| Organization and Operations |
The Company Mesa Air Group, Inc. (“Mesa” or the “Company”) is a holding company whose principal subsidiary operates as a regional air carrier, providing scheduled passenger service. As of June 30, 2018, the Company served 115 cities in 38 states, the District of Columbia, Canada, Mexico, and the Bahamas and operated a fleet of 145 aircraft with approximately 600 daily departures. The Company’s airline operations are conducted by its regional airline subsidiary, Mesa Airlines, Inc. (“Mesa Airlines”), providing services to major air carriers under capacity purchase agreements. Mesa Airlines operates as American Eagle under a capacity purchase agreement with American Airlines, Inc. (“American”) and as United Express under a capacity purchase agreement with United Airlines, Inc. (“United”). All of the Company’s condensed consolidated contract revenues for three months ended June 30, 2018 and 2017 and nine months ended June 30, 2018 and 2017 were derived from operations associated with these two capacity purchase agreements. The financial arrangements between the Company and its major airline partners involve a revenue-guarantee arrangement whereby the major airline pays a monthly guaranteed amount for each aircraft under contract, a fixed fee for each block hour and flight flown and reimbursement of certain direct operating expenses in exchange for providing regional flying. The major airline partners also pay certain expenses directly to suppliers, such as fuel, ground operations and certain landing fees. Under the terms of these capacity purchase agreements, the major airline controls route selection, pricing and seat inventories, thereby reducing the Company’s exposure to fluctuations in passenger traffic, fare levels, and fuel prices. On August 14, 2018, the Company completed an initial public offering (“IPO”) of its common stock, in which it issued and sold 9,630,000 shares of common stock at a public offering price of $12.00 per share, resulting in gross proceeds to the Company of approximately $115.6 million. Additionally, in connection with the IPO, the Company granted the underwriters an option to purchase up to an additional 777,833 shares of common stock at the same price, which has not been exercised as of September 4, 2018, the issuance date of the interim financial statements. As part of the IPO, stock appreciation rights (“SARs”) previously issued under the Mesa Air Group, Inc. Amended and Restated Stock Appreciation Rights Plan (the “SAR Plan”), which settled only in cash, were cancelled and exchanged for an aggregate of 1,266,034 shares of restricted common stock under the Company’s 2018 Equity Incentive Plan (the “2018 Plan”) (see note 12), of which 966,022 were fully vested upon issuance and are included in the number of shares of common stock outstanding after the IPO. Of the 966,022 fully vested shares, 314,198 shares were retained by the Company to satisfy tax withholding obligations, resulting in a net issuance of 651,824 shares. American Capacity Purchase Agreement As of June 30, 2018, the Company operated 64 CRJ-900 aircraft for American under a capacity purchase agreement. Unless otherwise extended or amended, the capacity purchase agreement for the aircraft expires between 2021 and 2025. In exchange for providing flights and all other services under the agreement, the Company receives a fixed monthly minimum amount per aircraft, plus certain additional amounts based upon the number of flights and block hours (the number of hours during which the aircraft is in revenue service, measured from the time of gate departure before take-off until the time of gate arrival at the destination) flown during the month. In addition, the Company may also receive incentives or pay penalties based upon the Company’s operational performance, including controllable on-time departure and controllable completion percentages. American also reimburses the Company for the actual amount incurred for certain items such as passenger liability and hull insurance, and aircraft property taxes. In addition, American also provides, at no cost to the Company, certain ground handling and customer service functions, as well as airport-related facilities and fuel. The Company also receives a monthly profit margin payment from American based on the number of aircraft operating. The capacity purchase agreement is subject to early termination for cause under specified circumstances and subject to the Company’s right to cure under certain conditions. American has a 10.7% ownership interest in the Company, calculated on a fully-diluted basis. The related party amounts presented on the condensed consolidated balance sheets and statements of operations pertain to American.
