I am considering getting flight tickets from Europe to Japan with Air China, and I can pretty much choose whether to transit at Beijing (PEK) or Shanghai (PVG). Are there any practical advantages of one over the other regarding transfer procecures, customs/immigration, luggage check-through, ...?
All flights would be on one ticket issued by CA, will all flights operated by CA as well.
PEK is working overload this year, meaning there is a lot of congestion at PEK. Assuming that the prices are similar, I would choose PVG as the lines are much shorter. If flying into PKX (Beijing Daxing International Airport) is an option, then PKX would be the best option as you would have less walking to do between transfers and since it is newer, you get fast WiFi and good modern technology. It has very short lines and the flights from LHR to PKX to Japan are shorter than those at PVG.
