London Heathrow terminal guideAirport Guide
Heathrow is one of Europe's busiest hubs, handling around 84.5 million passengers a year (2025) about 24 km from central London. It now operates four terminals — 2, 3, 4 and 5 (Terminal 1 has closed), and each terminal is closely tied to an airline alliance, so which airline you fly largely decides which building you use.
The four terminals in use
| Code | Name | Gates | Main users |
|---|---|---|---|
| T2 | Terminal 2 (The Queen's Terminal) | A1–A20 | Star Alliance carriers |
| T3 | Terminal 3 | B1–B16 | oneworld carriers |
| T4 | Terminal 4 | C1–C14 | SkyTeam and some others |
| T5 | Terminal 5 | Concourses D / E / F | British Airways |
Two practical consequences follow:
- A connection within the same alliance usually stays in one building, which makes for the smoothest transfer.
- A cross-alliance connection will most likely change terminals, so allow for it.
Note the gate lettering: T2 uses A, T3 uses B, T4 uses C, and T5 uses the D, E and F concourses. The letter itself is a clue to the terminal.
Changing terminals and connecting
Heathrow's terminals are linked by a free airside/landside transfer, but a terminal change plus a second security check is a real cost in time. Our advice:
- Once ticketed, confirm the terminal for both flights — do not rely on the airline name alone.
- For a cross-terminal connection, build the transfer and security time into your buffer; a same-terminal connection is far more forgiving.
- Inside T5 the D, E and F concourses are some distance apart — if your gate is in F, set off early.
Routes and flights
- Routes — in 2025 the airport connected around 80-plus countries and about 230 destinations, one of the most connected hubs in Europe; long-haul points include New York, Los Angeles, Beijing, Shanghai, Tokyo, Singapore, Sydney and Johannesburg.
- Flights — 84.5 million passengers in 2025 (+0.7% year on year), with 477,894 aircraft movements and an average of 1,309 a day.
- Aircraft — main base is British Airways (T5 exclusively), followed by Virgin Atlantic (T3) and other oneworld and Star Alliance carriers; short-haul uses the A320 family, while intercontinental uses the A380, 747, 777, 787 and A350 widebodies.
Getting into central London
- Heathrow Express — about 15 minutes direct to Paddington, and the fastest option.
- Piccadilly line — direct to many central districts at a fraction of the price, but stops all the way in.
- Coach — National Express long-distance services, useful if you are heading straight to another city.
- Taxi — the black cab, available on demand, and the most expensive.
Practical tips
- It is 24 km into the centre. Choosing between "fast" (Heathrow Express) and "cheap" (Piccadilly line) mostly comes down to luggage and arrival time.
- Paddington connects to the Underground and mainline rail, so for destinations beyond west London the Express is usually quicker than staying on the Tube.
- If your itinerary allows, pick flights that arrive and depart from the same terminal and you remove the terminal change entirely.
