Ditch....
I'm guessing that that cielazur is QCCA......but I don't remember those polar flights being all that popular so a chat with your manager might do the job cielazur.
Undoubtedly,someone in the office will correct me but I would imagine that they don't have enough 380's to do them yet so they will still be 400's.
It depends what aircraft you operate on cielazur...
