Searching for flights to PVG next January and came up with this gem:

Flight CO87
Thu., Jan. 14, 2010 at 7:30 a.m.
Equipment - Boeing 737-700
Cleveland, OH (CLE) to Shanghai, People's Republic of China (PVG - Pu Dong)
Class: Economy (Y)

Not a cheap flight and imagine there are a bunch of refueling stops on a 737 from CLE to PVG. . . .
