I was on a flight last Fall to and from Baton Rouge the same day. Not many flights in and out of there. When I landed, I got a text asking if I was interested in giving up my return seat for $800, and would be driven to NO and fly out of there later. Would have taken it, except the $800 was a "voucher" that was good for a year. Had no travel plans to fly in that time, so passed. Otherwise, for cash, I would have jumped on it. For the right dollar, there is always someone willing to be delayed for a few hours or even a day.
