It is also known as Lindbergh Field
San Diego International Airport (IATA: SAN, ICAO: KSAN, FAA LID: SAN) is the primary international airport serving San Diego and its surrounding metropolitan area in California. It is a relatively small airport with a single runway, which is the busiest in the United States and the third busiest in the world. The airport covers 663 acres of land and is the third busiest in California in terms of passenger traffic.
The airport is also known as Lindbergh Field. This name was inspired by Charles Lindbergh, the first pilot to fly solo across the Atlantic in his plane, the Spirit of St. Louis, which was built in San Diego by Ryan Aircraft. Lindbergh also flight-tested the Spirit of St. Louis at the nearby Dutch Flats Airport before his historic 1927 transatlantic flight. Excited by his achievement and proud that the plane was made in their city, San Diegans passed a bond issue in 1928 for the construction of a two-runway municipal airport, which they dedicated to Lindbergh, naming it San Diego Municipal Airport – Lindbergh Field.
However, in 2003, the airport's name was changed from Lindbergh Field to San Diego International Airport. This decision was made due to Lindbergh's well-documented racism, which did not align with the values of a multicultural and multi-ethnic San Diego. Lindbergh's beliefs included support for Hitler and the Nazis, as well as eugenics and race hatred directed at the peoples of the Pacific Rim.
