Well, I just asked for my wife, a NW silver, for comp to CO. Within the last four weeks CO has a new policy not to comp NW elites...I asked several times. FYI.

However, prior to this I have found CO very accomodating, in that they will listen carefullly to your situation. NW is more absolutist with respect to rules. So all is not lost. I also believe that you may be able to switch over the miles or segments, if it's not too many. I've been told that when posted in error, a NW miles credit can be changed to a CO.

I really wish you well with this.
