1. Summary of Significant Accounting Policies
Basis of Presentation
The condensed consolidated financial statements have been prepared in accordance with the generally accepted accounting principles in the United States (“GAAP”) and include the accounts of Frontier Group Holdings, Inc. (“FGHI” or the “Company”) and its wholly-owned direct and indirect subsidiaries, including Frontier Airlines Holdings, Inc. (“FAH”) and Frontier Airlines, Inc. (“Frontier”). All wholly-owned subsidiaries are consolidated, with all intercompany transactions and balances being eliminated.
The Company is an ultra low-cost, low-fare airline headquartered in Denver, Colorado that offers flights throughout the United States and to select international destinations in the Americas, serving approximately 100 airports.
The Company is managed as a single business unit that provides air transportation for passengers. Management has concluded there is only one reportable segment.
The accompanying condensed consolidated financial statements include the accounts of the Company and reflect all normal recurring adjustments which management believes are necessary to fairly present the financial position, results of operations and cash flows of the Company for the respective periods presented. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for Form 10-Q. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, which was filed with the SEC on February 20, 2024 (the “2023 Annual Report”).
The interim results reflected in the unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for other interim periods or for the full year. The air transportation business is subject to significant seasonal fluctuations and is volatile and highly affected by economic cycles and trends.
Reclassifications
A reclassification of previously reported amounts has been made to conform to the current year’s presentation in the Company’s condensed consolidated statements of operations. The reclassification relates to the removal of transaction and merger-related costs and the reclassification of these costs into other operating expenses. This reclassification did not impact previously reported amounts on the Company’s condensed consolidated balance sheets, condensed consolidated statements of comprehensive income (loss), condensed consolidated statements of cash flows or condensed consolidated statements of stockholders’ equity.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates.

2. Revenue Recognition
As of June 30, 2024 and December 31, 2023, the Company’s air traffic liability balance was $325 million and $259 million, respectively, which includes amounts classified within other long-term liabilities on the Company’s condensed consolidated balance sheets. During the six months ended June 30, 2024, 89% of the air traffic liability as of December 31, 2023 was recognized as passenger revenue within the Company’s condensed consolidated statements of operations. Of the air traffic liability balances as of June 30, 2024 and December 31, 2023, $47 million and $60 million, respectively, was related to unearned membership fees.
During the three and six months ended June 30, 2024 and 2023, the Company recognized $10 million, $18 million, $10 million and $20 million, respectively, of revenue related to expected and actual expiration of customer rights to book future travel in passenger revenues within the Company’s condensed consolidated statements of operations.
Operating revenues are comprised of passenger revenues, which includes fare and non-fare passenger revenues, and other revenues. Disaggregated operating revenues are as follows (in millions):

The Company is managed as a single business unit that provides air transportation for passengers. Operating revenues by principal geographic region, as defined by the U.S. Department of Transportation (the “DOT”), are as follows (in millions):
Three Months Ended June 30,Six Months Ended June 30,
2024202320242023
Domestic$904 $877 $1,706 $1,658 
Latin America69 90 132 157 
Total operating revenues$973 $967 $1,838 $1,815 
The Company attributes operating revenues by geographic region based upon the origin and destination of each passenger flight segment. The Company’s tangible assets consist primarily of flight equipment, which are mobile across geographic markets. Accordingly, assets are not allocated to specific geographic regions.
Frequent Flyer Program
The Company’s FRONTIER Miles program provides frequent flyer travel awards to program members based on accumulated miles. Miles are generally accumulated as a result of travel, purchases using the co-branded credit card and purchases from other participating partners. The Company defers revenue for miles earned by passengers under
See Notes to Condensed Consolidated Financial Statements

FRONTIER GROUP HOLDINGS, INC.
Notes to Condensed Consolidated Financial Statements (Continued)
(unaudited)

its FRONTIER Miles program based on the equivalent ticket value a passenger receives by redeeming miles for a ticket rather than paying cash.
The Company has a credit card affinity agreement with its credit card partner, Barclays Bank Delaware (“Barclays”), through 2029, which provides for joint marketing, grants certain benefits to co-branded credit cardholders (“Cardholders”) and allows Barclays to market using the Company’s customer database. Cardholders earn miles under the FRONTIER Miles program and the Company sells miles at agreed-upon rates to Barclays and earns fees from Barclays for the acquisition, retention and use of the co-branded credit card by consumers.

