Well if your looking for award seats its time to start now. I'm currently booked on AA in F.
Arriving PVG on 11/10/11
Departing PVG on 11/16/11
My flights are not set in stone because i'd rather pay the extra 5K points to use a non-us based airline ( no availability yet). Not sure if i will be able to handle AA F after flying CX F in May

. There does apear to be CX F available but I'd have to take extra vacation days to get it.
