Hi all, I am taking American to PVG, but I am on China Eastern out of PVG later that day.

I've had notorious problems getting foreign airlines to allow me to check-in online, and I'm wondering what kind of grief I am going to get, first of all, leaving LAX, and then getting to China Eastern Desk in PVG to get my next checkin, since I will not have a China Visa for that trip, connecting there.

Any advice or experience in such matters?