4. Financial Derivative Instruments and Risk Management
The Company may be exposed to interest rate risk through aircraft and spare engine lease contracts for the time period between agreement of terms and commencement of the lease, when portions of rental payments can be adjusted and become fixed based on the swap rate. As part of its risk management program, from time to time the Company enters into contracts in order to limit the exposure to fluctuations in interest rates. During each of the three and six months ended June 30, 2024 and 2023, the Company did not enter into any swaps and, therefore, paid no upfront premiums for options. As of June 30, 2024, the Company had no interest rate hedges outstanding.
Assets associated with the Company’s derivative instruments are presented on a gross basis and include upfront premiums paid. These assets are recorded as a component of other current assets on the Company’s condensed consolidated balance sheets. There were no assets outstanding as of June 30, 2024 and December 31, 2023, respectively.
The following table summarizes the effect of interest rate derivative instruments reflected in rent expense within the Company’s condensed consolidated statements of operations (in millions):

__________________
(a)The Company, through an affiliate, entered into the pre-delivery deposit payment (“PDP”) facility with Citibank, N.A., as facility agent, in December 2014 (as amended from time to time, the “PDP Financing Facility”). The PDP Financing Facility is collateralized by the Company’s purchase agreement for Airbus A320neo family aircraft deliveries (see Note 9) through the term of the facility, which extends through December 2026. The total available capacity of the PDP Financing Facility is $365 million.
See Notes to Condensed Consolidated Financial Statements

FRONTIER GROUP HOLDINGS, INC.
Notes to Condensed Consolidated Financial Statements (Continued)
(unaudited)

Interest is paid every 90 days based on the Secured Overnight Financing Rate (“SOFR”) plus a margin for each individual tranche. The PDP Financing Facility consists of separate loans for each PDP aircraft. Each separate loan matures upon the earlier of (i) delivery of that aircraft to the Company by Airbus, (ii) the date one month following the last day of the scheduled delivery month of such aircraft and (iii) if there is a delay in delivery of aircraft, depending on the cause of the delivery delay, up to six months following the last day of the scheduled delivery month of such aircraft. The PDP Financing Facility will be repaid periodically according to the preceding sentence, with the PDP Financing Facility maturing in December 2026.
(b)Represents a note with a commercial bank related to the Company’s headquarters. In June 2024, the Company’s previous note related to its headquarters reached maturity and a final payment of $16 million was made to cover all unpaid principal, accrued unpaid interest and other amounts due. Subsequent to this final payment, the Company entered into a new $6 million note with a different commercial bank maturing in June 2031. Under the terms of the new outstanding note, the Company is required to make regular monthly payments on principal and unpaid interest. On the maturity date, one final balloon payment will be made to cover all unpaid principal, accrued unpaid interest and other amounts due. Interest on the new note will accrue on the unpaid principal balance at a fixed annual rate of 6.79%.
(c)The Company entered into an agreement with Barclays in 2003 which, as amended, provides for joint marketing, grants certain benefits to Cardholders and allows Barclays to market using the Company’s customer database, through 2029. Cardholders earn miles under the FRONTIER Miles program and the Company sells miles at agreed-upon rates to Barclays and earns fees from Barclays for the acquisition, retention and use of the co-branded credit card by Cardholders. In addition, Barclays will pre-purchase miles if the Company so requests and meets certain conditions precedent. The pre-purchased miles facility amount available to the Company is to be reset on January 15 of each calendar year through, and including, January 15, 2028, based on the aggregate amount of fees payable by Barclays to the Company on a calendar year basis and subject to certain other conditions, up to an aggregate maximum facility amount of $200 million. The Company pays interest on a monthly basis, which is based on a one-month Effective Federal Funds Rate (“EFFR”) plus a margin. Beginning March 2028, the facility is scheduled to be repaid in 12 equal monthly installments.
(d)As a result of the Company’s participation in the payroll support programs offered by the U.S. Department of the Treasury (the “Treasury”), the Company obtained a series of 10-year, low-interest loans from the Treasury (collectively, the “PSP Promissory Notes”) that are due between 2030 and 2031. The PSP Promissory Notes include an annual interest rate of 1.00% for the first five years and the SOFR plus 2.00% in the final five years, with bi-annual interest payments. The loans can be prepaid at par at any time without incurring a penalty.
In connection with the term loan facility entered into with the Treasury on September 28, 2020, which was repaid in full on February 2, 2022, and the PSP Promissory Notes, the Company issued warrants to purchase 3,117,940 shares of FGHI common stock at a weighted-average price of $6.95 per share. These warrants will expire between May 2025 and June 2026. No warrants have been exercised as of June 30, 2024.
Cash payments for interest related to debt were $17 million and $12 million for the six months ended June 30, 2024 and 2023, respectively.
The Company has caused standby letters of credit and surety bonds to be issued to various airport authorities and vendors that are collateralized by a portion of the Company’s property and equipment and, as of June 30, 2024 and December 31, 2023, the Company did not have any outstanding letters of credit that were drawn upon.
As of June 30, 2024, future maturities of debt are payable as follows (in millions):

