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, e-commerce operators, freight forwarders, airlines and government customers. 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. 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 Company provides aircraft and airline operations to its customers, typically under contracts providing for a combination of aircraft, crews, maintenance and insurance ("ACMI") services. The Company serves a base of concentrated customers who have a diverse line of international cargo traffic. DHL Network Operations (USA), Inc. and its affiliates, “DHL,” is the Company's largest customer. 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. In addition to its airline operations and aircraft leasing services, the Company sells aircraft parts, provides aircraft and equipment maintenance services, and operates mail sorting facilities for the U.S. Postal Service (“USPS”). 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 information reflected in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 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. 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 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. Early adoption is permitted. The Company does not expect the impact of adopting ASU 2015-03 to be material to the Company’s financial statements and related disclosures.

Significant Customers [Abstract]
Significant Customers	SIGNIFICANT CUSTOMERS DHL The Company's largest customer is DHL. The Company has had long-term contracts with DHL since August 2003. Commencing March 31, 2010, the Company and DHL executed commercial agreements under which DHL leases Boeing 767 freighter aircraft from CAM and ABX operates those aircraft under a separate crew, maintenance and insurance (“CMI”) agreement. The initial term of the CMI agreement was five years, ending March 31, 2015 while the terms of the aircraft leases were seven years. Effective April 1, 2015, the Company and DHL amended and restated the CMI agreement ("restated CMI agreement") under which ABX continues to operate Boeing 767 aircraft for DHL through March of 2019 and the Boeing 767 aircraft lease terms were extended through March of 2019. Pricing for services provided through the restated CMI agreement is based on pre-defined fees scaled for the number of aircraft hours flown, aircraft scheduled and flight crews provided to DHL for its U.S. network. During the third quarter of 2015, CAM leased 16 Boeing 767 aircraft to DHL and ABX operated them under the restated CMI agreement for DHL's network. The Company has other agreements to provide additional air cargo transportation services to DHL. During the third quarter of 2015, ATI operated four CAM-owned Boeing 757 aircraft for DHL's network through ACMI agreements in which the Company provides the aircraft, crews, maintenance and insurance under a single contract. Additionally, ATI operated a Boeing 757 aircraft, supplied by DHL, for DHL's network. Revenues generated from the ACMI agreements are typically based on hours flown during the period. The Company also provides maintenance services to DHL for ground equipment, such as power units and air starts under separate agreements. Revenues from continuing operations performed for DHL were approximately 47% and 49% of the Company's consolidated revenues from continuing operations for the three and nine month periods ended September 30, 2015, respectively, compared to 54% and 56% for the corresponding periods of 2014. The Company’s balance sheets include accounts receivable with DHL of $5.6 million and $12.2 million as of September 30, 2015 and December 31, 2014, respectively. U.S. Military A substantial portion of the Company's revenues are also derived from the U.S. Military. The U.S. Military awards flights to U.S. certificated airlines through annual contracts and through temporary "expansion" routes. Revenues from services performed for the U.S. Military were approximately 17% and 17% of the Company's total revenues from continuing operations for the three and nine month periods ended September 30, 2015, respectively, compared to 17% and 17% for the corresponding periods of 2014. The Company's balance sheets included accounts receivable with the U.S. Military of $7.4 million and $6.0 million as of September 30, 2015 and December 31, 2014, respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangibles	GOODWILL, ACQUIRED INTANGIBLES AND EQUITY INVESTMENTS The Company has one reporting unit that has goodwill, CAM. The carrying amounts of goodwill are as follows (in thousands): CAM Total Carrying value as of December 31, 2014 $ 34,395 $ 34,395 Carrying value as of September 30, 2015 $ 34,395 $ 34,395 The Company's intangible assets relate to the ACMI Services segment and are as follows (in thousands): Customer Airline Relationships Certificates Total Carrying value as of December 31, 2014 $ 1,615 $ 3,000 $ 4,615 Amortization (211 ) — (211 ) Carrying value as of September 30, 2015 $ 1,404 $ 3,000 $ 4,404 The customer relationship intangible amortizes through 2020. The airline certificates have an indefinite life and therefore are not amortized. In January 2014, the Company acquired a 25 percent equity interest in West Atlantic AB of Gothenburg, Sweden ("West"). West, through its two airlines, Atlantic Airlines Ltd. and West Air Sweden AB, operates a fleet of approximately 45 aircraft primarily in Europe. West operates its aircraft on behalf of European regional mail carriers and express logistics providers. The airlines operate a combined fleet of British Aerospace ATPs, Bombardier CRJ-200-PFs, Boeing 737 and Boeing 767 aircraft. The Company has significant influence, but does not exercise control, over West. Accordingly, the investment in West is accounted for using the equity method of accounting and was initially recognized at cost. The Company’s carrying value of West was $12.9 million and $13.8 million at September 30, 2015 and December 31, 2014, respectively, including $5.5 million of excess purchase price over the Company's proportional fair value of West's net assets in January of 2014. The carrying value is reflected in “Other Assets” in the Company’s consolidated balance sheets.

