Flying a sports car
rather than in a bus. Nothing quite like the push back in your seat when you accelerated down the runway.
And you could get a standby seat on the evening flight from JFK for about $500. It was cramped on board and "most" people prefered to fly subsonic, have a nice meal and sleep on the 747.
It doesn't matter how much it costs. The rich will afford it. We plebs don't count.
