query: How old is London Gatwick Airport?
passage: Gatwick Airport
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]

The airport is accessible from a motorway spur road at junction 9A of the M23, which links to the main M23 motorway 1 mile (1.6km) east at junction 9. The M23 connects with London's orbital motorway, the M25, 9 miles (14km) north; this provides access to much of Greater London, the South East and beyond, and the M23 is the main route for traffic to the airport. Gatwick is also accessible from the A23, which serves Horley and Redhill to the north and Crawley and Brighton to the south. The A217 provides access northwards to the town of Reigate. The airport has long- and short-stay car parks at the airport and off-site, although these are often full in summer. Local restrictions limit parking at (and near) Gatwick.
