Heathrow Airport (also known as London Heathrow) (IATA: LHR, ICAO: EGLL) is a major international airport in London, United Kingdom. Heathrow is the second busiest airport in the world by international passenger traffic (surpassed by Dubai International in 2014), as well as the busiest airport in Europe by passenger traffic, and the seventh busiest airport in the world by total passenger traffic. In 2017, it handled a record 78.0 million passengers, a 3.1% increase from 2016.
Heathrow lies 14 miles (23 km) west of Central London, and has two parallel east–west runways along with four operational terminals on a site that covers 12.27 square kilometres (4.74 sq mi). The airport is owned and operated by Heathrow Airport Holdings, which itself is owned by FGP TopCo Limited, an international consortium led by Ferrovial that also includes Qatar Holding LLC, Caisse de dépôt et placement du Québec, GIC Private Limited, Alinda Capital Partners, China Investment Corporation and Universities Superannuation Scheme (USS). London Heathrow is the primary hub for British Airways and the primary operating base for Virgin Atlantic.
In September 2012, the UK government 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
