Rewritten

In addition, there can be no assurance that the Company [removed: will] [added: would] be able to cost-effectively hedge against increases in fuel prices.

Rewritten

The Company's fuel hedging arrangements and the various potential impacts of hedge accounting on the Company's financial position, cash flows, and results of operations are discussed in more detail under "Management’s Discussion and Analysis of Financial Condition and Results of Operations," "Quantitative and Qualitative Disclosures About Market Risk," and in Note 1 and Note [removed: 11] [added: 10] to the Consolidated Financial Statements.

Rewritten

As discussed further under "Management’s Discussion and Analysis of Financial Condition and Results of Operations," the Company's unionized workforce makes up approximately [removed: 83] [added: 82] percent of its Employees and many have had pay scale increases as a result of contractual rate increases, which has put pressure on the Company's labor costs.

Rewritten

For instance, the cost of insurance premiums related to hail and wind damage has increased for certain facilities, and [removed: certain flood insurance is no longer available.]

Rewritten

[removed: In response,] [added: Additionally,] most major U.S. airlines [removed: now] offer expanded cabin segmentation fare products, such as "basic [removed: economy" and] [added: economy,"] "premium [removed: economy"] [added: economy," and "first class"] products.

Rewritten

Rewritten

The [added: Company’s transformational initiatives are discussed in more detail under “Business.” The] timely and effective execution of the Company's strategies is dependent upon, among other factors, (i) the Company's ability to balance its network schedule and capacity with the availability and location of its crew resources; (ii) the Company's ability to effectively balance its investment of incremental operating expenses and capital expenditures related to its strategies against the need to effectively control costs; (iii) the Company's ability to timely and effectively implement, transition, and maintain related information technology systems and infrastructure; (iv) [removed: as discussed below,] the Company’s ability to maintain satisfactory relations with its Employees or its Employees’ representatives; [removed: and] (v) the [added: Company’s ability to broaden its Customer base; and (vi) the] Company's dependence on third parties with respect to the execution of its strategic plans.

Rewritten

As discussed in more detail under [removed: "Business - Competition,"] [added: "Business—Competition,"] the airline industry is intensely competitive.

New in FY2024

Increases in insurance costs or reductions in insurance coverage may adversely impact the Company’s operations and financial results.

New in FY2024

certain flood insurance is no longer available.

New in FY2024

The Company has also announced plans for certain transformational initiatives, such as changing to an assigned seating model, offering premium seating with extra legroom, formalizing partnerships with international carriers to expand its network, offering Getaways by Southwest, introducing 24-hour operations, and reducing the turn times between flights.

New in FY2024

The Company’s commercial and operational initiatives are designed to meet evolving Customer preferences, increase revenue opportunities, mitigate cost pressures, and modernize processes.

New in FY2024

However, the Company cannot offer any assurances that these measures or any future initiatives will be successful in increasing revenues or offsetting costs.

New in FY2024

Additionally, the implementation of these initiatives may create logistical challenges that could harm the operational performance of the airline or result in decreased demand for air travel on Southwest.

New in FY2024

If the Company does not successfully execute its transformational initiatives or other strategic plans, or if actual results vary significantly from its expectations, the Company’s business, operating results, and financial condition may be adversely affected.

New in FY2024

The Company's low-cost position has been challenged by the removal of fare floors for certain routes by other carriers, leading to a lower fare offering across the industry, as well as “unbundled” service offerings by some carriers, which appeal to price-sensitive travelers through promotion to consumers of relatively low base fare options.

New in FY2024

The Company plans to move to an assigned seating model and will offer a premium economy fare product with extra legroom to meet Customer preferences and better compete with the major U.S. airlines.

New in FY2024

If the Company cannot adequately retain and attract Customers or differentiate its product offerings from those of its competitors, then its business, financial condition, and results of operations could be materially adversely affected.

New in FY2024

Many of the Company’s competitors participate in joint ventures and international alliances, providing for increased financial resources and improved profit margins.

New in FY2024

Many major U.S. airlines also offer longer-haul, international routes through extensive global networks.

New in FY2024

In order to compete with these activities and expand its transatlantic and transpacific service offerings, the Company began to enter into international partnerships in 2025.

New in FY2024

Failure to successfully implement and manage international partnerships could result in financial losses and reputational harm.

New in FY2024

The airline industry may also be impacted by mergers, acquisitions, heightened financial pressures, or bankruptcies.

