Secondary Security Screening Selection (SSSS) is one of the many security measures implemented by the Transportation Security Administration (TSA), designed to identify passengers who require additional screening on flights departing or arriving in the U.S. - domestic as well as international flights - including domestic flights with multiple connecting flights.

Why You Never Want to See SSSS on Your Boarding Pass?

If the letters "S" appear on your boarding pass during regular security screening, TSA officers may conduct further checks on you or your luggage. A security screening and search system (SSSS) typically involves an agent requesting you to unpack all personal and carry-on bags for manual search, test electronic devices and undergo pat-down searches - these procedures may last several minutes to half an hour or longer.

The selection criteria for SSSS are kept secret to prevent security threats from adapting and evading detection. Anecdotally, passengers with unique travel patterns, such as one-way international tickets or traveling to countries considered high-risk by the U.S., may be more likely to receive this designation; alternatively, TSA may assign this label randomly.

If selected for secondary security screening (SSSS), an indication may be the inability to check in online with an airline app or website, in which case in-person check-in at the airport will be necessary for various reasons - which could potentially mean secondary screening, will be conducted on you.

If you are selected repeatedly for SSSS, applying to the DHS Traveler Redress Inquiry Program (TRIP) could be worthwhile. TRIP offers an opportunity for removal from undisclosed watch lists as long as no imminent security threat is posed.

Traveling Frequently to "high-risk" countries for visits with family may trigger increased scrutiny; once accepted into TRIP, you'll receive a Redress Number which could help minimize issues at airport security.

Additional security screenings may be necessary beyond just having an SSSS designation. For instance, if anything suspicious is discovered during bag scanning, they could be pulled aside for manual search.

Random secondary screenings can occur at any stage during security processes - like passing through a body scanner or metal detector - where additional screening may involve swabbing your hands for explosives and conducting publicly or privately pat-down searches.

"TSA agents may select passengers based on suspicious behaviors," according to Dan Bubb, professor at the University of Nevada Las Vegas and former airline pilot. Both airline personnel and TSA agents receive extensive training in recognizing potential concerns that warrant further examination, particularly those related to drug smuggling or illicit activity.

What Is Secondary Security Screening Selection, or "SSSS"?

Secondary Security Screening Selection (SSSS), an initiative of the Transportation Security Administration (TSA), flags passengers for additional screening before any flight departing or arriving in/through/via the U.S. - includes inbound international flights.

When airport security screening officers encounter these four letters on your boarding pass during regular security screening procedures, they may take additional measures and conduct additional checks - either on your bag or yourself.

As part of the boarding process, an agent will usually request you to unpack all personal and carry-on bags for a manual search by an agent. Your electronics could also be tested (so be prepared to remove their cases first!) before being patted down for inspection. These processes may take two to 30 minutes or more to complete.

Why Do People Receive an SSSS Designation?

No official data on who receives this designation was published - that was intentional, as security threats may become less detectable otherwise.

Anecdotally, it appears the S designation may be awarded more frequently to travelers with unusual travel patterns, such as one-way tickets or travel to countries deemed high-risk by the U.S. It's likely the TSA doles out these designations randomly as well.

If selected, I will appear somewhere on your boarding pass. One indicator that you may have been chosen could be an airline app or website notifying you that in-person check-in will be necessary at the airport - something that could indicate you need to prepare for SSSS.FlyFi is your one-stop travel information shop.

What should you do if my name keeps appearing on my boarding pass?

If SSSS keeps showing up, consider applying to the DHS Traveler Redress Inquiry Program (TRIP). Applying could remove you from any mysterious watchlists -- provided that you don't pose an immediate security threat (traveling frequently to high-risk countries could even when visiting family). Once accepted into TRIP, you will receive a Redress Number which could reduce issues at airport security!

Why might additional security screenings be necessary?

Being labeled with SSSS can initiate additional security processes - from pat-downs, hand swabs, and bag searches. Extra screening measures might become necessary if something suspicious comes up during bag scanning; at that point, your bag will be pulled aside for manual searching.

Random secondary screening may occur at any stage during the security process, typically when passing through a body scanner or metal detector. You could be randomly chosen for secondary screening at any point - for instance, when walking past these devices - potentially having your palms or electronic devices swabbed for explosives and undergoing either public or private pat-downs for explosives detection. Dan Bubb, professor at the University of Nevada Las Vegas and former airline pilot, informed Travel+Leisure (T+L).

Such suspicious behaviors could signal drug smuggling activities; therefore, airline personnel and TSA agents undergo extensive training on recognizing potential contraband.

Conclusions:

SSSS plays an essential part in improving airport security. While its selection criteria remain undisclosed, passengers who repeatedly receive this designation can explore options like the TRIP program to potentially address watch list-related issues.

Understanding why additional security screenings are conducted - for instance, screening out suspicious behaviors and potential threats - helps ensure all travelers' well-being and that they travel safely.
