How about this: When buying your airfare; get a discount if speculate right on fuel prices or pay more if you’re wrong.
AllegiantAir wants it’s customers to be able to gamble on fuel prices. They’ve written a letter to the Department of Transportation asking for permission to allow their customers to be able to choose between a traditional fixed-price ticket and a discounted, variable-price one. If the price of jet fuel falls by the departure date, customers with a variable ticket would get some cash back. If the price climbs, they would pay more, up to a pre-disclosed cap.
Or how about specialized beer for astronauts and for space travelers?
