ALLEGIANT TRAVEL COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)
Note 1 — Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited consolidated financial statements include the accounts of Allegiant Travel Company (the “Company”) and its majority-owned operating subsidiaries. The Company's investments in unconsolidated affiliates, which are 50 percent or less owned, are accounted for under the equity or cost method, and are insignificant to the consolidated financial statements. All intercompany balances and transactions have been eliminated.
These unaudited consolidated financial statements reflect all normal recurring adjustments which management believes are necessary to present fairly 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 consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission for Form 10-Q. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company and notes thereto included in the annual report of the Company on Form 10-K for the year ended December 31, 2023 and filed with the Securities and Exchange Commission.
The preparation of 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 financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates.
The Company has reclassified certain prior period amounts to conform to the current period presentation.
Note 2 — Special Charges
Sunseeker Resort
As a result of Hurricane Ian's direct hit on the southwest coast of Florida on September 28, 2022, the construction site of Sunseeker Resort at Charlotte Harbor (the "Resort" or "Sunseeker Resort") was damaged. There was a subsequent weather-related event and a fire that caused additional damage in fourth quarter 2022. In addition, during third quarter 2023, the Sunseeker Resort construction site sustained additional damages related to Hurricane Idalia. The Company recorded estimated losses in 2022 and 2023 based on its assessment of these damages and the anticipated future restoration cost. The estimated losses were recorded to special charges and are offset by insurance recoveries in the period they are approved. To date, the Company has recorded $78.3 million in losses and $54.5 million in insurance recoveries. The Company has submitted additional insurance claims that remain outstanding at the date of this report.
Airline
Due to the heavy maintenance needs on certain aging Airbus airframes and capacity constraints at the maintenance, repair, and overhaul contractors, the Company reevaluated its fleet plan and identified 21 airframes for early retirement to coincide with 737 MAX aircraft deliveries as scheduled under an amendment to the Company's agreement with The Boeing Company signed in September 2023. Two airframes were retired in 2023 and two airframes were retired in first quarter 2024. The remaining airframes are to be retired between August 2024 and December 2026. The accelerated depreciation on these airframes resulting from a change in the estimated useful life is recorded as a special charge.
In April 2024, the Company and the Transport Workers Union of America, representing the Company's flight attendants, ratified a new five-year collective bargaining agreement. The ratification bonus related to this new collective bargaining agreement, paid in May 2024, is included within special charges.

Note 3 — Revenue Recognition
Passenger Revenue
Passenger revenue is the most significant category in the Company's reported operating revenues, as outlined below:

| Three Months Ended June 30, |  | Six Months Ended June 30,
(in thousands) | 2024 |  | 2023 |  | 2024 |  | 2023
Scheduled service | $ | 272,715 |  |  | $ | 319,338 |  |  | $ | 562,594 |  |  | $ | 631,065 |
Ancillary air-related charges | 307,390 |  |  | 309,735 |  |  | 582,183 |  |  | 593,637 |
Loyalty redemptions | 14,394 |  |  | 13,674 |  |  | 29,657 |  |  | 27,321 |
Total passenger revenue | $ | 594,499 |  |  | $ | 642,747 |  |  | $ | 1,174,434 |  |  | $ | 1,252,023 |

Sales of passenger tickets not yet flown are recorded in air traffic liability. Passenger revenue is recognized when the underlying service is provided. As of June 30, 2024, the air traffic liability balance was $390.0 million, of which approximately $341.6 million was related to forward bookings, with the remaining $48.4 million related to credit vouchers for future travel.
The normal contract term of passenger tickets is 12 months and passenger revenue associated with future travel will principally be recognized within this time frame. Of the $353.5 million that was recorded in the air traffic liability balance as of December 31, 2023, approximately 86.1 percent was recognized into passenger revenue during the six months ended June 30, 2024.
The Company periodically evaluates the estimated amount of credit vouchers expected to expire unused and any adjustment is removed from air traffic liability and included in passenger revenue in the period in which the evaluation is complete.
Resort Revenue
The Company's resort revenues for the three and six months ended June 30, 2024 are set forth in the table below:

| Three Months Ended June 30, |  | Six Months Ended June 30,
(in thousands) | 2024 |  | 2023 |  | 2024 |  | 2023
Food and beverage | $ | 7,643 |  |  | $ | — |  |  | $ | 18,415 |  |  | $ | — |
Rooms | 6,653 |  |  | — |  |  | 16,610 |  |  | — |
Other | 2,515 |  |  | — |  |  | 5,673 |  |  | — |
Total resort revenue | $ | 16,811 |  |  | $ | — |  |  | $ | 40,698 |  |  | $ | — |

Revenue from banquets, golf, retail and spa services are included in other resort revenue. Resort revenue is recognized as the underlying services or goods have been provided. There is typically little to no lag between when the services are performed and when payment is remitted. Large group reservations, conventions, and other event bookings require advance deposits which are recorded as accrued liabilities in the Company's balance sheet until the related services and goods are provided. Guest receivables are recorded in accounts receivable on the Company's balance sheet for room nights stayed prior to payment at checkout. The amounts of advance deposit liabilities and guest ledger receivables were not material as of June 30, 2024 or December 31, 2023.
Loyalty redemptions
10

