I'm doing a similar routing next month on AA: SEA > DFW > PVG > DFW > SEA with 3 hours and 25 minutes in PVG between flights. I already have a valid 10 year visa for China, so that isn't an issue.
I'm wondering if anyone has any additional insight into what to write on the immigration form (i.e. Transit/Turn Around/Etc...). I just flew into PVG last week and had to fill out and submit the form at immigration.
Has anyone actually done a same day turn around in PVG that can share about their experience?
