| Summary of Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The consolidated financial statements of the Company are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP” ). The consolidated financial statements include the assets, liabilities and operating results of the Company. All intercompany balances and transactions have been eliminated in consolidation. Other than net loss, the Company does not have any other elements of comprehensive income or loss for the years ended December 31, 2023 and 2022. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of income and expense during the reporting period. On an ongoing basis, the Company evaluates its estimates using historical experience and other factors including the current economic and regulatory environment as well as management’s judgment. Items subject to such estimates and assumptions include: revenue recognition and related allowances, valuation allowance on deferred tax assets, certain accrued liabilities, useful lives and recoverability of long-lived assets, fair value of assets acquired and liabilities assumed in acquisitions, legal contingencies, assumptions underlying convertible notes and convertible securities carried at fair value and stock-based compensation. These estimates may change as new events occur and additional information is obtained and such changes are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates, and any such differences may be material to the Company’s consolidated financial statements. Concentration of Risk The financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and accounts receivable. All of the Company’s cash deposits are held at financial institutions that management believes to be of high credit quality. The Company’s cash deposit accounts may exceed federally insured limits at times. The Company has not experienced any losses on cash deposits to date. For the years ended December 31, 2023 and 2022, the US DOT accounted for 32 % and 0 %, respectively, of the Company's consolidated revenues. We are dependent on part suppliers to deliver necessary airplane components in a timely manner at prices and quality levels acceptable to us. Our inability to efficiently manage these suppliers could have a material adverse effect on our business, prospects, financial condition and operating results. Business Combination The Company is required to use the acquisition method of accounting for business combinations. The acquisition method of accounting requires the Company to allocate the purchase consideration to the assets acquired and liabilities assumed from the acquiree based on their respective fair values as of the Acquisition Date. The excess of the fair value of purchase consideration over the fair value of these assets acquired and liabilities assumed is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets. Critical estimates in valuing intangible assets include, but are not limited to, expected future cash flows, which includes consideration of future revenue growth and margins, and discount rates. Fair value estimates are based on the assumptions that management believes a market participant would use in pricing the asset or liability. These estimates are inherently uncertain and, therefore, actual results may differ from the estimates made. As a result, during the measurement period of up to one year from the Acquisition Date, the Company may record fair value adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired and liabilities assumed in an acquisition, whichever comes first, any subsequent adjustments are recorded in the Consolidated Statements of Operations. Cash and Restricted Cash Cash and restricted cash consists of cash on hand held in commercial bank accounts. The Company classifies all cash with use limited by contractual provisions as restricted cash. As of December 31, 2023 and 2022 the Company had restricted cash of $ 0.7 million and $ 0.9 million, resp ec tively, consisting of collateral against a corporate credit card. The Company has classified the restricted cash as long term, which represents the expected lapse of the restriction. Accounts Receivable, net Accounts receivable primarily consist of amounts due from U.S. DOT in relation to certain air routes served by the Company under the EAS program, amounts due from airline business partners, and pending transactions with credit card processors. Receivables from the U.S. DOT and our business partners are typically settled within 30 days. All accounts receivable are reported net of an allowance for credit losses, which was not material as of December 31, 2023 , and December 31, 2022. The Company has considered past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses. Collateralized Borrowings The Company has a revolving accounts receivable financing arrangement that allows the Company to borrow up to 90 % of eligible accounts receivable due from the U.S. DOT, in relation to certain air routes served by the Company under the EAS program, up to a maximum unsettled amount of $ 5 million. The financing arrangement is uncommitted, and upon funding does not qualify for sale accounting as the Company does not relinquish control of the receivables based on, among other things, the nature and extent of the Company’s continuing involvement. Accordingly, the accounts receivable remains on the Company’s balance sheet until paid by the customer and cash proceeds from the financing arrangement are recorded as collateralized borrowing in Accrued expenses and other current liabilities on the Consolidated Balance Sheets, with attributable interest expense recognized over the life of the related transactions. Interest expense and contractual fees associated with the collateralized borrowings are included in interest expense and other expense, net, respectively, in the accompanying Consolidated Statements of Operations. