Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies
	Organization and Basis of Presentation
	Aircastle Limited (“Aircastle,” the “Company,” “we,” “us” or “our”) is a Bermuda exempted company that was incorporated on October 29, 2004 under the provisions of Section 14 of the Companies Act of 1981 of Bermuda. Aircastle’s business is investing in aviation assets, including acquiring, leasing, managing and selling high utility commercial jet aircraft.
	Aircastle is a holding company that conducts its business through subsidiaries. Aircastle directly or indirectly owns all of the outstanding common shares of its subsidiaries. The consolidated financial statements presented are prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”). We operate in one segment.
	The accompanying consolidated financial statements are unaudited and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting and, in our opinion, reflect all adjustments, including normal recurring items, which are necessary to present fairly the results for interim periods. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the entire year. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with US GAAP have been omitted in accordance with the rules and regulations of the SEC; however, we believe that the disclosures are adequate to make information presented not misleading. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
	The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure since the balance sheet date of March 31, 2015 through the date on which the consolidated financial statements included in this Form 10-Q were issued.
	Principles of Consolidation
	The consolidated financial statements include the accounts of Aircastle and all of its subsidiaries. Aircastle consolidates seven Variable Interest Entities (“VIEs”) of which Aircastle is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.
	We consolidate VIEs in which we have determined that we are the primary beneficiary. We use judgment when deciding (a) whether an entity is subject to consolidation as a VIE, (b) who the variable interest holders are, (c) the potential expected losses and residual returns of the variable interest holders, and (d) which variable interest holder is the primary beneficiary. When determining which enterprise is the primary beneficiary, we consider (1) the entity’s purpose and design, (2) which variable interest holder has the power to direct the activities that most significantly impact the entity’s economic performance, and (3) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. When certain events occur, we reconsider whether we are the primary beneficiary of VIEs. We do not reconsider whether we are a primary beneficiary solely because of operating losses incurred by an entity.
	Use of Estimates
	The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. While Aircastle believes that the estimates and related assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates.
	Proposed Accounting Pronouncements
	In May 2013, the FASB issued re-exposure draft, “Leases” (the “Lease Re-ED”), which would replace the existing guidance in the Accounting Standards Codification (“ASC”) 840 (“ASC 840”), Leases. In March 2014, the FASB decided that the accounting for leases by lessors would basically remain unchanged from the concepts existing in current ASC 840 accounting. In addition, the FASB decided that a lessor should be precluded from recognizing selling profit and revenue at lease commencement for any sales-type or direct finance lease that does not transfer control of the underlying asset to the lessee. This requirement aligns the notion of what constitutes a sale in the lessor accounting guidance with that in the forthcoming revenue recognition standard, which evaluates whether a sale has occurred from the customer’s perspective. We anticipate that the final standard may have an effective date no earlier than 2018. We believe that when and if the proposed guidance becomes effective, it will not have a material impact on the Company’s consolidated financial statements.
	On May 28, 2014, the FASB and the International Accounting Standards Board (the “IASB”) (collectively, the Boards), jointly issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). Lease contracts within the scope of ASC 840, Leases, are specifically excluded from ASU No. 2014-09. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. The standard is effective for public entities beginning after December 15, 2017. The standard allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. The Company is currently evaluating the impacts of adoption and the implementation approach to be used.
	On August 27, 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40). The standard requires management of public companies to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern and, if so, disclose that fact. Management should evaluate whether there are conditions or events, considered in the aggregate, that raises substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or available to be issued, when applicable). The standard is effective for annual periods ending after December 15, 2016 and interim periods thereafter, and early adoption is permitted. We are currently evaluating the effect of the ASU on our consolidated financial statements and related disclosures.
	On April 7, 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. The guidance in the new standard is limited to the presentation of debt issuance costs and does not affect the recognition and measurement of debt issuance costs. The standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The new guidance will be applied on a retrospective basis. We are currently evaluating the effect of the ASU on our consolidated financial statements and related disclosures.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	Fair value measurements and disclosures require the use of valuation techniques to measure fair value that maximize the use of observable inputs and minimize use of unobservable inputs. These inputs are prioritized as follows:
	•	Level 1: Observable inputs such as quoted prices in active markets for identical assets or liabilities.
	•	Level 2: Inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities or market corroborated inputs.
	•	Level 3: Unobservable inputs for which there is little or no market data and which require us to develop our own assumptions about how market participants price the asset or liability.
	The valuation techniques that may be used to measure fair value are as follows:
	•	The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
	•	The income approach uses valuation techniques to convert future amounts to a single present amount based on current market expectation about those future amounts.
	•	The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost).
	The following tables set forth our financial assets and liabilities as of December 31, 2014 and March 31, 2015 that we measured at fair value on a recurring basis by level within the fair value hierarchy. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

