Heathrow Airport, originally called London Airport until 1966 and now known as London Heathrow (IATA: LHR, ICAO: EGLL), is a major international airport in London, England. Heathrow is the second busiest airport in the world by international passenger traffic, the third busiest airport in Europe by passenger traffic but only the twenty second busiest airport in the world by total passenger traffic, the sole UK entry in the top 50. It is one of six international airports serving the London region. In 2019, it handled a record 80.8 million passengers, a 0.9% increase from 2018 as well as 475,861 aircraft movements, a decrease of 1,743 from 2018. The airport facility is owned and operated by Heathrow Airport Holdings.
Heathrow lies 14 miles (23 km) west of Central London, and has two parallel east–west runways along with four operational passenger terminals, and one cargo terminal, on a site that covers 12.27 square kilometres (4.74 sq mi). The airport is the primary hub for British Airways and the primary operating base for Virgin Atlantic.
In September 2012, the Government of the United Kingdom established the Airports Commission, an independent commission chaired by Sir Howard Davies to examine various options for increasing capacity at UK airports. In July 2015, the commission backed a third runway at Heathrow, which the government approved in October 2016. However, the England and Wales Court of Appeal rejected this plan for a third runway at Heathrow, on the basis that the government failed to consider climate change and the environmental impact of aviation. On 16 December 2020, the U.K. Supreme Court lifted the ban on the third runway expansion, allowing the construction plan to go ahead.
Heathrow is 14 mi (23 km) west of central London, on a parcel of land that is designated part of the Metropolitan Green Belt. It is located 3 mi (4.8 km) west of the town of Hounslow, 3 miles south of Hayes, and 3 miles north-east of Staines-upon-Thames.
The airport is surrounded by the villages of Sipson, Harlington, Harmondsworth, and Longford to the north and the neighbourhoods of Cranford and Hatton to the east. To the south lie Feltham, Bedfont and Stanwell while to the west Heathrow is separated from Wraysbury, Horton and Windsor in Berkshire by the M25 motorway. Heathrow falls entirely within the boundaries of the London Borough of Hillingdon, and under the Twickenham postcode area, with the postcode TW6. The airport is located within the Hayes and Harlington parliamentary constituency.
As the airport is located west of London and as its runways run east–west, an airliner's landing approach is usually directly over the conurbation of London when the wind is from the west, which is most of the time.
The airport forms part of a travel to work area with Slough, the west part of Greater London, and the north part of Surrey.
