We flew back from Mex just before Christmas. The AA lounge was ..... ok. The food offering wasn't great but we'd been out for lunch so we weren't starving and were planning to eat onboard (managed to snag some F seats). The barman is a little surly but he does make a very nice Margarita. It wasn't busy at all, and about 20 yards from the gate which was a plus. Not one of the best lounges, but then we haven't used that many so far.
