Cell phone as boarding pass

There are obviously things that can go wrong here, but a printed boarding pass is no more secure than your phone, and you're less likely to forget the phone. This is one more reason to keep your phone charged - a good thing.

"Continental is testing a new system that allows people checking in via their cell phone to get their boarding pass sent directly to their phones. The electronic boarding pass, which has an encrypted two-dimensional bar code, can be used instead of a paper boarding pass to get through airport security and to board planes, according to a story published Tuesday in The New York Times.

Several U.S. airlines, including American, Continental, Delta, Northwest, Southwest, and Alaska, have already been allowing people to check-in for flights via their cell phones. But they still have to print out the tickets at a kiosk at the airport or a computer printer before they arrive at the airport. Continental is the first airline in the U.S. to test the new electronic passes.

The Transportation Security Administration, the federal agency that oversees security for airports, likes the electronic boarding passes too, because the two-dimensional bar codes are harder to forge than the one-dimensional bar codes that are used today on many tickets printed online.

The TSA has been working with Continental since December to test the new electronic boarding pass, the Times said. Continental is only using the new boarding pass technology on nonstop domestic flights out of its hub in Houston. But the airline will likely expand the service to other airports later this spring.

Harteveldt told the Times that a mobile check-in system also has other benefits. For example, airlines can communicate directly with passengers about on-board services, provide information about baggage pickup, allow passengers to upgrade or change seating, check standby status, and help rebook canceled or delayed flights directly from their cell phones.

All this sounds terrific for a busy traveler such as myself. But for all these services to work as advertised, indoor cell phone coverage will have to be beefed up in many airports. It also wouldn't hurt if airports added more power outlets."
