Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Financial Statement Preparation and Significant Accounting Policies	SUMMARY OF FINANCIAL STATEMENT PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Air Transport Services Group, Inc. is a holding company whose principal subsidiaries include an aircraft leasing company and two independently certificated airlines. The Company provides airline operations, aircraft leases, aircraft maintenance and other support services primarily to the cargo transportation and package delivery industries. Through the Company's subsidiaries, it offers a range of complementary services to delivery companies, freight forwarders, airlines and government customers. The Company's leasing subsidiary, Cargo Aircraft Management, Inc. (“CAM”), leases aircraft to each of the Company's airlines as well as to non-affiliated airlines and other lessees. The airlines, ABX Air, Inc. (“ABX”) and Air Transport International, Inc. (“ATI”), each have the authority, through their separate U.S. Department of Transportation ("DOT") and Federal Aviation Administration ("FAA") certificates, to transport cargo worldwide. ATI provides passenger transportation, primarily to the U.S. Military, using "combi" aircraft, which are certified to carry passengers as well as cargo on the main deck. The Company serves a base of concentrated customers who typically have a diverse line of international cargo traffic. The Company provides aircraft and airline operations to its customers, typically under contracts providing for a combination of aircraft, crews, maintenance and insurance ("ACMI") services. In addition to its airline operations and aircraft leasing services, the Company sells aircraft parts, provides aircraft and equipment maintenance services, and operates mail and package sorting facilities. Basis of Presentation The accompanying unaudited condensed interim consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America and such principles are applied on a basis consistent with the financial statements reflected in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 filed with the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations promulgated by the SEC related to interim financial statements. In the opinion of management, the accompanying financial statements contain all adjustments, including normal recurring adjustments, necessary for the fair presentation of the Company’s results of operations and financial position for the periods presented. Due to seasonal fluctuations, among other factors common to the airline industry, the results of operations for the periods presented are not necessarily indicative of the results of operations to be expected for the entire year or any interim period. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. The accounting estimates reflect the best judgment of management, but actual results could differ materially from those estimates. The accompanying condensed consolidated financial statements include the accounts of Air Transport Services Group, Inc. and its wholly-owned subsidiaries. Investments in an affiliate in which the Company has significant influence but does not exercise control are accounted for using the equity method of accounting. Using the equity method, the Company’s share of the nonconsolidated affiliate's income or loss is recognized in the consolidated statement of earnings and cumulative post-acquisition changes in the investment are adjusted against the carrying amount of the investment. Inter-company balances and transactions are eliminated. New Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, "Improvements to Employee Share-Based Payment Accounting," (“ASU 2016-09”) which addresses several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-9 is effective for annual reporting periods beginning after December 15, 2016 and earlier adoption is permitted. The new standard requires that an entity recognize all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement as discrete items in the reporting period in which they occur. Under the previous standard, excess tax benefits are recognized in additional paid-in capital and tax deficiencies are recognized either as an offset to accumulated excess tax benefits, or in the income statement. The Company elected to early adopt this standard in the quarter ended March 31, 2016. The impact of the early adoption resulted in the Company recording a tax benefit of $0.7 million within income tax expense for the three months ended March 31, 2016 related to the excess tax benefit on stock incentive awards that settled during the quarter ended March 31, 2016. The tax benefit for the nine months ended September 30, 2016 was $0.7 million . Prior to adoption of ASU 2016-09, this amount would have been recorded as an increase of additional paid-in capital. The tax benefit for the nine months ended September 30, 2015 would have been $0.4 million . The Company accounts for forfeitures as they occur. Under ASU 2016-09, excess tax benefits related to employee share-based payments are not reclassified from operating activities to financing activities in the statement of cash flows. The Company applied the effect of ASU 2016-09 to the presentation of excess tax benefits in the statement of cash flows, prospectively. Under ASU 2016-09, cash paid when withholding shares for tax withholding purposes