Travel from Heathrow Airport
When traveling to Warwick University from London Heathrow Airport, a very convenient choice is to book a travel in one of National Express coaches. You can buy tickets online here. The service departs from the central bus station at Heathrow Airport, which is located near terminals 2 and 3, and easily reachable from any of these via underground pedestrian passages. Luggage allowance is up to two suitcases, each weighing 20 kg, plus a piece of hand luggage.
The coach takes a little more than two hours to get to Coventry Pool Meadow Bus Station. This is about the same time that takes to travel from Heathrow to London Euston and switch to a train to Coventry, but there are no switches with the coach, and fares are lower, specially if you buy tickets well in advance.
