If properly planned, taking a flight is usually a straightforward experience - but four letters could throw a spanner in the works.
A travel expert has taken to social media to warn flyers of a certain code that you "never want to see" on your boarding pass before take off. According to TikToker @laxtoluxury, if you see "SSSS" printed on the document, you could be in for extra security checks.
The acronym stands for “Secondary Security Screening Selection", meaning airport officials will likely examine you for additional security breaching possessions through a pat down. It also means that your all bags could be opened up and swabbed for explosive residue.