are classified as a financing activity in the statement of cash flows. The Company has applied the effect of this change on prior period statements of cash flows retrospectively. The Company excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of our diluted earnings per share for the quarter ended September 30, 2016. This increased the diluted weighted average common shares outstanding by 151,421 shares. In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017 with earlier adoption permitted for reporting periods beginning after December 15, 2016. The Company is currently evaluating the methods of adoption allowed by the new standard and the effect the standard is expected to have on the Company's consolidated financial position, results of operations or cash flows and related disclosures. In April 2015, the FASB issued ASU 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). ASU 2015-03 requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying value of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by ASU 2015-03. The amendments in ASU 2015-03 are effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2015. As a result of the adoption of ASU 2015-03, the amounts of debt issuance costs were reclassified on the Company's balance sheets from other assets to long term debt. In July 2015, FASB issued ASU 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory" ("ASU 2015-11"). ASU 2015-11 more closely aligns the measurement of inventory in GAAP with the measurement of inventory in International Financial Reporting Standards ("IFRS"). The amendment in ASU 2015-11 is for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendment should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company does not expect the impact of adopting ASU 2015-11 to be material to the Company's financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" which will require the recognition of right to-use-assets and lease liabilities for leases previously classified as operating leases by lessees. The standard will take effect for annual reporting periods beginning after December 15, 2018, including interim reporting periods. Early application will be permitted for all entities. In addition, the FASB has decided to require a lessee to apply a modified retrospective transition approach for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements (the date of initial application). The modified retrospective approach would not require any transition accounting for leases that expired before the date of initial application. The FASB decided to not permit a full retrospective transition approach. The Company is currently evaluating the impact of the standard on its financial statements and disclosures. In January 2016, the FASB issued an Exposure Draft of a proposed ASU, "Compensation - Retirement Benefits (Topic 715) Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The proposed ASU would require an employer to report the service cost component of retiree benefits in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost would be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If adopted, the proposed standard would impact the Operating Income subtotal as reported in the Company's Consolidated Statement of Operations by excluding interest expense and investment returns components of retiree benefit expenses.

Significant Customers [Abstract]
Significant Customers	SIGNIFICANT CUSTOMERS DHL The Company's largest customer is DHL Network Operations (USA), Inc. and its affiliates ("DHL"). The Company has had long-term contracts with DHL since August 2003. Revenues from continuing operations performed for DHL were approximately 34% and 35% of the Company's consolidated revenues from continuing operations for the three and nine month periods ended September 30, 2016, respectively, compared to 47% and 49% for the corresponding periods of 2015. The Company’s balance sheets include accounts receivable with DHL of $5.0 million and $9.8 million as of September 30, 2016 and December 31, 2015, respectively. The Company leases Boeing 767 aircraft to DHL under both long-term and short-term lease agreements. Under a separate crew, maintenance and insurance (“CMI”) agreement, the Company operates Boeing 767 aircraft that DHL leases from the Company. Pricing for services provided through the CMI agreement is based on pre-defined fees, scaled for the number of aircraft operated and the number of flight crews provided to DHL for its U.S. network. The Company provides DHL with scheduled maintenance services for aircraft that DHL leases or owns. The Company also provides Boeing 767 and Boeing 757 air cargo transportation services for DHL through additional ACMI agreements in which the Company provides the aircraft, crews, maintenance and insurance under a single contract. Revenues generated from the ACMI agreements are typically based on hours flown. The Company also provides ground equipment, such as power units, air starts and related maintenance services to DHL under separate agreements. Amazon During September 2015, the Company began to operate a trial air network for Amazon Fulfillment Services, Inc. (“AFS”), a subsidiary of Amazon.com, Inc. (“Amazon”). The network grew to five freighter aircraft through first quarter of 2016 and included services for cargo handling and logistical support. On March 8, 2016, the Company entered