New in FY2024

Further consolidation in the airline industry generally could result in the reduction of fares by other airlines, which could in turn affect the Company’s profitability in existing and new markets.

New in FY2024

If the Company cannot maintain its costs at a competitive level, then its business, financial condition, and results of operations could be materially adversely affected.

New in FY2024

The Company currently operates a higher percentage of the Boeing 737 aircraft than other air carriers in the industry, and therefore may encounter novel hazards, age-related maintenance issues, or airworthiness issues associated with 737 aircraft to a larger degree than other carriers.

New in FY2024

Although the Company has reached final labor agreements with its twelve unionized Employee groups, the next of which becomes amendable in October 2026, general wage inflation has resulted, and is expected to continue to result, in pressure on the Company's low-cost structure.

New in FY2024

Although the Company surpassed pre-pandemic staffing levels in 2023, Boeing aircraft delivery delays, network optimization efforts, and cost control initiatives required the Company to re-evaluate its hiring needs in 2024 and beyond and moderate staffing in line with demand.

New in FY2024

The operations of the Company’s third-party vendors and service providers could also be affected by the policies, procedures, and performance of their suppliers, and the Company may not have visibility into this multi-tiered supply chain.

New in FY2024

products, or otherwise fulfill their commitments to the Company, could materially adversely affect the Company’s operations.

New in FY2024

Moreover, any resulting economic dislocations could

New in FY2024

Any failure, disruption, or delay in implementation of the Company’s IT Systems could

New in FY2024

limit or even curtail its growth, delay strategic initiatives, increase its compliance costs, harm its reputation, or reduce its competitive advantage.

New in FY2024

The Company’s inability to timely or effectively implement, update, or integrate its IT Systems, could materially affect its business and/or could negatively impact the Company's results of operations and financial performance.

New in FY2024

The Company is expanding its use of AI and machine-learning to carry out elements of its business strategy.

New in FY2024

The implementation of AI technologies also presents significant operational, legal, and competitive risks to the Company.

New in FY2024

Although the Company believes it diligently evaluates, tests, and deploys a limited amount of AI-related technologies, the Company could face numerous AI-related challenges, such as cybersecurity vulnerabilities, algorithmic biases or errors, evolving regulatory requirements across jurisdictions, and potential competitive disadvantage if the Company’s competitors deploy AI technologies more quickly or more successfully.

New in FY2024

The complex and evolving legal landscape surrounding AI technologies, particularly regarding intellectual property rights and data privacy, creates additional compliance challenges and potential liability.

New in FY2024

For example, emerging regulations and state laws around AI may require companies that develop or deploy AI systems to establish formal governance structures and internal controls, including designated oversight personnel, documented risk assessment procedures, and regular compliance reviews of their AI systems.

Dropped from FY2023

If the MAX aircraft were to become unavailable for the Company's operations, or if the Company were to

Dropped from FY2023

- Developing and expanding data security and privacy requirements could increase the Company's operating costs, and any failure of the Company to maintain the security of certain Customer, Employee, and business-related information could result in disruption to operations and damage to the Company's reputation and could be costly to remediate.

Dropped from FY2023

For example, fuel prices can be impacted by political,

Dropped from FY2023

The airline industry could face potential fuel shortages in 2024 due to pipeline capacity constraints, resulting from the shifting of jet fuel allocations during the COVID-19 pandemic, as well as a national shortage of interstate trucking capacity.

Dropped from FY2023

The Company is working with aviation industry stakeholders to address these issues.

Dropped from FY2023

However, unless there is additional jet fuel distribution capacity, whether by pipeline and/or by truck, there could be temporary disruptions (e.g., flight cancellations or passenger caps) at one or more of the Company’s airports in 2024, especially during peak travel periods.

Dropped from FY2023

Additionally, as indicated under "Business - Employees," a significant number of Southwest's unionized Employees, including its Flight Attendants; Ramp, Operations, Provisioning, and Freight Agents; and Flight Simulator Technicians are in unions currently in negotiations for labor agreements, which could result in additional pressure on the Company's low-cost structure.

Dropped from FY2023

The Company's low-cost position has also been challenged by the growth of "Ultra-Low Cost Carriers" ("ULCCs"), which in some cases have surpassed the Company's cost advantage with larger aircraft, increased seat density, and lower wages.

Dropped from FY2023

ULCCs have further introduced "unbundled" service offerings, which appeal to price-sensitive travelers through promotion to consumers of an extremely low relative base fare for a seat, while separately charging for related services and products.