	Liabilities:
	Derivative liabilities	$	3,121		$	—		$	3,121		$	—		Income
	Our cash and cash equivalents, along with our restricted cash and cash equivalents balances, consist largely of money market securities that are considered to be highly liquid and easily tradable. These securities are valued using inputs observable in active markets for identical securities and are therefore classified as Level 1 within our fair value hierarchy. Our interest rate derivatives included in Level 2 consist of United States dollar-denominated interest rate derivatives, and their fair values are determined by applying standard modeling techniques under the income approach to relevant market interest rates (cash rates, futures rates, swap rates) in effect at the period close to determine appropriate reset and discount rates and incorporates an assessment of the risk of non-performance by the interest rate derivative counterparty in valuing derivative assets and an evaluation of the Company’s credit risk in valuing derivative liabilities.
	For the three months ended March 31, 2014 and 2015, we had no transfers into or out of Level 3.
	We measure the fair value of certain assets and liabilities on a non-recurring basis, when US GAAP requires the application of fair value, including events or changes in circumstances that indicate that the carrying amounts of assets may not be recoverable. Assets subject to these measurements include our investment in an unconsolidated joint venture and aircraft. We account for our investment in an unconsolidated joint venture under the equity method of accounting and record impairment when its fair value is less than its carrying value. We record aircraft at fair value when we determine the carrying value may not be recoverable. Fair value measurements for aircraft in impairment tests are based on an income approach which uses Level 3 inputs, which include the Company’s assumptions and appraisal data as to future cash proceeds from leasing and selling aircraft.
	Aircraft Valuation
	During the first quarter of 2014, we impaired two aircraft, one Boeing 737-400, which was returned to us as scheduled by the lessee, and one Boeing 747-400 converted freighter, for which we agreed to an early lease termination with our customer which we refer to as “Transactional Impairments.” For these two aircraft, we recorded impairment charges totaling $18,263 and recorded maintenance revenue of $17,176 during the three months ended March 31, 2014.
	During the first quarter of 2015, we did not incur any impairment charges.
	Financial Instruments
	Our financial instruments, other than cash, consist principally of cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable, amounts borrowed under financings and interest rate derivatives. The fair value of cash, cash equivalents, restricted cash and cash equivalents, accounts receivable and accounts payable approximates the carrying value of these financial instruments because of their short-term nature.
	The fair value of our Securitization, which contains a third party credit enhancement, is estimated using a discounted cash flow analysis, based on our current incremental borrowing rates of borrowing arrangements that do not contain third party credit enhancements. The fair values of our ECA term financings and bank financings are estimated using a discounted cash flow analysis, based on our current incremental borrowing rates for similar types of borrowing arrangements. The fair value of our Senior Notes is estimated using quoted market prices.
	The carrying amounts and fair values of our financial instruments at December 31, 2014 and March 31, 2015 are as follows:
		December 31, 2014						March 31, 2015
		Carrying  Amount			Fair Value			Carrying  Amount			Fair Value

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities
	Aircastle consolidates seven VIEs of which it is the primary beneficiary. The operating activities of these VIEs are limited to acquiring, owning, leasing, maintaining, operating and, under certain circumstances, selling the 14 aircraft discussed below.
	Securitization
	Aircastle is the primary beneficiary of ACS Ireland 2, as we have both the power to direct the activities of the VIE that most significantly impacts the economic performance of such VIE and we bear the significant risk of loss and participate in gains through Class E-1 Securities. Although Aircastle has not guaranteed the ACS Ireland 2 debt, Aircastle wholly owns ACS Bermuda 2 which has fully and unconditionally guaranteed the ACS Ireland 2 VIE obligations. The activity that most significantly impacts the economic performance is the leasing of aircraft. Aircastle Advisor (Ireland) Limited (Aircastle’s wholly owned subsidiary) is the remarketing servicer and is responsible for the leasing of the aircraft. An Irish charitable trust owns 95% of the common shares of ACS Ireland 2. The Irish charitable trust’s risk is limited to its annual dividend of $2. At March 31, 2015, the assets of ACS Ireland 2 include six aircraft transferred into the VIE at historical cost basis in connection with Securitization No. 2.
	The assets of the ACS Ireland 2 as of March 31, 2015 are $168,500. The liabilities of the ACS Ireland 2, net of $40,351 Class E-1 Securities held by the Company, which is eliminated in consolidation, as of March 31, 2015 are $123,955.
	ECA Term Financings
	Aircastle, through various subsidiaries, each of which is owned by a charitable trust (such entities, collectively the “Air Knight VIEs”), has entered into eight different twelve-year term loans, which are supported by guarantees from Compagnie Francaise d’ Assurance pour le Commerce Exterieur, (“COFACE”), the French government sponsored export credit agency (“ECA”). We refer to these COFACE-supported financings as “ECA Term Financings.”
	Aircastle is the primary beneficiary of the Air Knight VIEs, as we have the power to direct the activities of the VIEs that most significantly impact the economic performance of such VIEs and we bear the significant risk of loss and participate in gains through a finance lease. The activity that most significantly impacts the economic performance is the leasing of aircraft of which our wholly owned subsidiary is the servicer and is responsible for managing the relevant aircraft. There is a cross collateralization guarantee between the Air Knight VIEs. In addition, Aircastle guarantees the debt of the Air Knight VIEs.
	The only assets that the Air Knight VIEs have on their books are financing leases that are eliminated in the consolidated financial statements and deferred financing costs. The related aircraft, with a net book value as of March 31, 2015 of $637,982 were included in our flight equipment held for lease. The consolidated debt outstanding of the Air Knight VIEs as of March 31, 2015 is $438,673.

