Los Angeles International Airport (IATA: LAX, ICAO: KLAX, FAA LID: LAX) is the primary airport serving the Greater Los Angeles Area, the second-most populated metropolitan area in the United States. It is most often referred to by its IATA airport code LAX, with the letters pronounced individually. LAX is located in southwestern Los Angeles along the Pacific coast in the neighborhood of Westchester, 16 miles (26 km) from Downtown Los Angeles. It is owned and operated by Los Angeles World Airports, an agency of the Los Angeles city government formerly known as the Department of Airports.
In 2014, LAX handled an estimated 70.7 million passengers, far exceeding a previous record of 67.3 million travelers set in 2000. The airport holds the claim for "the world's busiest origin and destination (O & D) airport" in 2011, meaning it had the most non-connecting passengers, and the third busiest in the world by aircraft movements. It is also the only airport to rank among the top five U.S. airports for both passenger and cargo traffic.
LAX is the busiest airport in the Greater Los Angeles Area; however, other airports including Bob Hope Airport, John Wayne Airport, Long Beach Airport, and LA/Ontario International Airport also serve the region. It is also notable for being one of few U.S. airports with four parallel runways.
LAX serves as a hub for American Airlines, Delta Air Lines, United Airlines, Alaska Airlines, Horizon Air, and Great Lakes Airlines. The airport also serves as a focus city for Southwest Airlines, Virgin America, Allegiant Air, Air New Zealand, Qantas, and Volaris. LAX is the only airport to serve as a hub for all three legacy airlines (American, Delta and United).