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 are 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, 2015 Fair Value Measurement Using Total Level 1 Level 2 Level 3 Assets Cash equivalents—money market $ 20 $ 3,079 $ — $ 3,099 Total Assets $ 20 $ 3,079 $ — $ 3,099 Liabilities Interest rate swaps $ — $ (1,072 ) $ — $ (1,072 ) Total Liabilities $ — $ (1,072 ) $ — $ (1,072 ) As of December 31, 2014 Fair Value Measurement Using Total Level 1 Level 2 Level 3 Assets Cash equivalents—money market $ 20 $ 2,306 $ — $ 2,326 Total Assets $ 20 $ 2,306 $ — $ 2,326 Liabilities Interest rate swaps $ — $ (1,419 ) $ — $ (1,419 ) Total Liabilities $ — $ (1,419 ) $ — $ (1,419 ) 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 $0.3 million less than the carrying value, which was $309.3 million at September 30, 2015 . As of December 31, 2014, the fair value of the Company’s debt obligations was approximately $2.5 million more than the carrying value, which was $344.1 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 8, 2015, the Company executed an amendment to the Senior Credit Agreement (the "Fifth Credit Amendment"). The Fifth Credit Amendment extended the maturity of the term loan and revolving credit facility to May 5, 2020, increased the capacity of the Revolving credit facility by $50.0 million to $325.0 million , increased the permitted additional indebtedness by $50.0 million to $150.0 million , and retained the accordion feature whereby the Company can draw up to an additional $50.0 million subject to the lenders' consent. Under the amended terms of the Senior Credit Agreement, the Company is required to maintain collateral coverage equal to 150% of the outstanding balances 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 $325.0 million as of May 8, 2015. Each year, through May 6, 2019, the Company may request a one year extension of the final maturity date, subject to the lenders' consent. 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 1.95% and 1.95% , respectively. The Credit Amendment did not affect the EBITDA based pricing or covenants of the Senior Credit Agreement. The Senior Credit Agreement provides for the issuance of letters of credit on the Company's behalf. As of September 30, 2015, the unused revolving credit facility totaled $151.7 million , net of draws of $165.0 million and outstanding letters of credit of $8.3 million . The aircraft loans are collateralized by six aircraft, and amortize monthly with a balloon payment of approximately 20% with maturities between 2016 and early 2018. Interest rates range from 6.74% to 7.36% 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 $50.0 million during any calendar year, provided the Company's total debt to EBITDA ratio is under 2.5 times, after giving effect to the dividend or repurchase.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Lease Commitments The Company leases portions of the air park in Wilmington, Ohio, under long-term lease agreements with a regional port authority. The leased facilities include corporate offices, 310,000 square feet of maintenance hangars and a 100,000 square foot component repair shop at the air park. ABX also has the non-exclusive right to use the airport, which includes one active runway, taxi ways and ramp space. Additionally, the Company leases certain equipment and airport facilities, office space and maintenance facilities at locations outside of the airpark in Wilmington. 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. Brussels Noise Ordinance The Brussels Instituut voor Milieubeheer ("BIM"), a governmental authority in the Brussels-Capital Region of Belgium that oversees the enforcement of environmental matters, imposed four separate administrative penalties on ABX in the approximate aggregate amount of €0.4 million ( $0.4 million ) for numerous alleged violations of an ordinance limiting the noise caused by aircraft overflying the Brussels-Capital Region (which is located near the Brussels Airport) during the period from May 2009 through December 2010. ABX has exhausted its appeals with respect to all four of the administrative penalties. The ordinance in question is controversial for the reason that it was adopted by the Brussels-Capital Region and is more restrictive than the noise limitations in effect in the Flemish Region, which is where the Brussels Airport is located. Numerous airlines have been levied fines under the ordinance, which has been the subject of several court cases in the Belgian courts, including with respect to demands for payment. In October 2015, ABX paid approximately $0.4 million in satisfaction of the fines. Other In September 2015, we entered into a joint venture agreement to establish an express cargo airline serving multiple destinations within the Peoples Republic of China (including Hong Kong, Macau and Taiwan) and surrounding countries. The airline will be named United Star Express Airlines Co. Ltd., and will be based in 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 in mid-2016. We expect to contribute $16 million to the joint venture over the next nine months. In addition to the foregoing matters, we are also 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, we believe that the Company's 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 our financial condition or results of operations. Employees Under Collective Bargaining Agreements As of September 30, 2015 , 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 10.2% ATI Air Line Pilots Association 6.0%

