You might be able to board flights using just your cellphone, if a three-month test program by Continental Airlines at Houston International Airport is successful. Under the proposed system, a special code, in a mass of black and white boxes, gets sent to your cellphone or PDA. At the gate, the airline scans it with a barcode reader. You must still show photo ID. Air Canada has been using it since September and says the number of people using it has doubled every week since inception. Imagine that, a new security procedure that is both more secure, and more convenient. Just hope your batteries don’t run out.
