Aviation industry overview covers SkyWest operations and airline coding

SkyWest Airlines operates as a contract carrier for several major airlines, including United Airlines, Delta Air Lines, American Airlines, and Alaska Airlines. Rather than flying under its own brand, SkyWest provides regional service to hundreds of destinations across North America, including the United States, Canada, and Mexico. The airline utilizes a hub-and-spoke model to transport passengers from smaller cities to major hubs such as Chicago, Denver, Los Angeles, and San Francisco.

In the broader aviation industry, airlines utilize standardized identifiers known as airline codes. Southwest Airlines, for example, uses the IATA code ‘WN’ for commercial purposes like ticketing and baggage handling, while the ICAO uses the three-character code ‘SWA’ for operational and air traffic control communications.