Dropped from FY2023

A basic economy product provides for a lower base fare to compete with a ULCC base fare, but may include significant additional restrictions on amenities such as seat assignments (including restrictions on group and family seating), order of boarding, checked baggage and use of overhead bin space, flight changes and refunds, and eligibility for upgrades.

Dropped from FY2023

A "premium economy" fare targets consumers willing to pay a premium for certain amenities that were previously included in the carriers' base fare (e.g., more favorable seating locations in the main cabin).

Dropped from FY2023

In response to competitive ULCC pricing, some carriers removed fare floors for certain routes, leading to a lower fare offering across the industry.

Dropped from FY2023

Additionally, three of the Company’s twelve unionized Employee groups are in unions currently in negotiations for labor agreements, which could result in additional pressure on the Company's low-cost structure.

Dropped from FY2023

The impact of the COVID-19 pandemic has heightened the Company’s exposure to its labor risks.

Dropped from FY2023

At the same time, competition for skilled personnel became fierce, which led to operational challenges in the first half of 2022.

Dropped from FY2023

In addition, the Company has been required to provide incentive pay and increase certain starting wage rates to address these challenges.

In addition, the Company’s systems may require modification to enable the Company to comply with changing regulatory requirements.

Dropped from FY2023

Modifications and refinements to the Company’s systems have been and are expected to continue to be expensive to implement and can divert management’s attention from other matters.

Dropped from FY2023

In addition, the Company’s operations could be adversely affected, or the Company could face imposition of regulatory penalties, if it were unable to timely or effectively modify its systems as necessary or appropriately balance the introduction of new capabilities with the management of existing systems.

Dropped from FY2023

Certain new technologies, such as the use of AI, present new and significant risks related to intellectual property, personal data, and confidentiality, among others.

Dropped from FY2023

The development of generative AI technologies is complex, and there are legal and practical challenges associated with achieving the desired level of accuracy, efficiency, and reliability.

Dropped from FY2023

The algorithms and models utilized in generative AI systems may have limitations, including biases, errors, or inability to handle certain data types or scenarios.

Dropped from FY2023

Furthermore, there is a risk of system failures, disruptions, or vulnerabilities that could compromise the confidentiality, integrity, or availability

Dropped from FY2023

of the generated content.

Dropped from FY2023

The legal landscape is also developing around generative AI technologies and generated content, and the Company's ability to use and commercialize generated content may be affected by legal developments related to intellectual property rights in generated content.

Dropped from FY2023

These limitations or failures could result in reputational damage, legal liabilities, or loss of Customer confidence.

Dropped from FY2023

There can be no assurance that the usage of AI will enhance the Company’s strategies or initiatives.

Dropped from FY2023

While the Company’s crew scheduling software worked as designed during this event, due to a number of factors, including unanticipated changes in the severity of the weather, the Company began implementing frequent close-in flight cancellations.

Dropped from FY2023

As the situation escalated and close-in flight cancellations grew, the volume of unanticipated changes were too great to efficiently address through the crew scheduling software, resulting in individual crew member assignment updates being delayed in a significant number of instances.

Dropped from FY2023

Without updated, accurate crew member data, the Company’s crew scheduling software could not reassign crew members to solve for flights with crew coverage issues.

Dropped from FY2023

As a result, during 2023 the Company enhanced its crew scheduling software to help the Company during events that could result in a large number of broken crew pairings.

Dropped from FY2023

Any future operational disruptions or delays could reduce the Company’s operating revenues and the attractiveness of its services, as well as increase the Company’s costs.

Dropped from FY2023

Developing and expanding data security and privacy requirements could increase the Company's operating costs, and any failure of the Company to maintain the security of certain Customer, Employee, and business-related information could result in disruption to operations and damage to the Company's reputation and could be costly to remediate.

Dropped from FY2023

Many of these laws and regulations are subject to change and reinterpretation, and could result in claims, changes to the Company’s business practices, monetary penalties, increased cost of operations, or other harm to the Company’s business.

Dropped from FY2023

In addition, it could be costly to remediate.

Dropped from FY2023

In addition, in response to these types of threats, there has been heightened legislative and regulatory focus on data privacy and security in the United States, European Union, and elsewhere.

Dropped from FY2023

The regulatory framework for data privacy and security worldwide is continuously evolving and developing and, as a result, the Company must monitor a growing and fast-evolving set of legal requirements and geopolitical risks in this area.

