I plan to arrive at Hongqiao from Korea, depart Pudong for SFO two days later. The scheduled times are 1pm arrival, 12:45pm departure.
Is this cutting things too close to qualify for the 48hr visa-free transit?
What would happen if my departure were delayed or cancelled?
Also, what fee, if any, is payable on arrival in Shanghai?
Presumably check-in staff in Seoul will want proof of permission to enter China, would they be satisfied with my US passport + PVG-SFO itinerary (on a separate reservation)?
Thanks for any advice - I'm wondering if I should I be safe and bother with the time+$$ to get a visa.
