Thanks to everyone who has been contributing to this thread.
Have my first transfer at Shanghai next April. Unusually for me, it won’t just be me and LapChild. MrLapLap will be travelling also.
We’ll arrive at PVG at 7:30am and leave for NRT 9 hours later.
Am assuming we just need to collect luggage, check it back in and will have about 5 hours to roam around. That’s the norm for PVG, isn’t it? Or is China Eastern Airlines now an exception?

On the way back we will arrive at Hongqiao Airport 17:10 and then transfer to Pudong Airport for departure flight at 1:45am. As we’ll have luggage with us, am expecting to just get the airport to airport bus transfer service. Looking at a map, the Metro line 2 seems logical, but I am getting the feeling that it wouldn’t be.
All of us are violently taxi averse (even my kid hates travelling in cars, preferring buses and trains)