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Expenditures for major additions, equipment purchase deposits, renewals, and modifications are capitalized, while minor replacements, maintenance, and repairs, which do not extend the asset’s life, are expensed as incurred. The Company capitalizes expenditures for software developed or obtained for internal use. These costs include personnel and related employee benefits expenses for employees who are directly associated with and who devote time to software development projects, and external direct costs of consultants and materials for developing the software. Software development costs that do not qualify for capitalization as well as costs related to minor upgrades and enhancements are expensed as incurred and recorded in the Consolidated Statements of Operations. Maintenance and repairs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets, or, in the case of leasehold improvements, over the term of the lease or economic life, whichever is shorter as follows:
Assets Depreciable Life
Aircraft, equipment and rotable spares 3 to 20 years
Leasehold improvements Shorter of the estimated lease term or 5 years
Office, vehicles and ground equipment 3 years and 5 years
Internal-use software 3 years Depreciation of property and equipment is included within Depreciation and amortization on the Consolidated Statements of Operations. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any gain or loss is included in the Consolidated Statements of Operations. Intangible Assets Intangible assets consist primarily of EAS contracts, tradenames and trademarks and software acquired in an asset acquisition. The Company capitalizes expenditures for major software purchases. The Company amortizes finite-lived intangible assets on a straight-line basis over their estimated useful lives, which range from two to ten years . The straight-line recognition method approximates the manner in which the expected benefits will be derived. Impairment of Long-Lived Assets Long-lived assets such as property and equipment, finite-lived intangible assets, and right of use assets are reviewed for impairment, whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of the asset. The Company performs impairment testing at the asset group level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The amount of impairment loss, if any, is measured as the difference between the carrying value of the asset and its estimated fair value. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values, and third-party independent appraisals, as appropriate. No impairment charges were recorded during the years ended December 31, 2023 and 2022. Goodwill Goodwill, which represents the excess of the cost of an acquired entity over the fair value of the acquired net assets, has an indefinite life and, accordingly, is not amortized. The Company has two reporting units. The Company tests goodwill for impairment annually, during the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company assesses goodwill for impairment utilizing either a qualitative assessment or a quantitative assessment by comparing the fair value of its reporting unit with its carrying amount. If the Company decides that it is appropriate to perform a qualitative assessment and concludes that the fair value of its reporting unit more likely than not exceeds its carrying value, no further evaluation is necessary. If the Company performs the quantitative assessment, the Company will compare the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its fair value, the Company will recognize an impairment charge for the amount by which the carrying amount exceeds its reporting unit’s fair value. Shortly after the Southern Acquisition, the Company performed its annual goodwill impairment assessment on a qualitative basis as of October 1, 2023, and concluded that it was not more likely than not that the fair value of the reporting unit was less than its carrying value. This conclusion was primarily based on the operations of Southern being consistent with forecasts existing as of the acquisition date and the Company’s plans to re-fleet and expand Southern’s operations. Subsequent to this analysis, the Company identified indicators of impairment of the Southern reporting unit as of December 31, 2023. This was based on operational challenges that were expected to be remediated in the fourth quarter, such as: additional delays of aircraft maintenance due to the unavailability of parts, which resulted in a higher cancellation rate of scheduled flights. These delays are expected to continue into 2024. Additionally, the Company incurred higher cash requirements than expected to fund the operations of the Southern reporting unit during the fourth quarter of 2023, primarily due to higher maintenance costs. Further, unplanned delays in aircraft deliveries under the Textron aircraft supply agreement, including December 2023 cancellations of both firm deliveries and additional purchase options, have delayed re-fleeting efforts. Indicators of impairment also include a decline in the market price of our common stock and corresponding continued decline in our market capitalization from the date of the Southern Acquisition. As a result, we determined that it was more likely than not that the fair value of the Southern reporting unit was lower than its carrying value. As a result, the Company performed a quantitative assessment to compare the fair value of the reporting unit to its carrying amount as of December 31, 2023.The Company concluded that the carrying value of the Southern reporting unit exceeded its fair value and, as such, recorded a $ 60.0 million impairment of goodwill in its Southern reporting unit during the fourth quarter of 2023. The Company estimated the fair value of all reporting units utilizing both a market approach and an income approach (discounted cash flow) and the significant assumptions used to measure fair value include discount rate, terminal value factors, revenue and EBITDA multiples, and control premiums. We evaluate our estimates under the income approach