"The security processes are the same for mobile Web as they are for regular Web. Just imagine it as a miniaturized version of a regular Web site. And the big plus is that you don't have to have a printer—I mean, that's really the big convenience—and then not have to worry about rushing to the airport early to stand in line somewhere and print out a boarding pass. You have it on your phone as you check in, ready to go, and you just show it and go."
Borucki says a TSA screener will confirm the bar code's authenticity with a handheld scanner. Currently, the option is available if only one customer is listed on the reservation.
"And you'll step through the Web check-in process on your mobile phone's browser, just like you would as if you were sitting in front of a computer. And when you get to the boarding pass page, instead of printing out a boarding pass on a printer that's attached to your computer, you'll just see the boarding pass on your phone with a bar code, and you take that phone with the bar code to the airport, and as long as it's a participating airport, you can scan it at the security checkpoint, then go on to your gate. And when it's time to get on the plane, you scan it again at the gate door, and you're on your way."