In relation to the travel component of the Allways Rewards® co-brand credit card contract, the Company has a performance obligation to provide point holders with future travel award redemptions at the airline and resort. Therefore, consideration received related to the travel component is deferred based on its relative selling price and is recognized into passenger revenue or resort revenue when the points are redeemed and the underlying service is provided. Similarly, in relation to the Allways Rewards loyalty program, points earned through the program are deferred based on the stand-alone selling price and recognized into passenger or resort revenue when the points are redeemed and the underlying service is provided.
The following table presents the activity of the point liability for the periods indicated:

| Six Months Ended June 30,
(in thousands) | 2024 |  | 2023
Points balance at January 1 | $ | 70,813 |  |  | $ | 56,500 |
Points awarded (deferral of revenue) | 33,272 |  |  | 35,666 |
Points redeemed (recognition of revenue) | (29,674) |  |  | (27,321) |
Points balance at June 30 | $ | 74,411 |  |  | $ | 64,845 |

The current portion of the loyalty program liability represents the estimate of revenue to be recognized in the next 12 months based on historical trends, with the remaining balance reflected in noncurrent liabilities expected to be recognized into revenue in periods thereafter.

Debt Secured by Aircraft
During the six months ended June 30, 2024, the Company received $18.8 million in advances on a pre-delivery payment (PDP) credit facility secured by certain of the Company's Boeing aircraft purchase rights. The notes under the facility bear interest at a floating interest rate based on SOFR and mature on June 30, 2025 or upon delivery of the applicable aircraft.
12

Other Secured Debt
In March 2024, the Company entered into credit agreements for up to $218.5 million which will be collateralized by new aircraft upon delivery. The loans will bear interest at a variable rate based on 3-month SOFR and are payable in quarterly installments for a term of 12 years. No draws have been made on these financing commitments to date.
Note 6 — Income Taxes
The Company recorded a $4.3 million income tax expense at a 24.0 percent effective tax rate and a $27.9 million income tax expense at a 24.0 percent effective tax rate for the three months ended June 30, 2024 and 2023, respectively. The effective tax rate for the three months ended June 30, 2024 differed from the statutory federal income tax rate of 21.0 percent primarily due to state income taxes, permanent tax differences, and discrete items, none of which are individually significant.
The Company recorded a $3.9 million income tax expense at an effective tax rate of 23.4 percent and a $46.1 million income tax expense at a 24.2 percent effective tax rate for the six months ended June 30, 2024 and 2023, respectively. The effective tax rate for the six months ended June 30, 2024 differed from the statutory Federal income tax rate of 21.0 percent primarily due to state income taxes and the impact of permanent tax differences, none of which are individually significant. During the six months ended June 30, 2024, the Company recognized a $0.6 million income tax expense for discrete items.
While the Company expects its effective tax rate to be fairly consistent in the near term, it will vary depending on recurring items such as the amount of income earned in each state and the state tax rate applicable to such income. Discrete items during interim periods may also affect the Company's tax rates.
Note 7 — Fair Value Measurements
The Company utilizes the market approach to measure the fair value of its financial assets. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets. The assets classified as Level 2 primarily utilize quoted market prices or alternative pricing sources including transactions involving identical or comparable assets and models utilizing market observable inputs for valuation of these securities. No changes in valuation techniques or inputs occurred during the six months ended June 30, 2024.
Financial instruments measured at fair value on a recurring basis:

None of the Company's debt is publicly held and as a result, the Company has determined the estimated fair value of these notes as Level 3 liabilities. Certain inputs used to determine fair value are unobservable and, therefore, could be sensitive to changes in inputs. The Company utilizes the discounted cash flow method to estimate the fair value of Level 3 debt.
The carrying value and estimated fair value of long-term debt, excluding finance leases, including current maturities and without reduction for related costs, are as follows:

| As of June 30, 2024 |  | As of December 31, 2023 |  |
(in thousands) | Carrying Value |  | Estimated Fair Value |  | Carrying Value |  | Estimated Fair Value |  | Hierarchy Level
Fair Value of Notes Payable | $ | 1,794,950 |  |  | $ | 1,713,681 |  |  | $ | 1,826,921 |  |  | $ | 1,815,351 |  |  | 3

Due to their short-term nature, the carrying amounts of cash, restricted cash, accounts receivable and accounts payable approximate fair value.
Note 8 — Earnings per Share
Basic and diluted earnings per share are computed pursuant to the two-class method. Under this method, the Company attributes net income to two classes: common stock and unvested restricted stock. Unvested restricted stock awards granted to employees under the Company’s Long-Term Incentive Plan are considered participating securities as they receive non-forfeitable rights to cash dividends at the same rate as common stock.
Diluted net income per share is calculated using the more dilutive of the two methods. Under both methods, the exercise of employee stock options is assumed using the treasury stock method. The assumption of vesting of restricted stock, however, differs:
1.Assume vesting of restricted stock using the treasury stock method.
2.Assume unvested restricted stock awards are not vested, and allocate earnings to common shares and unvested restricted stock awards using the two-class method.
The following table sets forth the computation of net income per share, on a basic and diluted basis, for the periods indicated (share count and dollar amounts other than per-share amounts in the table are in thousands):

