BOS-PEK $806 ai non-stop on HU September 2014 - Mid December 2014
Definitely not MR material but you can get a $806 roundtrip on Hainan from BOS starting in September. No word on whether AA is codesharing on this yet so it looks like only earning in HU's program.
. If China is on your bucket list then this may be the time to do it. It also only operates 4 weekly (1356). Some dates have lost the lowest fare codes
You can play around with tours that stat in PEK and end it PVG/SHA (use SHA for HU) and get a flight for under $850.
