed from the U.S. federal statutory rate primarily due to an income tax benefit of $14.2 million related to extraterritorial income (“ETI”) from certain of our aircraft. The effective rates in both periods also differed from the U.S. federal statutory rate due to the income tax impact of foreign operations taxed at different rates, 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 that the net earnings of certain foreign subsidiaries engaged in this business will be indefinitely reinvested outside of the U.S. Our effective rate for the three months ended March 31, 2014 was favorably impacted by our assertion to indefinitely reinvest these net earnings. As of March 31, 2014, our undistributed net earnings of foreign subsidiaries for which deferred taxes have not been provided were $18.1 million, and the unrecognized deferred tax liability associated with these earnings was $6.3 million.

	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.
	We maintain Cash and cash equivalents, Short-term investments and Restricted cash, which include cash on hand, demand deposits, other cash investments that are highly liquid in nature and have original maturities of three months or less at acquisition, money market funds, certificates of deposit and the current portion of debt securities. 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. Interest on debt securities and accretion of discounts using the effective interest method are included in Interest income.
	The fair value of our EETCs is measured based on Level 3 inputs. Fair value is based on a discounted cash flow analysis using current borrowing rates for instruments with similar terms.
	The fair values of our term loans and the Ex-Im Bank guaranteed notes are based on a discounted cash flow analysis using current borrowing rates for instruments with similar terms.
	The fair value of our interest rate derivatives was based on Level 2 inputs utilized in expected cash flow models. The market inputs used included the implied forward LIBOR yield curve for the same period as the future interest rate swap settlements. These derivatives were designated as hedging instruments.

	9. Legal Proceedings
	Department of Justice Investigation and Related Litigation
	In 2010, Old Polar entered into an agreement with the United States Department of Justice (the "DOJ") to resolve issues relating to the previously disclosed DOJ investigation concerning alleged manipulation by cargo carriers of fuel surcharges and other rate components for air cargo services (the “DOJ Investigation”).
	As a result of the DOJ Investigation, 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 a number of air cargo carriers that have now been consolidated 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 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 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 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 were held in November 2013. We are unable to reasonably predict the court's ruling or the ultimate outcome of the litigation.
	The Company, Old Polar and a number of other cargo carriers have also been named as defendants in civil class action suits in the provinces of British Columbia, Ontario and Quebec, Canada that are substantially similar to the class action suits in the United States. The plaintiffs in the British Columbia case have indicated they do not intend to pursue their lawsuit against the Company and Old Polar. We are unable to reasonably predict the outcome of the litigation in Ontario and Quebec.
	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, and/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 $8.7 million in aggregate based on March 31, 2014 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 $6.0 million as of March 31, 2014 and $5.7 million as of December 31, 2013, 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.
	Trademark Matters
	Since 2005, we have been involved in ongoing litigation in Europe against Atlas Transport, an unrelated and unaffiliated entity, over the use of the name “Atlas”. Following application by us to register the mark “ATLAS AIR” in the European Union (“EU”), opposition from Atlas Transport and follow-up filings by us, the Office for Harmonization in the Internal Market (“OHIM”), which handles trademark matters in the EU, declared Atlas Transport's own trademark “ATLAS” partially invalid because of the prior existence of our Benelux trademark registration.  In 2008, OHIM's First Board of Appeal upheld the lower panel's decision, and Atlas Transport appealed that decision to the EU General Court (formally the Court of First Instance), which upheld the court's decision on May 18, 2011. Atlas Transport appealed that ruling to the European Court of Justice (“ECJ”). On March 9, 2012, the ECJ denied the appeal, bringing to an end that aspect of the OHIM proceedings. The Company's request for OHIM to resume another aspect of the proceedings remains pending.
	In 2007, Atlas Transport also filed a lawsuit in the Netherlands challenging the validity of our Benelux trademark. In 2009, following completion of its proceedings, the court issued a judgment in favor of us. Atlas Transport appealed that decision to the Dutch Court of Appeal, but the judgment took effect immediately upon entry. An appellate hearing was held on March 20, 2014, and the court's decision is pending.
	In 2009, Atlas Transport instituted a trademark infringement lawsuit against us in the regional court in Hamburg, Germany. The amended complaint alleges that Atlas Air has been unlawfully using Atlas Transport's trademark in Germany without permission and should be required to render information on the scope of use and pay compensation. In a supplementary motion, Atlas Transport asserts a cease and desist claim against Atlas Air, to be considered if the court denies the claim for compensation. On May 31, 2011, the court dismissed the case and Atlas Transport filed an appeal, which remains pending.
	We believe that the ultimate disposition of these claims, either individually or in the aggregate, will not 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, 2014 and 2013 were de minimis and excluded.
	The calculations of basic and diluted EPS were as follows:
		For the Three Months Ended

	EPS:

	Diluted	$	0.32	$	0.76
	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 0.5 million for the three months ended March 31, 2014 and 0.6 million for the three months ended March 31, 2013.

	Interest Rate Derivatives
	In December 2013, we entered into six forward-starting interest rate swaps with a total notional value of $432.5 million to hedge the risk of changes in quarterly interest payments due to fluctuations in the forward 90-day LIBOR swap rate for debt issuances. The debt issuances were related to the financing of three Boeing 777-200LRF aircraft that we purchased in January 2014 (see Note 5).
	In January 2014, we terminated all six of the forward-starting interest rate swaps in connection with the debt issuances, which converted a previously unrealized gain of $1.1 million into a realized gain in Accumulated other comprehensive income (loss). There was no ineffectiveness associated with these hedges upon their termination.
	As of March 31, 2014, there was $18.0 million of net 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 the 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 and $0.8 million for the three months ended March 31, 2014 and 2013, respectively. Net realized losses expected to be reclassified into earnings within the next 12 months are $2.7 million as of March 31, 2014.
