Thanks for the responses. Thankfully, there is one other flight after ours to the island. Worst case is we miss the flight and have to charter a plane for that evening or the next morning. The flight from DFW-SJU has pretty poor on time ratings too..
I was just baffled by the use of the OLD 757- I have flown AA 757s from DFW-OGG before but this was basically international business class minus PTV's. I believe "old" first class on these flights will be exactly the same as old domestic first class... isn't this correct?
