US Secure Flight Requirement

The secure Flight requirement of the US Transportation Security Administration (TSA), which requires airlines to collect Secure Flight passenger information from individuals travelling to/from/via the USA, came into force on October 31, 2009.  In connection with the flight booking, passengers must declare their full name just as it appears in their passport, as well as their gender and date of birth.
The airline sends the information to the TSA 72 hours before the flight departure time.  The TSA compares this information with watch lists with the purpose of identifying suspected terrorists, preventing access to flights by passengers prohibited from flying, and identifying individuals for whom an enhanced security check should be performed.  When a passenger’s information has been compared with the watch lists, the Secure Flight system sends the result to the airline.  If the screening result is negative, the passenger cannot be accepted for the flight without further investigation.  However, any subsequent information might change the result to positive, in which case the passenger can be accepted for the flight.
An airline cannot accept an individual on to a flight if they lack a Secure Flight screening result.  For this reason it is important that the required information is found from the reservation, at the latest, 72 hours before the flight departure time.  If a booking is made closer to the travel time, the airline will deliver the information to the TSA in connection with the booking confirmation.
