How the Screening System Works
Before you even arrive at the airport, your information is screened through a program known as Secure Flight.
Airlines send passenger data—such as your full name, date of birth, and gender—to the TSA. This data is checked against various security databases.
The system assigns a risk assessment level:
Low risk (may qualify for expedited screening)
Standard screening
Enhanced screening (SSSS)
The goal is to identify potential threats before boarding, rather than reacting after takeoff.
This layered security approach became significantly more robust after the September 11 attacks and has evolved continuously since then.
Is It Only a U.S. Thing?
SSSS is primarily associated with flights involving the United States, either departing from or arriving in the country.
Even if you’re flying from another country to the U.S., American security protocols still apply because the airline must comply with TSA requirements.
Other countries have their own secondary screening processes, but they may not label it “SSSS.”
For example:
Security authorities in Europe coordinate with international aviation security bodies.
Border protection may involve agencies such as U.S. Customs and Border Protection (CBP) upon arrival.
But the SSSS marking itself is specifically tied to U.S.-mandated screening procedures.
Can You Remove SSSS From Future Flights?
If you’re selected once, it doesn’t necessarily mean it will happen again.
However, if you experience SSSS repeatedly—especially due to name confusion—you may want to apply for redress.
In the U.S., travelers can submit a request through the DHS Traveler Redress Inquiry Program (DHS TRIP). This allows you to:
Clarify identity issues
Correct errors in government databases
Reduce future screening complications
After approval, you’ll receive a Redress Control Number. Adding this number to future reservations can help prevent repeated misidentification.
Does SSSS Affect Global Entry or TSA PreCheck?
If you’re enrolled in TSA PreCheck and receive SSSS, your PreCheck benefits will not apply for that flight.
Enhanced screening overrides expedited programs.
