TSA incorporates unpredictable security measures, both seen and unseen, to accomplish our transportation security mission.
Security measures begin long before you arrive at the airport. TSA works closely with the intelligence and law enforcement communities to share information. Additional security measures are in place from the time you get to the airport until you get to your destination.
TSA adjusts processes and procedures to meet the evolving threat and to achieve the highest levels of transportation security. Because of this, you may notice changes in our procedures from time to time.
TSA counts on the traveling public to report unattended bags or packages; individuals in possession of a threatening item; and persons trying to enter a restricted area or similar suspicious activities at airports, train stations, bus stops and ports. If You See Something, Say Something™. Report suspicious activity to local law enforcement.
Passenger screening at the airport is part of TSA’s layered approach to security to get you safely to your destination. TSA’s screening procedures are intended to prevent prohibited items and other threats to transportation security from entering the sterile area of the airport and are developed in response to information on threats to transportation security.
