American is offering up to double redeemable miles for nonstop flights to China flown between January 23 and March 31, 2012. This applies to their three nonstop China routes, between Chicago and Beijing, Chicago and Shanghai, and Los Angeles and Shanghai.
Through this promotion you earn double AAdvantage miles for paid first and business class tickets, and 50% bonus miles for select economy fares (Y, B, H, K, M, L, V, S or N).
Registration is required using bonus code USCHN.
Unfortunately my trip to China next week is ineligible due to the fare class, though I’m sure this will work out for others. It’s probably not worth paying a higher fare just to take advantage of this offer, but if you’re headed to China in one of those fare classes anyway…