United Capacity Purchase Agreement As of June 30, 2018, the Company operated 20 CRJ-700 and 60 E-175 aircraft for United under a capacity purchase agreement. Subject to certain early termination rights, the capacity purchase agreement for each of the 20 CRJ-700 aircraft expires between August and December 2019. Subject to early termination rights, the capacity purchase agreement for 30 of the E-175 aircraft (owned by United) expires between June 2019 and August 2020, subject to United’s right to extend for four additional two-year terms (maximum of eight years). Subject to early termination rights, the capacity purchase agreement for 18 of the E-175aircraft (owned by Mesa) expires between January 2028 and November 2028. During fiscal 2017, the Company and United expanded the capacity purchase agreement to include an additional 12 E-175 aircraft (purchased by United) with the aircraft entering service through January 2018 for five-year terms, subject to United’s right to extend for four additional two-year terms (maximum of eight years). In exchange for performing the flight services under such agreement, the Company receives from United a fixed monthly minimum amount per aircraft, plus certain additional amounts based upon the number of flights and block hours flown during the month. Additionally, certain costs incurred by the Company in performing the flight services are “pass-through” costs, whereby United agrees to reimburse the Company for the actual amounts incurred for the following items: property tax per aircraft, landing fees, and additionally for the E-175 aircraft owned by United, heavy airframe and engine maintenance, landing gear, APUs and component maintenance. The Company also receives a profit margin based upon certain reimbursable costs under the agreement, as well as its operational performance in addition to a fixed profit margin. The capacity purchase agreement is also subject to early termination for cause under specified circumstances and subject to the Company’s right to cure under certain circumstances. In February 2018, the Company mutually agreed with United to temporarily remove two aircraft from service under its United capacity purchase agreement until the Company was able to fully staff flight operations. During the temporary removal, the Company agreed to pay the lease costs associated with the two E-175aircraft, which totaled $1.9 million as of June 30, 2018. In June 2018, the Company mutually agreed with United to place two E-175 aircraft back into service under the United capacity purchase agreement that were temporarily removed. |

| Summary of Significant Accounting Policies |
Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its wholly owned operating subsidiaries. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). All intercompany accounts and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been derived from, and should be read in conjunction with, the Company’s audited consolidated financial statements and notes thereto as of and for the year ended September 30, 2017 included in the Company’s Registration Statement on Form S-1, FileNo. 333-226173 on file with the U.S. Securities and Exchange Commission (the “SEC”). There have not been any significant changes to the Company’s significant accounting policies during the nine months ended June 30, 2018, except for the valuation of stock compensation at fair value. Information and footnote disclosures normally included in financial statements have been condensed or omitted in these condensed consolidated financial statements pursuant to the rules and regulations of the SEC and GAAP. These condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the results of operations for the interim periods presented. The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and may remain an emerging growth company until the last day of the fiscal year following the fifth anniversary of the IPO, subject to specified conditions. The JOBS Act provides that an emerging growth company can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company has elected to “opt out” of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements. Actual results could differ from those estimates.
Rental Income The amount deemed to be rental income for the three months ended June 30, 2018 and 2017 was $53.5 million and $54.5 million, respectively, and for the nine months ended June 30, 2018 and 2017 was $162.0 million and $163.0 million, respectively. Rental income has been included in contract revenue on the Company’s condensed consolidated statements of operations. The Company has not separately stated aircraft rental income and aircraft rental expense in the condensed consolidated statements of operations since the use of the aircraft is not a separate activity of the total service provided. Maintenance Expense The Company operates under a Federal Aviation Administration (“FAA”) approved continuous inspection and maintenance program. The Company uses the direct expense method of accounting for its maintenance of regional jet engine overhauls, airframe, landing gear, and normal recurring maintenance wherein