How Does This Selection Work?
The TSA uses a program called Secure Flight. This risk-based pre-screening matches passengers’ names against trusted traveler lists and watchlists. It helps identify low- and high-risk travelers before they even reach the airport.

A TSA spokesman explained that Secure Flight collects only basic personal details like your name and date of birth. This information ensures effective matching. The program also blocks people on the No Fly List and the CDC’s Do Not Board List from flying.

Don’t Panic—It’s Standard Procedure
Seeing “SSSS” on your boarding pass doesn’t mean trouble. It simply means TSA follows standard safety protocols to protect you and everyone on board. So stay calm—it’s all about keeping flights safe and secure.