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis presents factors that had a material effect on our results of operations during the three and six months ended June 30, 2024 and 2023. Also discussed is our financial position as of June 30, 2024 and December 31, 2023. You should read this discussion in conjunction with our unaudited consolidated financial statements, including the notes thereto, appearing elsewhere in this Form 10-Q and our consolidated financial statements appearing in our annual report on Form 10-K for the year ended December 31, 2023. This discussion and analysis contains forward-looking statements. Please refer to the section below entitled “Cautionary Note Regarding Forward-Looking Statements” for a discussion of the uncertainties, risks and assumptions associated with these statements.
Second Quarter 2024 Review
Second quarter 2024 highlights include:
•Operating income of $34.9 million, yielding an operating margin of 5.2 percent
•Total operating revenue of $666.3 million, down 2.6 percent from second quarter 2023
•Total fixed fee contracts revenue of $17.7 million, up 50.7 percent over second quarter 2023
•Total average ancillary fare of $75.34, up 5.0 percent over second quarter 2023 driven by strength in seats, bags, and cobrand credit card revenue
•Our flight attendants ratified a new five-year contract negotiated with the Transportation Workers Union
•Airline special charges of $20.1 million including a ratification bonus of $10.8 million (including related payroll tax expense) paid to flight attendants and accelerated depreciation due to early aircraft retirement plan of $9.3 million

•Enrolled 552 thousand new Allways Rewards members during the second quarter 2024
•Airline-only operating CASM excluding fuel and special charges of 8.23 cents, up 5.6 percent over second quarter 2023
•Named best low-cost carrier in North America by Skytrax, the international air transport rating organization
•In July 2024, we announced eight new routes which will bring the number of total routes served to 558
AIRCRAFT
The following table sets forth the aircraft in service and operated by us as of the dates indicated:

| June 30, 2024 |  | December 31, 2023 |  |
A320(1)(2) | 92 |  |  | 92 |  |  |
A319(3) | 34 |  |  | 34 |  |  |
Total | 126 |  |  | 126 |  |  |

(1)December 31, 2023 figure does not include one aircraft of which we had taken delivery, but was not in service as of that date.
(2)Includes 23 aircraft under finance lease and 13 aircraft under operating lease as of June 30, 2024, and December 31, 2023.
(3)Includes four aircraft under operating lease as of June 30, 2024 and December 31, 2023.
As of June 30, 2024, we are a party to forward purchase agreements for 50 aircraft with four deliveries currently expected in 2024, and the remaining 46 aircraft are expected to be delivered in 2025 and later years. The timing of these deliveries is based on management's best estimates at the current time and differs from the contract in place. The delivery schedule has been and will continue to be impacted by delay notices from Boeing and continuing regulatory reviews of Boeing.
Due to the heavy maintenance needs on certain aging Airbus airframes and capacity constraints at the maintenance, repair, and overhaul contractors, we reevaluated our fleet plan and identified 21 aging airframes for early retirement to coincide with the delivery schedule for our 737 MAX aircraft provided in an amendment to our Boeing purchase agreement signed in September 2023. Two airframes were retired in 2023 and two airframes were retired in first quarter 2024. The remaining airframes are to be retired between August 2024 and December 2026. The timing of the retirements has been coordinated with the revised delivery schedule for the 737 MAX aircraft to provide us with opportunities for fleet renewal and replacement. The accelerated depreciation on these airframes resulting from a change in the estimated useful life is recorded as a special charge of $9.3 million during second quarter 2024. We plan to retain the engines associated with these airframes in our spare engine pool and use the substantial remaining life on these engines to offset future overhaul costs.
18

