Called AA this afternoon after a schedule and/or equipment change altered my reservation. The computer system automatically rebooked the transcon business SAAver award to an earlier flight, so I called up to ask to be placed back onto the later flight. The agent said she would have to call revenue management to make the change, and when she finally came back on the phone, she asked if I'd like to reserve a seat over the phone. I declined and offered to pick one online.

When I finally got around to looking up the reservation online, I realized that my U business award was now a Z award. The seat selection tool only allows me to pick from the first class cabin of a three-class aircraft. So far, no miles have been taken from my account and the booking reads "ticketed." Should I worry the I will be denied boarding or charged extra miles? Or is this just a mistake that works in my favor?
