The flights MCO-MIA-BZE were better than expected. The crews were pleasant and helpful. The flights coming home BZE-MIA-MCO were the opposite. We missed our connection in MIA because of AA didn't think we had enough time. The shoved us into a reschedule line. There were 2 clerks with 1 person watching, she never helped. We could have made the original flight. The hop from MIA to MCO the crew had to be tired because it was all business. Water only.
