Well at least that was one thing American Airlines did right for us. They changed the arrival time on our flight next summer to San Juan. It was going to get in an hour and a half latter than it was when we booked.
We had booked with miles for 3 of our tickets and when we booked we could not schedule "day before" flights because there were no FF miles seats left.
But their change of schedules would have made us arrive with no time to spare to get to the ship. They moved us to the day before flight without us having to use any more miles or pay extra. I thought that was nice of them.
