The final Secure Flight Final Rule shifts pre-departure watch list matching responsibilities from individual aircraft operators to the Transportation Security Administration , believing TSA can better remedy possible misidentifications when a traveler's name is similar to one found on a watch list. Airlines will be required under Secure Flight to collect a passenger's full name, date of birth, and gender when making an airline reservation. This additional information is expected to prevent most inconveniences at the airport, and will be particularly important for those individuals with names similar to those on the watch list. TSA will receive limited information for each passenger, as well as for certain non-traveling individuals, such as those escorting a minor or disabled passenger to the gate. TSA will determine if their information matches the No Fly or Selectee lists and will transmit results back to airlines. Data retention for the vast majority of individuals will be no more than seven days. Secure Flight will be implemented in two phases. The program will initially assume the watch list matching responsibility for passengers on domestic flights from aircraft operators beginning early 2009. In a second stage of implementation, which is targeted to begin in late 2009, the Secure Flight program would assume, from Customs and Border Protection and the international air carriers, the watch list matching function for passengers on international flights.
