US Airways, whom we refer to as useless (or I refer to as banned), because they're just incompetent, frequently comes up with interesting mileage promos-which you can use on otherStar Alliance carriers. See, as incompetent they are to fly, they're awesome
not to fly .
Anyway...36 transactions with their partners (some restrictions apply) gets you 100K miles, 90 of which will get you business class on your favorite *A carrier to Hong Kong or a couple of other Asian cities from the West Coast US or Westcoast Canada ( for Canadians, "WC" is one word lol). I know you can do YVR-HKK on AC in business.
Only issue is that it might be for US , or North American, residents only. If you live in an Asian country...the program is usually different. At least it is with DL and other carriers.
Anyway, here's the link:
