San Diego International Airport (IATA: SAN, ICAO: KSAN, FAA LID: SAN), formerly known as Lindbergh Field, is an international airport three miles (4.8 km) northwest of Downtown San Diego, California, United States. It is owned and operated by the San Diego County Regional Airport Authority. The airport covers 663 acres (268 ha) of land. While primarily serving domestic traffic, San Diego has nonstop international flights to destinations in Canada, Germany, Japan, Mexico, and the United Kingdom.
San Diego International Airport is the second busiest single-runway airport in the world.[a] The airport’s landing approach is well known for its close proximity to the skyscrapers of Downtown San Diego, and can sometimes prove difficult to pilots for the relatively short usable landing area, steep descent angle over the crest of Bankers Hill, and shifting wind currents just before landing. San Diego International operates in controlled airspace served by the Southern California TRACON, which is some of the busiest airspace in the world.
Prior to the development of the airport, the area was a delta river outlet for the San Diego River into the San Diego Bay, which was then re routed to terminate to the Pacific Ocean parallel to Mission Bay.
The airport is near the site of the Ryan Airlines factory, but it is not the same as Dutch Flats, the Ryan airstrip where Charles Lindbergh flight-tested the Spirit of St. Louis before his historic 1927 transatlantic flight. The site of Dutch Flats is on the other side of the Marine Corps Recruit Depot, in the Midway neighborhood, near the intersection of Midway and Barnett avenues.
