AA should be able to refare you back to your original Fare Code since the downgrade to B fare was against your will for no additional costs and that you should be number one on the Upgrade List. Also I hope you were not assigned to a middle seat at the back of the plane. Is there a way for an agent to ovveride the system to upgrade you and /or to assign you a Premium Seat and waive the cost? If you go to a red coat agent they should be able to waive the stipulations and have AAdvantage credit you the mileage difference between the B mistake fare and your original fare.

Did the OP ask to be rebooked in his/her original fare code? Did AA warn the OP that the B fare was only available? Wouldn't it have showed up on the AA.Com Itinerary at the time of rebooking?

I hope you get this resolved OP and you report back to us.
