What would be the likely benefit of China Airlines for award travel US - Asia? The only route I can find with lie-flat seats (although hopefully I'm missing more) is LAX-TPE, but that's only in 1st which I don't believe would be bookable with DL miles. Would there be anyway to use this airline to get from the US to SE Asia (say, BKK) on them? Would be nice to have another option given KE's tremendous blackout dates.
