I'm trying to book a flight from PVG to TAO (Qingdao)
My AA flight supposedly lands in Shanghai at 3:05pm. Assuming I don't check bags (which is going to suck for a 6 day trip), would I be able to clear immigration and make it to the 4:20pm Air China flight?

I believe both AA and Air China are in terminal 2.

Alternatively, there's a 6:45pm flight out of Hongqiao airport. Has anyone transited between the two?
