Just in case anyone would like to know, we have just flown with AA on STN - JFK - STN, we left on Thurs and came back yesterday. The flights were great, on time and landed an hour early coming home. The only downside was that there were no individual seat back TV's, but we did know about that before we booked. The STN - JFK flight was completely full, hopefully a sign of good things to come. The AA check in agent in JFK said that the Stansted flights are very frequently overbooked.
