I previously had no problem on two different trips booking business class award seats on KE using DL miles, but I have struck out trying to get two award seats to BKK for next May. Flights from ICN are available, but I can't get to ICN either on KE or DL. I went ahead and booked on China Southern, but would prefer KE. Does anybody know if award seats open up on KE as the departure date gets closer?
