I don't know. Maybe NW is going to put in business/first type of class for flights to Europe, i.e, matching up with CO. Thus more restrictive. Would make this new measure more sufferable. Well...

Of course, NW would surely improve its b class service with these restrictive measures (?)--let's just hope they don't attempt to copy CO's "30-day maybe or maybe not" upgrade policy.

My intuition is that there's got to be something else going on...let's hope so.