into an Air Transportation Services Agreement (the “ATSA”) with AFS pursuant to which CAM will lease 20 Boeing 767 freighter aircraft to AFS, including 12 Boeing 767-200 freighter aircraft for a term of five years and eight Boeing 767-300 freighter aircraft for a term of seven years. The ATSA, which has a term of five years, also provides for the operation of those aircraft by the Company’s airline subsidiaries, and the performance of hub and gateway services by the Company's subsidiary LGSTX, Services Inc. ("LGSTX"). CAM owns all of the Boeing 767 aircraft that will be leased and operated under the ATSA. The Boeing 767-300 aircraft are being converted to freighter aircraft. The ATSA became effective on April 1, 2016. Revenues from continuing operations performed for AFS comprised approximately 31% and 24% of the Company's consolidated revenues from continuing operations for the three and nine month periods ending September 30, 2016, respectively. The Company’s balance sheets include accounts receivable with AFS of $18.2 million and $10.5 million as of September 30, 2016 and December 31, 2015, respectively. In conjunction with the execution of the ATSA, the Company and Amazon entered into an Investment Agreement and a Stockholders Agreement on March 8, 2016. The Investment Agreement calls for the Company to issue warrants in three tranches, which will grant Amazon the right to acquire up to 19.9% of the Company’s outstanding common shares as described below. The first tranche of warrants, issued upon execution of the Investment Agreement, grants Amazon the right to purchase approximately 12.81 million ATSG common shares, with the right to purchase 7.69 million common shares vesting upon issuance on March 8, 2016 and the right to purchase the remaining 5.12 million common shares vesting as the Company delivers additional aircraft leased under the ATSA, or as the Company achieves specified revenue targets in connection with the ATSA. The second tranche of warrants grants Amazon a right to purchase approximately 1.59 million ATSG common shares, and will be issued on March 8, 2018. The third tranche of warrants will be issued on September 8, 2020. The third tranche of warrants will grant Amazon the right to purchase such additional number of ATSG common shares as is necessary to bring Amazon’s ownership to 19.9% of the Company’s pre-transaction outstanding common shares measured on a GAAP-diluted basis, adjusted for share issuances and repurchases by the Company following the date of the Investment Agreement and after giving effect to the warrants granted. The exercise price of the warrants will be $9.73 per share, which represents the closing price of ATSG’s common shares on February 9, 2016. Each of the three tranches of warrants will be exercisable in accordance with its terms through March 8, 2021. The Company anticipates making available the common shares required for the underlying warrants through a combination of share repurchases and the issuance of additional shares. The Company’s accounting for the warrants has been determined in accordance with the financial reporting guidance for equity-based payments to non-employees and for financial instruments. The fair value of the warrants issued to Amazon as of March 8, 2016 was determined to be $4.89 per share using a Black-Scholes pricing model which considers the Company’s common stock price and various assumptions, such as the volatility of the Company’s common stock, the expected dividend yield, and the risk-free interest rate. The fair value of the 7.69 million vested warrants issued to Amazon was recorded as a lease incentive asset and is amortized against revenues over the duration of the aircraft leases. In March 2016, the value of these warrants was recorded in additional paid in capital, except for the fair value of 0.28 million warrants, which was recorded in liabilities because the Company did not have enough authorized shares to settle these warrants. On May 12, 2016, the Company’s stockholders approved an amendment to the Certificate of Incorporation of the Company at the annual meeting of stockholders to increase the number of authorized common shares and to approve the warrants in full as required under the rules of the Nasdaq Global Select Market. The stockholders' approval enabled features of the warrants that require the vested warrants of the first tranche and the warrants of the second and third tranches to be classified as financial derivatives as of May 12, 2016. Accordingly, the fair value of those warrants was measured and classified in liabilities on that date. As of September 30, 2016, the warrants were remeasured to fair value, resulting in a non-operating loss of $8.8 million and $3.5 million before the effect of income taxes, for the three and nine month periods ended September 30, 2016, respectively. As of June 30, 2016 and September 30, 2016, the Company's liabilities reflected 9.83 million warrants having a fair value of $5.81 and $6.71 per share, respectively, using a Black-Scholes pricing model. The Company's earnings in future periods will be impacted by the number of warrants granted, the re-measurements of warrant fair value, amortizations of the lease incentive asset and the related income tax effects. For income tax calculations, the value and timing of related tax deductions will likely differ from the guidance described above for financial reporting. U.S. Military A substantial portion of the Company's revenues is also derived from the U.S. Military.