SKYWEST INC (SKYW) Business

ITEM 1. BUSINESS

General

Through SkyWest Airlines, our primary operating entity, we offer scheduled passenger service to destinations in the United States, Canada and Mexico. Substantially all of our flights are operated as United Express, Delta Connection, American Eagle or Alaska Airlines flights under code-share agreements with United, Delta, American or Alaska, respectively. Code-share agreements are commercial agreements between airlines that, among other things, allow one airline to use another airline’s flight designator codes on its flights. As of December 31, 2025, we offered approximately 2,260 daily departures, of which approximately 940 were United Express flights, 680 were Delta Connection flights, 420 were American Eagle flights and 210 were Alaska Airlines flights.

We generally provide regional flying to our major airline partners under long-term, fixed-fee, code-share agreements. Under these fixed-fee agreements (commonly referred to as “capacity purchase agreements”), our major airline partners generally pay us fixed rates for operating the aircraft primarily based on the number of completed flights, flight time and the number of aircraft under contract. The major airline partners either directly pay for or reimburse us for specified direct operating expenses, including fuel expenses. Our operations are conducted principally at airports that support our major airline partners’ route networks, including Chicago (O’Hare), Dallas, Denver, Detroit, Houston, Los Angeles, Minneapolis, Phoenix, Salt Lake City, San Francisco and Seattle.

We conduct our code-share operations with our major airline partners pursuant to various code-share agreements described under the heading “Code-Share Agreements” below.

Fleet

SkyWest has been flying since 1972. During our long operating history, we have developed an industry-leading reputation for providing quality regional airline service. As of December 31, 2025, our fleet consisted of aircraft manufactured by Embraer S.A. (“Embraer”), including the E175 regional jet aircraft (“E175”), and aircraft manufactured by MHI RJ Aviation ULC, formerly known as Bombardier Aerospace (“Bombardier”), including the Canadair CRJ900 regional jet aircraft (“CRJ900”), the Canadair CRJ700 regional jet aircraft (“CRJ700”), including a 50-seat configuration of the CRJ700 aircraft, commonly referred to as a “CRJ550” and the Canadair CRJ200 regional jet aircraft (“CRJ200”). As of December 31, 2025, we had 637 total aircraft in our fleet, including 487 aircraft in scheduled service or under contract pursuant to our code-share agreements, summarized as follows:

Bombardier and Embraer are the primary manufacturers of regional jets operated in the United States and offer many of the amenities of larger commercial jet aircraft, including flight attendant service, a stand-up cabin, overhead and

under seat storage, lavatories and in-flight snack and beverage service. The Bombardier CRJ900, CRJ700 and CRJ550 aircraft and the Embraer E175 aircraft we operate under our code-share agreements are configured with a first-class seating section. The Bombardier CRJ200 aircraft we operate under our code-share agreements are configured in a 50-seat configuration with single-class seating. The speed of Bombardier and Embraer regional jets is comparable to larger aircraft operated by major airlines, and they have a range of approximately 1,600 miles and 2,100 miles, respectively. As of December 31, 2025, our fleet seat configuration by aircraft type is summarized as follows:

SkyWest Leasing

SkyWest Leasing is a reportable segment that includes revenue associated with our financing of new aircraft with debt under our capacity purchase agreements, currently consisting of our E175 aircraft, and the depreciation and interest expense of our E175 aircraft. The SkyWest Leasing segment additionally includes the revenue and expense from leasing aircraft and engines to third parties. The SkyWest Leasing segment’s total assets and capital expenditures include the acquired E175 aircraft and aircraft and engines leased to third parties.

As of December 31, 2025, SkyWest Leasing leased 40 CRJ700 aircraft, five CRJ900 aircraft and regional jet aircraft engines to third parties.

SkyWest Charter (SWC)

In 2022, we formed a new subsidiary, SWC, which began operations in 2023. SWC offers on-demand charter service using CRJ200 aircraft in a 30-seat configuration. As of December 31, 2025, SWC had 11 aircraft available for on-demand charter service. In September 2025, the U.S. Department of Transportation (the “DOT”) granted SWC authorization to operate as a commuter air carrier. We are evaluating opportunities to use SWC as a commuter air carrier.