the expense is recognized when the maintenance work is completed, or over the period of repair, if materially different. For leased aircraft, the Company is subject to lease return provisions that require a minimum portion of the “life” of an overhaul be remaining on the engine at the lease return date. The Company estimates the cost of maintenance lease return obligations and accrues such costs over the remaining lease term when the expense is probable and can be reasonably estimated. Engine overhaul expense totaled $13.1 million and $8.4 million for the three months ended June 30, 2018 and 2017, respectively, of which $4.6 million and $0 was pass-through expense and $46.2 million and $53.5 million for the nine months ended June 30, 2018 and 2017, respectively, of which $9.8 million and $0 was pass-through expense. Airframe check expense totaled $6.3 million and $6.7 million for the three months ended June 30, 2018 and 2017, respectively, of which $1.6 million and $2.2 million was pass-through expense and $19.8 million and $16.9 million for the nine months ended June 30, 2018 and 2017, respectively, of which $7.3 million and $2.6 million was pass-through expense. Pursuant to the United capacity purchase agreement, United reimburses the Company for heavy maintenance on certain E-175 aircraft. Those reimbursements are included in pass-through and other revenue. See Note 1: “Organization and Operations” for further information. Change in Accounting Policy Stock Appreciation Rights (“SARs”) and Phantom Stock historically were accounted for as liability compensatory awards under ASC 710, Compensation – General, valued using the intrinsic value method, as permitted by ASC 718 for nonpublic entities. Upon becoming a public company, as defined in ASC 718, in the third quarter of 2018, the Company was required to change its methodology for valuing the SARs and Phantom Stock. While the SARs and Phantom Stock will continue to be re-measured at each quarterly reporting date, the SARs and Phantom Stock are required to be accounted for prospectively at fair value using a fair value pricing model, such as Black-Scholes. The Company recorded the impact of the change in valuation methods as a cumulative effect of a change in accounting principle, as permitted by ASC 250. The effect of the change increased the SARs and Phantom Stock liability by $2.4 million which was the difference in compensation cost measured using the intrinsic value method and the fair value method. An equal and offsetting change to retained earnings in the condensed consolidated balance sheet was recorded with the revaluation. Any future changes in fair value will be recorded as compensation expense in the condensed consolidated statement of operations. |

| Recent Accounting Pronouncements |
In May 2014, the FASB issued ASU (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The standard establishes a new recognition model that requires revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. The Company may adopt the requirements of ASU 2014-09 using either of two acceptable methods: (1) retrospective adoption to each prior period presented with the option to elect certain practical expedients; or (2) adoption with the cumulative effect recognized at the date of initial application and providing certain disclosures. In July 2015, the FASB approved a one-year deferral of the effective date of the new standard, making it effective for our reporting periods beginning October 1, 2018. The Company has preliminarily elected to use the modified retrospective method to adopt the new guidance. The Company currently does not anticipate the adoption of ASU No. 2014 09 will have a material impact on its financial position and results of operations. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which provides guidance requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for substantially all leases, with the exception of short-term leases. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the statement of income. The guidance is effective for annual periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the potential impact of adopting this new guidance on its condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718)—Improvements to Employee Share-Based Payment Accounting, which simplifies several areas of accounting for share-based compensation arrangements, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 requires that the tax impact related to the difference between share-based compensation for book and tax purposes be recognized as income tax benefit or expense in the reporting period in which such awards vest.ASU 2016-09 also required a modified retrospective adoption for previously unrecognized excess tax benefits. The guidance in ASU 2016-09 is effective for public business entities for annual periods beginning after December 15, 2016, including interim periods within those annual reporting periods. The Company adopted ASU 2016-09 in the first quarter of fiscal 2018 on a modified retrospective basis, recognizing all excess tax benefits previously unrecognized, as a cumulative-effect adjustment increasing deferred tax assets by $0.4 million, increasing income tax expense by $0.3 million, and increasing retained earnings by $0.7 million. Adoption of ASU 2016-09 did not have any other material effect on the Company’s results of operations, financial position or cash flows. