Thanks, yes, it's down to around 12 hours now.

The flight was already busy when I booked so it is possible overselling is a factor. I'm not due in until about 2 1/2 hrs before the flight due to a little jolly boy tier point run on AAnother AAirline first

I don't fancy being re-routed, however, if it does mean moving to a comfier cabin, then it may be worth consideration . However, if this is the case, and being a GC holder, I would hope I get the option rather than be pushed !

Thanks for the info anyway.