by reconciling the estimated fair value of the reporting unit determined under the income approach to our market capitalization and estimated fair value determined under the market approach. This impairment charge is presented within impairment of goodwill on the Company’s Consolidated Statements of Operations. As of December 31, 2023 and 2022, the Company had no goodwill balance. Deferred Revenue The Company records deferred revenue (contract liabilities) when the Company receives customer payments in advance of the performance obligations being satisfied on the Company’s contracts. The Company generally collects payments from customers in advance of services being provided. The Company recognizes the deferred revenue as revenue when it meets the applicable revenue recognition criteria, which is usually either over the contract term, or when services have been provided. The Company generally meets performance obligations associated with all revenues deferred during the succeeding 12-month period. Accordingly, deferred revenue is classified within current liabilities and other long-term liabilities in the accompanying Consolidated Balance Sheets. Leases The Company leases aircraft, airport passenger terminal space, portions of and full aircraft hangars and other airport facilities, other commercial real estate and office space. Operating Leases Operating lease right-of-use assets and liabilities are recognized at the lease commencement date, which is the date the Company takes possession of the asset. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease right-of-use assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, the Company estimates incremental borrowing rates based on the appropriate term and information available at lease commencement in determining the present value of lease payments including reasonably certain renewal periods. The Company recognizes the lease cost for operating leases on a straight-line basis over the lease term. Aggregate lease cost is recorded in Cost of Revenue and General and Administrative expenses on the Consolidated Statements of Operations. Additionally, tenant incentives used to fund leasehold improvements or any rent abatements are recognized when earned and reduce the operating right-of-use asset related to the lease. Finance Leases The Company measures finance lease right-of-use assets and finance lease liabilities initially at an amount equal to the present value at the beginning of the lease term of minimum lease payments during the lease term, excluding that portion of the payments representing executory costs (such as insurance, maintenance, and taxes to be paid by the lessor) including any profit thereon, with the corresponding liability recorded within the liabilities section of the balance sheet. During the lease term, each minimum lease payment is allocated by the lessee between a reduction of the liability and interest expense to produce a constant periodic rate of interest on the remaining balance of the liability (the interest method). Finance lease right-of-use assets are depreciated in accordance with the Company’s property and equipment policy and is included within Depreciation and amortization on the Consolidated Statements of Operations. The corresponding lease liabilities are reduced as lease payments are made. Revenue Recognition Scheduled Revenue Scheduled revenue is derived from scheduled passenger flights under the EAS program, through membership subscriptions, principally relating to two main categories of membership: All-You-Can-Fly (“AYCF”) and Pay-As-You-Fly (“PAYF”), and through passenger single seat sales. The Company also provides scheduled passenger flight service on certain routes which is subsidized by the U.S. DOT under the EAS program. The EAS program is enacted to guarantee that small communities in the U.S. have the ability to maintain a minimum level of scheduled air services. These contracts are typically in duration of 2-4 years and include certain commitments for the Company to provide passenger air service to certain locations for a specific number of times annually to each location. The Company generally bills the U.S. DOT on the first of the month following the prior month’s completed flights, and typically collects from the U.S. DOT within 12 to 14 days after billing. Revenue is recognized when the flights are completed. AYCF memberships provide members the ability to take unlimited scheduled flights over the contract term, typically of one month. Customers benefit from the services evenly throughout the service period and the timing of when customers take flights under AYCF is not predictable. AYCF membership fees are billed to the member on a monthly basis in advance. The Company recognizes the AYCF membership revenue on a month-to-month basis. The Company has determined the AYCF membership represents a performance obligation. The Company also offers PAYF memberships to members. The members pay an annual membership fee, which enables the member to purchase single use vouchers for travel on the Company’s scheduled routes. Vouchers are sold in a package and generally expire twelve months after the purchase date. Vouchers are nonrefundable, not exchangeable for cash and may not be used for other Company services. The Company recognizes the upfront annual membership fee as well as amounts paid by members for the purchase of vouchers as flights are completed or expiration, where applicable, of the vouchers. The Company has determined the PAYF membership and vouchers to represent a single performance obligation. On-demand Revenue The Company earns revenue from the passenger for scheduled passenger flight service, as well as charter flights. These sales are generally paid for by credit card. The Company also earns revenue generated by third-party travel booking sites or travel agencies. Tickets are refundable within 24 hours of purchase for flights scheduled to take place more than one week out, or when flights or services are