Competition and Economic Conditions

The airline industry is highly competitive. We compete principally with other regional airlines. Our operations extend throughout most major geographic markets in the United States. Our competition includes, therefore, nearly every other domestic regional airline. Our primary competitors include CommuteAir, Inc.; Endeavor Air, Inc. (“Endeavor”) (owned by Delta); Envoy Air Inc. (“Envoy”), PSA Airlines, Inc. (“PSA”) and Piedmont Airlines (“Piedmont”) (Envoy, PSA and Piedmont are owned by American); Horizon Air Industries, Inc. (“Horizon”) (owned by Alaska Air Group, Inc.); GoJet Airlines, LLC (“GoJet”); and Republic Airways Holdings Inc. (“Republic”). Major airlines typically award code-share flying agreements to regional airlines based primarily upon the following criteria: ability to fly contracted schedules, availability of labor resources, including pilots, low operating cost, financial resources, geographical infrastructure, overall customer service levels relating to on-time arrival and flight completion percentages and the overall image of the regional airline. Additionally, each major airline may be limited in the number and type of regional aircraft it may use in its network due to agreements the major airline has with its own labor groups, commonly referred to in the industry as “scope limitations.” Given our major airline partners’ scope limitations, we currently do not operate a regional aircraft configured with more than 76 seats.

The principal competitive factors for regional airline code-share agreements include labor resources, code-share agreement terms, reliable flight operations, operating cost structure, ability to finance new aircraft, certification to operate certain aircraft types and geographical infrastructure supporting markets and routes served.

Our operations represent the largest regional airline operations in the United States. However, regional carriers owned by major airlines may have access to greater resources than we do through their parent companies.

Generally, the airline industry is sensitive to changes in general economic conditions. Economic downturns, combined with competitive pressures, have contributed to a number of reorganizations, bankruptcies, liquidations and business combinations among major and regional carriers. The effect of economic downturns may be somewhat mitigated by our predominantly contract-based flying agreements. If, however, any of our major airline partners

experience a prolonged decline in the number of passengers or are negatively affected by low ticket prices or high fuel prices, they may seek rate reductions in future code-share agreements, or materially reduce scheduled flights in order to reduce their costs. In addition, adverse weather conditions can impact our ability to complete scheduled flights and can have a negative impact on our operations and financial condition. Also, major airline scope limitations may restrict certain fleet-type growth opportunities for the regional carriers. Additionally, attrition of our pilots or other workgroups may reduce our flying schedules and have a negative impact on our operations and financial condition.

Impact of Regional Airline Captain Availability on Production

As passenger demand in the airline industry recovered from the COVID-19 pandemic in 2020, the number of regional airline captains and first officers hired by major airlines and low-cost carriers significantly increased. As a result, we experienced a high level of captain and first officer attrition during 2022 and 2023, which constrained our capacity to operate our major airline partners’ requested flight schedules in full. During 2024, captain attrition began to ease and, by the end of 2025, we were operating full flight schedules requested by our major airline partners. Sequential fluctuations in the number of completed departures and completed block hours from 2023 to 2025 were primarily driven by available captains.

Capacity and flight schedule impact. We completed the following number of flights and related block hours in 2025, 2024 and 2023:

Liquidity

At December 31, 2025, we had $782.5 million in total available liquidity, consisting of $706.9 million in cash, cash equivalents and marketable securities, and $75.6 million available for borrowing under our line of credit.

Industry Overview

Majors, Low-Cost Carriers and Regional Airlines

The airline industry in the United States has traditionally been comprised of several major airlines, including Alaska, American, Delta and United. The major airlines offer scheduled flights to most major U.S. cities, numerous smaller U.S. cities, and cities throughout the world through a hub-and-spoke network.

Low-cost carriers, such as Southwest Airlines Co. (“Southwest”), JetBlue Airways Corporation (“JetBlue”), Spirit Airlines, Inc. (“Spirit”), Allegiant Travel Company (“Allegiant”), Frontier Group Holdings, Inc. (“Frontier”) and Breeze Aviation Group, Inc. (“Breeze”) generally have lower cost structures than major airlines, which permits them to offer flights to and from many of the same markets as the major airlines, but at lower prices. Low-cost carriers typically operate using a point-to-point network strategy, rather than a hub-and-spoke network.

Regional airlines, including SkyWest, typically operate smaller aircraft on shorter routes than major and low-cost carriers. Several regional airlines, including Endeavor, Envoy, Horizon, Piedmont and PSA, are wholly-owned subsidiaries of major airlines.

