SkyWest Airlines

SkyWest Airlines

In the vast and intricate web of the American airline industry, while the major carriers like Delta, United, American, and Alaska capture the headlines, the seamless functionality of air travel often relies on a critical, yet less recognized, player: the regional airline. Among these, SkyWest Airlines stands as an undisputed giant, a quiet force that has consistently connected countless smaller communities to the national and global air transport system for over five decades. From its humble beginnings in southern Utah to its current status as the largest regional airline in North America, SkyWest’s story is one of unwavering reliability, strategic partnerships, and an unparalleled commitment to operational excellence.

From Commuter Service to Regional Powerhouse: The Early Days (1972-1980s)

SkyWest Airlines was founded on March 2, 1972, in St. George, Utah, by local attorney J. Ralph Atkin. Atkin, along with four friends, initially formed Inter American Aviation, Inc., for personal flying. However, recognizing a need for local air service after the demise of Dixie Airline, they soon pivoted to commercial flights, changing the name to Sky West Airlines, a division of SkyWest Aviation Inc.

The airline’s first scheduled flight took place on June 19, 1972, connecting St. George to Cedar City and on to Salt Lake City, Utah, using a small, six-seat Piper Seneca aircraft. In its nascent years, SkyWest embodied the true spirit of commuter aviation, with pilots often doubling as ticket agents and baggage handlers. The early fleet also included Piper Cherokee and Cessna models for charters, including unusual ventures like providing flights for the Immigration and Naturalization Service.

By the mid-1970s, SkyWest received crucial support through a state grant, allowing it to survive and reorganize. A pivotal step came in 1977 when it signed its first interline agreement with American Airlines, enabling passengers to be ticketed through to their final destination with a single check-in. In 1978, SkyWest became one of the first commuter airlines in the nation to be certified as an air carrier, subject to federal regulations akin to major airlines.

The 1980s marked a period of significant growth. SkyWest acquired its first 19-seat Fairchild Swearingen Metroliner turboprops, a workhorse for regional routes. A major expansion occurred in 1984 when SkyWest acquired Sun Aire Lines, a larger regional carrier based in Palm Springs, California. This acquisition nearly tripled SkyWest’s passenger volume and significantly expanded its presence in the competitive Southern California market, setting the stage for major airline partnerships.

The Era of Partnerships: Fueling Mainline Networks (1986-2000s)

SkyWest’s trajectory truly soared with the dawn of the major airline code-share era. In 1986, SkyWest signed its first significant capacity purchase agreement (CPA) with Western Airlines, operating as Western Express. When Delta Air Lines acquired Western Airlines in 1987, SkyWest’s contract seamlessly transitioned, and it became a crucial Delta Connection carrier. This partnership, allowing SkyWest to feed passengers into Delta’s vast network, became a cornerstone of its business.

The 1990s saw SkyWest expand its partnerships and transition towards a jet-powered fleet. In 1997, it began operating as United Express out of United Airlines’ hubs in San Francisco (SFO), Los Angeles (LAX), and Denver (DEN), quickly becoming United’s largest regional operation. The introduction of the Bombardier CRJ200 regional jet in the late 1990s marked a major shift away from turboprops, providing faster and more comfortable service on regional routes. SkyWest was notably the launch customer for the CRJ200 and would eventually become its largest operator.

By the early 2000s, SkyWest was a dominant force in the regional airline sector, operating extensive networks for both Delta Connection and United Express. Its strategic growth allowed it to constantly modernize its fleet and optimize its operations.

Main Operating Bases: The Feeder Network’s Heart

SkyWest Airlines, unlike major airlines, does not operate its own passenger hubs. Instead, it operates from the hubs of its mainline partners, providing essential feeder services. Its vast network means it has numerous crew domiciles and maintenance locations strategically positioned across the country. These de facto “operating bases” include:

  • Salt Lake City (SLC): A historically significant domicile, particularly for its Delta Connection operations, reflecting its Utah roots.
  • Denver (DEN): A major base for both United Express and historically Delta Connection operations.
  • Chicago O’Hare (ORD): A crucial hub for United Express and American Eagle operations.
  • Houston (IAH): A key base for United Express.
  • Los Angeles (LAX) & San Francisco (SFO): Important West Coast bases for United Express and Alaska Airlines.
  • Seattle (SEA) & Portland (PDX): Primary bases for Alaska Airlines and Delta Connection flights.
  • Dallas/Fort Worth (DFW): A growing base for American Eagle operations.
  • Atlanta (ATL): A major domicile for Delta Connection flights.
  • Phoenix (PHX): Another significant hub in the Southwest.

These numerous bases allow SkyWest to efficiently dispatch its vast fleet and support its extensive daily operations across multiple partner networks.

The Fleet: An All-Jet Powerhouse

SkyWest’s fleet evolution has been a story of continuous modernization and a strategic shift from turboprops to an all-jet fleet since 2015. Today, it operates one of the largest and most modern regional jet fleets in the world.