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force), which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of this standard on its condensed consolidated statements of cash flows. Further, in November 2016, the FASB issued ASU No. 2016-18 that requires restricted cash and cash equivalents to be included with cash and cash equivalents on the statement cash flows. The new standard is effective for fiscal years beginning after December 15, 2017, with early adoption permitted. The Company has restricted cash of $3.8 million as of June 30, 2018 and intends to adopt the new guidance in fiscal 2019. |

At June 30, 2018, the Company had capacity purchase agreements with American and United. All of the Company’s condensed consolidated revenue for the nine months ended June 30, 2018 and 2017 and accounts receivable at the end of each of these periods was derived from these agreements. The terms of both the American and United capacity purchase agreements are not aligned with the lease obligations on the aircraft performing services under such agreements. Amounts billed by the Company under capacity purchase agreements are subject to the Company’s interpretation of the applicable capacity purchase agreement and are subject to audit by the Company’s major airline partners. Periodically, the Company’s major airline partners dispute amounts billed and pay amounts less than the amount billed. Ultimate collection of the remaining amounts not only depends upon the Company prevailing under the applicable audit, but also upon the financial well-being of the major airline partner. As such, the Company periodically reviews amounts past due and records a reserve for amounts estimated to be uncollectible. The allowance for doubtful accounts was $1.7 million and $0.7 million at June 30, 2018 and September 30, 2017, respectively. If the Company’s ability to collect these receivables and the financial viability of our partners is materially different than estimated, the Company’s estimate of the allowance could be materially impacted. American accounted for approximately 54% and 55% of the Company’s total revenue for the three months ended June 30, 2018 and 2017, respectively, and 57% for the nine months ended June 30, 2018 and 2017, respectively. United accounted for approximately 46% and 45% of the Company’s revenue for the three months ended June 30, 2018 and 2017, respectively, and 43% for the nine months ended June 30, 2018 and 2017, respectively. A termination of either the American or the United capacity purchase agreement would have a material adverse effect on the Company’s business prospects, financial condition, results of operations, and cash flows. |

| Long-Term Debt and Other Borrowings |
Long-term debt as of June 30, 2018 and September 30, 2017, consisted of the following (in thousands):
Principal maturities of long-term debt as of June 30, 2018, and for each of the next five years are as follows (in thousands):
The net book value of collateralized aircraft and equipment as of June 30, 2018 was $1,170.4 million. In December 2015, an Enhanced Equipment Trust Certificate (“EETC”) pass-through trust was created to issue pass-through certificates to obtain financing for new E-175 aircraft. At June 30, 2018 Mesa has $217.9 million of equipment notes outstanding issued under the EETC financing included in long-term debt on the condensed consolidated balance sheets. The structure of the EETC financing consists of a pass-through trust created by Mesa to issue pass-through certificates, which represent fractional undivided interests in the pass-through trust and are not obligations of Mesa. The proceeds of the issuance of the pass-through certificates were used to purchase equipment notes which were issued by Mesa and secured by its aircraft. The payment obligations under the equipment notes are those of Mesa. Proceeds received from the sale of pass-through certificates were initially held by a depositary in escrow for the benefit of the certificate holders until Mesa issued equipment notes to the trust, which purchased such notes with a portion of the escrowed funds. Mesa evaluated whether the pass-through trust formed for its EETC financing is a Variable Interest Entity (“VIE”) and required to be consolidated. The pass-through trust was determined to be a VIE, however, the Company has determined that it does not have a variable interest in the pass-through trust, and therefore, has not consolidated the pass-through trust with its financial statements. On June 27, 2018, the Company refinanced $16.0 million of debt on six CRJ-900 aircraft (due in 2019), with $27.5 million of debt, resulting in net cash proceeds to the Company of $10.4 million after transaction related fees. The notes payable require quarterly payments of principal and interest through fiscal 2022 bearing interest at LIBOR plus 3.50%.