Regional airlines generally do not try to establish an independent route system and compete with the major airlines. Rather, regional airlines typically enter into agreements with one or more major airlines, pursuant to which the regional airline agrees to use its smaller, lower-cost aircraft to carry passengers booked and ticketed by the major airline between a hub of the major airline and a smaller outlying city. In exchange for such services, the major airline pays the regional airline either fixed fees to operate the flight, termed “capacity purchase agreement,” or “flying contract,” or the regional airline receives a percentage of applicable passenger ticket revenues on designated flights operated by the regional airline, termed “prorate agreement” as described in more detail below.

Code-Share Agreements

Regional airlines generally enter into code-share agreements with major airlines, pursuant to which the regional airline is authorized to use the major airline’s two-letter flight designator codes to identify the regional airline’s flights and fares in the central reservation systems, to paint its aircraft with the colors and/or logos of the major airline and to market and advertise its status as a carrier for the major airline. Code-share agreements also generally obligate the major airline to provide services such as reservations, ticketing, ground support and gate access to the regional airline, and the major airline often coordinates marketing, advertising and other promotional efforts. In exchange, the regional airline provides a designated number of low-capacity (usually between 50 and 76 seats) flights between larger airports served by the major airline and surrounding cities, usually in lower-volume markets. The financial arrangements between the regional airlines and their code-share partners usually involve either capacity purchase agreements or prorate agreements as explained below:

We have code-share agreements with United, Delta, American and Alaska. During the year ended December 31, 2025, approximately 84% of our flying agreements revenue related to capacity purchase agreement flights, where United, Delta, American and Alaska controlled scheduling, ticketing, pricing, and seat inventories. The remainder of our flying agreements revenue during the year ended December 31, 2025, related to prorate flights for United, Delta or American, where we controlled scheduling, pricing and seat inventories on certain prorate routes, and shared passenger fares with United, Delta or American according to prorate formulas and SWC on-demand charter flights. The routes placed under our prorate agreements typically include flight service between one of our partners’ hub cities and a city not served under our capacity purchase agreements.

Under our capacity purchase agreements, our major airline partners compensate us for our costs of owning the aircraft on a monthly basis. The aircraft compensation structure varies by agreement but is intended to cover either our aircraft principal and interest debt service costs or our aircraft depreciation and interest expense while the aircraft is under contract. The number of aircraft under our capacity purchase agreements and our prorate agreements as of December 31, 2025 is reflected in the summary below. The following summaries of our code-share agreements with our major airline partners do not purport to be complete and are qualified in their entirety by reference to the applicable agreement.

Table of Contents

In addition to the aircraft operating under the respective agreements outlined above, we have agreed with our major airline partners to place additional aircraft under capacity purchase agreements as summarized below. We are coordinating with the aircraft manufacturer and our major airline partners regarding the timing of upcoming fleet deliveries. The anticipated deliveries and in-service timing referenced below are subject to change.

Table of Contents

In January 2026, we extended the scheduled contract expirations on 40 E175 aircraft with United and 13 E175 aircraft with Delta. The termination dates in the table above reflect the January 2026 extensions.

United Express Agreements

We and United are parties to two United Express capacity purchase agreements: a United Express agreement to operate certain CRJ700 aircraft, and a United Express agreement to operate E175 aircraft, CRJ550 aircraft and CRJ200 aircraft (collectively, the “United Express Agreements”).

The United Express Agreements have a latest scheduled termination date of 2033. The United Express Agreements are subject to early termination in various circumstances including:

Delta Connection Agreement

We and Delta are parties to a Delta Connection capacity purchase agreement (the “Delta Connection Agreement”), pursuant to which we provide contract flight services for Delta.

The Delta Connection Agreement has a latest scheduled termination date of 2034. The Delta Connection Agreement is subject to early termination in various circumstances including:

American Agreement

We and American are parties to a capacity purchase agreement (the “American Agreement”) for the operation of E175 and CRJ700 aircraft. The American Agreement has a latest scheduled termination date of 2032 and is subject to early termination in various circumstances including:

Alaska Agreement

We and Alaska are parties to a capacity purchase agreement (the “Alaska Agreement”) for the operation of E175 aircraft. The Alaska Agreement has a latest scheduled termination date of 2034 and is subject to early termination in various circumstances including:

Training and Aircraft Maintenance

We provide substantially all training to our crew members and maintenance personnel at our training facilities. Our employees perform routine airframe and engine maintenance along with periodic inspections of equipment at our maintenance facilities. We also use third-party vendors for certain airframe and engine maintenance work.

