Terminal 2
The Queen's Terminal, used by Star Alliance airlines, some SkyTeam and unaligned airlines, and UK domestic and Irish flights.
London Heathrow Airport (LHR) is the main international airport for London and the United Kingdom, and in 2025 the busiest airport in Europe. It sits in the London Borough of Hillingdon, about 14 miles west of central London.
British Airways has its main hub here and flies from Terminal 5, with some flights from Terminal 3. Virgin Atlantic, the other oneworld airlines and Delta use Terminal 3; Star Alliance airlines and UK domestic and Irish flights use Terminal 2; and most SkyTeam and unaligned airlines, plus Qatar Airways, use Terminal 4. Between them they fly to almost every continent.
The airport has four passenger terminals, numbered 2 to 5; there is no longer a Terminal 1. Terminals 2 and 3 sit together in the central area, within walking distance of each other, while Terminals 4 and 5 are on the south and west sides of the airfield and are reached by train or bus.
From the airport, most travelers head into central London, to the West End, the City and Canary Wharf, or out to Windsor, Reading, Oxford and the Thames Valley. The Heathrow Express, the Elizabeth line and the Piccadilly line all run into London.
