As you can see, Heathrow has four main terminals on the map. Terminal 1 is the most northern terminal, and terminals 2, 3 and 4 are spread around it connected by the airport train (shown by the black dotted line on the map. If you’re parking short term, you can choose absolutely any of the bays marked on the map, as the airport train will take you wherever you need to be and you therefore don’t need to worry about being at the right terminal when you’re picking someone up or dropped them off.

If you’re boarding at terminal 1 (the most common terminal to board from), you will find gates 1 to 12 slightly to your left as you go in, gates 74 to 90 more directly to your left, gates 15 to 34 almost directly ahead and gates 35 to 56 further on your right. There are no gates for boarding from terminal 2 as it closed for modernisation and will re-open in 2014. For terminal 3, you enter from the north-east and you will find gates 1 to 10 on your direct left, gates 11 to 24 straight ahead and gates 25 to 33 directly to your left; much easier to navigate than terminal 1! Terminal 4 is entered from the south-east side and gates 1 to 21 are visible from the moment you walk in, for gates 22 to 25 you have to follow an intricate set of corridors to the left to reach your desired gate.