Fuel

Our capacity purchase agreements with United, Delta, American and Alaska require the respective major airline partner to pay for fuel costs, either directly to the fuel vendor or to reimburse us for the fuel costs we incur under those agreements, thereby reducing our exposure to fuel price fluctuations. Under our prorate agreements with United, Delta and American, we are responsible for the costs to operate the flights, including fuel costs, and therefore we are exposed to fuel price fluctuations for flights operated under our prorate agreements. During the year ended December 31, 2025, our major airline partners purchased the majority of the fuel for our aircraft flying under their respective capacity purchase agreements directly from their fuel vendors or, when applicable, reimbursed us for the fuel costs we incurred under the capacity purchase agreements. Historically, we have not experienced sustained material problems with the availability of fuel and believe we will be able to obtain fuel in quantities sufficient to meet our existing and anticipated future requirements at competitive prices. We typically purchase fuel from third-party suppliers for our prorate agreements. A substantial increase in the price of jet fuel for flights we operate under our prorate agreements may have a material adverse effect on our financial results if we are unable to recover such cost increases through higher passenger fares. A substantial, prolonged shortage of fuel supply in the future, could have a material adverse effect on our business, financial condition, results of operations or liquidity.

Human Capital Resources

Employee Profile

As of December 31, 2025, we employed 15,775 total employees, consisting of 5,354 pilots, 4,831 flight attendants, 2,028 airport operations personnel, 1,728 maintenance technicians, 967 other maintenance personnel, 199 dispatchers and 668 operational support and administrative personnel. Our total employees at December 31, 2025, included 1,957 part-time employees. As of December 31, 2025, all our employees are employed by SkyWest Airlines or to a limited extent, by SWC. Certain SkyWest Airlines employees also provide administrative support to the SkyWest Leasing segment. Approximately 89.6% of these employees were represented by in-house labor associations that have entered into collective bargaining agreements regarding employee compensation and work rules. None of these employees are currently represented by an outside union. Outside union organizing efforts among our employees do occur from time to time and may continue in the future. If unionization efforts are successful, we may be subjected to increased risks of work interruption or stoppage; and/or we may be limited in our ability to communicate with our employees, which would negatively impact our culture and working relationship with our employees. Additionally, an outside union may limit our ability to increase employee wages to market rates in a timely manner which could result in low employee job satisfaction and increased employee attrition. SkyWest Airlines has never experienced a work stoppage due to a strike or other labor dispute, and we consider our relationships with our employees to be good.

Table of Contents

Our relations with labor are governed by the Railway Labor Act (the “RLA”), the federal law governing labor relations between air carriers and their employees. Under the RLA, a collective bargaining agreement between an airline and a labor representative does not expire, but instead becomes amendable as of a stated date. If either party wishes to modify the terms of any such agreement, it must notify the other party in the manner prescribed by the RLA and/or described in the agreement. After receipt of such notice, the parties must meet for direct negotiations, and if no agreement is reached, either party may request the National Mediation Board (“NMB”) to initiate a process including mediation, arbitration, and a potential “cooling off” period that must be followed before either party may engage in “self-help.” “Self-help” includes, among other things, a strike by the representative or the imposition of proposed changes to the collective bargaining agreement by the airline. If the NMB believes that self-help has the risk “substantially to interrupt interstate commerce to a degree such as to deprive any section of the country of essential transportation service,” it may recommend that the President establish a Presidential Emergency Board (“PEB”). The PEB would hear testimony and make a recommendation regarding how to resolve the outstanding issues.

We respect all employees’ legal rights, including the rights to free association and collective bargaining. This includes the right to decide whether to be represented by a union. Under the RLA, employees have the right to decide whether they wish to be represented by a union. They also have the right to reject union representation.

Culture

At SkyWest our people are our most valued assets, and the success of our business is dependent on having a collaborative, engaged and effective workforce. We respect every individual's quality of life and are committed to promoting integrity and trust in all we do. We strive to be the partner of choice and employer of choice.

Health & Safety

Safety is the primary focus and foundation of our culture with our first guiding principle being Health and Safety First. We expect our employees to think, plan, communicate and act appropriately to prevent injury, illness or harm to themselves, fellow employees, passengers and aircraft. SkyWest’s Safety Management System (SMS) integrates an intentional safety culture into every work group and every employee process from new hire through retirement, focusing on industry-best practices in safety competencies and behaviors. Safety training is required for every SkyWest employee annually, regardless of position.

