Land was acquired to build a major airfield a half mile from the old airfield site. The airport was approved to serve as a staging field by the Air Corps Ferrying Command 21st Ferrying Group in November 1941. In March 1941, the War Department certified improvements to the existing airport in Palm Springs as essential to National Defense. PSP was built as a United States Army Air Corps emergency landing field in 1939 on land owned by the Agua Caliente Band of Cahuilla Indians due to its clear weather and its proximity to March Field and the Los Angeles area. The airport was named as number 3 in a 2011 list of 'America's Most Stress-Free Airports' by Smarter Travel.

The facility operates year-round, with most flights occurring in the fall, winter, and spring. The airport covers 940 acres (380 ha) and has two runways. Palm Springs International Airport ( IATA: PSP, ICAO: KPSP, FAA LID: PSP), formerly Palm Springs Municipal Airport, is an airport two miles (3 km) east of downtown Palm Springs, California, United States.
