<font face="Verdana, Arial, Helvetica, sans-serif" size="2">KE's Japan - Korea award is the worst;
35,000 miles for regular season and 55,000 miles for high (peak) season with Y-class.

It is a very poor value, but NRT-ICN on KE in August is almost always sold out, even in F. Supply and demand at work here.
I think most of the alliances' Y RTW awards are overpriced, as one could get much better value for the mileage asked.