On June 28, 2018, the Company purchased nine CRJ-900 aircraft, which were previously leased under the GECAS Lease Facility, for $76.5 million. The Company financed the aircraft purchase with $69.6 million in new debt and proceeds from the June 2018 aircraft refinancing. The notes payable of $69.6 million require quarterly payments of principal and interest through fiscal 2022 bearing interest at LIBOR plus a spread ranging from 3.50% for the senior promissory notes to 7.50% for the subordinated promissory notes. The Company recorded non-cash lease termination expense of $15.1 million in connection with the lease buyout. Also, as part of the transaction, the Company (i) received $4.5 million of future goods and services credits and $5.6 million of loan forgiveness for loans with a maturity date in 2027 from the aircraft manufacturer, and (ii) mutually agreed with GE Capital Aviation Services LLC to terminate the GE Warrant. |

| Earnings Per Share and Equity |
Calculations of net income per common share attributable to Mesa Air Group were as follows (in thousands, except per share data):
Basic income per common share is computed by dividing net income attributable to Mesa Air Group by the weighted average number of common shares outstanding during the period. The number of incremental shares from the assumed issuance of shares relating to restricted stock and exercise of warrants is calculated by applying the treasury stock method. Share-based awards and warrants whose impact is considered to be anti-dilutive under the treasury stock method were excluded from the diluted net income or loss per share calculation. In loss periods, these incremental shares are excluded from the calculation of diluted loss per share, as the inclusion of unvested restricted stock and warrants would have an anti-dilutive effect. Anti-dilutive shares relating to restricted stock and exercise of warrants of 523,343 and 11,056,295, respectively, were excluded from the calculation of diluted loss per share for the three months ended June 30, 2018. |

The Company previously issued warrants to third parties, which had a five-year term to be converted to common stock at an exercise price of $0.004 per share. Outstanding warrants to purchase shares of common stock are held by persons who are not U.S. citizens. The warrants are not exercisable due to restrictions imposed by federal law requiring that no more than 24.9% of our stock be voted, directly or indirectly, or controlled by persons who are not U.S. citizens. The warrants can be converted to common stock upon warrant holders demonstrating U.S. citizenship. During June 2018, the Company extended the term of outstanding warrants set to expire by five years (through fiscal year 2023). Any warrants that were not extended were forfeited. On June 28, 2018, the Company agreed with GE Capital Aviation Services LLC (“GE Capital”) to terminate a warrant to purchase 250,000 shares of common stock held by GE Capital. Our shares of common stock are listed on the NASDAQ Global Market under the symbol “MESA” effective August 10, 2018. |

| Income Taxes |
The Company’s effective tax rate (ETR) from continuing operations was 23.9% and 228.2% for the three and nine months ended June 30, 2018 and 37.0% and 37.2% for the three and nine months ended June 30, 2017, respectively. The quarterly and year-to-dateETR was significantly different from our historical ETR as a result of the comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”) enacted by the U.S. government on December 22, 2017, the adoption of ASU 2016-09, state taxes, changes in the valuation allowance against state net operating losses, expired state attributes and the benefit from changes in state apportionment and statutory rates. The Tax Act makes broad and complex changes to the U.S. tax code that will affect the Company’s fiscal year ending September 30, 2018, including but not limited to (1) reducing the U.S. federal corporate tax rate, (2) changing rules related to uses and limitations of NOL carryforwards created in tax years beginning after December 31, 2017, (3) eliminating the corporate alternative minimum tax (“AMT”) and changing how existing AMT credits can be realized, and (4) bonus depreciation that will allow for full expensing of qualified property. The Tax Act reduces the federal corporate tax rate to 21% in the fiscal year ending September 30, 2018. The Internal Revenue Code stipulates that the Company’s fiscal year ending September 30, 2018, will have a blended corporate tax rate of 24.53%, which is based on the applicable tax rates before and after the Tax Act and the number of days in the year. The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. In connection with our initial analysis of the impact of the Tax Act, we have recorded a discrete net tax benefit of $21.4 million in the nine months ending June 30, 2018. As discussed more fully below, the Company has not completed its accounting for the income tax effects of certain elements of the Tax Act. The Company has recorded provisional adjustments where reasonable adjustments are available. Where reasonable adjustments are not available, the Company has not recorded and provisions adjustments and continues to account for them in accordance with ASC 740. Our accounting for the following elements of the Tax Act is complete: Reduction of U.S. federal corporate tax rate: The Act reduces the corporate tax rate to 21 percent, effective January 1, 2018. Consequently, we have recorded a decrease related to our net deferred tax liabilities of $21.4 million, with a