They were offering $1000 on Sunday for ATL-TUL, but it was a full 24 hours before the next available flight. I would have been peeved if I had underbid or even bid on such a layover.

At MSP a few weeks ago we had the infamous $200 gift card offer on the last MSP-MCO flight. A couple of us in the SP line just chuckled at the low number for a delay which required an overnight.
