Mobile Future

I am serious.  And don’t call me Shirley.

The legroom has shrunk and Pepsi is two bucks a can.  But one thing about air travel that’s becoming a lot more convenient is the check-in – thanks to your cell phone.

With new technology and a nod from the International Air Traffic Association, airlines in the U.S. and Europe are increasingly allowing passengers to walk through security by flashing a coded graphic on their phone displays.  (Yes, you still need I.D.)

As the Atlanta Journal-Constitution reported Sunday, this kind of ticketing is expected to grow from 37.4 million transactions in 2007 to just over 1.8 billion by 2011, the majority of which will be for air and rail travel, according to Juniper Research, a firm in Hampshire, England.

Using the web, phones access and display an encrypted bar code with passenger and flight information. Transportation Security Administration officials scan the phone at the security gate and you pass through.

The lines in front of most airport security gates no longer look like the start of the Boston Marathon but even so, it’s still nice to have a newer, more efficient way to keep the crowds moving.
