Holidaymakers are being urged to check their boarding passes carefully before heading to the airport, as a small but crucial detail could cause significant delays or even prevent them from flying.
Experts have warned that a specific code printed on boarding passes – often overlooked by travellers – could lead to extra security checks or denied boarding if not addressed in advance.
What to Look For
The issue centres around a four-letter code known as the 'SSSS' designation, which stands for Secondary Security Screening Selection. This marking indicates that passengers have been randomly selected for additional security measures by the Transportation Security Administration (TSA).
While the system primarily affects flights to and from the United States, British travellers connecting through US airports or flying with American carriers should be particularly vigilant.
Why It Matters
Passengers with SSSS on their boarding passes can expect:
- Thorough hand luggage inspections
- Potential pat-down searches
- Extended security screening time
- Possible questioning by security personnel
Airport officials recommend arriving at least three hours before departure if you've been flagged with SSSS to avoid missing your flight.
How to Handle an SSSS Marking
If you spot the SSSS code on your boarding pass, travel experts advise:
- Remaining calm – it's typically a random selection
- Allowing extra time for security procedures
- Having all documents readily accessible
- Being prepared for detailed questions about your travel plans
While there's no way to remove the SSSS designation once assigned, frequent travellers suggest enrolling in trusted traveller programmes like TSA PreCheck or Global Entry to reduce the likelihood of being selected.
The warning comes as airports experience peak summer travel volumes, with security queues already longer than usual at major hubs across the UK and Europe.
