Flying through PVG now. The wiki needs to be updated?
Gate 68 is also a Priority Pass lounge. The one shower is a godsend after a humid, rainy day outside traveling. (Granted, the hot water became frigid every few minutes - I presume related to the plumbing and other restrooms, but beggars can’t be choosers.)
The Air China lounge is at Gate 71. It is a Star Alliance lounge, but American is listed as an eligible airline to use the lounge. The buffet style food options on floor 2 were above average. Tasted above average, looked average. I just went to the restroom, and noticed they have 4 shower lounges also. D’oh!
