In-Depth Information
Heathrow has five terminals, numbered T-1 through T-5. Each terminal is served by
different airlines and alliances; for example, T-5 is exclusively for British Air and Iberia
Air flights, while T-1 serves mostly Star Alliance flights, such as United and Lufthansa.
Screens posted throughout the airport identify which terminal each airline uses; this in-
formation should also be printed on your ticket or boarding pass.
To navigate, read signs and ask questions. You can walk between T-1, T-2, and T-3.
From this central hub (called “Heathrow Central”), T-4 and T-5 split off in opposite dir-
ections (and are not walkable). To travel between the T-1/T-2/T-3 cluster and either T-4 or
T-5, you can take a shuttle bus (free, serves all terminals), or the Tube (requires a ticket,
serves all terminals). You can also connect T-1/T-2/T-3 and T-5 by Heathrow Express train
(free, every 15-20 minutes); transfer by free spur train from Heathrow Central (T-1/T-2/
T-3) to connect T-4.
