What is SSSS on your Boarding Pass for International Flight ? What does it mean ?

In airline travel security world, SSSS is an acronym for ‘Secondary Security Screening Selection’…sounds like an interesting acronym with same 4 letters that I have never seen before…anyways, the backend Security Systems (especially airport security) of US assess the passenger profile and issues this security rating for secondary screening.  Basically, it means that the security systems determined that based on your profile, travel history, and others it has selected you for additional security screening and tagged your boarding pass with ‘SSSS’. Some say, system has randomly selected you, but you know that is a nice way of putting it on the system…it may very well be, but you know the truth !

Why are you given SSSS by the Airport Travel Security System ?

No one will clearly tell you the reason for you getting SSSS on your boarding pass. But, some of the common reasons for getting SSSS are based on the premise that there was something unusual in your travel pattern, your ticketing, or your overall profile such as below :

  • Booking of one-way international flight tickets
  • Traveling from a high-risk country

  2. I had an SSSS on my boarding pass from Dublin to USA and almost missed my flight which had only an hour of connection. Being a senior of 68 years of age and having to rush/run to get to my connecting flight, I was ready to pass out on arrival at the gate and to my seat. In addition to that I did not get my luggage on arrival at Ohare ( Chicago). A very exhausting and frustrating experience in all of my travels considering that I do a lot of medical / disaster missions internationally and domestically.

  3. This article was most revealing.

    I had SSSS on my boarding pass out of Ecuador to the US. I was taken off the flight and searched, both my bags and myself. I understand that they searched my seat while I was outside the plane. During the search my boarding pass for my domestic flight from Miami to home did not have SSSS on it, but was miss placed during the search. I went to a Kiosk to print off another boarding pass. This time the SSSS appeared. When I got to secured TSA pulled me aside and I went through the same procedure again. This time it took 45 minutes with a full body search.
    I travel a lot domestically and 45 minutes will definitely effect my making the flight in the future.
