In case anyone has expired miles within the past 18 months and is contemplating reactivation.
I just found out today that AA now only allows reactivation for miles expired within the past 18 months.
It used to be much longer - you could activate as long as miles expired after 2002.
Unfortunately my miles expired earlier than that. I called customer service and apparently it's a recent policy change but they can't do anything about it.
I searched my email but didn't see any relevant communications. Not the surprise I was looking for when there's finally necessity to reactivate my expired AA miles.
