Flying can be hectic, and spotting “SSSS” on your boarding pass may add to that stress. These four letters stand for Secondary Security Screening Selection, meaning you’ve been flagged for extra checks before boarding. While it can be inconvenient, it’s a standard part of airport security.
The TSA’s Secure Flight program uses information like your name and date of birth to screen passengers. If you’re selected, it doesn’t mean you’re in trouble—many travelers are picked at random or due to travel patterns. The goal is to enhance security and ensure safer flights for everyone.
Being selected means you may undergo more thorough screening, such as additional pat-downs or luggage checks. This process usually happens at the gate, so it’s helpful to arrive a bit earlier than usual if you see “SSSS” on your pass.
To make the process smoother, avoid bulky clothing and pack light on electronics. Knowing what “SSSS” means can help reduce surprises and keep your travel experience as stress-free as possible.
