Trying to gauge UG chances on PHL-DUB on Sep 20 (AA722). 12 of the 20 J seats are empty, MCE is pretty full. Me (EXP) and PPro companion. I've never flown out of PHL. Is this route, or routes out of PHL generally, usually elite heavy? Does J typically sell out? I know routes out of CLT to Europe tend to be tough.
