If you see “SSSS” written on your boarding pass, you may be in for some trouble at the airport.
Boarding passes labeled with this code subject their carriers to extra scrutiny, costing them time and possibly their flight, if they don’t arrive at the airport early enough.
SSSS stands for Secondary Security Screening Selection and it is what the Transportation Security Administration (TSA) uses to mark certain passengers traveling into the United States for extra screening.
Those whose boarding passes are marked with the code report not being able to print their boarding passes at home or from a kiosk at the airport, and receiving a pat down or bag search while going through security. Sometimes SSSS-selected passengers are required to submit more information, such as detailed info on their travel plans.
The TSA claims that passengers given the code are chosen at random by a computer, or by screeners who look for “irregularities” on a person where weapons could be hiding. However, insiders say otherwise.
Also, sometimes a criminal record can get a person on the list, or if you have a history of bad behavior while flying, Weinstein said.
Just because someone has “ssss” written on their boarding pass, however, doesn’t mean they will get extra screening every time. Only those who are put on the “selectee list” will routinely get more inspection.