7. Operating Leases
Aircraft
As of June 30, 2024, the Company leased 148 aircraft with remaining terms ranging from 8 months to 12 years, all of which are under operating leases and are included within operating lease right-of-use assets and operating lease liabilities on the Company’s condensed consolidated balance sheets. In addition, as of June 30, 2024, the Company leased 33 spare engines which are all under operating leases, with the remaining term ranging from one month to 12 years. As of June 30, 2024, the lease rates for 10 of the engines depend on usage-based metrics which are variable and, as such, these leases are not recorded on the Company’s condensed consolidated balance sheets as operating lease right-of-use assets or as operating lease liabilities.
During the three and six months ended June 30, 2024 and 2023, the Company executed sale-leaseback transactions with third-party lessors for six, twelve, one and four new Airbus A320neo family aircraft, respectively. The Company did not enter into any direct leases during the three and six months ended June 30, 2024 and entered into two and five direct leases for new Airbus A320neo family aircraft during the three and six months ended June 30, 2023, respectively. Additionally, the Company completed sale-leaseback transactions for two, two, one and two engines during the three and six months ended June 30, 2024 and 2023, respectively. All of the leases from the sale-leaseback transactions are accounted for as operating leases. The Company recognized sale-leaseback gain transactions of $77 million, $148 million, $17 million and $57 million during the three and six months ended June 30, 2024 and 2023, respectively, which are included as a component of other operating expenses within the Company’s condensed consolidated statements of operations.
Aircraft Rent Expense and Maintenance Obligations
During the three and six months ended June 30, 2024 and 2023, aircraft rent expense was $147 million, $306 million, $148 million and $279 million, respectively. Aircraft rent expense includes supplemental rent, which is made up of maintenance-related reserves and probable lease return condition obligations. Supplemental rent expense (benefit) for maintenance-related reserves was $(7) million for each of the three and six months ended June 30, 2024, and $(2) million for each of the three and six months ended June 30, 2023. The portion of supplemental rent expense related to probable lease return condition obligations was $1 million, $14 million, $22 million and $24 million for the three and six months ended June 30, 2024 and 2023, respectively. As of June 30, 2024 and December 31, 2023, the Company’s total leased aircraft return cost liability was $31 million and $26 million, respectively, which are reflected in other current liabilities and other long-term liabilities within the Company’s condensed consolidated balance sheets.
During the three months ended June 30, 2024, the Company reached an agreement with one of its aircraft lessors which eliminated requirements to pay maintenance reserves held as collateral in advance of the Company’s required performance of major maintenance activities on its aircraft leases. As a result of the agreement, the lessor disbursed back to the Company previously paid aircraft maintenance deposits of approximately $104 million, resulting in the Company no longer having any aircraft maintenance deposits with any of its lessors as of June 30, 2024.
During the three months ended June 30, 2024, the Company extended the term for certain aircraft operating leases that were slated to expire between 2025 and 2027. For the three and six months ended June 30, 2024, the Company recorded a benefit of $11 million and $14 million, respectively, to aircraft rent in the Company’s condensed consolidated statements of operations related to previously accrued lease return costs that were variable in nature and associated with the anticipated utilization and condition of the airframes and engines at the original return date. Given the extension of these aircraft operating leases, such variable return costs are no longer probable of occurring.

During the six months ended June 30, 2023, the Company extended the term for certain aircraft operating leases that were slated to expire in the fourth quarter of 2023. For the six months ended June 30, 2023, the Company recorded an $18 million benefit to aircraft rent in the Company’s condensed consolidated statement of operations related to previously accrued lease return costs that were variable in nature and associated with the anticipated utilization and condition of the airframes and engines at the original return date. Given the extension of these aircraft operating leases, such variable return costs are no longer probable of occurring.
Airport Facilities
The Company’s facility leases are primarily for space at approximately 100 airports, primarily in the United States. These leases are classified as operating leases and reflect the use of airport terminals, ticket counters, office space and maintenance facilities. Generally, this space is leased from government agencies that control the use of the airport. The majority of these leases are short-term in nature and renew on an evergreen basis. For these leases, the contractual term is used as the lease term. As of June 30, 2024, the remaining lease terms vary from one month to 10 years. At the majority of the U.S. airports, the lease rates depend on airport operating costs or use of the facilities and are reset at least annually, and because of the variable nature of the rates, these leases are not recorded on the Company’s condensed consolidated balance sheets as right-of-use assets and lease liabilities.
Other Ground Property and Equipment
The Company leases certain other assets such as flight training equipment, building space, and various other equipment. Certain of the Company’s leases for other assets are deemed to contain fixed rental payments and, as such, are classified as operating leases and are recorded on the Company’s condensed consolidated balance sheets as a right-of-use asset and liability. The remaining lease terms ranged from one month to eight years as of June 30, 2024.
Lease Costs
The table below presents certain information related to lease costs for operating leases during the three and six months ended June 30, 2024 and 2023 (in millions):

