This was originally posted by someone else in Jan. and is exactly my problem. I have 90min. to get from terminal 3(AA) to terminal 2 (BA). We will have no bags to collect only carry-on and are arriving at 6:55am. Can someone walk me through the route.

I would call AA and BA and ask them the best way to deal with the situation. You may want to search Heathrow and look at the layout and see if there is a shuttle bus etc.

Inter-terminal transfers are explained in some detail on the Heathrow Airport website, http://www.baa.co.uk/main/airports/heathrow/. In short, to get from T3 to T2, you take the shuttle bus to the Flight Connection Centre, go through customs and security, and walk to your departure gate. They estimate 60 minutes from time of landing to T2 departure gate.<BR><BR>I have done the T1 to T3 connexion. The route is fairly well signed and there was a lot of walking.<BR><BR>You may want to, however, check your departure terminal. It is my understanding that BA only uses T4 (international), T1 (domestic) and T3 (Miami).

When I did this last summer BA actually handed out little maps before we landed. Don't fret about it -- 90 min is PLENTY of time. Follow the signs and just ask if you're confused. Everyone speaks English, you know, and they really are quite a friendly and helpful people.

I called AA last night..thankyou for the responses. AA said I would not have to go thru customs until I reached Switzerland and terminal 2 &amp; 3 are connected by a tunnel (approx. 15 min walk).
