Do one way searches for the segments you want to fly to see if there is any availability that appeals to you. Depending on your balances this may make sense to do a redemption or redemptions and/or purchasing a return/open-jaw or one way ticket. May also be better to do West Coast-PEK(stop)-KUL(Stop)TYO(stop)-West Coast.
Happy searching. When you come up with something feel free to return for comments.