Dropped from FY2023

This regulatory environment is increasingly challenging and may present material obligations and risks to the Company's business, including significantly expanded compliance requirements, costs, and enforcement risks.

New in FY2024

The Company had a record full year 2024 revenue performance, producing operating revenues of $27.5 billion, due to continued demand strength and the benefits from the execution of tactical actions related to initiatives announced by the Company in 2024 designed to elevate the Customer Experience on its flights, improve financial performance, and drive Shareholder value.

New in FY2024

Additional drivers included record ancillary revenue and passengers carried.

New in FY2024

During 2024, the Company continued to return value to its Shareholders.

New in FY2024

The Company returned $680 million to Shareholders through $430 million in dividend payments and $250 million through an accelerated share repurchase program entered into by the Company with a third party financial institution in fourth quarter 2024.

New in FY2024

The Company subsequently received 6.8 million shares of common stock in October 2024, representing an estimated 80 percent of the shares to be purchased by the Company under the Fourth Quarter 2024 ASR Program, and an additional one million shares in January 2025 in final settlement of the Fourth Quarter 2024 ASR Program.

New in FY2024

The number of shares that the Company ultimately repurchased under the Fourth Quarter 2024 ASR Program was determined based generally on a discount to the volume-weighted average price per share of the Company's common stock during a

New in FY2024

calculation period completed in January 2025.

New in FY2024

See "Liquidity and Capital Resources" below for further information on the Company's 2024 share repurchases.

New in FY2024

The Company has $2.25 billion remaining under its September 2024 $2.5 billion share repurchase authorization.

New in FY2024

On December 5, 2024, the Company announced its intention to launch a $750 million accelerated share repurchase program in first quarter 2025.

New in FY2024

See Part II, Item 5 for further information on the Company's share repurchase authorizations.

New in FY2024

On a GAAP basis, the Company’s results for the year ended December 31, 2024, included a reversal of $116 million of breakage revenue recorded in prior years related to a portion of flight credits issued to Customers during 2022 and prior that have either been redeemed or are expected to be redeemed in future periods.

New in FY2024

The majority of these flight credits were issued during the COVID-19 pandemic as the Company was making significant changes to its flight schedules based on fluctuating demand.

New in FY2024

This adjustment was treated as a special item and excluded from the Company's presentation of non-GAAP results.

New in FY2024

Projections and targets do not reflect the potential impact of special items because the Company cannot reliably predict or estimate those items or expenses or their impact to its financial statements in future periods.

New in FY2024

Accordingly, the Company believes reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures for these projected results is not meaningful or available without unreasonable effort.

New in FY2024

(h) See Note Regarding Use of Non-GAAP Financial Measures for additional information on ROIC.

New in FY2024

(i) The Company estimates its full year 2025 effective tax rate to be in the range of 22 percent to 24 percent.

New in FY2024

The expected year-over-year improvement is driven primarily by a focus on capacity rationalization and the Company's continued focus on the execution of its tactical initiatives.

New in FY2024

The Company also anticipates continued strength in the demand environment.

New in FY2024

Year-over-year unit cost trends are expected to improve throughout the year as labor comparisons ease, efficiency initiatives generate modest capacity growth, and cost plan benefits are aggressively pursued.

New in FY2024

Based on its current plan, the Company expects to exit 2025 with year-over-year CASM-X growth in the low-single digits.

New in FY2024

Improving cost performance is a key focus.

New in FY2024

The Company is urgently working to accelerate and exceed the $500 million cost initiative announced at its 2024 Investor Day to help mitigate cost inflation by minimizing hiring, optimizing scheduling efficiency, capitalizing on supply chain opportunities, and aggressively improving corporate overhead.

New in FY2024

As part of the Company's ongoing modernization efforts, during 2024, the Company announced several new initiatives designed to elevate the Customer Experience on its flights, improve financial performance, and drive Shareholder value.

New in FY2024

As part of its ongoing focus on product evolution, the Company is moving forward with plans to assign seats, offer premium seating options, redesign the boarding model, and introduce redeye (i.e., overnight) flying.

New in FY2024

The Company has been known for its open seating model for more than 50 years, which was unique in the airline industry and has been popular with Southwest Customers for decades.

New in FY2024

Open seating served the Company well as a primarily short-haul carrier.

New in FY2024

The open seating design, combined with historically lower load factors, contributed to the efficiency of turning aircraft quickly.