Pension and Other Post-Retireme

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 2015 2014 2015 2014 2015 2014 2015 2014 Service cost $ — $ — $ 44 $ 60 $ — $ — $ 132 $ 180 Interest cost 8,646 9,879 48 71 25,938 29,637 144 213 Expected return on plan assets (11,020 ) (11,528 ) — — (33,060 ) (34,584 ) — — Amortization of prior service cost — — (136 ) (872 ) — — (408 ) (2,616 ) Amortization of net (gain) loss 1,793 (1 ) 73 80 5,379 (2 ) 219 240 Net periodic benefit cost (gain) $ (581 ) $ (1,650 ) $ 29 $ (661 ) $ (1,743 ) $ (4,949 ) $ 87 $ (1,983 ) During the three and nine month periods ended September 30, 2015, the Company contributed $5.3 million and $6.2 million to the pension plans. The Company expects to contribute an additional $0.3 million during the remainder of 2015.

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 taxes recorded through September 30, 2015 have been estimated utilizing a 38.6% rate based upon year-to-date income and projected results for the full year. The final effective tax rate applied to 2015 will depend on the actual amount of pre-tax book income generated by the Company for the full year. 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 2017 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 term loan. Accordingly, the Company entered into interest rate swaps, which are described in the table below (in thousands): September 30, 2015 December 31, 2014 Expiration Date Stated Interest Rate Notional Amount Market Value (Liability) Notional Amount Market Value (Liability) May 9, 2016 2.020 % 52,500 (507 ) 58,125 (1,071 ) June 30, 2017 1.183 % 52,500 (565 ) 58,125 (348 ) The outstanding interest rate swaps are not designated as hedges for accounting purposes. The effects of future fluctuations in LIBOR interest rates on derivatives held by the Company will result in the recording of unrealized gains and losses into the statement of operations. The Company recorded unrealized gain on derivatives of $0.3 million and $1.0 million for the nine month periods ending September 30, 2015 and 2014, respectively. The liability for outstanding derivatives is recorded in other liabilities and in accrued expenses.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
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. 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. Nine Months Ended September 30, 2015 September 30, 2014 Number of Awards Weighted average grant-date fair value Number of Awards Weighted average grant-date fair value Outstanding at beginning of period 1,406,550 $ 6.21 1,477,762 $ 5.83 Granted 390,200 9.61 467,567 7.52 Converted (263,791 ) 6.42 (186,179 ) 7.50 Expired (1,600 ) 10.11 (4,300 ) 7.64 Forfeited (13,800 ) 7.36 (17,800 ) 6.26 Outstanding at end of period 1,517,559 $ 7.03 1,737,050 $ 6.10 Vested 329,059 $ 5.61 415,550 $ 5.28 The average grant-date fair value of each performance condition award, non-vested restricted stock award and time-based award granted by the Company in 2015 was $9.22 , the fair value of the Company’s stock on the date of grant. The average grant-date fair value of each market condition award granted in 2015 was $10.99 . The market condition awards were valued using a Monte Carlo simulation technique, a risk-free interest rate of 0.9% and a volatility of 41.5% based on volatility over three years using daily stock prices. For the nine month periods ended September 30, 2015 and 2014, the Company recorded expense of $2.0 million and $2.1 million , respectively, for stock incentive awards. At September 30, 2015, there was $3.5 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, 2015, none of the awards were convertible, 329,059 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 1,820,159 additional outstanding shares of the Company’s common stock depending on service, performance and market results through December 31, 2017.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION The Company operates in two reportable segments. The CAM segment consists of the Company's aircraft leasing operations and its segment earnings includes an allocation of interest expense. The ACMI Services segment consists of the Company's airline operations, including the CMI agreement with DHL as well as ACMI and charter service agreements that the Company has with other customers. Due to the similarities among the Company's airline operations, the airline operations are aggregated into a single reportable segment, ACMI Services. The Company's other activities, which include contracts with the USPS, the sale of aircraft parts and maintenance services, facility and ground equipment maintenance services and management services for workers' compensation do not 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 information reflected in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 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. 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 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. Early adoption is permitted. The Company does not expect the impact of adopting ASU 2015-03 to be material to the Company’s financial statements and related disclosures.
