I'm going from BKK to PVG (Shanghai) on January 14 and found myself a connection with China Southern through Guangzhou arriving at PVG at 4.20pm. Perfect times for me. My only concern is they 1H 40 Mins connection time in CAN. Would that be enough to clear immigration?
I read somewhere that minimum connection time is 120 mins, but China Southern allows me to purchase these flights. Do you think it will be ok?
