I've been upgraded about 40% of the time when they were flying the 747 to NRT, even got a seat in the First Class part of the plane a couple of times as a D+. About 60% on the early flight on the 330 to NRT and about the same to ICN on the 1330 flight. It's going to be interesting to see what happens since it looks like OZ is going to the 321 for the late flight to NRT and the early flight the next morning and a 380 for the two later flight along with an Air Seoul 321 that looks like an additional flight pair.
