Salt Lake City International Airport (SLC) — Salt Lake City, Utah
Salt Lake City International Airport (IATA: SLC) is Utah's primary commercial aviation gateway and one of the Western United States' most important hub airports. Delta Air Lines operates SLC as a major western hub with dozens of daily departures to cities across North America, Europe, and the Pacific Rim. Southwest Airlines also maintains a large operation at SLC. The airport sits at 4,227 feet MSL in the Salt Lake Valley west of downtown, making it one of the highest-elevation major commercial airports in the United States and a critical gateway for the ski industry, outdoor recreation economy, and business travel serving Utah's rapidly growing metropolitan area.
SLC underwent a transformative multi-billion dollar terminal redevelopment program, with the first new terminal opening in 2020 and the second phase completing in 2024, replacing the airport's outdated 1960s-era facilities with a modern, efficient complex capable of handling over 26 million passengers annually. The new terminal offers significantly improved passenger flow, expanded retail and dining, and state-of-the-art gate infrastructure. The airport is designated a large hub by the FAA and handles international flights to Canada, Mexico, Europe, and destinations in Asia.

SLC as Utah's Gateway to the World
Salt Lake City International Airport's transformation under its multi-billion dollar redevelopment program reflects Utah's emergence as one of America's fastest-growing states and most dynamic economies. The new terminal complex, designed by HOK Architecture, provides a facility that finally matches the aspirations of a city and state that have outgrown their mid-century aviation infrastructure. With the 2034 Winter Olympics awarded to Salt Lake City, the airport's continued expansion and enhancement takes on added urgency as the world focuses its attention on Utah's mountain communities.
For the Utah economy, SLC represents far more than a travel convenience. The airport's hub status enables Utah's technology sector, outdoor recreation industry, tourism economy, and life sciences cluster to maintain the national and international connectivity required to compete. Delta's transpacific routes from SLC give Utah companies direct access to Asian manufacturing and market partners without connecting through Los Angeles or San Francisco. The FAA Northwest Mountain Region and the Utah DOT Aeronautics Division coordinate closely with the Salt Lake City Department of Airports to manage an airspace environment that balances SLC's Class B operations with the extensive general aviation traffic that serves Utah's diverse communities.
