Importantly, receiving the SSSS code does not mean you are suspected of wrongdoing. In many cases, the selection is random. In others, it may be triggered by factors such as:
Booking a ticket at the last minute
Flying internationally
Incomplete or inconsistent reservation details
Sharing a name similar to someone on a watchlist
Even frequent flyers with spotless records can occasionally be selected.
What Secondary Screening Involves
Passengers marked with SSSS undergo more thorough checks than standard screening. This may include:
Detailed hand inspections of carry-on items
Extra scanning or swabbing of electronics for explosive residue
Closer examination of personal belongings
Enhanced identity verification
