The Secure Flight program, as implemented pursuant to the 2008 Secure Flight Final Rule, requires commercial aircraft operators traveling to, from, within, or overflying the United States to collect information from passengers and transmit that information electronically to TSA. This information, known collectively as Secure Flight Passenger Data (SFPD), includes PII, including full name, gender, date of birth, passport information, and certain non-personally identifiable information provided by the airline, such as itinerary information and the unique number associated with a travel record (record number locator).