SkyWest’s SMS is designed to identify, track, and help mitigate potential safety risks before an incident or accident occurs. Employees are encouraged to participate in our voluntary programs to report potential safety concerns or violations to reduce safety risk, including, but not limited to our Aviation Safety Action Program and Safety Concern Report.

Attracting, Developing and Retaining Talent

Recruitment Strategies. We strive to be the employer of choice for aviation professionals pursuing a career in the regional airline industry and we continually update our recruiting strategies to attract quality aviation professionals. We adapt our recruitment efforts based on the supply of eligible aviation professionals and our outlook for anticipated future flight schedules. Our recruiting focus generally targets key aviation technical roles, especially pilots and mechanics. We seek qualified individuals through publishing positions on both internal and external career websites, supporting professional development leads, investment in targeted advertising, social media outreach, employee referrals and relationships with community-based organizations and educational institutions. Through various interview and related programs with our major airline partners,

11

Table of Contents

including United’s Aviate program, our pilots have carrier pathway opportunities with our major airline partners.

School Partnerships and Development. We maintain relationships with numerous flight schools and educational institutions across the country that are focused on developing the next generation of aviation professionals. We have also developed relationships with numerous aviation mechanic schools. We typically recruit pilots and maintenance technicians that have completed required coursework from an accredited flight or maintenance school, respectively, and have obtained other applicable certifications. We also provide other programs to enhance our recruiting efforts towards individuals who are in process of completing their training, including a Pilot Pathway Program and an Aviation Maintenance Technician (AMT) Pathway Program.

Ongoing Training and Retention. SkyWest invests in retaining its professionals by providing a range of talent development opportunities, including mandatory compliance training, new hire training and general professional development, as well as engaging in the training of leaders through leadership development courses. Our training programs include full-motion flight simulators for pilots, on-the-job training for technicians, and cabin trainers for flight attendants. We also reinforce our guiding principles, including but not limited to, health and safety, personal and corporate integrity, excellent service and quality, and respect and teamwork through our training and development programs, as well as through our employee appreciation and recognition programs.

Total Rewards

SkyWest Airlines operates in a customer-focused, team-based environment and provides opportunities for dedicated individuals to develop their career while receiving competitive compensation, benefits and rewards. Our employees receive several compensation benefits, including but not limited to:

Employee Reporting

Our Code of Conduct contains general guidelines for conducting business in an ethical manner. We are committed to a working environment that is safe and supports open and honest communication. We have established a reporting system for any SkyWest employee to report a violation of Company policy including harassment, discrimination, drug and alcohol use, questionable financial practice, or a breach involving safety or security. A general grievance may also be filed even if an employee has already utilized their chain of command or chooses to remain anonymous. Our Code of Conduct also forbids retaliation against any employee who, in good faith, reports a suspected

12

Table of Contents

violation of law or policy. Reports can be filed with an independent service provider using a toll-free ethics and grievance hotline or by using an online reporting system accessible through SkyWest’s intranet.

Government Regulation

All interstate air carriers, including SkyWest, are subject to regulation by the DOT, the U.S. Federal Aviation Administration (the “FAA”) and other governmental agencies. Regulations promulgated by the DOT primarily relate to economic aspects of air service. The FAA requires operating, airworthiness and other certificates; approval of personnel who may engage in flight, maintenance or operating activities; record-keeping procedures in accordance with FAA requirements; and FAA approval of flight training and retraining programs. Generally, governmental agencies enforce their regulations through, among other methods, certifications, which are necessary for the continued operations of SkyWest, and proceedings, which can result in civil or criminal penalties or revocation of operating authority. The FAA can also issue maintenance directives and other mandatory orders relating to, among other things, grounding of aircraft, inspection of aircraft, installation of new safety-related items and the mandatory removal and replacement of aircraft parts.

We believe SkyWest complies, in all material respects, with FAA regulations and holds all operating and airworthiness certificates and licenses which are necessary to conduct our operations. We maintain current certifications and otherwise comply with the laws, rules and regulations to which we are subject. Our flight operations, maintenance programs, recordkeeping and training programs are conducted under FAA approved procedures. All air carriers operating in the United States are required to comply with federal laws and regulations pertaining to noise abatement and engine emissions. All such air carriers are also subject to certain provisions of the Federal Communications Act of 1934, as amended, because of their extensive use of radio and other communication facilities. SkyWest is also subject to certain federal and state laws relating to protection of the environment, labor relations and equal employment opportunity. We believe SkyWest complies, in all material respects, with these laws and regulations.

