I was wandering around Terminal C once with some extra time on my hands, before BA had even announced its MSY-LHR service, and I noticed a door marked "International Lounge," or something like that. It was locked and looked dark inside, and I never can recalling having seen it before, let alone in operation. But if you look at this map you can see it adjacent to Gate C1. I'm assuming BA departs from Terminal C. Perhaps this is the lounge that they're using (although note that a search of lounge locations on BA.com does not list this one).