NETWORK
As of June 30, 2024, we were selling 550 routes versus 555 as of the same date in 2023. Growth of our network has been impacted by challenges created by delayed aircraft deliveries, the uncertainty of our pilot staffing levels and other factors. We have identified over 1,400 incremental domestic nonstop routes as opportunities for future network growth, of which over 77 percent currently have no non-stop service. Our total active number of origination cities and leisure destinations were 90 and 34, respectively, as of June 30, 2024.
Our unique model is predicated around expanding and contracting capacity to meet seasonal leisure travel demands.
TRENDS
Aircraft Fuel
The cost of fuel is volatile, as it is subject to many economic and geopolitical factors we can neither control nor predict. Significant increases in fuel costs could materially affect our operating results and profitability. We have not sought to use financial derivative products to hedge our exposure to fuel price volatility, nor do we have any plans to do so in the future.
The cost per gallon of fuel began to increase significantly in 2021, and the increases were exacerbated by the geopolitical impact of the war in Ukraine. The average fuel cost per gallon increased 5.2 percent in second quarter 2024 compared to the same period in 2023 and remained 40.1 percent higher than in second quarter 2021. We expect high fuel costs to continue impacting our total costs and operating results.
Boeing Agreement
We have signed an agreement and amendments with The Boeing Company to purchase 50 newly manufactured 737 MAX aircraft with options to purchase up to an additional 80 737 MAX aircraft. We believe this new aircraft purchase is complementary with our low-cost strategy based on our intent to retain ownership of the aircraft, the longer useful life for depreciation purposes, and expected fuel savings and operational reliability from the use of these new aircraft.
In the interest of increased quality control at Boeing and its suppliers, the Federal Aviation Administration (FAA) has indicated aircraft production rates will be capped until they are satisfied with Boeing's quality practices. These factors and other delays in Boeing obtaining needed regulatory approvals could delay deliveries to us even further than management's current expectations. Although the contract provides for more deliveries, we do not expect more than four aircraft to be delivered in 2024. Continuing delays in aircraft deliveries will impact our ability to schedule additional growth into 2025.
Capacity Growth
Capacity growth may also be impacted by aircraft in heavy maintenance, uncertainty as to pilot staffing levels and airport construction disruption. We believe these issues are not unique to Allegiant.
Increasing Utilization
We are in the midst of an effort to increase aircraft utilization back to 2019 levels by adding service to our schedule in our most profitable peak periods. By way of example, our aircraft utilization rate was 9.7 hours per aircraft in June 2019 and even with an approximate one-half hour increase over June 2023, utilization was only 7.8 hours per aircraft in June 2024. We currently expect to achieve this goal during 2025, but this effort is subject to various risks, some of which may not be under our control.
New Reservation System
During 2023, we converted to the Navitaire reservation system to replace our legacy home-grown system. While we expect incremental passenger revenue once this system is fully implemented, we suffered some per passenger air ancillary revenue degradation (in the area of bundled ancillary products in particular) as certain functionality was unavailable during the transition. We are devoting resources to the transition issues and currently expect to regain the lost per passenger revenue and achieve some of the incremental per passenger revenue in 2025.
Union Negotiations
The collective bargaining agreement with our pilots is currently amendable. We and the International Brotherhood of Teamsters ("IBT”) jointly requested the mediation services of the National Mediation Board ("NMB") in January 2023 to assist with the negotiations. The mediation process with the NMB is continuing with new union negotiators and leadership, with negotiation sessions currently scheduled through October 2024.
Separately from the ongoing collective bargaining agreement negotiations, to address retention and pilot pay issues and increase pilot staffing levels, effective in May 2023, we began recognizing a retention bonus for pilots who continue employment with us until a new labor agreement is approved. The amount being accrued is 35 percent of current hourly pay rates, except for our first year first officers for whom the percentage is 82 percent, in each case, calculated at a minimum of 85 pay credit hours per month. The IBT concurred with this approach. Our implementation of the retention bonus successfully allowed us to
19

effectively increase pay rates for our pilot team members (by way of the accrual of the retention bonus), add pilots through hiring and significantly slow attrition.
For the three months ended June 30, 2024, we recorded estimated pilot retention bonus accruals of $23.7 million bringing the total accrual to $100.6 million at period end, including the related payroll taxes. The bonus will be paid to all pilots remaining employed with us upon ratification of a new collective bargaining agreement.
On April 15, 2024, our flight attendants ratified a new five-year agreement we negotiated with the Transportation Workers Union (TWU). The new contract provides for immediate wage increases, improved pay overrides, an increased 401(k) match, and a $10.0 million ratification bonus ($10.8 million including the related payroll tax expense), which was paid out in May 2024. The agreement provides us with increased flexibility in scheduling flight attendants during irregular operations, which should increase productivity and reduce operational disruptions.
Sunseeker Resort
Sunseeker Resort at Charlotte Harbor opened in December 2023. As with many new hotels or resorts, Sunseeker's booking and occupancy rates are lower than more established properties. Despite strong performance by our food and beverage offerings, we expect Sunseeker to incur losses in its first year of operations. Our customer reviews to date have been positive and we hope to build on that favorable customer sentiment to achieve better financial performance of the Resort in the future. We have engaged experienced hospitality advisors to identify areas for improvement in an effort to seek to maximize the value of this asset and explore strategic alternatives.
Establishment of ESG Goals
We have established ESG goals in the areas of environmental, social and governance. We will report on our progress toward meeting those goals within our annual sustainability reports.
VivaAerobus Alliance
In December 2021, we announced plans for a fully-integrated commercial alliance agreement with VivaAerobus, designed to expand options for nonstop leisure air travel between our markets in the United States and Mexico. We and VivaAerobus have submitted a joint application to the Department of Transportation (DOT) requesting approval of and antitrust immunity for the alliance. Although the DOT process has progressed substantially, their review of our application is currently suspended pending the outcome of diplomatic engagement on broader treaty issues and, as a result, the timing of commencement of this service is uncertain as it will depend on when or if the DOT will ultimately approve the grant of antitrust immunity.

