There is a very friendly American lady who works for BA who got negative feedback from a Brit who appeared to be a VIP or something. Sounded like he said he wanted to complain further about this lounge to other contacts of his at BA. She told me to look out for her and she generally lets GGL in. She knows the AA folks don't. Apparently, it's "an ongoing discussion". Sounds like "officially", GGL were never meant to be let in on regular domestic routes (so the website was "wrong"), but should be let in on long-haul and transcontinental (so the website is wrong now as well, since it only says long-haul). Still very much a YMMV situation. Looks like the BA folks are usually in from about 3 pm.

Anyway, bored of the menu here, so will head over to Soho in a moment and check out the buffet.
