After the Second World War ended, plans for the airport’s expansion gathered momentum, with commercial operations starting in 1946. American Airlines, TWA, United, Western and Pan Am were the first airlines to move into the airport, which was renamed Los Angeles International Airport (LAX being its code) in 1949. One of its most famous features was added in 1961 – the futuristic Theme building, seen just off-centre in this image from 2022. Today, LAX is one of the world's busiest airports, with nine interconnected terminals.
