Twice in the past couple months since we have been booked, AA has changed our departure. I'm not taking under an hour, I'm talking two hours or more change from the original reservation. We originally booked to leave MCO around 5:30 in the afternoon and arrive around 9:30 in OKC....Last month I was looking at my reservation (due to my OCD) and they had moved our departure time to 1:30pm. I called and they moved us back around the 5:30 range. I just checked this morning and they had us arriving around midnight. That was the final straw, I just called and they gave us a full refund and I'll book with another carrier. Word to the wise...keep an eye on your reservations or you might end up with some unpleasant surprises!
