I have a bunch of points in my Chase account. I plan to use them for two off-peak biz/F tickets from JFK or LAX to ICN. I intended to transfer those points to United for redemption on Asiana. But I noticed on this forum that since the introduction of the A380, members have stated that award tickets are now easier to obtain on KE.

Does anyone have experience in booking two biz/F award tickets on KE and OZ (via United)? How was the off-peak availability?
