I am booked on a flight from JFK to Dallas Fort Worth, and then from Dallas Forth Worth on to Mazatlan. When I booked it, the connection time was 75 minutes, but now it is 54 minutes and they moved my seat to 34 D. I don't think I have a chance of making this flight and there is not another AA flight that day. It says international flights start boarding 45 minutes before. Do I have any hope??
