Los Angeles International Airport (LAX) is the world's fifth busiest passenger airport and ranks sixth in air cargo tonnage handled, and its popularity shows no sign of decreasing.
Originally known as Mines Field, the LAX site has been used as a general aviation field since 1928. During World War II, it was used for military flights. Commercial airline service started in December 1946. The present terminal complex was constructed in 1961. In the early 1980s, LAX added domestic and international terminals and a second-level roadway.
In 2004 more than 60 million people traveled through LAX. A commerce leader, its air cargo system handled more than two million tons of goods. LAX handled about 70 percent of the passengers, 75 percent of the air cargo, and 95 percent of the international passengers and cargo traffic in the five-county Southern California region.
