I had miles taken out of my account for a flight on 9/11/01 (flight ticketed the night before) from BOS-LAX - and I most assuredly was not the user of this flight (I'm based on the other coast!). I was pretty creeped out about this (discovered it a few days later when looking at my online account status while trying to reschedule a trip). AA customer support took a few days to get it sorted out, but eventually the miles were reinstated to my account. No "bonus" miles or anything of a courtesy was offered. I was just glad to get my miles back.
