It's $150 per instance of changing. So if you changed 10 flights at one time, it'd be $150. If you changed one flight 10 times, that would be $1,500.

I don't know if you can leave any segment "open" on the current RTW program. Knowing how they've tightened up on everything else, probably not.

I'm still probably going to buy RTW tickets on NWA ticket stock, but if they start cancelling segments on me before I get over to Thailand to make the purchase, I'll probably start calling consolidators and/or RTW specialists to find out about options for ticketing that don't involve Northwest.
