An estimated 10,000 people have enrolled in a government-run test program for speeding passengers through US airport security checkpoints, Homeland Security Secretary Tom Ridge said on Friday.

The Registered Traveler program, which pre-screens passengers for potential security risks, is supported by airlines, which are trying to retain their premium business customers and reduce airport wait times for all travelers.

"I believe if we reduce the congestion at busy checkpoints that will in itself enhance security and better focus the efforts of our screeners," Ridge told reporters at Washington's Ronald Reagan National Airport.

Reagan National, where American Airlines is participating, is the fifth and final US airport to begin testing the Registered Traveler concept.

American is also working with its frequent fliers in Boston, while United Airlines is pairing with the government in Los Angeles. The other programs include Continental Airlines in Houston and Northwest Airlines in Minneapolis.

Airlines are seeking their frequent fliers who travel at least once-a-week out of these airports. The government is spending USD$10 million on the pilot this year and USD$15 million has been budgeted for the fiscal year beginning October 1.

Under the program, passengers provide the Transportation Security Administration with basic personal information at airport kiosks.

Names, addresses, phone numbers, and other information are cross-checked with security databases. Volunteers will also be photographed and submit fingerprints and biometric eye-scan checks to ensure proper identity.

Passengers who clear screening, which takes about a week to complete, will receive a card that will be scanned each time they check-in for a flight. The card will enable them to proceed to a special security line, exempting them from a second round of security checks unless they trigger suspicion or set off alarms.

Some security experts are not convinced the program will be secure enough since millions of passengers pass through US airports daily.

Another concern is cost. Ridge indicated the government may impose a fee. Airlines already complain there are too many taxes and fees, which undercut their pricing power and scare away business.
