What does it mean when someone receives a ‘SSSS’ on their boarding pass?
If your boarding pass shows 'SSSS', you will undergo an additional security check at the airport. This is a random selection process and does not mean you are a criminal. The selection criteria could be your destination, travel patterns, or incomplete booking details. The US-based system involves a full pat-down, explosive trace swab, and manual inspection of carry-on items.