Dropped from FY2023

The Company had record full year 2023 revenue performance, producing operating revenues of $26.1 billion, due to healthy leisure demand and continued yield strength combined with record ancillary revenue, loyalty program revenue, and passengers carried.

Dropped from FY2023

The Company’s 2022 results were somewhat impacted by the COVID-19 pandemic, as the Omicron variant of COVID-19 both impacted travel demand and created staffing challenges for the Company, particularly during January and February 2022.

Dropped from FY2023

However, strong travel demand, especially associated with leisure travel, accelerated during March 2022 and continued through 2023.

Dropped from FY2023

In 2023, the Company was able to focus on completing a comprehensive winter action plan, restoring its network and operational stability, reaching full utilization of its fleet, and delivering on significant new capabilities for its Customers.

Dropped from FY2023

Subsequent to Winter Storm Elliott, the Company was challenged to realign flight crews, flight schedules, and aircraft for a period of several days during this peak demand travel period.

Dropped from FY2023

For fourth quarter 2022, the Company estimated the financial impact of this disruption was approximately $800 million on a pre-tax basis.

Dropped from FY2023

A significant portion of this impact in fourth quarter 2022 was due to the loss of Operating revenue associated with the flight cancellations that was estimated to be approximately $410 million, and the remaining impact primarily related to a net increase of approximately $390 million in operating expenses, primarily due to travel expense reimbursements to Customers, the estimated value of Rapid Rewards points offered as a gesture of goodwill to Customers that were expected to be redeemed, and premium pay and additional compensation for Employees, which were partially offset by lower fuel and oil and profitsharing expenses.

Dropped from FY2023

On October 27, 2023, the Department of Transportation ("DOT") notified the Company that it determined the Company had failed to provide adequate customer service assistance, prompt flight status notifications, and proper and prompt refunds and that the assessment of a civil penalty was warranted.

Dropped from FY2023

During fourth quarter 2023, the Company accrued an expense of $107 million associated with a settlement reached with the DOT in December 2023 based on their investigation into the disruption, which includes a cash penalty and incorporates a future commitment for Southwest Customer care with a new Customer compensation policy.

Dropped from FY2023

An additional $33 million penalty was also assessed by the DOT, but was able to be credited against the substantial value the Company had already provided to its Customers impacted by the disruption, and therefore did not result in further impact to the Company's financial results for 2023.

Dropped from FY2023

To boost operational resiliency in key areas across the Company and to mitigate the risk of a recurrence, the Company developed a three-part tactical action plan focused on improving winter operations, accelerating

Dropped from FY2023

operational-related investments, and enhancing cross-team collaboration.

Dropped from FY2023

The Company's action plan was released in March 2023 and key winter operations steps were completed as of October 2023, as planned.

Dropped from FY2023

The expense related to the tentative agreement with Pilots combined with the charge related to the settlement with the DOT resulted in the Company reporting a net loss of $252 million on a GAAP basis for fourth quarter 2023.

Dropped from FY2023

Furthermore, on a GAAP and non-GAAP basis, the financial results for the year ended December 31, 2022 included a negative financial impact of approximately $800 million on a pre-tax basis in fourth quarter 2022 related to the December 2022 operational disruption and, on a GAAP basis, the financial results for the year ended December 31, 2022 included a $193 million pre-tax loss on extinguishment of debt primarily due to the repurchase of a portion of the Company's May 1, 2020 public offering of $2.3 billion aggregate principal amount of Convertible Senior notes (the "Convertible Notes").

The Company currently plans for approximately 79 Boeing 737 MAX ("MAX") aircraft deliveries and 49 aircraft retirements in 2024, including 45 Boeing 737-700s ("-700") and four Boeing 737-800s ("-800").

Dropped from FY2023

The delivery schedule for the 737-7 ("-7") is dependent on the Federal Aviation Administration ("FAA") issuing required certifications and approvals to The Boeing Company ("Boeing") and the Company.

Dropped from FY2023

The FAA will ultimately determine the timing of the -7 certification and entry into service, and Boeing may continue to experience supply chain challenges, so the Company offers no assurances that current estimations and timelines will be met.

Dropped from FY2023

This increase includes an approximate five point tailwind due to the negative revenue impact incurred in first quarter 2023 associated with the December 2022 operational disruption.

Dropped from FY2023

Sequentially, the performance represents a healthy improvement driven primarily by network optimization, market share contributions from the Company's Global Distribution System initiative, growth in the Rapid Rewards loyalty program, and continued strength in overall demand.

