This is a real pain - I am planning a RTW trip for this fall, and the NWA ticket would be by far the best option (because of the destinations served) if it weren't for this new fee.

Let me just see if I understand how this works now. If I make changes to 10 different segments of my itinerary at once, I get hit with one fee of $150, right? Or would it be $1500?

And is it possible to avoid change fees by leaving my itinerary completely open (i.e., when I buy the ticket, don't book any flights other than the first leg) and then just adding segments as I go? Or would that cost me $150 each time?

Finally, if I buy through KLM or one of the other partner airlines, will the rules be the same?
