San Diego International Airport (IATA: SAN, ICAO: KSAN) formerly known as Lindbergh Field, is an international airport 4.8 km northwest of Downtown San Diego, California, United States. It is owned and operated by the San Diego County Regional Airport Authority. San Diego International covers 268 ha of land.
In 2015, traffic at San Diego International exceeded 20 million passengers, serving more than 500 scheduled operations carrying about 50,000 passengers each day. While primarily serving domestic traffic, San Diego has nonstop international flights to Canada, Germany, Japan, Mexico, Switzerland, and the United Kingdom.
San Diego is the largest metropolitan area in the United States that is not an airline hub or secondary hub; however, San Diego is a focus city for Alaska Airlines and Southwest Airlines. The top five carriers in San Diego during 2015, by seat capacity, were Southwest Airlines (42.7%), American Airlines (14.0%), United Airlines (11.2%), Alaska Airlines (10.1%), and Delta Air Lines (9.9%).
San Diego International is the busiest single runway airport in the United States and third-busiest single runway in the world, behind Mumbai and London Gatwick. Due to the airport's short usable-runway, close proximity to the skyscrapers of Downtown San Diego, and steep landing approach as a result of the nearby Peninsular Ranges, SAN has been called "the busiest, most difficult single runway in the world." SAN operates in controlled airspace served by the Southern California TRACON, which is some of the busiest airspace in the world.
