Help! What does this SSSS stamp mean on my boarding pass?

SSSS — behold the four letters that you don’t want to see on your boarding pass. If you find the Secondary Security Screening Selection — SSSS stamp on your ticket, you should know that the TSA agents will be treating you to an extra-special and in-depth security screening.

Lucky you!

But who selects passengers for this additional form of screening? After Jo Freeman’s unpleasant, close encounter of the TSA kind, she wants to know.

Finding SSSS on her boarding pass

Jo says that on her flight home from a trip to Spain, American Airlines branded her ticket from JFK to Washington DC with the dreaded SSSS.

“The TSA agents took me for a full body scanner, where I stayed for a few minutes. Next followed a light patdown, then a full-body pat-down,” she recalled. “That full-body patdown was indeed overkill. So was the luggage search where I was told ‘don’t touch!’ even after the TSA agents were done searching my stuff.”

When Jo asked about her Secondary Security Screening Selection, she says the TSA agent told her that the airline had chosen her for the special treatment. And so, once home, Jo directed her anger at American Airlines. She sent her complaint letter straight to the CEO. And then, she contacted our advocacy team for additional guidance about the SSSS stamp.

“I want to know why American Airlines selected me to be a ‘house guest,’” Jo asked me. “This meant I spent over an hour being ‘searched’ by the TSA. At age 72, I don’t need this kind of strain. If I can’t prevent it, I may just not fly again.”

Is the SSSS stamp dictated by the TSA or by American Airlines?

While it may be true that American Airlines printed the SSSS on Jo’s boarding pass, it’s not correct to say that the airline picked her for the additional screening.

Although the SSSS passenger selection criteria remain somewhat mysterious, the airlines do not determine which travelers are selected.

The TSA’s Secure Flight Program, which was developed to combat terrorism in this post-9/11 world, determines who gets the SSSS stamp.

Secure Flight is a risk-based passenger prescreening program that enhances security by identifying low and high-risk passengers before they arrive at the airport by matching their names against trusted traveler lists and watchlists.

And, of course, citing security concerns, the TSA says it can’t reveal the specific factors that lead to a passenger being targeted for the SSSS stamp. But it appears that there are some traits common to passengers who are selected for this specialized attention.

SSSS designated travelers are often traveling on one-way tickets, purchase their flights at the last minute or are flying to unusual, high-risk (for terrorism) destinations. Other passengers report having similar names to persons who appear on watch lists.

Are you on some type of watch list?

The SSSS stamp can also show up completely randomly.

However, if you receive an SSSS stamp on your ticket more than once, you are likely on some watch list.

Jo says that she is not a frequent traveler and that this has never happened to her before. And after she made it onboard her flight, she began to think about what would have happened if this thorough search had caused her to miss her flight.

“Would I have any rights if that had happened? Would I have just been stuck in JFK?” she asked me. “Does TSA even care if you miss a flight?”

In a word: No.

These airport security measures are meant to protect travelers and to prevent terrorism.

The mission of TSA’s Secure Flight Program is not to ensure that passengers make their flights. Its purpose is to make sure that no one is allowed onboard an aircraft who may be a safety risk.

And the Department of Transportation has no rule that would compel an airline to compensate a traveler for a missed flight in these circumstances. So if you needed another reason to get to the airport well in advance of your flight, this is it.

Preplanning for the SSSS experience

There isn’t any way to know ahead of time if you will have the SSSS stamp on your boarding pass. Of course, if you frequently see the SSSS stamp on your ticket, chances are you will continue to receive the designation. And if you get a message that you can’t print your boarding pass from home, you may be in for the full TSA search experience.

Travelers report that these extra-long screenings can last from 30 minutes to an hour. The TSA will examine and re-examine everything that you are carrying. And, as Jo reported, a full-body pat-down will likely occur.

American Airlines responds

American Airlines responded to Jo’s complaint about the SSSS stamp by explaining:

As you may know, federal legislation created a government agency, the Transportation Security Administration (TSA), which assumed civil aviation security functions and responsibilities, including passenger screening at the security checkpoints (departure gates). The airlines are therefore, no longer responsible for checkpoint screening as it is now handled by the TSA. Accordingly, the TSA is also responsible for reviewing and responding to all claims or complaints involving the security checkpoints, including the incident you have described.

American Airlines

American’s response did not assuage Jo’s concern about her possible SSSS branding on future flights.

Next step: File a complaint with DHS-TRIP

As Jo believed that she was unfairly targeted, I recommended that she file a complaint with The Department of Homeland Security Traveler Redress Inquiry Program (DHS-TRIP).