corresponding net adjustment to deferred income tax benefit of $21.4 million for the nine months ended June 30, 2018. The Company was not able to make reasonable estimates or, correspondingly, record provisional adjustments for the following: Valuation allowances: The Company must determine whether the valuation allowance assessments are affected by various aspects of the Tax Act (e.g. section 163(j), state effect of The Act, net operating loss carryforwards). Any corresponding determinations relating to changes in valuation allowances have, likewise, not been completed or recorded. As of September 30, 2017, we had aggregate federal and state net operating loss carryforwards of approximately $299.8 million and $172.3 million, which expire in 2027-2036 and 2018-2037, respectively, with approximately $20.1 million of state net operating loss carryforwards expiring in 2018. The net operating loss carryforward increased by an estimated $111.4 million as of June 30, 2018 resulting in a total net operating loss carryforward of $411.2 million. |

Restricted Stock The restricted stock activity for the nine months ended June 30, 2018 were summarized as follows:
Stock Appreciation Rights The SARs activity for the nine months ended June 30, 2018 were summarized as follows:
Phantom Stock On October 17, 2017, the Company implemented a share-based payment plan under which employees, officers, directors and other individuals providing services to the Company are eligible to receive grants of restricted phantom stock units (“Phantom Stock Plan”). The restricted phantom stock units (“restricted stock units” or “RSUs”) provide a participant with the right to receive a cash or stock bonus based on the fair market value of a stated number of RSUs that are vested. The shares of Common Stock that may be subject to RSUs granted under the Plan shall not exceed an aggregate of 1,250,000 shares. All of the RSUs are non-vested and forfeitable as of the grant date and vest over a three-year period. Any vested RSU will be settled by the Company upon vesting but no later than March 15 of the calendar year after the date that the RSUs become vested. The Company has elected to use the fair value method to account for its share-based payment awards that are payable in cash, and therefore classified as liability awards, see Note 2: “Summary of Significant Accounting Policies” for effects due to a change in accounting method. Under the fair value method, the compensation expense associated with these awards is measured by estimated fair value of the Company’s common stock on the valuation date and is recognized ratably over the vesting period. Upon the settlement of a RSU, compensation cost is adjusted to the amount of the cash or stock payment. The Company estimates the fair value of its common stock based on recent share transactions. The Company has authorized 1,250,000 shares available under this plan and has granted 536,538 since inception of the plan. Since inception of the plan, 44,623 RSUs have vested or settled. The phantom stock activity for the nine months ended June 30, 2018 were summarized as follows:
As of June 30, 2018, there was $11.4 million, of total unrecognized compensation cost related to unvested share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of 1.6 years. Compensation cost for share-based awards are recognized on a straight-line basis over the vesting period. Share-based compensation expense for the three months ended June 30, 2018 and 2017 was $11.6 million and $0, respectively, and for the nine months ended June 30, 2018 and 2017 was $12.6 million and $1.7 million, respectively. Share-based compensation expenses are recorded in general and administrative expenses in the condensed consolidated statements of operations. Following the IPO there will be no further grants under the Stock Appreciation Rights and Phantom Stock plans. Immediately following the IPO, shares of restricted common stock were issued to certain of its employees and directors under its 2018 Plan in exchange for the cancellation of existing restricted phantom stock units, unvested restricted shares and SARs (see note 15—Subsequent Events). |

At June 30, 2018, the Company leased 28 aircraft under noncancelable operating leases with remaining terms of up to 5.75 years. The Company has the option to terminate certain leases at various times throughout the lease. The Company headquarters and other facility noncancelable operating leases have remaining terms of up to nine years. The leases require the Company to pay all taxes, maintenance, insurance, and other operating expenses. Rental expense is recognized on a straight-line basis over the lease term, net of lessor rebates and other incentives. Aggregate rental expense under all operating aircraft, equipment and facility leases totaled approximately $21.6 million and $21.0 million for the three months ended June 30, 2018 and 2017, respectively, and $62.8 million and $62.3 million for the nine months ended June 30, 2018 and 2017, respectively. Future minimum lease payments as of June 30, 2018, under noncancelable operating leases are as follows (in thousands):
The majority of the Company’s leased aircraft are leased through trusts that have a sole purpose to purchase, finance, and lease these aircraft to the Company; therefore, they meet the criteria of a variable interest entity. However, since these are single-owner trusts in which the Company does not participate, the Company is not at risk for losses and is not considered the primary beneficiary. Management believes that the Company’s maximum exposure under these leases is the remaining lease payments. |

