Round-trip flights from Houston (HOU / IAH) to multiple destinations in China are on sale at the moment. Airfare starts at $714 with either one or two connections. Delta is the operating airline. There is a stopover component for this fare basis, but it’s not very useful since it will only allow you to do the stop at the American gateways.
[11/26/2014 @ 9:34 AM] Fare gone. 🙁 Seems to price at around $1000 now.