RESULTS OF OPERATIONS
Comparison of three months ended June 30, 2024 to three months ended June 30, 2023
Operating Revenue
Passenger revenue. Second quarter 2024 passenger revenue decreased by 7.5 percent compared to the same period in 2023 on a slight decrease in capacity. The decrease in passenger revenue was primarily driven by an 11.0 percent decrease in average scheduled service base fare, coupled with a 3.1 percent decrease in passengers flown, compared to second quarter 2023. The lower base fare is attributable to weaker demand in off-peak periods. Air ancillary revenue per passenger increased by 2.4 percent over second quarter 2023 partially offsetting decreases in base fare and the 3.1 percent decrease in passengers flown.
Third party products revenue. Third party products revenue for second quarter 2024 increased 28.4 percent compared to second quarter 2023. The increase from 2023 is primarily the result of a 41.7 percent increase in the marketing component of co-brand credit card revenues and $2.1 million of revenue from a new travel insurance product implemented during first quarter 2024.
Fixed fee contract revenue. Fixed fee contract revenue for second quarter 2024 increased 50.7 percent compared to the same period in 2023 on a 51.1 percent increase in fixed fee departures as the result of strong performance and growth in corporate and military charters and other sports flying.
Operating Expenses
We primarily evaluate our expense management by comparing our costs per available seat mile (ASM) across different periods, which enables us to assess trends in each expense category. The following table presents unit costs on a per ASM basis, or CASM, for the indicated periods. Excluding fuel on a per ASM basis provides management and investors the ability to measure and monitor our cost performance absent fuel price volatility. Both the cost and availability of fuel are subject to many economic and political factors beyond our control. Excluding special charges and Sunseeker operating costs also allows management and investors to better compare our airline unit costs with those of other airlines.

Operating CASM, excluding fuel, airline special charges, and Sunseeker Resort activity. Operating CASM, excluding fuel, airline special charges and Sunseeker Resort activity ("CASM-ex"), increased by 5.6 percent to 8.23 ¢ for second quarter 2024 from 7.79 ¢ in second quarter 2023. The CASM-ex increase is primarily attributable to a 12.8 percent or $22.5 million increase in airline salaries and benefits expense in second quarter 2024 over second quarter 2023 (for the reasons described in the expense line item discussion below). This increase was on relatively flat capacity (a decrease of 0.8 percent) as we continue to manage capacity to meet demand while navigating other constraints to airline growth.
Salaries and benefits expense. Salaries and benefits expense increased $32.8 million, or 18.5 percent, in second quarter 2024 compared to second quarter 2023. Higher salaries and benefits expense was primarily driven by a 10.2 percent increase in airline full time equivalent employees (including a 25.5 percent increase in the number of pilots employed since June 30, 2023) and increased crew pay. Increased crew pay reflects the impact of a $23.7 million accrual for pilot retention bonuses during second quarter 2024 which exceeds the second quarter 2023 accrual by $11.9 million, and a new collective bargaining agreement with our flight attendants that includes wage increases effective April 2024. The accrued pilot retention bonus is
21

payable after ratification of a new collective bargaining agreement with this work group. The grand opening of Sunseeker Resort in December 2023 further drove the increase by adding nearly 900 Resort team members and an increase of $10.3 million in salaries and benefits expense in second quarter 2024.
Aircraft fuel expense. Aircraft fuel expense increased $7.4 million, or 4.6 percent, for second quarter 2024 compared to second quarter 2023. This is primarily due to a 5.2 percent increase in average fuel cost per gallon, offset by a 0.6 percent decrease in fuel gallons consumed from a 0.8 percent decrease in total available seat miles.
Station operations expense. Station operations expense for second quarter 2024 increased $3.1 million, or 4.6 percent compared to second quarter 2023 primarily due to a $3.4 million increase in airport rent and landing fees on a relatively flat number of departures.
Depreciation and amortization expense. Depreciation and amortization expense for second quarter 2024 increased by $11.4 million or 21.2 percent compared to second quarter 2023. The increase is primarily related to $6.0 million of depreciation expense related to the Sunseeker Resort, a $2.5 million increase in heavy maintenance amortization, and an increase of $2.0 million in capitalized software depreciation related to new IT systems placed in service beginning in the second half of 2023.
Maintenance and repairs expense. Maintenance and repairs expense for second quarter 2024 decreased $2.9 million, or 8.6 percent, compared to second quarter 2023, due to stabilized staffing which resulted in decreased outsourced labor expenses coupled with a decrease in rotable repairs. On a per ASM basis, maintenance and repairs expense decreased 9.0 percent year over year.
Sales and marketing expense. Sales and marketing expense for second quarter 2024 decreased by $2.4 million or 7.9 percent compared to the same period in 2023. The change was primarily driven by a fee paid to transition our cobrand credit card to a new payment network during second quarter 2023 and by a 7.5 percent decline in passenger revenue year over year which drove a reduction in credit card processing fees.
Other operating expense. Other operating expense increased $2.5 million or 7.7 percent in second quarter 2024 compared to second quarter 2023. The increase was driven by an $8.1 million increase in Sunseeker Resort operating expenses consisting of $2.4 million cost of sales (primarily food and beverage cost), $2.2 million insurance, $0.7 million property taxes, and other general and administrative expenses, and incremental software licenses, training, and support related to new IT systems. These increases were offset in part by gains on the sale of property and equipment.
Special charges. During second quarter 2024, we recorded $18.1 million of special charges including $9.3 million of accelerated depreciation from the early retirement of 21 airframes through 2026 pursuant to a revised fleet plan and $10.8 million related to the ratification bonus on our new flight attendant collective bargaining agreement, which was offset by $2.0 million of net insurance recoveries related to Sunseeker Resort hurricane damages.
Interest Expense and Income
Interest expense, net of interest income and capitalized interest, for the quarter ended June 30, 2024 remained relatively flat over second quarter 2023. Interest expense for the quarter increased by $1.8 million over the prior year quarter primarily due to a $58.5 million increase in outstanding principal. The increase in interest expense was offset by a $2.7 million increase in capitalized interest driven by increased pre-delivery deposits on aircraft and a $0.7 million decrease in interest income.
Income Tax Expense
We recorded a $4.3 million income tax expense at an effective tax rate of 24.0 percent and a $27.9 million income tax expense at a 24.0 percent effective tax rate for the three months ended June 30, 2024 and 2023, respectively. The effective tax rate for the three months ended June 30, 2024 differed from the statutory federal income tax rate of 21.0 percent primarily due to state income taxes and permanent tax differences.