  • Early Propellers: Piper Seneca, Navajo Chieftain, Cessna 207/206, Fairchild Swearingen Metroliner, Embraer EMB 120 Brasilia. These were essential for its early commuter routes.
  • Bombardier CRJ Family: This series became the backbone of SkyWest’s operations for decades.
    • CRJ200 (50-seat): Launched by SkyWest, these were the workhorses for its early jet expansion and smaller market connections.
    • CRJ700 (65-70 seat): Introduced in the early 2000s for higher-demand regional routes.
    • CRJ900 (70-76 seat): The largest of the CRJ family, offering increased capacity. SkyWest notably took delivery of the very last CRJ ever built, a CRJ900, cementing its place in aviation history.
    • CRJ550 (50-seat, premium configuration): A unique variant, reconfigured from CRJ700s, offering more first class and premium economy seats, primarily for United Express and Delta Connection.
  • Embraer E-Jet Family (E175): Starting in 2014, SkyWest introduced the highly popular Embraer E175 jets. These aircraft, often configured with 76 seats (including First Class and Economy Plus), offer a mainline-like passenger experience and have become increasingly favored by mainline carriers due to their efficiency and comfort.

As of March 31, 2025, SkyWest’s impressive fleet comprises approximately 488 aircraft, making it the largest regional fleet in the United States. This includes a mix of CRJ200s, CRJ550s, CRJ700s, CRJ900s, and a significant number of E175s (over 260 of them). The airline continues to take delivery of new E175s, further solidifying its modern, efficient fleet.

Route Network: The Unseen Connector

SkyWest Airlines operates an expansive route network that mirrors the demand of its mainline partners. It serves as a vital connector, linking smaller and medium-sized communities across North America to the major hubs of United Airlines (as United Express), Delta Air Lines (as Delta Connection), American Airlines (as American Eagle), and Alaska Airlines (as Alaska Airlines operated by SkyWest Airlines).1

  • Domestic U.S.: SkyWest serves an astonishing 262 destinations across 45 states and Washington D.C. This includes feeder flights from smaller airports (e.g., in Idaho, Montana, Arkansas, Iowa) to major hubs like Denver, Salt Lake City, Chicago, or Houston. It also operates high-frequency routes between larger regional cities and mainline hubs.
  • International: SkyWest extends its reach beyond the U.S. borders, serving destinations in 7 Canadian Provinces and 11 Mexican Cities for its mainline partners. These typically include routes to popular tourist destinations or border cities from U.S. hubs.

In 2024, SkyWest operated over 42 million passengers across approximately 200,000 departures in the first quarter of 2025 alone. Its sheer operational scale is a testament to its critical role in the North American air travel system.

Business Model, Challenges, and Future Outlook

SkyWest’s success is largely attributed to its Capacity Purchase Agreements (CPAs) with major airlines. Under a CPA, the mainline partner (e.g., United, Delta) pays SkyWest fixed rates for operating flights, based on completed flights, block hours, and aircraft under contract. The mainline carrier assumes the risk of selling tickets and managing demand, while SkyWest focuses on providing the operational capacity. This model offers stable revenue streams, allowing SkyWest to manage its costs and invest in fleet modernization.

Despite this robust business model, SkyWest, like the broader regional airline industry, has faced significant challenges:

  • Pilot Shortage: In the late 2010s and early 2020s, a severe pilot shortage impacted the entire industry. Major airlines hired aggressively from regional carriers, leaving many regionals, including SkyWest, with insufficient crews to fly all their contracted hours. This led to grounded aircraft and reduced profitability. SkyWest has proactively responded with aggressive pilot recruitment, training programs (like the Pilot Pathway Program), and competitive compensation packages.
  • Evolving Mainline Strategies: Mainline carriers constantly adjust their regional flying needs, impacting contracts and fleet requirements. SkyWest must remain agile to secure and adapt to these changes.
  • Operational Costs: Rising fuel and maintenance costs remain a constant pressure, even under CPAs where some costs are passed through.

SkyWest Inc., the holding company for SkyWest Airlines, also briefly owned ExpressJet Airlines (and its subsidiary Atlantic Southeast Airlines) after acquiring ExpressJet Holdings Inc. in 2010. However, after attempts to consolidate, SkyWest Inc. ultimately spun off ExpressJet (which by then included ASA) in 2018 to focus on its core, highly successful SkyWest Airlines operation.

Looking ahead, SkyWest continues to strengthen its relationships with its major partners, expand its Embraer E175 fleet, and navigate the pilot supply challenges. Its focus on operational excellence, safety, and a disciplined business approach positions it to remain a dominant force in regional aviation.

The Enduring Role of an Unsung Giant

SkyWest Airlines is a remarkable success story in the highly competitive airline industry. It is the invisible force that enables millions of Americans to access the global air travel network from their local communities. With its sprawling network, massive modern fleet, and unwavering commitment to reliability, SkyWest Airlines truly is the unsung backbone of U.S. regional aviation, constantly soaring to new heights while connecting the nation, one regional flight at a time.