Summary of Significant Accounting Policies (Policies) |
9 Months Ended |
|---|---|
Jun. 30, 2018 | |
| Basis of Presentation | Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its wholly owned operating subsidiaries. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). All intercompany accounts and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been derived from, and should be read in conjunction with, the Company’s audited consolidated financial statements and notes thereto as of and for the year ended September 30, 2017 included in the Company’s Registration Statement on Form S-1, FileNo. 333-226173 on file with the U.S. Securities and Exchange Commission (the “SEC”). There have not been any significant changes to the Company’s significant accounting policies during the nine months ended June 30, 2018, except for the valuation of stock compensation at fair value. Information and footnote disclosures normally included in financial statements have been condensed or omitted in these condensed consolidated financial statements pursuant to the rules and regulations of the SEC and GAAP. These condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the results of operations for the interim periods presented. The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and may remain an emerging growth company until the last day of the fiscal year following the fifth anniversary of the IPO, subject to specified conditions. The JOBS Act provides that an emerging growth company can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company has elected to “opt out” of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. |
| Use of Estimates | Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements. Actual results could differ from those estimates. |
| Rental Income | Rental Income The amount deemed to be rental income for the three months ended June 30, 2018 and 2017 was $53.5 million and $54.5 million, respectively, and for the nine months ended June 30, 2018 and 2017 was $162.0 million and $163.0 million, respectively. Rental income has been included in contract revenue on the Company’s condensed consolidated statements of operations. The Company has not separately stated aircraft rental income and aircraft rental expense in the condensed consolidated statements of operations since the use of the aircraft is not a separate activity of the total service provided. |
| Maintenance Expense | Maintenance Expense The Company operates under a Federal Aviation Administration (“FAA”) approved continuous inspection and maintenance program. The Company uses the direct expense method of accounting for its maintenance of regional jet engine overhauls, airframe, landing gear, and normal recurring maintenance wherein the expense is recognized when the maintenance work is completed, or over the period of repair, if materially different. For leased aircraft, the Company is subject to lease return provisions that require a minimum portion of the “life” of an overhaul be remaining on the engine at the lease return date. The Company estimates the cost of maintenance lease return obligations and accrues such costs over the remaining lease term when the expense is probable and can be reasonably estimated. Engine overhaul expense totaled $13.1 million and $8.4 million for the three months ended June 30, 2018 and 2017, respectively, of which $4.6 million and $0 was pass-through expense and $46.2 million and $53.5 million for the nine months ended June 30, 2018 and 2017, respectively, of which $9.8 million and $0 was pass-through expense. Airframe check expense totaled $6.3 million and $6.7 million for the three months ended June 30, 2018 and 2017, respectively, of which $1.6 million and $2.2 million was pass-through expense and $19.8 million and $16.9 million for the nine months ended June 30, 2018 and 2017, respectively, of which $7.3 million and $2.6 million was pass-through expense. Pursuant to the United capacity purchase agreement, United reimburses the Company for heavy maintenance on certain E-175 aircraft. Those reimbursements are included in pass-through and other revenue. See Note 1: “Organization and Operations” for further information. |
| Change in Accounting Policy | Change in Accounting Policy Stock Appreciation Rights (“SARs”) and Phantom Stock historically were accounted for as liability compensatory awards under ASC 710, Compensation – General, valued using the intrinsic value method, as permitted by ASC 718 for nonpublic entities. Upon becoming a public company, as defined in ASC 718, in the third quarter of 2018, the Company was required to change its methodology for valuing the SARs and Phantom Stock. While the SARs and Phantom Stock will continue to be re-measured at each quarterly reporting date, the SARs and Phantom Stock are required to be accounted for prospectively at fair value using a fair value pricing model, such as Black-Scholes. The Company recorded the impact of the change in valuation methods as a cumulative effect of a change in accounting principle, as permitted by ASC 250. The effect of the change increased the SARs and Phantom Stock liability by $2.4 million which was the difference in compensation cost measured using the intrinsic value method and the fair value method. An equal and offsetting change to retained earnings in the condensed consolidated balance sheet was recorded with the revaluation. Any future changes in fair value will be recorded as compensation expense in the condensed consolidated statement of operations. |
