UA sounds like the path of least resistance. But, I just ran a search for award tickets on UA, USAir and CO-Onepass and all three programs show no availability for random SFO - S Asia itineraries later in the summer, nothing for a whole month... not even the higher "Standard" award.
A search on ANA shows up multiple itineraries with LH and SQ for about 80 - 90K miles redemption.
Is this an IT problem? Is ANA able to show itineraries on all partner airlines while US based carriers are able only to show itineraries to airports they serve with their own metal or codeshare?
This is currently my problem at DL. I am sitting on hundreds of thousands of miles that I cant use because Asian and European Skyteam partners wont release award inventory to DL. If I had accumulated the same mileage on a Europe based Skyteam carrier, I could have been traveling now....
