Yep preselected seat, centre rear were the only ones left. Maybe because the booking was only about 2 weeks in advance didn't help, but my QF FF number was definitely in the booking. This was late 2010, so maybe things have improved. Any way doesn't matter I have sub Jetstar expectations of most US domestic carriers when in Y.
I had this in late 2010 on an AA code. Didn't recognise my QF status and only offered rubbish seats. I called in and they were able to assign better seats.
