Airlines OK Standard for Cell Phone Check-in

Wow, soon we won't even need to show up. Oh wait, we still have to show up so we can be searched, x-rayed, prodded, and take off our shoes.

Major airlines have agreed on a standard that will allow travelers to check in using a bar code sent to their cell phones, the International Air Transport Association said Thursday.

Passengers will register their cell-phone number when buying a ticket and receive a bar code by text message, the group representing most commercial carriers said.

That's actually very cool, and we understand the IATA wants to completely phase out paper tickets, but what happens if you leave your phone at home?
