I just booked my first award flight! AUS -> SFO -> ICN -> HKG, PVG -> ICN -> SFO -> AUS for the wife and I next October. Transpacific and China flights will be in Asiana business class, courtesy of the US Airways Dividend Miles south Asia sweet spot. I managed to get the Asiana seat selection tool to work thanks to a Flyertalk thred, but one leg (PVG -> ICN) isn't showing up for me. Managed to select all of my wife's seats without a problem (the leg isn't missing for her). Has anyone run into this problem before? Should I call US Airways or Asiana to resolve?
