I must admit that on a visit to the AA arrivals lounge in T3 LHR, I was asked if I were Gold / AA Platinum and did, probably a little bit sarcastically, respond that I was in fact GGL, perhaps CK (muttering under my breath that this could be in the same ballpark should AA have any consistency from the CK/GGL thread).
Unsurprisingly, the girl had zero idea of what GGL was. Then again, in her defence, neither does BA 99.9999% of the time.
Everything has been quite civilised for me. Still looking for the right opportunity to flash my card at some interloper(s) but with exception of LHR free-for-all C-Gates a lot of the time, everyone queues nicely.
Even on AA, where the boarding process seems to have around 3 secs between each of groups 1, 2, 3 and 4 being called, no-one seems to be pushing forward.
