Hi everyone, I've read through this and the other long FAQ thread, but there were sometimes differing opinions based on spirit of the rules versus what's allowed. I have a trip to SYD that is a little too long, and would like to use the 48 hour TWOV in PVG.

My main issue is separate itineraries/tickets. Would this be ok, or too confusing for those involved (check-in staff and immigration folks)?

US passport
SYD-BKK-PVG (TG award; arrive in PVG at 0625 on 10/21)
PVG-HKG (KA award; depart PVG at 1850 on 10/22)
HKG-SFO on 10/23

Is this 36 hour PVG trip doable? Thanks a lot all.
