Heathrow Airport, located 22km west of central London, is the busiest airport in the United Kingdom and the third busiest in the world.
London Heathrow services more international passengers than any other airport in the world and nearly 70 million travellers a year pass through its terminals, flying to 170 destinations worldwide.
Heathrow is owned and operated by BAA Limited and has five terminals. Terminal 5 was opened by Queen Elizabeth II in 2008 and is the newest terminal in the airport, although Terminal 2 is currently undergoing major reconstruction. Once open, the new Terminal 2 will be similar in size to Terminal 5, which spans more than 360,000 square metres over two concourses.
Heathrow's terminals are connected by buses and the London Underground tube. A wide range of facilities are available in each terminal, including a variety of shops, bars and restaurants as well as post offices, showers and dedicated worship areas.