changed, interrupted, or otherwise canceled by the Company. The Company generally does not offer refunds after 24 hours of purchase. The Company recognizes revenue when it meets the applicable recognition criteria, which is at the point in time when a flight is completed or when tickets expire (generally within one year from the date of purchase). Other Revenue The Company also earns revenue from various ancillary services such as those relating to baggage fees, reservation change fees, package freight fees, and pet-travel (carry-on) fees. These fees are earned when the services are performed, generally at the time of travel. Principal vs Agent The Company evaluates whether it is a principal or an agent in contracts involving more than one party by assessing whether it controls the specified flight services before they are transferred to its customers. In transactions where the Company directs third-party air carriers to provide flights service to its customers, the Company determined it acts as the principal as it controls the services provided to the customers. In these instances, the Company is primarily responsible for fulfillment of the obligation in the contract, has pricing discretion, has the authority to direct the key components of the service on behalf of the member or customer regardless of which third-party is used. Therefore, the Company reports revenue and the associated costs on a gross basis in the Consolidated Statements of Operations. When the Company is not primarily responsible for the fulfillment of the flight services, it acts as an agent and therefore recognized revenue in the Consolidated Statements of Operations is net of amounts paid to third-party air carriers and operators that provide the services. In transactions where the Company operates aircraft on behalf of a third party, the Company determined it acts as the agent as it solely carries out the services based on the direction of the third party in exchange for a fixed service fee as determined by the related services agreement. In these instances, the Company reports the service fee as fee revenue net of any operating costs incurred by the Company to perform these services. Operating Expenses Cost of Revenue Cost of revenue consists of costs that are directly related to delivering the Company’s services and certain facility costs. Delivery of the Company’s services primarily comprise of aircraft maintenance, fuel, airport-related expenses, and fees paid to third-party air carriers for operating aircraft in providing flight services and platform infrastructure costs. Cost of revenue also includes facility costs representing leases expenses and operating costs for stations throughout the service network and personnel related costs, primarily salary and bonus. Cost of revenue excludes depreciation on property and equipment and amortization of finite-lived intangible assets. Sales and Marketing Sales and marketing expense consists primarily of personnel related and other costs in connection with the Company’s sales and marketing efforts. Advertising costs are expensed as incurred and were not material for the years ended December 31, 2023 and 2022, respectively. Sales and marketing excludes depreciation on property and equipment and amortization of finite-lived intangible assets. Technology and Development Technology and development expense consists of personnel and other costs related to technology development and management efforts including costs for third-party development resources, and allocations of overhead and facility costs. Technology cost also includes research and development cost associated with the Company’s hybrid electrification strategy. The Company’s technology and development efforts are focused on enhancing the ease of use and functionality of its existing software platform by adding new core functionality, services and other improvements, as well as the development of new products and services. Technology and development costs are expensed as incurred, except to the extent that such costs are associated with internal-use software development that qualify for capitalization, which are then recorded within Property and Equipment, net on the Company’s consolidated balance sheets. Technology and development excludes depreciation on property and equipment and amortization of finite-lived intangible assets. General and Administrative General and administrative expense consists of personnel related costs including salary, bonus, and share-based compensation for the Company’s executive, finance, facilities, and human resource teams and facility costs. General and administrative expenses also include professional fees and other corporate related expenses. General and administrative expenses exclude the depreciation on property and equipment and amortization of finite-lived intangible assets. Share-Based Compensation Options, RSPAs, and RSGAs The Company accounts for the issuance of ordinary share options, restricted share units (“RSUs”), restricted share purchase agreements (“RSPAs”), and restricted share grant agreements (“RSGAs”) in the consolidated financial statements based on the grant date fair value of the awards. Issuances of RSPAs with promissory notes are accounted for as share options and are measured based on the grant date fair value of the option. The Company estimates the fair value of the share options using the Black-Scholes option pricing model. The grant date fair value of share-based awards with service-only conditions is recognized as expense on a straight-line basis in the consolidated statement of operations over the requisite service period, which is generally the vesting period ranging from 12 to 48 months. Forfeitures are recorded as they occur. For awards with performance conditions, the Company records compensation expense on a graded-vesting basis when it is deemed probable that the performance condition will be met. For awards with market conditions, the effect of the market conditions is