The high cost of fuel is primary when they power up for the take off. Once airborn and at cruising altitude the saving on fuel begins. I suggest they fly nonstop from coast to coast. Fly over the bigger cities and push people out the back door with a parachute once over their destination. Right before the push, they ask for a couple of bucks for the chute packed by a qualified person. Or maybe they could come in with out power like coasting down a hill with out pushing the gas pedal. I am all for the higher costs, it eliminates the peeps who come drunk, with kids, or are fat. Those peeps will not have the bucks to fly, making it more enjoyable for me.
