Just a curious thought.
take off the NW
KLM worldwide reliability logo when they put the SkyTeam logo on the a/c? Delta and KE
have the logo on the front of the a/c near the forward door. This would be a logical place for NW
to put the SkyTeam logo as well.
As most a.net people would know, NW
and KLM have a unique relationship. They essentially started the world of true codesharing, and the relationship will continue even when both are in the SkyTeam. The began revenue sharing over the Atlantic before most airlines even considered codesharing.
