Hey all, I'm flying MSY-LHR on BA into T5 in a few days and was thinking about venturing over to T3 to use the AA Arrivals Lounge since I have a long layover (I should be eligible as an EXP/OWE in Y according to AA.com). Is the AA T3 lounge any better than the BA T5 lounge? Or will this be a pointless trip?
