A member asked the FD Helpdesk just recently, if CO provides upgrades for Royal Wings and the answer was NO !!
I guess, they have to rethink this, just because right know CO seems to be only an alternative, cause they are offering double points one month longer than NW/KL.
Not many priveledges so far on CO, at least they could offer systemwide lounge access and ( or )domestic upgrades....
I am free of any prejudices, but should a KL RW use CO, if NW treats us much better....???
