China Southern, a member of the SkyTeam Alliance, is putting flights from San Francisco, California to Shanghai, China on sale! Flights start at $399 round-trip, after taxes with very good availability in September and October.
Note that Google Flights will price the flight at $400, but it will be $399 when booking either on Priceline or direct through China Southern. Feel free to take pictures of the how you spent the dollar you saved and send them to Josh Trips!
To find this deal, use Google Flights and search for business class flights between SFO and PVG.