Comparison of six months ended June 30, 2024 to six months ended June 30, 2023
Operating Revenue
Passenger revenue. For the six months ended June 30, 2024, passenger revenue decreased $77.6 million or 6.2 percent compared with the same period in 2023 on relatively flat capacity. The decrease in passenger revenue was primarily driven by an 8.0 percent decrease in average scheduled service base fare coupled with a 2.3 percent decrease in passengers flown. The lower base fare is attributable to weaker demand in off-peak periods.
Third party products revenue. Third party products revenue for the six months ended June 30, 2024 increased $15.6 million or 28.3 percent over the same period in 2023. The increase from 2023 is primarily the result of a 38.4 percent increase in the marketing component of co-brand credit card revenues and $4.7 million of revenue from a new travel insurance product implemented during first quarter 2024.
Fixed fee contract revenue. Fixed fee contract revenue for the six months ended June 30, 2024 increased $10.7 million or 41.4 percent compared to the same period in 2023 on a 49.7 percent increase in fixed fee departures as a result of strong performance during March Madness and growth in corporate and military charters and other sports flying.
Operating Expenses
The following table presents unit costs on a per ASM basis, defined as Operating CASM, for the indicated periods. Excluding fuel on a per ASM basis provides management and investors the ability to measure and monitor our cost performance absent fuel price volatility. Both the cost and availability of fuel are subject to many economic and political factors beyond our control. Excluding special charges and Sunseeker operating costs allows management and investors to better compare our airline unit costs with those of other airlines.

Operating CASM, excluding fuel, airline special charges, and Sunseeker Resort activity. Operating CASM, excluding fuel, airline special charges and Sunseeker Resort activity, increased by 9.9 percent to 8.54 ¢ for the six months ended June 30, 2024 from 7.77 ¢ for the same period in 2023. The CASM-ex increase is primarily attributable to a 19.4 percent or $64.4 million increase in airline salaries and benefits expense (for the reasons described in the expense line item discussion below). This increase was on relatively flat capacity (an increase of 0.6 percent) as we continue to manage capacity to meet demand while navigating other constraints to airline growth.
Salaries and benefits expense. Salaries and benefits expense increased $86.5 million, or 25.7 percent, for the six months ended June 30, 2024 compared to the same period in 2023. Higher salaries and benefits expense was primarily driven by a 10.2 percent increase in airline full-time equivalent employees (including a 25.5 percent increase in the number of pilots employed since June 30, 2023) and increased crew pay. Increased crew pay includes the impact of a $46.0 million accrual for pilot retention bonuses during the six months ended June 30, 2024, of which $34.2 million is incremental to what was accrued in the same period in 2023, and a new collective bargaining agreement with our flight attendants that includes wage increases effective April 2024. The accrued pilot retention bonus is payable after completion of a new collective bargaining agreement with this work
23