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS The Company’s money market funds and interest rate swaps are reported on the Company’s consolidated balance sheets at fair values based on market values from identical or comparable transactions. The fair value of the Company’s money market funds and interest rate swaps is based on observable inputs (Level 2) from comparable market transactions. The use of significant unobservable inputs (Level 3) was not necessary in determining the fair value of the Company’s financial assets and liabilities. The following table reflects assets and liabilities that are measured at fair value on a recurring basis (in thousands): As of September 30, 2016 Fair Value Measurement Using Total Level 1 Level 2 Level 3 Assets Cash equivalents—money market $ — $ 21,556 $ — $ 21,556 Total Assets $ — $ 21,556 $ — $ 21,556 Liabilities Interest rate swap $ — $ (438 ) $ — $ (438 ) Stock warrants (see note B) $ — $ (65,977 ) $ — $ (65,977 ) Total Liabilities $ — $ (66,415 ) $ — $ (66,415 ) As of December 31, 2015 Fair Value Measurement Using Total Level 1 Level 2 Level 3 Assets Cash equivalents—money market $ — $ 8,711 $ — $ 8,711 Total Assets $ — $ 8,711 $ — $ 8,711 Liabilities Interest rate swap $ — $ (499 ) $ — $ (499 ) Total Liabilities $ — $ (499 ) $ — $ (499 ) As a result of lower market interest rates compared to the stated interest rates of the Company’s fixed and variable rate debt obligations, the fair value of the Company’s debt obligations, based on Level 2 observable inputs, was approximately $2.1 million more than the carrying value, which was $449.1 million at September 30, 2016 . As of December 31, 2015, the fair value of the Company’s debt obligations was approximately $1.3 million more than the carrying value, which was $317.7 million . The non-financial assets, including goodwill, intangible assets and property and equipment are measured at fair value on a non-recurring basis.

On May 31, 2016, the Company executed an amendment to the Senior Credit Agreement (the "Sixth Credit Amendment"). The Sixth Credit Amendment extended the maturity of the term loan and revolving credit facility to May 30, 2021, increased the capacity of the Revolving credit facility by $100.0 million to $425.0 million and increased the accordion feature such that the Company can now draw up to an additional $100.0 million , subject to the lenders' consent. Under the terms of the Senior Credit Agreement, the Company is required to maintain collateral coverage equal to 150% of the outstanding balance of the term loan and the maximum capacity of the revolving credit facility or 175% of the outstanding balance of the term loan and the total funded revolving credit facility, whichever is less. The minimum collateral coverage which must be maintained is 50% of the outstanding balance of the term loan plus the revolving credit facility commitment, which was $425.0 million . The revolving credit facility has permitted additional indebtedness of $150.0 million . Each year, through May 6, 2019, the Company may request a one year extension of the final maturity date, subject to the lenders' consent. The balances of the unsubordinated term loan are net of debt issuance costs of $0.6 million and $0.5 million for the periods ending September 30, 2016 and December 31, 2015, respectively. The Senior Credit Agreement provides for the issuance of letters of credit on the Company's behalf. As of September 30, 2016, the unused revolving credit facility totaled $81.5 million , net of draws of $335.0 million and outstanding letters of credit of $8.5 million . Under the terms of the Senior Credit Agreement, interest rates are adjusted quarterly based on the Company's earnings before interest, taxes, depreciation and amortization expenses ("EBITDA"), its outstanding debt level and prevailing LIBOR or prime rates. At the Company's current debt-to-EBITDA ratio, the LIBOR-based financing for the unsubordinated term loan and revolving credit facility bear a variable interest rate of 2.28% and 2.28% , respectively. The aircraft loans are collateralized by five aircraft, and amortize monthly with a balloon payment of approximately 20% with maturities between 2016 and early 2018. The interest rates for the aircraft loans range from 6.74% to 7.06% per annum payable monthly. The Senior Credit Agreement is collateralized by certain of the Company's Boeing 767 and 757 aircraft that are not collateralized under aircraft loans. The Senior Credit Agreement contains covenants including, among other things, limitations on certain additional indebtedness, guarantees of indebtedness, as well as a total debt-to-EBITDA ratio and a fixed charge coverage ratio. The Senior Credit Agreement stipulates events of default, including unspecified events that may have material adverse effects on the Company. If an event of default occurs, the Company may be forced to repay, renegotiate or replace the Senior Credit Agreement. The Senior Credit Agreement limits the amount of dividends the Company can pay and the amount of common stock it can repurchase to $75.0 million during any calendar year, provided the Company's total debt-to-EBITDA ratio is under 2.75 times, after giving effect to the dividend or repurchase.

