Avios tickets from US to Japan
I'm trying to find award availability from US to Japan in J. Looking for award on BA.com, I see only premium economy available, no business class (as far I know all the routes are 3 class cabins, with B787). I read somewhere that F awards are not available from US to Japan on JAL. Could it be that on 3 class flights, they remove J award tickets?
Any tips/hints how to fly from US to Japan west bound on Avios?
