Just so you know, we also traveled through CLT to BDL. The flight left SXM late, had to go to Puerto Rico for fuel- Really?!?! So of course we did not make our connection in CLT. Most of our flights have left SXM late. Take the time you are given for your flight and subtract boarding time half an hour prior. That is the time you have to get from the gate, collect your luggage, go through immigration, recheck your luggage, go through security. If you need a potty break or food, forget it!! We had a tight connection. Flight went to PR, missed connection to Hartford, nothing left except standby. 4 of us, only 2 caught the flight. Had toyed with driving home. Was very miserable for the 2 left behind. Crappy hotel....next day, connection to Boston which was on lock down because of the bombing. US Air does not care. Connections in CLT are always tight. Wish you luck!