Purchase Commitments The Company has agreements with Israel Aerospace Industries Ltd. ("IAI") for the conversion of Boeing 767 passenger aircraft into a standard freighter configuration. The conversion primarily consists of the installation of a standard cargo door and loading system. At September 30, 2016, the Company owned seven Boeing 767-300 aircraft that were in or awaiting induction into the freighter modification process. The Company expects to complete the modification of two Boeing 767-300 aircraft during the remainder of 2016.

As of September 30, 2016, the Company's commitments to complete the conversions of aircraft it owns or has the contracts to purchase totaled $291.8 million . Additionally, the Company could incur a cancellation fee for part kits for any aircraft that is not inducted into conversion at IAI. Guarantees and Indemnifications Certain leases and agreements of the Company contain guarantees and indemnification obligations to the lessor, or one or more other parties that are considered reasonable and customary (e.g. use, tax and environmental indemnifications), the terms of which range in duration and are often limited. Such indemnification obligations may continue after expiration of the respective lease or agreement. Other In September 2015, the Company entered into a joint venture agreement to establish an express cargo airline serving multiple destinations within the People's Republic of China (including Hong Kong, Macau and Taiwan) and surrounding countries. The airline will be based in Tianjin, China with registered capital of 400 million RMB (US$63 million). It will be established pending the receipt of required governmental approvals and plans to commence flight operations by mid 2017. The Company may offer the new airline aircraft leases to build its fleet. The Company expects to contribute $16 million to the joint venture through 2017. The Company is currently a party to legal proceedings, including FAA enforcement actions, in various federal and state jurisdictions arising out of the operation of the Company's business. The amount of alleged liability, if any, from these proceedings cannot be determined with certainty; however, the Company believes that its ultimate liability, if any, arising from the pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are probable of assertion, taking into account established accruals for estimated liabilities, should not be material to the Company's financial condition or results of operations. Employees Under Collective Bargaining Agreements As of September 30, 2016 , the flight crewmember employees of ABX and ATI were represented by the labor unions listed below: Airline Labor Agreement Unit Percentage of the Company’s Employees ABX International Brotherhood of Teamsters 9.3% ATI Air Line Pilots Association 6.2%

Compensation and Retirement Disclosure [Abstract]
Pension and Other Post-Retirement Benefit Plans	PENSION AND OTHER POST-RETIREMENT BENEFIT PLANS Defined Benefit and Post-retirement Healthcare Plans ABX sponsors a qualified defined benefit pension plan for ABX crewmembers and a qualified defined benefit pension plan for a major portion of its other ABX employees that meet minimum eligibility requirements. ABX also sponsors non-qualified defined benefit pension plans for certain employees. These non-qualified plans are unfunded. Employees are no longer accruing benefits under any of the defined benefit pension plans. ABX also sponsors a post-retirement healthcare plan for its ABX employees, which is unfunded. Benefits for covered individuals terminate upon reaching age 65 under the post-retirement healthcare plans. The accounting and valuation for these post-retirement obligations are determined by prescribed accounting and actuarial methods that consider a number of assumptions and estimates. The selection of appropriate assumptions and estimates is significant due to the long time period over which benefits will be accrued and paid. The long-term nature of these benefit payouts increases the sensitivity of certain estimates of our post-retirement costs. The assumptions considered most sensitive in actuarially valuing ABX’s pension obligations and determining related expense amounts are discount rates and expected long-term investment returns on plan assets. Additionally, other assumptions concerning retirement ages, mortality and employee turnover also affect the valuations. Actual results and future changes in these assumptions could