About SLC

Delta's hub for the US Mountain West, completely rebuilt with a new terminal that opened in 2020. It is one of the most reliable airports in America thanks to favourable weather and parallel runways. The airport is a key gateway to Utah's ski resorts and national parks.

Salt Lake City's airport began in 1911 as a cinder-covered landing strip on marshy ground known as Basque Flats, west of the young city. Renamed Woodward Field in 1920 after a local airmail pilot, it became a key stop on the pioneering transcontinental airmail route.

The city purchased and expanded it, renaming it Salt Lake City Municipal Airport in 1930. Western Air Lines made it an early operating base. Decades of steady growth brought the International title in 1968 as jets connected Utah to both coasts.

The modern era arrived when Delta Air Lines absorbed Western in 1987 and kept Salt Lake City as a hub, prizing its reliable weather and strategic position between Denver and the West Coast. By the 2010s the aging split-terminal complex was bursting. The airport undertook the first entirely new large hub airport built in the United States in the twenty-first century.

The New SLC opened its first phase in September 2020, a single sweeping terminal with the monumental art installation The Canyon in its plaza. The remaining concourse phases were completed in 2024. Today SLC is one of Delta's principal western hubs, with nonstop flights to Europe.

How SLC operates today

Salt Lake City operates four runways, including three long north-south parallels beside the Great Salt Lake wetlands, feeding the consolidated new terminal and its two linear concourses connected by an underground tunnel. Delta commands the large majority of flights, running efficient connecting banks that link mountain-west cities with the coasts and transatlantic services to hubs like Paris and Amsterdam.

The airfield's altitude of about 4,200 feet and hot summer days factor into performance planning. Winter inversions and lake-effect snow test the airport's well-drilled deicing teams. SkyWest, Delta's largest regional partner, also bases significant operations here.