Dropped from FY2023

The network optimization is materially complete with the March 2024 schedule, at which point the Company expects a return to profitability.

Dropped from FY2023

Approximately two to three points of the increase are driven by higher 2024 market wage rate accruals for Employee workgroups with open agreements and for overall 2024 labor cost increases, including the wage rate increases and agreed-upon work rule changes associated with the recently ratified Pilot contract.

Dropped from FY2023

The majority of the remaining increase is driven by year-over-year pressure from maintenance expenses.

Dropped from FY2023

Furthermore, the Company currently expects similar cost pressures throughout the year, driving 2024 CASM-X to increase approximately 5.5 percent to 7 percent, year-over-year.

Dropped from FY2023

Specifically, the Company expects approximately four to five points of the increase to be driven by higher year-over-year labor costs, and the balance of the increase is driven primarily by higher year-over-year maintenance expenses.

Dropped from FY2023

Progressing through the year, the Company's focus will be on regaining efficiencies to counter inflationary cost pressures.

Dropped from FY2023

To this end, the Company plans to end the year with headcount in the range of flat to down on a year-over-year basis.

Dropped from FY2023

The Company's 2024 plan leverages a set of initiatives, which most importantly, includes better aligning the route network to new demand patterns.

Dropped from FY2023

The Company expects these initiatives to contribute roughly $1.5 billion in incremental year-over-year pre-tax profits.

Rewritten

The Company has found that financial derivative instruments in commodities, such as [removed: West Texas Intermediate ("WTI")] [added: WTI] crude oil, Brent crude oil, and refined products, such as heating oil and unleaded gasoline, can be useful in decreasing its exposure to jet fuel price volatility.

Rewritten

In addition, to add further protection, the Company [removed: may] [added: has in the past] periodically [removed: enter] [added: entered] into jet fuel derivatives for short-term timeframes.

Rewritten

As of December 31, [removed: 2023,] [added: 2024,] the Company had no outstanding interest rate swap agreements and therefore no cash collateral deposits provided or held.

Rewritten

Due to the significance of the Company’s [added: current] fuel hedging program and the [added: historical] emphasis that the Company [removed: places] [added: has placed] on utilizing fuel derivatives to reduce its fuel price risk, the Company has created a system of governance and management oversight and has put in place a number of internal controls designed so that procedures are properly followed and accountability is present at the appropriate levels.

New in FY2024

For example, historically, a portion of the fuel derivatives in the Company's hedge portfolio have been based on the market price of WTI crude oil.

New in FY2024

As mentioned above in "Critical Accounting Policies and Estimates", since the Company could no longer demonstrate that derivatives based on WTI crude oil prices would result in effective hedges on a prospective basis, the change in fair value of all of the Company's derivatives based in WTI have been recorded to Other (gains) losses during the second half of 2024.

New in FY2024

The Company currently has no WTI-based derivatives that settle beyond 2024.

New in FY2024

In recent years, jet fuel prices have been more closely correlated with changes in the price of Brent crude oil, and therefore the Company has attempted to mitigate some of this risk by entering into more fuel hedges based on Brent crude.

New in FY2024

Further, during 2024, the Company announced 24-hour operation capabilities with the introduction of redeye flights.

New in FY2024

Booking of redeye flying on initial routes became available in July 2024, with the first redeye flights scheduled on February 13, 2025, in five initial nonstop markets: Las Vegas to Baltimore and Orlando; Los Angeles to Baltimore and Nashville; and Phoenix to Baltimore.

New in FY2024

During 2024, the Company sought to restructure and better optimize its network to better match capacity to demand and adjust for post-pandemic Customer travel patterns by reducing short-haul trips, redistributing resources to longer-haul trips in more profitable markets, and reducing flying on weekdays and at off-peak times with lower travel demand.

New in FY2024

In response to market conditions, the Company ceased service at Cozumel, Mexico; Houston Bush Intercontinental; Syracuse; and Bellingham in 2024.

New in FY2024

Such investments include moving to a fully digital (i.e., paperless) process, improved communication tools for Employees, and better visual and real-time information to assist both Customers and Employees.

New in FY2024

These initiatives are designed to lower unit costs, as the Company is expected to be able to generate either the same number of available seat miles (“ASMs”) with fewer aircraft or produce more ASMs utilizing the same number of aircraft in its fleet.

New in FY2024

These efforts are underway and are scheduled to be fully implemented by November 2025.
