So the Delta One option vanished rather quickly. Still something there from NGO, but not excited by the extra time and cost to get there.

However, UA started showing some OZ (also CA), both seem like good choices.
The mileage cost is more than KE, but less in fuel/taxes, so pretty much a wash.

Probably do KE KIX-LAX, purchase a cheap one way to Denver since I don't think the domestic 2hr leg is worth the extra 18,500 miles for a Skyteam award.

Then DEN-KIX on either OZ or CA. Bit of a tossup here.