result in future costs significantly higher than those recorded in our results of operations. The Company's net periodic benefit costs for its defined benefit pension plans and post-retirement healthcare plans for both continuing and discontinued operations are as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, Pension Plans Post-Retirement Healthcare Plan Pension Plans Post-Retirement Healthcare Plan 2016 2015 2016 2015 2016 2015 2016 2015 Service cost $ — $ — $ 31 $ 44 $ — $ — 93 132 Interest cost 8,968 8,646 42 48 26,904 25,938 126 144 Expected return on plan assets (10,264 ) (11,020 ) — — (30,792 ) (33,060 ) — — Amortization of prior service cost — — (26 ) (136 ) — — (78 ) (408 ) Amortization of net (gain) loss 3,368 1,793 40 73 10,104 5,379 120 219 Net periodic benefit cost (gain) $ 2,072 $ (581 ) $ 87 $ 29 $ 6,216 $ (1,743 ) $ 261 $ 87 During the three and nine month periods ended September 30, 2016, the Company contributed $5.3 million and $6.3 million to the pension plans, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The provision for income taxes for interim periods is based on management's best estimate of the effective income tax rate expected to be applicable for the current year, plus any adjustments arising from changes in the estimated amount of taxable income related to prior periods. Income tax expense recorded through September 30, 2016 has been estimated utilizing a 38.5% rate based upon year-to-date income and projected results for the full year. Additionally, the Company recorded a discrete tax benefit of $0.7 million related to the conversion of employee stock awards during the first quarter of 2016. The final effective tax rate applied to 2016 will depend on the actual amount of non-deductible items, pre-tax book income generated by the Company for the full year and taxes related to the stock warrants granted to Amazon. The Company has operating loss carryforwards for U.S. federal income tax purposes. Management expects to utilize the loss carryforwards to offset federal income tax liabilities in the future. Due to the Company's deferred tax assets, including its loss carryforwards, management does not expect to pay federal income taxes until 2019 or later. The Company may, however, be required to pay alternative minimum taxes and certain state and local income taxes before then.

Derivative Instruments	DERIVATIVE INSTRUMENTS The Company's Senior Credit Agreement requires the Company to maintain derivative instruments for protection from fluctuating interest rates, for at least fifty percent of the outstanding balance of the term loan. Accordingly, the Company entered into interest rate swaps. The Company entered into a new interest rate swap in February of 2016 having an initial notional value of $48.8 million and a forward start date of May 9, 2016. Under this swap, the Company will pay a fixed rate of 1.09% and receive a floating rate that resets monthly based on LIBOR.

Stock-Based Compensation	STOCK-BASED COMPENSATION The Company's Board of Directors has granted stock incentive awards to certain employees and board members pursuant to a long term incentive plan which was approved by the Company's stockholders in May 2005 and in May 2015. Employees have been awarded non-vested stock units with performance conditions, non-vested stock units with market conditions and non-vested restricted stock. The restrictions on the non-vested restricted stock awards lapse at the end of a specified service period, which is typically approximately three years from the date of grant. Restrictions could lapse sooner upon a business combination, death, disability or after an employee qualifies for retirement. The non-vested stock units will be converted into a number of shares of Company stock depending on performance and market conditions at the end of a specified service period, lasting approximately three years. The performance condition awards will be converted into a number of shares of Company stock based on the Company's average return on invested capital during the service period. Similarly, the market condition awards will be converted into a number of shares depending on the appreciation of the Company's stock compared to the NASDAQ Transportation Index. Board members were granted time-based awards with vesting periods of approximately six or twelve months. The Company expects to settle all of the stock unit awards by issuing new shares of stock. The table below summarizes award activity.

