Spoke to a few AA reps on the phone about this, and in the most recent cases, they strictly said the ticket had to be used by 365 days from original purchase. She went on to specify the definition of used is "you boarded and your butt is in the seat and buckled." I asked for a corona extension, and they said no, including a supervisor who also said no. Seems like others above might have had different luck, and a HUCA never hurts.
