I was booked on AA outbound with an overnight in MIA. I recently noticed there was a redeye available which I don't think was on the schedule when I originally booked. I called AA to try to change to the redeye to avoid overnighting in MIA. The agent said it would cost $2K additional! I declined after telling the clerk I had never before been charged anything additional for changing a flight. A few days ago I was checking on my flights, and my outbound had been changed to the redeye! I hadn't received any notification from AA about a change. I know they often "forget" to tell you about changes; in this case, however, I think the agent realized the error of her ways and changed it after we hung up. I still had to make seat assignments, which I don't normally have to do if AA does a change. I cancelled my MIA hotel and hope the redeye doesn't get changed. It's through LAX, which isn't my preferred routing, but it avoids a hotel, which is a plus. Happy camper.