Unsecured Debt Financings:

Senior Notes due 2022

On January 15, 2015, Aircastle Limited issued $500,000 aggregate principal amount of Senior Notes due 2022 (the "2022 Senior Notes") at par. The 2022 Senior Notes will mature on February 15, 2022 and bear interest at the rate of 5.50% per annum, payable semi-annually on February 15 and August 15 of each year, commencing on August 15, 2015. Interest accrues on the 2022 Senior Notes from January 15, 2015.

We may redeem the Senior Notes due 2022 at any time at a redemption price equal to (a) 100% of the principal amount of the notes redeemed, plus accrued and unpaid interest thereon to, but not including, the redemption date and (b) the sum of the present values of the remaining scheduled payments of principal and interest on the notes from the redemption date through the maturity date of the notes (computed using a discount rate equal to the Treasury Rate (as defined in the indenture governing the notes) as of such redemption date plus 50 basis points). In addition, on or before February 15, 2018, we may redeem up to 35% of the aggregate principal amount of the notes issued under the indenture at a redemption price equal to 105.50% plus accrued and unpaid interest thereon to, but not including, the redemption date, with the net proceeds of certain equity offerings. If the Company undergoes a change of control, it must offer to repurchase the Senior Notes due 2022 at 101% of the principal amount, plus accrued and unpaid interest. The Senior Notes due 2022 are not guaranteed by any of the Company's subsidiaries or any third party.

Revolving Credit Facility

On January 26, 2015, we increased the size of our Revolving Credit Facility from $450,000 to $600,000. The facility was undrawn as of March 31, 2015.

As of March 31, 2015, we are in compliance with all applicable covenants in all of our financings.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share
	We include all common shares granted under our incentive compensation plan which remain unvested (“restricted common shares”) and contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid (“participating securities”), in the number of shares outstanding in our basic earnings per share calculations using the two-class method. All of our restricted common shares are currently participating securities.
	Under the two-class method, earnings per common share is computed by dividing the sum of distributed earnings allocated to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, distributed and undistributed earnings are allocated to both common shares and restricted common shares based on the total weighted average shares outstanding during the period as follows:
		Three Months Ended March 31,
		2014			2015
	Weighted-average shares:
	Common shares outstanding	80,387,371			80,564,440

	Common shares outstanding	99.38	%		99.36	%
	Restricted common shares	0.62	%		0.64	%
	Total	100	%		100	%