8. Stock-Based Compensation
During the three and six months ended June 30, 2024 and 2023, the Company recognized $5 million, $9 million, $3 million and $7 million, respectively, in stock-based compensation expense, which is included as a component of salaries, wages and benefits within the Company’s condensed consolidated statements of operations.
Stock Options and Restricted Stock Units
During the six months ended June 30, 2024, no stock options were granted and 758,217 vested stock options were exercised with a weighted-average exercise price of $1.25 per share. As of June 30, 2024, the weighted-average exercise price of outstanding stock options was $5.26 per share.
During the six months ended June 30, 2024, 1,409,000 restricted stock units were issued with a weighted-average grant date fair value of $5.53 per share. During the six months ended June 30, 2024, 990,525 restricted stock units vested, of which 275,866 restricted stock units were withheld to cover employees’ tax withholding obligations, with a weighted-average grant date fair value of $11.79 and $12.68 per share, respectively.
Stockholders’ Equity
As of June 30, 2024 and December 31, 2023, the Company had authorized common stock (voting), common stock (non-voting) and preferred stock of 750,000,000, 150,000,000 and 10,000,000 shares, respectively, of which only common stock (voting) were issued and outstanding. All classes of equity have a par value of $0.001 per share.

(a)    While the schedule presented reflects the contractual delivery dates as of June 30, 2024, the Company has recently experienced delays in the deliveries of Airbus aircraft which may persist in future periods.
The Company is party to certain aircraft purchase agreements with Airbus (as amended from time to time, the “Airbus Purchase Agreements”) pursuant to which, as of June 30, 2024, the Company had commitments to purchase an aggregate of 49 A320neo and 149 A321neo aircraft, with deliveries expected through 2029 per the latest delivery schedule. In June 2024, the Company provided notice to Airbus as permitted in the Airbus Purchase Agreements that it will not purchase any A321XLR aircraft and will convert 18 A320neo to A321neo aircraft. This conversion has been reflected in the table above.
The Airbus Purchase Agreements also provide for, among other things, varying purchase incentives for each aircraft type (e.g., A320neo versus A321neo), which are allocated proportionally by aircraft type over the remaining

(unaudited)

aircraft to be delivered so that each aircraft’s capitalized cost upon induction would be equal. Therefore, as cash paid for deliveries is greater than the capitalized cost due to the allocation of these purchase incentives, a deferred purchase incentive is recognized, which will ultimately be offset by future deliveries of aircraft with lower cash payments than their associated capitalized cost. As of June 30, 2024 and December 31, 2023, the Company had $88 million and $78 million, respectively, of deferred purchase incentives recognized within other assets on the Company’s condensed consolidated balance sheets.
As of June 30, 2024, purchase commitments for these aircraft and engines, including estimated amounts for contractual price escalations and PDPs, consisted of the following (in millions):

Litigation and Other Contingencies
The Company is subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. During 2023, the DOT sent the Company a request for information to assist in its investigation into whether the Company cared for its customers as required by law during Winter Storm Elliott, which caused significant operational disruptions and spanned from December 21, 2022 to January 2, 2023, including providing adequate customer service assistance, prompt flight status notifications, and proper and timely refunds. The Company is fully cooperating with the DOT request.
The Company regularly evaluates the status of such matters to assess whether a loss is probable and reasonably estimable in determining whether an accrual is appropriate. Furthermore, in determining whether disclosure is appropriate, the Company evaluates each matter to assess if there is at least a reasonable possibility that a loss or additional losses may have been incurred and whether an estimate of possible loss or range of loss can be made.
The ultimate outcome of legal actions is unpredictable and can be subject to significant uncertainties, and it is difficult to determine whether any loss is probable or even possible. Additionally, it is also difficult to estimate the amount of loss and there may be matters for which a loss is probable or reasonably possible but not currently estimable. Thus, actual losses may be in excess of any recorded liability or the range of reasonably possible loss. The Company believes the ultimate outcome of any potential lawsuits, proceedings and reviews will likely not, individually or in the aggregate, have a material adverse effect on its condensed consolidated financial position, liquidity or results of operations and that the Company’s current accruals cover matters where loss is deemed probable and can be reasonably estimated.
In situations where the Company may be a plaintiff and receives, or expects to receive, a favorable ruling related to litigation, the Company follows the accounting standards codification guidance for gain contingencies. The Company does not recognize a gain contingency within its condensed consolidated financial statements prior to the settlement of the underlying events or contingencies associated with the gain contingency. As a result, the consideration related to a gain contingency is recorded in the condensed consolidated financial statements during the period in which all underlying events or contingencies are resolved and the gain is realized. During the three months ended June 30, 2024, the Company received a favorable ruling in the U.S District Court for the Southern District of New York regarding a breach of contract action against a former aircraft lessor in which the Company was awarded

