just spent a happy few minutes on that Twitter account - this individual really does sound like a prize plum; BA should just explain to him that no, sorry, GGL isn't important enough to allow Arrivals Lounge access on short-haul since (shock horror) there are a few thousand GGLs out there and (even more shock horror) at least a hundred or more will be flying into T5 short-haul any given day - hence it's a capacity issue
I mean, honestly.
The other tweets are complaining about the shower gel in T5 lounges being diluted (eh?) and also berating Virgin Trains for allowing their staff to run the First Class service too quickly....as if Virgin Trains was meant to be a real "first class" thing. Oh dear.
