4 Terminals and different airlines fly from each one of them. Find out here which terminal your airline flies from.

How to get to/from Heathrow:

• Tube (London Underground)– You can access this airport through the Piccadilly Line (dark blue). This crosses the city all the way from SW to NE (link to map). It is one of the cheapest options to get to Heathrow but you’d have to allow plenty of time to get there. An average of 50 minutes from downtown is the minimum travelling time. (London Underground Tube map here)
  
• Heathrow Express train– This is the fastest way into central London. It takes you directly to Paddington in 15 minutes. Trains depart every 15 minutes and the basic single fare is £15.50 – though you can travel in 1st class or get a small discount if buying return.