reflected in the fair value measurement and expense, using an option pricing model, recognized on a graded-vesting basis, is not reversed to the extent that the market condition is not achieved. Additionally, awards granted to non-employees are accounted for using their grant date fair value, using Black Scholes option pricing model and are accounted for in the same manner as awards granted to employees. Determining the fair value of share-based awards requires judgment. The Company’s use of option pricing models requires the input of subjective assumptions, including the fair value of shares of the Company’s Common Stock underlying the option award, the expected term of the option, the expected volatility of the Company’s Common Stock, risk-free interest rates, and the expected dividend yield of the Company’s Common Stock. The assumptions used in the Company’s option pricing model represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used the Company’s share-based compensation expense could be materially different in the future. Awards granted prior to the Company's direct listing were valued using the historical volatility of the stock price of similar publicly traded peer companies. The expected term of options granted represents the period for which the options are expected to be outstanding and is estimated based on a midpoint between the end of the requisite service period and the contractual term of the options granted. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect at the date of grant. The Company has no t declared or paid dividends to date and does not anticipate declaring dividends. As such, the dividend yield has been estimated to be zero . The Company’s assumptions may change for future grants. For awards granted prior to the Company’s direct listing, because there was no public market for the Company’s Common Stock, the board of directors determined the fair value of the shares of Common Stock by considering a number of objective and subjective factors including the results of third-party valuations, the Company’s actual operating and financial performance, market conditions and performance of comparable publicly traded companies, developments and milestones in the Company, the likelihood of achieving a liquidity event and transactions involving the Company’s preferred or common shares, among other factors. The fair value was determined in accordance with applicable elements of the practice aid issued by the American Institute of Certified Public Accountants, Valuation of Privately Held Company Equity Securities Issued as Compensation . Restricted Stock Unit Awards The grant date fair value of RSUs is estimated based on the fair value of the Company’s Common Stock on the date of grant. Prior to the Company’s direct listing in July 2023, RSUs granted by the Company vested upon the satisfaction of both service-based vesting conditions and liquidity event-related performance vesting conditions. The liquidity event-related performance vesting conditions were achieved upon the consummation of the Company's direct listing. Stock-based compensation related to such awards was recorded in full, as of the date of the Company’s direct listing. Since the Company’s direct listing in July 2023, the Company has only granted RSUs that vest upon the satisfaction of a service-based vesting condition and the compensation expense for these RSUs is recognized on a straight-line basis from the date of grant over the requisite service period. The Company has granted founder performance-based restricted stock units (“founder PRSUs”) that contain a market condition in the form of future stock price targets. The grant date fair value of the founder PRSUs was determined using a Monte Carlo simulation model and the Company estimates the derived service period of the founder PRSUs. The grant date fair value of founder PRSUs containing a market condition is recorded as stock-based compensation over the derived service period. Provided that each founder continues to be employed by the Company, stock-based compensation expense is recognized over the derived service period, regardless of whether the stock price goals are achieved. If the stock price goals are met sooner than the derived service period, any unrecognized compensation expenses related to the founder PRSUs will be expensed during the period in which the stock price targets are achieved. Warrants The Company assesses whether warrants issued to purchase the Company’s Common Stock are liability or equity-classified based on the terms of the warrants. If the warrants are determined to be liability-classified, then the warrants are remeasured to fair value each period with changes in fair value recorded within Changes in fair value of financial instruments carried at fair value, net on the Consolidated Statements of Operations. The Company recognizes the fair value of liability-classified warrants within Other liabilities in its Consolidated Balance Sheets. If the warrants are determined to be equity-classified, then the initial fair value is recorded in Additional paid-in capital and the warrants are not remeasured thereafter. The Company estimates the fair value of warrants to purchase its Common Stock and redeemable convertible preferred shares using the Black-Scholes option pricing model. Warrants are principally issued to lenders and non-employees, some of whom are related parties, in connection with debt and equity fundraising and debt restructuring activities. Income Taxes Income taxes are accounted for under the asset and liability method in accordance with U.S. GAAP. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statements carrying amounts of existing assets and liabilities and their respective tax bases and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The likelihood of realizing the tax benefits related to a potential deferred tax asset is evaluated, and a valuation allowance is recognized to reduce that deferred tax asset if it is mo |