group. The grand opening of Sunseeker Resort in December 2023 further drove the increase by adding nearly 900 Resort team members and an increase of $22.0 million in salaries and benefits expense during the six month period.
Aircraft fuel expense. Aircraft fuel expense decreased $12.0 million, or 3.4 percent, for the six months ended June 30, 2024 compared to the same period in 2023. This is primarily driven by a 3.9 percent decrease in average fuel cost per gallon. The decrease in fuel cost was partially offset by a 0.4 percent increase in fuel gallons consumed on a 0.6 percent increase in total available seat miles.
Station operations expense. Station operations expense for the six months ended June 30, 2024 increased $8.0 million or 6.3 percent primarily driven by a $6.3 million increase in airport rent and landing fees on a relatively flat number of departures.
Depreciation and amortization expense. Depreciation and amortization expense for the six months ended June 30, 2024 increased $20.6 million or 19.0 percent as compared to the same period in 2023 due to $11.8 million of incremental depreciation related to the Sunseeker Resort, an increase of $4.6 million in deferred heavy maintenance amortization, and an increase of $2.1 million in capitalized software depreciation related to new IT systems placed in service beginning in the second half of 2023.
Maintenance and repairs expense. Maintenance and repairs expense for the six months ended June 30, 2024 increased $0.9 million or 1.6 percent in line with the 1.5 percent increase in average aircraft in service during the period. On a per ASM basis, maintenance and repairs remained flat year over year.
Sales and marketing expense. Sales and marketing expense for the six months ended June 30, 2024 increased $1.6 million or 2.8 percent compared to the same period in 2023, primarily driven by a year over year increase of $3.0 million in advertising and marketing for the Sunseeker Resort. These increases were offset in part by a reduction in credit card processing fees as a result of a 6.2 percent decrease in passenger revenue year-over-year and a fee paid to transition our co-brand credit card to a new payment network incurred during the 2023 period.
Other operating expense. Other expense for the six months ended June 30, 2024 increased by $18.8 million, or 30.1 percent year-over-year primarily due to an increase of $18.8 million related to Sunseeker Resort operations, which includes $6.0 million cost of sales (primarily food and beverage cost), $4.3 million of insurance expense, $1.6 million in property taxes, and other general and administrative expenses. The airline segment also saw increases in software licenses, training, and support related to our new IT systems, which were offset in part by gains on the sale of property and equipment.
Special charges. During the six months ended June 30, 2024, we recorded $31.2 million of special charges including $24.2 million of accelerated depreciation from the early retirement of 21 airframes through 2026 pursuant to a revised fleet plan and $10.8 million related to the ratification bonus on our new flight attendant collective bargaining agreement, which was offset by net insurance recoveries related to Sunseeker Resort hurricane damages of $3.8 million.
Interest Expense and Income
Interest expense, net of interest income and capitalized interest, for the six months ended June 30, 2024 decreased by $3.9 million, or 10.4 percent when compared to the same period in 2023. The decrease is primarily attributable to an $8.7 million increase in capitalized interest driven by increased pre-delivery deposits on aircraft and a $1.4 million increase in interest income, which were offset by a $6.2 million increase in interest expense on a year-over year increase of $58.5 million of debt outstanding and a 0.7 percentage point increase in weighted average variable interest rates.
Income Tax Expense
We recorded a $3.9 million income tax expense at an effective rate of 23.4 percent compared to a $46.1 million tax expense at a 24.2 percent effective tax rate for the six months ended June 30, 2024 and 2023, respectively. The 23.4 percent effective tax rate for the six months ended June 30, 2024 differed from the statutory federal income tax rate of 21.0 percent primarily due to state income taxes and the impact of permanent tax differences.

