USA Today | Boarding a plane without an agent to inspect or take your pass has arrived in the USA.
Continental Airlines has confirmed it's testing the procedure at a gate at its hub in Houston Intercontinental. It's the first experiment at what's called "self-boarding" in the U.S.
In self-boarding, passengers — much like customers of the New York City subway—swipe their boarding passes at a kiosk reader at the gate. That opens a turnstile or door to the jet-bridge. Although an agent isn't there to take the pass, one is typically present to handle problems and other customer service tasks.
