Thanks for the information, useful.
I have just under 5 hours at PVG for my next MU/FM transit. No idea where arrival will be docking, but expect to depart from T1 on return to AMS. Is it possible to go back and forth between T1 and S1 just for a lounge? But would like to take a look.
Yes you can, the shuttle between T1 and S1 has a divided, small, compartment, specifically for pax going from S1 airside to T1 airside. Most pax on that train (in the main compartment) would be going from S1 airside to T1 arrivals.
Here's a pic of the mini S1-T1 compartment and the signage on the floor (taken at S1).
Not sure why 137 lounge entrance uses SkyPriority (which has nothing to do lounge access) instead of STE+?