The average grant-date fair value of each market condition award granted in 2016 was $19.65 . The market condition awards were valued using a Monte Carlo simulation technique, a risk-free interest rate of 1.1% and a volatility of 36.9% based on volatility over three years using daily stock prices. For the nine month periods ended September 30, 2016 and 2015, the Company recorded expense of $2.2 million and $2.0 million , respectively, for stock incentive awards. At September 30, 2016, there was $3.9 million of unrecognized expense related to the stock incentive awards that is expected to be recognized over a weighted-average period of 1.3 years. As of September 30, 2016, none of the awards were convertible, 338,919 units of the Board members time-based awards had vested and none of the outstanding shares of the restricted stock had vested. These awards could result in a maximum number of 1,544,219 additional outstanding shares of the Company’s common stock depending on service, performance and market results through December 31, 2018.

Earnings Per Share	COMMON STOCK AND EARNINGS PER SHARE Earnings per Share The calculation of basic and diluted earnings per common share follows (in thousands, except per share amounts): Three Months Ended Nine Months Ended September 30, September 30, 2016 2015 2016 2015 Numerator: Earnings from continuing operations $ 2,116 $ 6,347 $ 21,815 $ 25,812 Weighted-average shares outstanding - basic 59,379 64,239 62,084 64,411 Common equivalent shares: Effect of stock-based compensation awards 904 932 1,940 930 Weighted-average shares outstanding - diluted 60,283 65,171 64,024 65,341 Basic earnings per share from continuing operations $ 0.04 $ 0.10 $ 0.35 $ 0.40 Diluted earnings per share from continuing operations $ 0.04 $ 0.10 $ 0.34 $ 0.40 The determination of diluted earnings per share in accordance with GAAP requires the adjustment to the numerator, of the fair value re-measurement of the stock warrants recorded as a liability (see Note B) when the inclusion of the warrants has a dilutive effect on earnings per share. The dilutive effect of the stock warrants on the weighted-average shares outstanding is calculated using the treasury stock method. Under this method, the number of diluted shares is determined by dividing the assumed proceeds of the warrants by the average stock price during the period and comparing that amount with the number of warrants outstanding. The assumed proceeds are determined by multiplying the number of shares underlying the warrants by the strike price. The number of equivalent shares that were not included in weighted average shares outstanding assuming dilution, because their effect would have been anti-dilutive, was 3.3 million and 1.1 million for the three and nine month periods ended September 30, 2016 , respectively. The underlying warrants as of September 30, 2016, could result in 9.8 million additional outstanding shares of the Company’s common stock if the warrants are settled by tendering cash. Purchase of Common Stock The Company's Board of Directors has authorized management to repurchase outstanding common stock of the Company from time to time on the open market or in privately negotiated transactions. The authorization does not require the Company to repurchase a specific number of shares and the Company may terminate the repurchase program at any time. Upon the retirement of common stock repurchased, the excess purchase price over the par value for retired shares of common stock is recorded to additional paid-in-capital. On July 5, 2016 the Company purchased 3,825,554 shares of the Company's common stock from its largest shareholder, Red Mountain Partners, L.P., a fund that is affiliated with Red Mountain Capital Partners, LLC (“Red Mountain”), a related party, for an aggregate purchase price of $50.0 million . The purchase price was previously negotiated based on the closing price of the shares on June 20, 2016. The purchase price of $13.07 per share represents a large block discount of 2.5% and 6.2%, respectively, from the volume-weighted average prices of $13.41 for the 10 trading days and $13.93 for the 60 trading days prior to June 20, 2016.

The Company's other activities, which include contracts with the U.S. Postal Service ("USPS"), the sale of aircraft parts and maintenance services, hub management services, facility and ground equipment maintenance services, the sales of aviation fuel and management services for workers' compensation, while managed separately, are not large enough to constitute reportable segments and are combined in “All other” with inter-segment profit eliminations. Inter-segment revenues are valued at arms-length market rates. Cash, cash equivalents and deferred tax assets are reflected in Assets - All other below.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed interim consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America and such principles are applied on a basis consistent with the financial statements reflected in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 filed with the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations promulgated by the SEC related to interim financial statements. In the opinion of management, the accompanying financial statements contain all adjustments, including normal recurring adjustments, necessary for the fair presentation of the Company’s results of operations and financial position for the periods presented. Due to seasonal fluctuations, among other factors common to the airline industry, the results of operations for the periods presented are not necessarily indicative of the results of operations to be expected for the entire year or any interim period. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. The accounting estimates reflect the best judgment of management, but actual results could differ materially from those estimates. The accompanying condensed consolidated financial statements include the accounts of Air Transport Services Group, Inc. and its wholly-owned subsidiaries. Investments in an affiliate in which the Company has significant influence but does not exercise control are accounted for using the equity method of accounting. Using the equity method, the Company’s share of the nonconsolidated affiliate's income or loss is recognized in the consolidated statement of earnings and cumulative post-acquisition changes in the investment are adjusted against the carrying amount of the investment. Inter-company balances and transactions are eliminated.
