I don't know that they are even doing that. I am looking for 2x JFK-ICN-SIN and it is completely impossible a year out. I am seeing one seat on the JFK-ICN segments but never two except for occasionally the very first day the flight becomes bookable. As for ICN-SIN all I ever see is economy... and it used to be the other way around (easy for the SIN flight, hard for the JFK). And not a single first class for even one passenger a year out. And this is using KE's own miles.

What is the best strategy here? Is it possible to book the ICN-JFK in biz online then call/chat with KE to have them add on the ICN-SIN segment in economy, then I keep checking for biz to become available? And what about round trip? Looks like the only way is to book a one-way then wait and separately book the return. I have a suspicion this increases the "carrier imposed fees".

Thanks
