They will upgrade KL Royal Wings first.Who comes next raises the often discussed question again....???
Do they take NW Elites first or their own KL Silver Wings ???
As far as I know the cooperation between CO and KL starts Dec 1st and even after that date, your chances are non existent.Dito for your companion.
I would arrive very early to make sure, that you get good seats, to be honest both KL and NW does not care much about reserved seats, if the ship is full...
Sorry about that...
