How much would you take to be bumped off your next flight? Delta Airlines wants to know. In advance. You see they figure they can save some serious bucks if they know your price going in. No more announcements of flight vouchers for $200, $300 or $400. You’ll just register your price when you check in at the airport kiosk, and when they need your seat, they’ll bump you for that amount. They even tip you off that, “Delta accepts lower bids first”. Of course they do. Me, I’m the Dr. Evil of the air. I’m not getting off that flight for less than “$1 million dollars”.
