Booked a flight on AA a while back from Grand Cayman to Bozeman. The original booking had a 2:45 window from the arrival from GCM in MIA to the next flight out on the way to BZN. I was comfortable with the window of time as same airline in and out and no checked bags. Just received notice from AA changing flight times that reduces the window/lay over to just an 1:45. The arrival time in MIA is in the morning on Friday. Anyone with experience traveling into MIA on international flights with any ideas as to whether this new timeframe (1:45) is likely to be sufficient? I am guessing the AA international arrival and AA domestic departure for the next flight is in the same terminal but don't know. Will I also have to go through security again once through customs and immigration? Thanks in advance. TK