DHS TRIP is designed specifically to help travelers improve their travel experience and correct inaccuracies in government records that may contribute to difficulties when traveling. Security procedures and legal concerns mandate that we can neither confirm nor deny any information about you that may be within federal watch lists; we also cannot reveal any law enforcement-sensitive information.

Department of Homeland Security explaining the purpose of DHS-TRIP

As the above paragraph indicates, Jo will likely never know what triggered the SSSS stamp on her boarding pass. It may have been a random fluke — or maybe not. But by filing a formal inquiry with DHS TRIP, she hoped to get some clarity.

Department of Homeland Security (DHS TRIP) responds

DHS-TRIP completed a thorough investigation of Jo’s complaint. Although the agency did not give her specific information — the response seemed to lean toward an error in Jo’s records.

DHS has researched and completed our review of your case. DHS TRIP can neither confirm nor deny any information about you which may be within federal watchlists or reveal any law enforcement sensitive information. However, we have made corrections to records that our inquiries determined were necessary, including, as appropriate, notations that may assist in avoiding incidents of misidentification.


I’m happy to report that Jo’s next trip was free of any special attention from TSA. And her boarding was free of the SSSS stamp. (Michelle Couch-Friedman, Consumer Rescue)

Before you go: What’s the opposite of finding an SSSS stamp on your boarding pass? The TSA PreCheck stamp, of course! But here’s what happens if you get in that line without the TSA PreCheck stamp.

OMGoodness……this was really educational for myself. As much as I travel I never before heard of this special stamp, that in my case would stop me from flying. I’m too sensitive to accusations and extra special attention ( sarcasm), when I know I wouldn’t do anything to jeopardise my own or anybody elses security. I hope I can sleep tonight after reading this.

Don’t worry, Maria. At least you’ll know what it is if you ever see it. 🙂


What a horrible experience! I knew all about SSSS but had no idea that it could take up to an hour to ‘search’ a pax. And there’s absolutely nothing anyone can do about it. It’s stuff like this that makes experienced travellers arrive early for their flights. A pat-down and search of your carryon shouldn’t take more than 5 minutes … especially if the SSSS victims are chosen randomly. It does sound like she was ‘mistaken’ for someone on a list somewhere, so maybe she could have been detained 10 minutes. Two officers can search and re-search her items plus do a pat-down in that time. This was really callous treatment of an American citizen … a country where one is assumed innocent until proven guilty, after all.


I got two SSSS in a row on pretty normal trips – both returning from western Europe to the U.S. Since then I’ve had trips without it, but it’s nice to have the redress program in my back pocket. Do you know how long the investigation/resolution took?

Michelle Couch-Friedman

Hi Tony, It took about 3 months. But I believe the website advises that it can take up to 6 months to receive a determination.


Strange things happen with boarding passes sometimes. On one trip to a foreign country, I got a random gift of a precheck pass on my way out and SSSS on the way back. No one knew why. The TSA guy who searched me said it sounds like random luck twice, cancelling each other.

I received this stamp once at Long Beach Airport, which involved a search in a voting-machine type booth. No privacy. Shoes and socks off, shirt off, down to boxer shorts. I have had security clearances at various levels since the 70s and an FBI file (for background checks) since 1964. No explanation.

Once on board the plane, a few passengers around me were sympathetic. Others demanded to know from the flight attendants why I was allowed on.

I had purchased a last-minute, one-way ticket. That’s my best guess.


Wow… not good indeed. And what happens if they cause you to miss your flight? Tough Cookies?

I got SSSS while coming back to the States by the American Airlines, the first week of July 2023. Until I got it on my boarding pass I hadn’t known what did it mean, I had googled it after the screening. My flight was from Casablanca to Madrid, to Dallas then Fresno. Although I am American citizen I am sure I was selected because of my middle eastern back ground. They did not find anything illegal or against any rule. Completely unfair selection. Even the TSA agent or officer at that metal X ray gate was rude and raised her voice at me to go through the gate twice (although it did not peep). Of course she did that because of my middle eastern feature and because I was escorted by another TSA because of the SSSS.
I think American Airlines had a role in my selection because of my name (Osama/Usama) and my birth place in the passport. I travelled many times with Turkish airlines, Lufthansa, Ethad/Emirates never had that SSSS. Definitely I will avoid using that airlines again specially for international trips.

I don’t like is having my luggage searched! I travel to Colombia a couple times a year. And two or three times I’ve had my luggage searched in Atlanta on my way back into the usa. They just take everything out and throw it all over the place. Then you got to just shove it all back into your suitcase. I also had a couple of bottles of medication. They just dumped the pills out all over in the suitcase, didn’t even put the lids back on them. And I had to pick them all up.
