although AS F is currently a pretty sad product, upgrades are one of the major things that keeps me interested in maintaining status. i am also concerned that with the VX acquisition and the retrofitting of the AS fleet to "enhance" Y+ and F, that F upgrades might go away or only be accessible with GGUs. time will tell...
anyways, i just made a reservation for November the other day, and F waitlisted still shows for me. YMMV.
