I was tracking the Prestige Suites on the 748 and 77W, but for some reason I had completely forgotten that some of the A330s also featured the suites. Thus, I was completely surprised last week when both segments of my NRT-ICN-SIN flights featured the Prestige Suites. Probably the nicest business configuration of any A330, in my opinion. As an added benefit, I was the only J passenger on the NRT-ICN flight!
