But SSSS stands out because it isn’t something most passengers see regularly.
And because security screening is involved, people naturally wonder whether the letters indicate a problem.
The uncertainty can make the situation feel much worse than it actually is.
If you see SSSS, take a breath.
Read the instructions.
Ask an airport or airline employee where you need to go.
Then follow the screening procedures.
There’s no benefit to panicking.
## Will You Still Be Allowed to Fly?
Being selected for additional screening does not automatically mean that you won’t be allowed to board your flight.
The screening process has to be completed before you can proceed.
If the additional screening takes time, that’s why arriving at the airport early is especially important.
A passenger who arrives at the last minute may find the situation much more stressful.
If you have an SSSS designation, give yourself extra time.
You may need to wait while security personnel complete the additional procedures.
You may also have to wait for your belongings to be examined.
The exact process depends on the airport and circumstances.
## What Happens During Secondary Screening?
The experience can vary.
You may be asked to undergo additional screening of your person and belongings.
Security officers may inspect your carry-on items more carefully.
You may be asked questions about your trip.
Your luggage may be examined.
The process can involve several steps, depending on the circumstances.
It is understandable to feel uncomfortable when your belongings are being inspected more closely than usual.
But remember that security personnel are performing their assigned duties.
The best strategy is to remain polite and cooperative.
If you don’t understand an instruction, ask for clarification.
There’s nothing wrong with saying:
“Could you please explain what I need to do?”
## How Long Does It Take?
There isn’t one universal answer.
