Hi. We'll be returning a rental car, probably from Avis, the morning we fly out of Heathrow back to the U.S. For convenience and timing purposes, like to know whether their drop-off location is right at the airport; and if not, whether they have a shuttle from the car rental facility to the airport. Not to sound too grumpy but these inscrutable questions stumped the Avis help desk. Thanks - Alan in Virginia
They are in the same complex with many other rental car returns. Easy to follow signs to car return once you make it to Heathrow. There is a small shuttle bus to the main airport area. I can't remember which terminal it goes to, but it was fairly easy for us to make it to the Heathrow Express to London from there. It serves several rental car services and comes every 15-20 minutes, even very late in the evening. You'll have no problem.
