title: Gatwick Airport
context: Gatwick opened as an aerodrome in the late 1920s; it has been in use for commercial flights since 1933. The airport has two terminals, the North Terminal and the South Terminal, which cover areas of 98,000m2 (117,000sqyd) and 160,000m2 (190,000sqyd) respectively.[8] It operates as a single-runway airport, using a main runway with a length of 3,316m (10,879ft). A secondary runway is available but, due to its proximity to the main runway, can only be used if that is out of use. In 2018, 46.1million passengers passed through the airport, a 1.1% increase compared with 2017.[9] As of 2019, Gatwick is the second busiest airport in the world to only operate one runway (after Chhatrapati Shivaji Maharaj International Airport) with a passenger use of 46 million in 2018.[10]
