Thanks for the info, doc.
I'm a CO elite so I might pester CO to get me a pass ("Uh, I'm sorry you can't come to an agreement w/KLM over Wings...but next time you talk w/them, could you ask'em for a couple of lounge passes for me?"). Actually, I'll call NW first about the "benefits" of flying WBC.
I forgot about the Amex angle. I've never used the lounge benefit since I try to schedule tight connections, but this is an ideal situation to finally take advantage of this benefit.
Now, if only I could make up my mind about what our final destination will be for our Thankgsgiving getaway...
