What is the airport code for the major airport in Salt Lake City?

The airport code for the major airport in Salt Lake City is SLC. This code is derived from the city's name and aligns with the standard three-letter airport codes used internationally, which are based on IATA (International Air Transport Association) designations. Each major airport typically has a unique identifier, making it easier for travelers and airlines to reference specific locations.

SLC represents Salt Lake City International Airport, which is a key hub for numerous airlines and serves domestic and international flights. The airport's code is commonly recognized and used by travelers and in flight scheduling or ticketing, reinforcing SLC as the correct choice.
