I am wondering if, when T5 opens, the stands at the second satellite which is not built yet (2012 I believe, possibly in time for the Olympics) will be used as a whole series of bus gates from the main T5 building. Can't see how BA can fit all their operations in otherwise. Bus delays are one of the current bugbears for BA at Heathrow so they will have to come up with some radical plan for how they are handled.
