What is the airport code for Palm Springs, California?

The airport code for Palm Springs, California, is PSP. This code is associated with Palm Springs International Airport, which serves the city and the surrounding Coachella Valley region. Airport codes are typically three-letter designations used to identify specific airports internationally, and each airport has a unique code for ease of identification in travel itineraries and aviation communications.