$50 million in damages plus post-judgement interest. Given that the judgment has been appealed to the Unites States Court of Appeals for the Second Circuit, the Company has not recorded any amounts within the condensed consolidated financial statements as of June 30, 2024.
Employees
The Company has seven union-represented employee groups that together represented approximately 88% of all employees as of June 30, 2024. The table below sets forth the Company’s employee groups and status of the collective bargaining agreements as of June 30, 2024:

(d)    The Company’s collective bargaining agreements with its aircraft appearance agents, material specialists, and maintenance controllers, each represented by IBT, were still amendable as of June 30, 2024, and pursuant to the Railway Labor Act the parties continue to be bound by the existing agreements as negotiations continue.
The Company is self-insured for health care claims, subject to a stop-loss policy, for eligible participating employees and qualified dependent medical and dental claims, subject to deductibles and limitations. The Company’s liabilities for claims incurred but not reported are determined based on an estimate of the ultimate aggregate liability for claims incurred. The estimate is calculated from actual claim rates and adjusted periodically as necessary. The Company had accrued $6 million and $5 million for health care claims estimated to be incurred but not yet paid, as of June 30, 2024 and December 31, 2023, respectively, which are included as a component of other current liabilities on the Company’s condensed consolidated balance sheets.
General Indemnifications
The Company has various leases with respect to real property as well as various agreements among airlines relating to fuel consortia or fuel farms at airports. Under some of these contracts, the Company is party to joint and several liability regarding environmental damages. Under others, where the Company is a member of an LLC or other entity that contracts directly with the airport operator, liabilities are borne through the fuel consortia structure.
The Company’s aircraft, services, equipment lease and sale and financing agreements typically contain provisions requiring the Company, as the lessee, obligor or recipient of services, to indemnify the other parties to those agreements, including certain of those parties’ related persons, against virtually any liabilities that might arise from the use or operation of the aircraft or such other equipment. The Company believes that its insurance would cover most of its exposure to liabilities and related indemnities associated with the commercial real estate leases and aircraft, services, equipment lease and sale and financing agreements described above.
See Notes to Condensed Consolidated Financial Statements

FRONTIER GROUP HOLDINGS, INC.
Notes to Condensed Consolidated Financial Statements (Continued)
(unaudited)

Certain of the Company’s aircraft and other financing transactions include provisions that require payments to preserve an expected economic return to the lenders if that economic return is diminished due to certain changes in law or regulations. In certain of these financing transactions and other agreements, the Company also bears the risk of certain changes in tax laws that would subject payments to non-U.S. entities to withholding taxes.
Certain of these indemnities survive the length of the related financing or lease. The Company cannot reasonably estimate the potential future payments under the indemnities and related provisions described above because it cannot predict (i) when and under what circumstances these provisions may be triggered, and (ii) the amount that would be payable if the provisions were triggered because the amounts would be based on facts and circumstances existing at such time.
10. Earnings (Loss) per Share
Basic and diluted earnings (loss) per share are computed pursuant to the two-class method. Under the two-class method, the Company attributes net income to common stock and other participating rights (including those with vested share-based awards). Basic earnings per share is calculated by taking net income, less earnings allocated to participating rights, divided by the basic weighted-average common stock outstanding. In accordance with the two-class method, diluted earnings per share is calculated using the more dilutive impact of the treasury-stock method or from reducing net income for the earnings allocated to participating rights.
The following table sets forth the computation of earnings (loss) per share on a basic and diluted basis pursuant to the two-class method for the periods indicated (in millions, except for share and per share data):

Approximately 5,007,745 and 5,154,621 shares were excluded from the computation of diluted weighted-average shares for the three and six months ended June 30, 2024, respectively, due to anti-dilutive effects. Approximately 2,886,151 and 2,264,024 shares were excluded from the computation of diluted weighted-average shares for the three and six months ended 2023, respectively, due to anti-dilutive effects.

