Los Angeles International Airport (IATA: 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 70,622,212 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.The airport also was 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.
While LAX is the busiest airport in the Greater Los Angeles Area, 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, Great Lakes Airlines, and Virgin America. The airport also serves as a focus city for Southwest Airlines, Allegiant Air, Air New Zealand, Qantas, and Volaris. LAX is the only airport to serve as a hub for all three U.S. legacy airlines (American, Delta and United). LAX serves as either a hub or focus city for more airlines than any other airport in the United States. LAX, along with Miami International Airport are the only 2 US airports that are a hub/focus city for an airline that primarily serves a different country.
LAX is one of the few airports in North America with direct scheduled service to all six inhabited continents, the others being John F. Kennedy International Airport, George Bush Intercontinental Airport (starting in December 2015), and Toronto Pearson International Airport. Wikipedia
