....oh. You're back.
Thinking of me dear? So happy you wasted text, time and effort on me x
American are in T3 because they do offer connections with AY (via T1) and BA and to that effect, thousands of passengers have to have additional biometrics taken as they move from A to B to facilitate the trickle of intl-intl transfer passengers. On paper it sounds good, the reality is.....leas than ideal if you just want to get on a domestic flight!
They were much better off in T2. It's partly up to American which one of JFK/ORD/PHL to promote really, might they be better (he said repeating himself) offering two destinations from T2 across a A332/B772 and a B757/B767?
