When checking in online at Northwest Airlines' website, I got prompted to
volunteer if I had flexible travel plans. This is a very nice innovation,
stopping us from having to make the offer there in the terminal, taking up
the gate agent's time. Neat. Then, when I clicked through to "volunteer",
I got the next question: "How much would you be willing to accept in order
to volunteer? Lower bids will be accepted first."
Well played, Northwest. Well played...
