I had an airport transit (hand luggage only...) inbound from Budapest and onwards to Macau two days ago.
Compared to PKX a couple of days ago it was a breeze....but I guess the amount of passengers play an important role here....because in PKX we were three passengers in total.
The PVG transit area however was quite full.
The vending machines at the gates did not accept 10 RMB bills, therefore I had to wait until the shops open up.
