As has been said before most airports have bussing to some stands,the busier airports get the more remote stands are used, Liverpool doesn`t have any contact stands at all neither does Luton and Leeds have very few if any so I cannot really see much of a problem most of the time
It might not be much of a problem but the general preference is to arrive at the 'front door' particularly from a large a/c or long haul. Generally the more contact gates the better but MAG has other ideas with a gradual removal and/or poor maintenance standards of the existing, and little net gain following installation of new infrastructure at Terminal 2.
