Five reasons why you might be stopped at airport security as triggers aren't always random

Traveling across the world can bring joy and satisfy your craving for wanderlust, but before you strut your stuff on a white-sand beach, you have to tackle the dreaded airport security.

US airlines recorded a whopping 862.8 million passengers on domestic and international flights last year, as per Statista.

In further statistics released earlier this year, the Transportation Security Administration (TSA) performed an average of 2.35 million safety checks in US airports in 2023, which is quite a step up from the 925,000 in 2020.

If you’ve ever had your hand luggage flagged before then you’ll be aware how arduous the process of eventually being given the green light can be.

But your basic airport security isn’t the only barrier between you and your destination - sometimes you may be selected to undergo further examination.

In February, Explore.com detailed five of the main reasons why you may find yourself ushered into a room by TSA agents, who are just following protocols to maximize your safety.

These include exhibiting suspicious behavior, having a dud electronic device in your luggage and sharing the same name as a wanted person.

Sceptical travel plans

One of the reasons why you may be stopped and searched thoroughly at airport security is because officials are dubious regarding your trip itinerary and/or travel methods.

These suspicious travel patterns include booking flights at the last minute and purchasing a one-way ticket without any clear return plan to the country you left.

Explore also writes that short trips to faraway lands may raise eyebrows as well as embarking on unnecessary connections, especially across countries which the US has political tensions with.

If your boarding pass is printed with ‘SSSS’ on it, then this could indicate you’ve been chosen as a ‘Secondary Security Screening Selectee’.

This is a US airport security measure which sees particular passengers going through more intensive screening processes and potential pat-downs.

Behavioral detection

If someone is acting strange in the airport and is exhibiting habits the TSA considers part of its so-called ‘secret behaviour checklist’, then they may be hauled in for questioning, according to The Intercept.

The publication writes that involuntary behaviors that suspicious travelers exhibit include yawning, whistling and excessive blinking.

Non-verbal cues like excessive sweating and fidgeting are also considered red flag conduct.

Agents are also likely to check up on those who are talking in an ‘excessive, distracting or otherwise suspicious manner', says Explore.

Surnames and false positives

The Transportation Security Administration (TSC) states that the FBI maintains a federal ‘No Fly List’ as part of a small subset of the US government’s Terrorist Screening Database.

It’s understood this program works by flagging the names of known or suspected terrorists.

Unfortunately, if you share the same or a familiar moniker, you may find yourself being hauled in for extensive searching.

This is called a ‘False Positive’ and airlines and securities are aware of the challenges and damage they can bring about.

Explore writes that providing full names, middle names and dates of birth when booking your flight can help to reduce the likelihood of an extra grilling by officials.

Physical and electronic triggers

If you’ve ever placed your hand luggage through the X-ray machine, only for a handler to flag the contents, then something in your bag may have acted as a trigger.

Physical triggers such as prohibited liquids and weapons in a passenger’s luggage can cause a stop-and-search attempt.

Backscatter passenger scanners may also pick up physical security threats such as explosives or drugs on a person’s body.

Electronic triggers are characterised as electronic devices that either fail to turn on or show clear signs of tampering.

Like physical triggers, possessing these materials could prompt you to undergo additional inspection processes.

Random checks still do happen

Sometimes there is no method to the madness when it comes to being subjected to additional security checks.

Passengers are often randomly selected to undergo further scrutiny by officers, with one reason being it makes throwing off a possible aviation threat possible.

If you want to avoid becoming one of these unlucky bunch, it’s suggested that you have up-to-date travel documents.

You should also make sure your name, age and other intimate details are displayed correctly on your boarding passes.
