I am traveling to Bonaire in April. UA notified me (didn't get an e-mail, just found it when I logged in) that there had been some schedule changes. Not unexpected as I booked way back in June and haven't paid close attention since then. I do have Global Entry, but the schedule change has left me with 1'34" between planes at IAH to clear customs and make the next plane. Is this reasonable? Possible? Should I call and ask for the next later flight IAH-LAX?
