Flights to/from NRT
 

I see this plane is operated by the A340. Are all A340's have the new business class cabin and does the NRT flights have it on a consistent basis?

Shouldn't take that much searching to find the relevant info, but all longhaul planes except one (LN-RKP) has the "new" cabin.
SK claims LN-RKP is just a back up plane, however it tends to fly regularly. It's flying today and was yesterday as well, but had 4 days still before then....
LN-RKP have previoulsy made it to NRT, but I believe it's pretty rare.

There has been a rate occasion if LN-RKP coming over here to Tokyo. But the Tokyo route is treated far better than most long haul routes, so the risk of getting anything but the new cabin is extremely low. Rumour is that the route is performing extremely well on earnings,hence to golden treatment.

We are taking this flight on Christmas Day and a A330 is allocated to it although I think thats not very common. As its our first J flight of any kind we are both and crossing our fingers that LN-RKP doesn't make a unwelcome appearance.

We don't see many A330s over here. Though the four new ones do have the range, and the older ones can make it with some restrictions.

I am guessing that reduced schedules in the Christmas days makes a bit more unusual scheduling of the planes. But reduced schedule should make LN-RKP even less likely. Though as always, we have no certainties.
