No more fumbling around for your paper boarding pass at the security checkpoint.

Now you can simply show the TSA agent your cell phone or PDA – as it displays the downloaded boarding pass. The agent then uses a handheld scanner on boarding pass bar code – and, you’re good to go.

It’s not everywhere yet, though -the pilot program is only available at 10 airports, and 4 airlines. Here’s the list:

Continental:

• Austin – Austin-Bergstrom International

• Newark – Neward Liberty International
• San Antonio International
• Washington – Ronald Reagan Washington National

Also note: Northwest plans to add Detroit to its roster of airports, soon.