LIQUIDITY AND CAPITAL RESOURCES
Current liquidity
Cash, cash equivalents and investment securities (short-term and long-term) decreased slightly to $851.1 million as of June 30, 2024, from $870.7 million at December 31, 2023. Investment securities represent highly liquid marketable securities which are available-for-sale.
Restricted cash represents escrowed funds under fixed fee contracts and cash collateral against letters of credit required by hotel properties for guaranteed room availability, airports and certain other parties. Under our fixed fee flying contracts, we require our customers to prepay for flights to be provided by us. The prepayments are escrowed until the flight is completed and are recorded as restricted cash with a corresponding amount reflected as air traffic liability.
Our operating cash flows and long-term debt borrowings have allowed us to invest in our fleet renewal. Future capital needs are primarily for the acquisition of additional aircraft, including our existing aircraft commitments.
We believe we have more than adequate liquidity resources through our cash balances, operating cash flows, availability under revolving credit facilities, PDP facilities, and borrowings to meet our future contractual obligations. We have also entered into several financing commitments that will fund upon delivery of our new Boeing aircraft. We will continue to consider raising funds through debt financing as needed to fund capital expenditures.
Our current share repurchase authority is $75.7 million. We have not repurchased shares on the open market since December 2023. We have suspended our quarterly cash dividend in anticipation of upcoming capital needs related to our fleet investments.
Debt
Our debt and finance lease obligations balance, without reduction for related issuance costs, decreased by $44.5 million from $2.28 billion as of December 31, 2023 to $2.24 billion as of June 30, 2024. Net debt (total debt less unrestricted cash, cash equivalents, and investments) as of June 30, 2024 was $1.37 billion, a decrease of $21.2 million from December 31, 2023.
During the six months ended June 30, 2024, we entered into credit agreements for up to $218.5 million which will be collateralized by new aircraft deliveries. These commitments, along with commitments existing prior to first quarter 2024, are expected to refinance on a long-term basis $121.0 million of our PDP loan balances which are presently classified as current maturities of long term debt. No draws have been made on these financing commitments to date as they will be funded when the aircraft to be pledged are delivered to us.
As of June 30, 2024, approximately 80.5 percent of our debt and finance lease obligations are fixed-rate.
Sources and Uses of Cash
Operating Activities. Operating cash inflows are primarily derived from providing air transportation and related ancillary products and services to customers. During the six months ended June 30, 2024, our operating activities provided $236.7 million of cash compared to $346.6 million during the same period 2023. This change is primarily attributable to a $131.8 million decrease in net income compared to the 2023 period.
Investing Activities. Cash used for investing activities was $109.8 million during the six months ended June 30, 2024 compared to $517.8 million during the same period in 2023. The change is primarily attributable to a $211.5 million decrease in cash used for purchase of property and equipment, including aircraft PDPs and a $193.2 million increase in proceeds from maturities of investment securities, net of purchases, as proceeds from investment securities exceeded purchases in the first six months of 2024 but not the first six months of 2023.
Financing Activities. Cash used in financing activities for the six months ended June 30, 2024 was $54.4 million, compared to $94.4 million provided by financing activities during the same period in 2023. The change was primarily driven by a $189.4 million decrease in proceeds from issuance of debt offset by an $86.1 million decrease in principal repayments on long term debt and finance lease obligations. Other factors included a $38.1 million decrease in financing disbursements related to the Sunseeker construction loan and the payment of $21.9 million in cash dividends in 2024 compared to none in the same period in 2023 offset by a decrease of $12.4 million in cash used for common stock repurchases.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
We have made forward-looking statements in this quarterly report on Form 10-Q, and in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” that are based on our management’s beliefs and assumptions, and on information currently available to our management. Forward-looking statements include our statements regarding the number of contracted aircraft to be placed in service in the future, the timing of aircraft deliveries and retirements, our ability to increase aircraft utilization and also to increase per passenger revenue with our new revenue management system, the implementation of a joint alliance with VivaAerobus, the operations of our Sunseeker Resort, as well as other information concerning future results of operations, business strategies, financing plans, competitive position, industry environment, potential growth opportunities, the effects of future regulation and the effects of competition. Forward-looking statements include all statements that are not historical facts and can be identified by the use of forward-looking terminology such as the words "believe," "expect," "anticipate," "intend," "plan," "estimate," “project,” “hope” or similar expressions.
Forward-looking statements involve risks, uncertainties and assumptions. Actual results may differ materially from those expressed in the forward-looking statements. Important risk factors that could cause our results to differ materially from those expressed in the forward-looking statements may be found in our periodic reports filed with the Securities and Exchange Commission at www.sec.gov. These risk factors include, without limitation, the impact of regulatory reviews of Boeing on its aircraft delivery schedule, an accident involving, or problems with, our aircraft, public perception of our safety, our reliance on our automated systems, our reliance on Boeing and other third parties to deliver aircraft under contract to us on a timely basis, risk of breach of security of personal data, volatility of fuel costs, labor issues and costs, the ability to obtain regulatory approvals as needed, the effect of economic conditions on leisure travel, debt covenants and balances, the impact of government regulations on the airline industry, the ability to finance aircraft to be acquired, the ability to obtain necessary government approvals to implement the announced alliance with VivaAerobus and to otherwise prepare to offer international service, terrorist attacks, risks inherent to airlines, our competitive environment, our reliance on third parties who provide facilities or services to us, the impact of management changes and the possible loss of key personnel, economic and other conditions in markets in which we operate, the ability to successfully operate Sunseeker Resort at Charlotte Harbor, increases in maintenance costs and the availability of outside maintenance contractors to perform needed work on our aircraft on a timely basis and at acceptable rates, cyclical and seasonal fluctuations in our operating results and the perceived acceptability of our environmental, social, and governance efforts.
Any forward-looking statements are based on information available to us today and we undertake no obligation to publicly update any forward-looking statements, whether as a result of future events, new information or otherwise.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
There have been no material changes to our critical accounting estimates during the six months ended June 30, 2024. For information regarding our critical accounting policies and estimates, see disclosures in the Consolidated Financial Statements and accompanying notes contained in our 2023 Form 10-K, and in Note 1 of Notes to Consolidated Financial Statements (unaudited).

Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are subject to certain market risks, including commodity prices (specifically aircraft fuel). The adverse effects of changes in these markets could pose potential losses as discussed below. The sensitivity analysis provided does not consider the effects that such adverse changes may have on overall economic activity, nor does it consider additional actions we may take to mitigate our exposure to such changes. Actual results may differ.
Aircraft Fuel
Our results of operations can be significantly impacted by changes in the price and availability of aircraft fuel. Aircraft fuel expense for the six months ended June 30, 2024 represented 26.7 percent of our total operating expenses. Increases in fuel prices, or a shortage of supply, could have a material impact on our operations and operating results. Based on our fuel consumption for the six months ended June 30, 2024, a hypothetical ten percent increase in the average price per gallon of fuel would have increased fuel expense by approximately $34.6 million. We do not hedge fuel price risk.
Interest Rates
As of June 30, 2024, we had $434.9 million of variable-rate debt, including current maturities, and without reduction for $3.2 million in related costs. A hypothetical 100 basis point change in interest rates would have affected interest expense on variable rate debt by approximately $2.2 million for the six months ended June 30, 2024.
Item 4. Controls and Procedures
As of June 30, 2024, under the supervision and with the participation of our management, including our chief executive officer ("CEO") and chief financial officer (“CFO”), we evaluated the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the “Exchange Act”) as of the end of the period covered by this report. Based on that evaluation, management, including our CEO and CFO, has concluded that our disclosure controls and procedures are designed, and are effective, to give reasonable assurance that the information we are required to disclose is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to the Company’s management, including the CEO and the CFO, as appropriate to allow timely decisions regarding required disclosure.
Except as set forth below, there were no changes in our internal control over financial reporting that occurred during the quarter ending June 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
The Sunseeker Resort opened on December 15, 2023 and the Resort is currently in its first full year of operations. Management has implemented internal controls over financial reporting related to Resort activities and continues to evaluate those controls and procedures.
