In the wake of the tragic crash of Virgin Galactic's SpaceShipTwo during a test flight, much discussion has centered around the celebrities — such as Justin Bieber and William Shatner — who have purchased tickets to ride into space once commercial flights begin. The media is referring to them as "astronauts," but Jerry Doyle takes a different view.

"Really? Is that what you're going to call Justin Bieber? An astronaut?" asks Jerry on his national talk radio show. "No. Basically what they are is meat in the seat."

In the airlines industry, the success of Spirit has helped to legitimize practices that treat passengers, in the words of one consumer watchdog, like "meat in a seat." When a carrier assumes the moral status of its customers to be different from an ATM only in respect to daily limits, monetizing the mistakes of first-time flyers can be a lucrative business.
