No—seeing SSSS on your son’s boarding pass does not by itself mean he is in trouble. It means the passenger has been selected for Secondary Security Screening Selection, so airport security will carry out additional checks before he boards.
What should he expect?
The additional screening can include:
- A more thorough inspection of his carry-on luggage
- Swabbing his hands or belongings for security screening
- Additional questions
- Additional screening of his person, potentially including a pat-down
- Screening at the normal checkpoint or, on some international flights, near the gate
- It can take longer than ordinary security, so he should allow extra time and follow the officers’ instructions.
Why did he get SSSS?
The exact selection criteria are not publicly disclosed. Importantly, a recent U.S. government report based on TSA data says that the vast majority of SSSS designations in recent years have resulted from random selection.
So the four letters do not automatically mean he has done anything wrong, is under arrest, or is going to be denied boarding.
What should you tell him right now?
You can reassure him:
“Don’t panic. SSSS means extra security screening. Cooperate with the officers, allow extra time, and follow their instructions.”
If this is happening on a U.S.-related flight, that’s especially consistent with the TSA’s Secondary Security Screening Selection system.
If he is already at the airport today, the most useful thing is simply to arrive at the security area early and let the airport staff handle the additional screening.
