LN-RKP was allocated to the Cph-Ord flight I was booked on in Oct. has just now seen changed to an a330. If that sticks I will have to try for an upgrade to check out the pointy end. Unfortunately it won't be home though as C already has a fair few bookings even this far out.
Remember if you do get RPK, C is pretty good. A little old but proper flat lie flat seats not the angled ones. I slept like a baby last time I used it and by that I don't mean I woke crying every hour