11. Income Taxes
The Company’s provision for income taxes during interim reporting periods has historically been calculated by applying an estimate of the annual effective tax rate for the full fiscal year to pretax income (loss) excluding unusual or infrequently occurring discrete items for the reporting period. When a reliable estimate cannot be made, the Company computes the interim provision based on the actual effective tax rate for the year-to-date period by applying the discrete method. The Company determined that given small changes in estimated ordinary income would result in significant variation in the estimated annual effective tax rate for the current year and the resulting uncertainty of the impact on the valuation allowance, the discrete method represents the best estimate of the actual effective tax rate and the Company has calculated its effective tax using the discrete method for the three and six months ended June 30, 2024. The Company’s effective tax rate for the three and six months ended June 30, 2024 was an expense of 3.1% and 37.5%, respectively, on pre-tax income, compared to an expense of 19.3% and 18.3%, respectively, on pre-tax income for the three and six months ended June 30, 2023. The effective tax rate for the three months ended June 30, 2024 was lower than the statutory rate primarily related to a decrease in the Company’s valuation allowance relating to U.S. federal and state net operating losses. The effective tax rate for the six months ended June 30, 2024 was higher than the statutory rate primarily due to the non-deductibility of certain executive compensation costs and other employee benefits, as well as shortfalls related to the vesting and exercise of the Company’s share-based awards offset by a decrease in the valuation allowance. The Company’s effective tax rate for the three and six months ended June 30, 2023 was lower than the statutory rate primarily due to excess tax benefits associated with the Company’s stock-based compensation arrangements.
The Company accounts for income taxes using the asset and liability method. Deferred income taxes are recognized for the tax consequences of temporary differences between the tax and financial statement reporting bases of assets and liabilities. Quarterly, the Company assesses whether it is more likely than not that sufficient taxable income will be generated to realize deferred income tax assets, and a valuation allowance is recorded when it is more likely than not that some portion, or all, of the Company’s deferred tax assets, will not be realized. The Company considers sources of taxable income from prior period carryback periods, future reversals of existing taxable temporary differences, tax planning strategies and future projected taxable income when assessing the future realization of deferred tax assets.
In assessing the sources of taxable income and the need for a valuation allowance, the Company considers all available positive and negative evidence, which includes a recent history of cumulative losses. As of June 30, 2024, the Company remains in a historical three-year cumulative loss position, which is significant objective negative evidence in considering whether deferred tax assets are realizable. Such objective negative evidence outweighs other subjective positive evidence, such as the projection of future taxable income. As a result, as of June 30, 2024, the Company has a valuation allowance of $35 million against its deferred tax assets for U.S. federal and state net operating loss carryforwards, which includes reductions in the Company’s valuation allowance of $7 million and $2 million, respectively, recorded during the three and six months ended June 30, 2024.
12. Fair Value Measurements
Under ASC 820, Fair Value Measurements and Disclosures, disclosures relating to how fair value is determined for assets and liabilities are required, and a hierarchy for which these assets and liabilities must be grouped is established, based on significant levels of inputs, as follows:
Level 1—Quoted prices in active markets for identical assets or liabilities.
Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
See Notes to Condensed Consolidated Financial Statements

FRONTIER GROUP HOLDINGS, INC.
Notes to Condensed Consolidated Financial Statements (Continued)
(unaudited)

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes several valuation techniques in order to assess the fair value of its financial assets and liabilities.
Cash, Cash Equivalents and Restricted Cash
Cash, cash equivalents and restricted cash are comprised of liquid money market funds, time deposits and cash, and are categorized as Level 1 instruments. The Company maintains cash with various high-quality financial institutions and holds restricted cash to secure medical claims paid. Cash, cash equivalents and restricted cash are carried at cost, which management believes approximates fair value. As of June 30, 2024 and December 31, 2023, the Company had less than $1 million of restricted cash.
Debt
The estimated fair value of the Company’s debt agreements has been determined to be Level 3 measurement, as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes a discounted cash flow method to estimate the fair value of the Level 3 debt.
The carrying amounts and estimated fair values of the Company’s debt are as follows (in millions):

