ime lots of TAs in asian neighborhoods have access to bulk mu fares. the guy i used to use is no longer in existance, but methinks a quick survey of the yellow pages should yield acceptable results.

note, i've never seen consolidator j fares on the aa codeshare.

if you don't want to fly mu, you could do what i used to do when i flew business class (previous job). that is, fly to sel on sq, oz, or ua (not sure if ua flies sfo-icn these days) and buy a separate ticket from there. my total cost was usually around 2400 (i would fly y between icn and pek/pvg when necessary in order to keep costs in that ballpark).
