"Department of Homeland Security (DHS) Secretary Janet Napolitano today announced that 100 percent of passengers traveling within the United States and its territories are now being checked against terrorist watchlists through the Transportation Security Administration's (TSA) Secure Flight program--a major step in fulfilling a key 9/11 Commission recommendation. Before Secure Flight, airlines conducted passenger watchlist checking. 'Secure Flight fulfills a key recommendation of the of the 9/11 Commission Report, enabling TSA to screen passengers directly against government watchlists using passenger name, date of birth, and gender before a boarding pass is issued,' said Secretary Napolitano. 'This program is one of our many layers of security--coordinated with our partners in the airline industry and governments around the world--that we leverage to protect the traveling public against threats of terrorism.' Under Secure Flight, TSA prescreens passenger name, date of birth and gender against government watchlists for domestic and international flights. In addition to facilitating secure travel for all passengers, the program helps prevent the misidentification of passengers who have names similar to individuals on government watchlists."
