I struggle to understand, with as much influence as it must have, how BA seems to be served worse than other airlines at LHR.
As a very regular traveller, it always seems to be BA flights which have to park on remote stands with passengers enduring an often highly uncomfortable sardine-tin bus ride to/from the aircraft.
And BA baggage (LHR not LGW) seems to be the one that now regularly takes one hour or more to be delivered to the carousel. Does not seem to be a problem for VS, LH, BD, SQ and MH, among others.
Would love to believe T5 will be the answer to everyone's prayers, but somehow doubt that will be the case, for some considerable time at least. Apparently, there will not initially be enough stands to cope with the number of movements!
