The "No-Fly" and "Selectee" lists managed by Federal agencies through the joint Watch List Advisory Council (WLAC) aren't the only blacklists and watchlists that are used to determine who is given US government permission to board an airline flight, and how they are treated when they fly.

Senior members of relevant House and Senate Committees are asking overdue questions about the blacklists created and used by the Transportation Security Administration (TSA) to target selected travelers for special scrutiny, surveillance, and searches when they fly.

The TSA's Secure Flight program is used to determine, on the basis of identifying and itinerary information from ID documents and airline reservations, what Boarding Pass Printing Result (BPPR) to send to the airline for each would-be passenger. The ruleset included in the Secure Flight algorithm includes list-based and profile-based Quiet Skies rules created by the TSA itself, independent of the interagency No-Fly and Selectee travel blacklists.
