The Transportation Security Administration (TSA) of the Department of Homeland Security continues to phase in security procedures in order to lessen the threat of terrorism. Airlines are required to submit certain data to the TSA to check against their ?no fly? lists before a boarding pass can be issued. This information is being expanded to include the passenger?s full name, gender and date of birth for all commercial flights, and must be identical to that as shown on the photo identification to be presented at check-in. For international flights, a passenger’s citizenship, passport number, expiration date and issuing country must also be supplied. To facilitate check-in, travel agents are now beginning to request this information when making airline reservations.