Management Services
Indigo Partners LLC (“Indigo Partners”) managed an investment fund, Indigo Frontier Holdings Company, LLC (“Indigo Frontier”), that was the controlling stockholder of the Company until April 2024, when Indigo Frontier distributed all of its shares held to its members on a pro rata basis, in-kind and without consideration. Certain affiliates of Indigo Partners continue to be substantial stockholders of the Company. Indigo Partners continues to provide management services to the Company, for which the Company is assessed a quarterly fee. The Company recorded $1 million for each of the three and six months ended June 30, 2024 and 2023 for these fees, which are included as other operating expenses within the Company’s condensed consolidated statements of operations.
Codeshare Arrangement
The Company entered into a codeshare agreement with Controladora Vuela Compañía de Aviación, S.A.B. de C.V. (an airline based in Mexico doing business as “Volaris”) during 2018. Two of the Company’s directors are members of the board of directors of Volaris and one is an honorary director.
In August 2018, the Company and Volaris began operating scheduled codeshare flights. Each party bears its own costs and expenses of performance under the codeshare agreement. The codeshare agreement is subject to automatic renewals and may be terminated by either party at any time upon the satisfaction of certain conditions.
14. Subsequent Events
Flight Equipment Commitments
In August 2024, the Company and Airbus entered into a binding term sheet, subject to execution of customary closing documentation, to, among other things, update the remaining firm aircraft purchase order delivery schedule, which defers previously scheduled firm aircraft delivery dates from 2025 through 2028 to later years.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
General
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q, as well as Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Part II, Item 8. “Financial Statements and Supplementary Data” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, which was filed with the SEC on February 20, 2024 (the “2023 Annual Report”). This discussion contains forward-looking statements based upon current plans, expectations and beliefs involving risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth in the “Risk Factors” section of our 2023 Annual Report and other factors set forth in other parts of this Quarterly Report on Form 10-Q and our other reports and documents filed with the SEC from time to time.
Overview
Frontier Airlines, Inc. (“Frontier”) is an ultra low-cost carrier whose business strategy is focused on Low Fares Done Right. We are headquartered in Denver, Colorado and offer flights throughout the United States and to select international destinations in the Americas. Our unique strategy is underpinned by our low-cost structure and superior low-fare brand.
The following table provides select financial and operational information for the three and six months ended June 30, 2024 and 2023, respectively (in millions):
Three Months Ended June 30,Six Months Ended June 30,

Income (loss) before income taxes$32 $88 $$71 
Available seat miles (“ASMs”)10,552 9,337 19,998 18,112 
Total operating revenues for the three and six months ended June 30, 2024 totaled $973 million and $1,838 million, respectively, an increase of 1% compared to each of the three and six months ended June 30, 2023, respectively. This was primarily due to an increase in capacity, as measured by ASMs, partially offset by a reduction in revenue per available seat mile (“RASM”) for the three and six months ended June 30, 2024 as compared to the corresponding prior year periods.
Total operating expenses during the three and six months ended June 30, 2024 totaled $948 million and $1,844 million, respectively, resulting in a cost per available seat mile (“CASM”) of 8.98¢ and 9.22¢, compared to 9.51¢ and 9.72¢ for the three and six months ended June 30, 2023, respectively. Fuel expense was 18% and 3% higher, respectively, as compared to the corresponding prior year periods. The $44 million increase in fuel expense for the three months ended June 30, 2024 as compared to the corresponding prior year period was primarily driven by a 13% increase in fuel gallons consumed as a result of our 13% capacity increase and a 6% increase in fuel cost per gallon. The $15 million increase in fuel expense for the six months ended June 30, 2024 as compared to the corresponding prior year period was primarily driven by a 9% increase in fuel gallons consumed as a result of our 10% increase in capacity partially offset by a 6% reduction in fuel cost per gallon.
Our non-fuel expenses increased by 2% and 6% during the three and six months ended June 30, 2024, respectively, as compared to the corresponding prior year periods, driven primarily by higher capacity and larger fleet size and the resulting increase in operations during the same periods partially offset by increased sale-leaseback gains, lower lease return costs and lower maintenance, materials and repairs costs. While non-fuel expenses

increased by $16 million and $68 million, CASM (excluding fuel), a non-GAAP measure, decreased by 10% and 5% to 6.24¢ and 6.46¢ for the three and six months ended June 30, 2024, respectively. The decrease in CASM (excluding fuel) on increased ASMs of 13% and 10% for the three and six months ended June 30, 2024, respectively, as compared to the corresponding prior year periods, was due to an increase in sale-leaseback gains compared to the corresponding prior year periods as well as a decrease in aircraft rent expense due to lease extension events and a decrease in maintenance, materials and repairs primarily due to lower contract labor costs partially offset by an increase in station costs due to a lower stage length on higher departures. Additionally, for the six months ended June 30, 2024, CASM (excluding fuel) was unfavorably impacted by higher crew costs including other benefits and increased salaried support staff expenses. For the reconciliation to corresponding GAAP measures, see “Results of Operations—Reconciliation of CASM to CASM (excluding fuel), Adjusted CASM (excluding fuel), Adjusted CASM, Adjusted CASM including net interest and CASM including net interest.”
We generated net income of $31 million and $5 million during the three and six months ended June 30, 2024, respectively, compared to net income of $71 million and $58 million for the three and six months ended June 30, 2023, respectively.
As of June 30, 2024, our total available liquidity was $658 million, made up of cash and cash equivalents.

