Not sure why Northwest didn't make the site, but they are getting so ridiculous on fees, it's almost comical.

They charge $10 for an aisle seat, and $25 for an exit row seat. Try to travel with a family of 3 and they will tell you they can't find 3 seats together. Call to talk to an agent to get those 3 seats together and they will probably do it for you, but then they will charge another $15 per ticket to talk to a person.

NW charges $25 for the second bag, unless you're flying First Class, or full-fare coach, or you are an Elite member or you purchased your ticket before May 1, or if it is a carseat or a stroller.

They also sell snacks on the plane for $3, but the last time I flew I got it for only $2 because they could make change for a $5.