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	Income taxes have been provided for based upon the tax laws and rates in countries in which our operations are conducted and income is earned. The Company received an assurance from the Bermuda Minister of Finance that it would be exempted from local income, withholding and capital gains taxes until March 2035. Consequently, the provision for income taxes relates to income earned by certain subsidiaries of the Company which are located in, or earn income in, jurisdictions that impose income taxes, primarily Singapore, Ireland and the United States.
	The sources of income from continuing operations before income taxes and earnings of unconsolidated equity method investment for the three months ended March 31, 2014 and 2015 were as follows:
		Three Months Ended March 31,
		2014			2015
	U.S. operations	$	765		$	380
	Non-U.S. operations	5,445			46,311
	Total	$	6,210		$	46,691
	All of our aircraft-owning subsidiaries that are recognized as corporations for U.S. tax purposes are non-U.S. corporations. These non-U.S. subsidiaries generally earn income from sources outside the United States and typically are not subject to U.S. federal, state or local income taxes unless they operate within the U.S., in which case they may be subject to federal, state and local income taxes. The aircraft owning subsidiaries resident in Ireland, Mauritius and Singapore are subject to tax in those respective jurisdictions.
	We have a U.S. based subsidiary which provides management services to our non-U.S. subsidiaries and is subject to U.S. federal, state and local income taxes. We also have Ireland and Singapore based subsidiaries which provide management services to our non-U.S. subsidiaries and are subject to tax in those respective jurisdictions.
	The consolidated income tax expense for the three months ended March 31, 2014 and 2015 was determined based upon estimates of the Company’s consolidated effective income tax rates for the years ending December 31, 2014 and 2015, respectively.
	The Company’s effective tax rate for the three months ended March 31, 2014 was 14.2% compared to 10.4% for the three months ended March 31, 2015. Movements in the effective tax rates are generally caused by changes in the proportion of the Company’s pre-tax earnings in taxable and non-tax jurisdictions.
	Differences between statutory income tax rates and our effective income tax rates applied to pre-tax income consisted of the following:
		Three Months Ended March 31,
		2014			2015

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Organization and Basis of Presentation	Aircastle is a holding company that conducts its business through subsidiaries. Aircastle directly or indirectly owns all of the outstanding common shares of its subsidiaries. The consolidated financial statements presented are prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”). We operate in one segment.
	The accompanying consolidated financial statements are unaudited and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting and, in our opinion, reflect all adjustments, including normal recurring items, which are necessary to present fairly the results for interim periods. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the entire year. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with US GAAP have been omitted in accordance with the rules and regulations of the SEC; however, we believe that the disclosures are adequate to make information presented not misleading. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
Principles of Consolidation	The consolidated financial statements include the accounts of Aircastle and all of its subsidiaries. Aircastle consolidates seven Variable Interest Entities (“VIEs”) of which Aircastle is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.
	We consolidate VIEs in which we have determined that we are the primary beneficiary. We use judgment when deciding (a) whether an entity is subject to consolidation as a VIE, (b) who the variable interest holders are, (c) the potential expected losses and residual returns of the variable interest holders, and (d) which variable interest holder is the primary beneficiary. When determining which enterprise is the primary beneficiary, we consider (1) the entity’s purpose and design, (2) which variable interest holder has the power to direct the activities that most significantly impact the entity’s economic performance, and (3) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. When certain events occur, we reconsider whether we are the primary beneficiary of VIEs. We do not reconsider whether we are a primary beneficiary solely because of operating losses incurred by an entity.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. While Aircastle believes that the estimates and related assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates.
New Accounting Pronouncements, Policy [Policy Text Block]	Proposed Accounting Pronouncements
	In May 2013, the FASB issued re-exposure draft, “Leases” (the “Lease Re-ED”), which would replace the existing guidance in the Accounting Standards Codification (“ASC”) 840 (“ASC 840”), Leases. In March 2014, the FASB decided that the accounting for leases by lessors would basically remain unchanged from the concepts existing in current ASC 840 accounting. In addition, the FASB decided that a lessor should be precluded from recognizing selling profit and revenue at lease commencement for any sales-type or direct finance lease that does not transfer control of the underlying asset to the lessee. This requirement aligns the notion of what constitutes a sale in the lessor accounting guidance with that in the forthcoming revenue recognition standard, which evaluates whether a sale has occurred from the customer’s perspective. We anticipate that the final standard may have an effective date no earlier than 2018. We believe that when and if the proposed guidance becomes effective, it will not have a material impact on the Company’s consolidated financial statements.
	On May 28, 2014, the FASB and the International Accounting Standards Board (the “IASB”) (collectively, the Boards), jointly issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). Lease contracts within the scope of ASC 840, Leases, are specifically excluded from ASU No. 2014-09. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. The standard is effective for public entities beginning after December 15, 2017. The standard allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. The Company is currently evaluating the impacts of adoption and the implementation approach to be used.
	On August 27, 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40). The standard requires management of public companies to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern and, if so, disclose that fact. Management should evaluate whether there are conditions or events, considered in the aggregate, that raises substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or available to be issued, when applicable). The standard is effective for annual periods ending after December 15, 2016 and interim periods thereafter, and early adoption is permitted. We are currently evaluating the effect of the ASU on our consolidated financial statements and related disclosures.
	On April 7, 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. The guidance in the new standard is limited to the presentation of debt issuance costs and does not affect the recognition and measurement of debt issuance costs. The standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The new guidance will be applied on a retrospective basis. We are currently evaluating the effect of the ASU on our consolidated financial statements and related disclosures.
