Most recent two appeared on the AA app closer to the departure date rather than say 2 days later like BA might do. First one was offered at a self-check in kiosk.
First years ago from DCA to somewhere; second from RIC to BWI or somewhere last year ($50 or so, but got upgraded anyway); third one was a longer domestic, maybe a transcon (flat bed may have have decent enough for $250?, but I can survive a Y seat).
Didn't take any as there's no additional tier points for BAEC members. You only get, say, the 10TP for the economy fare rather than 40tP for the first class cabin upgrade.
Unless it was a mistake, I just got the J 40 tier points on a recent app upgrade last week.
