Fly Round-Trip from NYC/DC/Cleveland to Beijing/Shanghai for $556 on American Airlines

Unlike previous offers, this has no minimum stay and is available for April and for September to December 2016 bookings.

American – $556: Washington D.C. / Newark / Cleveland – Beijing / Shanghai, China. Roundtrip, including all Taxes

This will also earn you about 16,000 AAdvantage frequent-flyer miles, worth roughly $200, so the true cost is only about $400.

Book with a premium Chase credit card to get trip-delay protection. That would have served me well when I was once delayed on a Shanghai-to-USA flight due to a typhoon.
