Heathrow Airport is a major international airport in west London, England. Heathrow is the busiest airport in the United Kingdom, busiest airport in Europe by passenger traffic, and third busiest airport in the world by total passenger traffic. In 2014, it handled a record 73.4 million passengers, a 1.4 percent increase from 2013.
Heathrow lies 12 nautical miles (22 km; 14 mi) west of Central London, and has two parallel east–west runways along with four operational terminals on a site that covers 12.14 square kilometres (4.69 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 the Spanish Ferrovial Group that includes Caisse de dépôt et placement du Québec and Government of Singapore Investment Corporation. 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. The commission shortlisted two options for expanding Heathrow in its interim report in 2013, along with a third option for expanding Gatwick Airport. The final report, published on 1 July 2015, backed a third runway at Heathrow.