Total operating revenue increased $6 million, or 1%, during the three months ended June 30, 2024 as compared to the three months ended June 30, 2023. While capacity grew by 13%, as measured by ASMs, revenue was unfavorably impacted by the 11% reduction in RASM due to a 14% decline in total revenue per passenger as well as a 7.2 point reduction in load factor. Revenue per passenger reflected weak domestic pricing as seat growth outpaced seasonal demand and the above-average concentration of capacity allocated to new markets which also led to lower load factors. The increase in capacity was driven by an 18% increase in average aircraft in service during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023, partially offset by a 13% decrease in average stage length to 899 miles compared to 1,038 miles for the corresponding prior year period.

(b)CASM (excluding fuel) and Adjusted CASM (excluding fuel) are included as supplemental disclosures because we believe that excluding aircraft fuel is useful to investors as it provides an additional measure of management’s performance excluding the effects of a significant cost item over which management has limited influence. The price of fuel, over which we have limited control, impacts the comparability of period-to-period financial performance, and excluding the price of fuel allows management an additional tool to understand and analyze our non-fuel costs and core operating performance, and increases comparability with other airlines that also provide a similar metric. CASM (excluding fuel) and Adjusted CASM (excluding fuel) are not determined in accordance with GAAP and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.
(c)Adjusted CASM is included as supplemental disclosure because we believe it is a useful metric to properly compare our cost management and performance to other peers, as derivations of Adjusted CASM are well-recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in the airline industry. Additionally, we believe this metric is useful because it removes certain items that may not be indicative of base operating performance or future results. Adjusted CASM is not determined in accordance with GAAP, may not be comparable across all carriers and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.
(d)Adjusted CASM including net interest and CASM including net interest are included as supplemental disclosures because we believe they are useful metrics to properly compare our cost management and performance to other peers that may have different capital structures and financing strategies, particularly as it relates to financing primary operating assets such as aircraft and engines. Additionally, we believe these metrics are useful because they remove certain items that may not be indicative of base operating performance or future results. Adjusted CASM including net interest and CASM including net interest are not determined in accordance with GAAP, may not be comparable across all carriers and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.
Aircraft Fuel. Aircraft fuel expense increased by $44 million, or 18%, during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023. The increase was primarily due to an increase of 13% in fuel gallons consumed due to higher capacity and a 6% growth in fuel cost per gallon.
Salaries, Wages and Benefits. Salaries, wages and benefits expense increased by $33 million, or 16%, during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023. The increase was

primarily due to higher crew costs, driven by elevated credit hours on higher capacity and other benefit costs, as well as increased headcount of salaried support staff, as compared to the corresponding prior year period.
Aircraft Rent. Aircraft rent expense decreased by $1 million, or 1%, during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023, primarily due a decrease in lease return costs caused by aircraft lease extension events that occurred in the current period as well as the ongoing benefit from extensions in prior periods, which was mostly offset by a larger fleet.
Station Operations. Station operations expense increased by $39 million, or 31%, during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023, primarily due to increased airport operations as a result of the 26% increase in departures and 17% increase in passengers.
Maintenance, Materials and Repairs. Maintenance, materials and repair expense decreased by $10 million, or 19%, during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023. This decrease was primarily due to lower contract labor costs, partially offset by the 18% increase in average aircraft in service, resulting in higher aircraft maintenance costs.
Sales and Marketing. Sales and marketing expense increased by $3 million, or 7%, during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023, primarily due an increase in customer reservation system fees and paid media advertising.

Depreciation and Amortization. Depreciation and amortization expense increased by $6 million, or 50%, during the three months ended June 30, 2024, as compared to the three months ended June 30, 2023, primarily due to an increase in capitalized maintenance depreciation due to the increase in fleet size as well as a gain on asset disposal during the comparable prior year period.
Other Operating. Other operating resulted in a net gain of $1 million during the three months ended June 30, 2024, as compared to an expense of $53 million during the three months ended June 30, 2023. This movement was primarily driven by the increase in sale-leaseback gains compared to the corresponding prior year period, as a result of six aircraft inductions and two engine inductions subject to sale-leaseback transactions in the current period compared to one aircraft induction and one engine induction subject to sale-leaseback transactions in the corresponding prior year period.
Other Income (Expense). Other income decreased by $2 million, or 22%, during the three months ended June 30, 2024, as compared the three months ended June 30, 2023. The decrease was primarily due to lower interest income from lower balances in interest-bearing cash accounts and increased interest expense, driven mainly by higher interest rates and higher principal balances on our debt, partially offset by greater capitalized interest due to higher interest rates.
Income Taxes. Our effective tax rate for the three months ended June 30, 2024 was an expense of 3.1%, compared to an expense of 19.3% for the three months ended June 30, 2023, on pre-tax net income for both periods. The primary difference between the effective tax rate and the federal statutory rate is related to a decrease in our valuation allowance relating to federal and state net operating losses.
