They're not charging you for this, and implementing it doesn't affect your flight experience one way if you choose not to use it. nwa.com has long been on the leading edge of providing travelers with complete control of their travel experience, and this is just another piece.

Why are you so negative? And how was this "spun"? Did I take something obviously negative and put a positive spin on it somehow? I don't think so. Also, name me another airline that does provides this. I'm not aware of one. Lighten up a little and go watch some fireworks.