New Accounting Pronouncements	New Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, "Improvements to Employee Share-Based Payment Accounting," (“ASU 2016-09”) which addresses several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-9 is effective for annual reporting periods beginning after December 15, 2016 and earlier adoption is permitted. The new standard requires that an entity recognize all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement as discrete items in the reporting period in which they occur. Under the previous standard, excess tax benefits are recognized in additional paid-in capital and tax deficiencies are recognized either as an offset to accumulated excess tax benefits, or in the income statement. The Company elected to early adopt this standard in the quarter ended March 31, 2016. The impact of the early adoption resulted in the Company recording a tax benefit of $0.7 million within income tax expense for the three months ended March 31, 2016 related to the excess tax benefit on stock incentive awards that settled during the quarter ended March 31, 2016. The tax benefit for the nine months ended September 30, 2016 was $0.7 million . Prior to adoption of ASU 2016-09, this amount would have been recorded as an increase of additional paid-in capital. The tax benefit for the nine months ended September 30, 2015 would have been $0.4 million . The Company accounts for forfeitures as they occur. Under ASU 2016-09, excess tax benefits related to employee share-based payments are not reclassified from operating activities to financing activities in the statement of cash flows. The Company applied the effect of ASU 2016-09 to the presentation of excess tax benefits in the statement of cash flows, prospectively. Under ASU 2016-09, cash paid when withholding shares for tax withholding purposes are classified as a financing activity in the statement of cash flows. The Company has applied the effect of this change on prior period statements of cash flows retrospectively. The Company excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of our diluted earnings per share for the quarter ended September 30, 2016. This increased the diluted weighted average common shares outstanding by 151,421 shares. In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017 with earlier adoption permitted for reporting periods beginning after December 15, 2016. The Company is currently evaluating the methods of adoption allowed by the new standard and the effect the standard is expected to have on the Company's consolidated financial position, results of operations or cash flows and related disclosures. In April 2015, the FASB issued ASU 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). ASU 2015-03 requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying value of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by ASU 2015-03. The amendments in ASU 2015-03 are effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2015. As a result of the adoption of ASU 2015-03, the amounts of debt issuance costs were reclassified on the Company's balance sheets from other assets to long term debt. In July 2015, FASB issued ASU 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory" ("ASU 2015-11"). ASU 2015-11 more closely aligns the measurement of inventory in GAAP with the measurement of inventory in International Financial Reporting Standards ("IFRS"). The amendment in ASU 2015-11 is for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendment should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company does not expect the impact of adopting ASU 2015-11 to be material to the Company's financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" which will require the recognition of right to-use-assets and lease liabilities for leases previously classified as operating leases by lessees. The standard will take effect for annual reporting periods beginning after December 15, 2018, including interim reporting periods. Early application will be permitted for all entities. In addition, the FASB has decided to require a lessee to apply a modified retrospective transition approach for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements (the date of initial application). The modified retrospective approach would not require any transition accounting for leases that expired before the date of initial application. The FASB decided to not permit a full retrospective transition approach. The Company is currently evaluating the impact of the standard on its financial statements and disclosures. In January 2016, the FASB issued an Exposure Draft of a proposed ASU, "Compensation - Retirement Benefits (Topic 715) Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The proposed ASU would require an employer to report the service cost component of retiree benefits in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost would be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If adopted, the proposed standard would impact the Operating Income subtotal as reported in the Company's Consolidated Statement of Operations by excluding interest expense and investment returns components of retiree benefit expenses.
