London Heathrow Airport or Heathrow (IATA: LHR, ICAO: EGLL) is the principal airport for London. The United Kingdom's
biggest airport, Heathrow is also Europe's busiest airport for passenger traffic, and handles more international passenger
traffic than any other airport in the world.
Heathrow Airport is located in Hayes, which is in the London Borough of Hillingdon, 15 miles (24 km) west of
Charing Cross in Central London. It has two parallel main runways running east-west and four terminals. The airport is the
largest airport serving Greater London.
Terminal 5 was officially dedicated by Queen Elizabeth II on 14 March 2008 and opened to passengers on 27 March 2008. Construction of a new Terminal 2
complex to replace the old terminal building and adjacent Queen's Building began in 2009 with the first phase expected to open in 2014. Terminals 3 and 4 underwent
major refurbishments between 2007 and 2009. In November 2007, a consultation process began for the building of a new third runway and a sixth terminal,
which was controversially approved on 15 January 2009 by UK Government ministers. The project was subsequently cancelled on 12 May 2010 by
the Cameron Government.
