I'll be travelling on China Eastern airlines from South Korea (ICN) to New York (JFK) next week, with a 1-hour 45-minute layover in Shanghai Pudong (PVG). From looking around on the internet a bit, I've found a lot of conflicting information about whether I'll need to re-check bags and go through immigration twice (for arriving and departing). Namely, China Eastern's website says that for international-to-international travel, "Whether passengers need to pick up their baggage and check in again for through-check baggage" is a no.
Anyone have any clarification/recent experience with such a trip? More generally, should 1 hour 45 minutes be enough time to get through immigration and baggage, in the worst case?
I'm aware this is similar to an older question (International transfers at Shanghai PVG airport) but I don't have enough reputation to comment, so I made this new question.