Environmental Matters

We are subject to various federal, state, local and foreign laws and regulations relating to environmental protection matters. These laws and regulations govern such matters as environmental reporting, storage and disposal of materials and chemicals and aircraft noise. We are, and expect in the future to be, involved in various environmental matters and conditions at, or related to, our properties. We are not currently subject to any environmental cleanup orders or actions imposed by regulatory authorities. We are not aware of any active material environmental investigations related to our assets or properties.

As the largest regional airline in the United States, we remain committed to working with our major airline partners to lower our environmental footprint while continuing to offer the best service to our customers and the communities we serve. Our largest source of emissions and environmental impact comes from utilizing jet fuel on flights operated under our code-share agreements with our major airline partners. Under our capacity purchase agreements, our major airline partners purchase the aircraft fuel we consume, select the aircraft type we operate, and set flight schedules, all of which are variables which impact fuel consumption efficiencies. During 2025, we produced approximately 6.3 million metric tons of CO2e from fuel burned, using industry emissions factors, on flights we operated under our code-share agreements. We are largely dependent on direction from our major airline partners regarding long-term fuel saving and carbon reducing initiatives such as engine innovations reducing fuel consumption, use of sustainable alternative fuels, carbon sequestration programs, air traffic flow routing efficiencies, and similar initiatives. Each of our major airline partners may pursue alternative strategies and goals to reduce carbon emissions on flights we operate under our code-share agreements that may impact the rate at which we are able to reduce our carbon emissions, if at all. We anticipate our major airline partners will take responsibility for carbon emissions incurred on our contract flights.

Our board of directors has oversight of our environment-related performance. Through software and training, we heavily monitor and manage our fuel trends and fuel consumption which leads to better fuel management and reductions in emissions. When possible, we conserve fuel burned by utilizing single engine taxi procedures, improving the efficiency of aircraft routing, using performance-based navigation procedures to reduce track miles, and using ground power when parked at the gate. Additionally, we collaborate with aircraft and engine manufacturers and our major airline partners regarding innovations and emerging technologies that could improve fuel efficiencies and minimize environmental impact. We are also collaborating with our major airline partners and fuel providers regarding long-term

13

Table of Contents

opportunities to use sustainable aviation fuel in the future. We are evaluating opportunities to increase the number of electric powered ground equipment, including tugs and pushbacks used at airports where we provide ramp services. We participate with our major airline partners in recycling programs, and we have implemented recycling initiatives in our facilities to reduce the amount of paper, plastic and other recyclables going to landfills. We have worked aggressively to reduce our reliance on paper manuals, further eliminating unnecessary waste while increasing efficiencies.

We have entered into a strategic arrangement with Eve Holding, Inc. (“Eve”, formerly EVE UAM, LLC, an Embraer company) to develop a network of deployment for Eve UAM’s electric vertical takeoff and landing (“eVTOL”) aircraft. Subject to an agreement of key commercial terms, this arrangement includes the option for SkyWest to purchase up to 100 eVTOL aircraft.

Safety and Security

We are committed to the safety and security of our passengers and employees. We have taken many steps, both voluntarily and as mandated by governmental authorities, to increase the safety and security of our operations. Some of the safety and security measures we have taken with our major airline partners include: aircraft security and surveillance, aircraft cleaning procedures, positive bag matching procedures, enhanced passenger and baggage screening and search procedures and securing of cockpit doors. We are committed to complying with future safety and security requirements.

Insurance

We maintain insurance policies we believe are of types customary in the industry and in amounts we believe are adequate to protect against material loss. These policies principally provide coverage for public liability, passenger liability, baggage and cargo liability, property damage, including coverage for loss or damage to our flight equipment, and workers’ compensation insurance, and other coverages.

Seasonality

Our results of operations for any interim period are not necessarily indicative of those for the entire year, in part because the airline industry is subject to seasonal fluctuations and changes in general economic conditions. Our operations are somewhat favorably affected by leisure travel on our prorate routes, historically contributing to increased travel in the summer months, and are unfavorably affected by decreased business travel during the months from November through January and by inclement weather which can result in cancelled flights, principally during the winter months. Additionally, a significant portion of our capacity purchase agreements are based on completing flights and we typically have more scheduled flights during the summer months. We generally experience a significantly higher number of weather cancellations during the winter months, which negatively impacts our revenue during such months.
