It’s Official:This Airport Mistake Can Keep You from Flying in the United States

This summer, a mistake at the airport could cost you more than you think, and many passengers are already experiencing it

Traveling by plane should be exciting. But if you don't pay attention to the new TSA warnings, your adventure could end before you even take off.

The rule that many keep ignoring

TSA has had enough. This summer, with millions of passengers passing through security checkpoints, travelers' behavior is under scrutiny.

What's prohibited? Any kind of aggressive attitude: insults, shoving, threats, or simply treating agents poorly.

The result? Fines of up to $17,062, expulsion from the security checkpoint, loss of access to TSA PreCheck for several years, and even possible criminal charges.

Yes, even if it seems extreme, it has already happened. According to TSA, in 2024 there were more than 1,200 cases of unruly passengers. It's not just a problem for the staff: every incident delays the line, causes luggage to pile up, and can affect dozens of people who aren't at fault for anything.

What could cost you the flight (and much more)

Many passengers don't know there are serious consequences, even for what they consider "just a simple complaint."

Here are some real examples:

  • Bringing a loaded gun to the checkpoint: up to $15,000 fine.
  • Telling an agent "you'll regret it": $4,500 fine.
  • Banging on a table or pushing a security cone: could lead straight to arrest.
  • Causing a scene in line: TSA PreCheck suspension for 5 years.

Additionally, if bad behavior continues on the plane, the FAA can impose additional penalties of up to $37,000 per incident. All that for losing your patience for a few minutes.

The impact on other travelers

When a single person causes problems, the effect is immediate. The line stops, screenings are repeated, and wait times double.

TSA has already reported delays due to prohibited items such as:

  • Sunscreen in large bottles
  • Weighted training ropes
  • Machetes bought as souvenirs
  • Toy grenades or decorative replicas

Even items like large coffee cups or canned drinks trigger secondary inspections. With more than 3 million travelers per day in July, any small mistake has a big impact.

Courtesy is also security

Even if it sounds like advice from your grandmother, being polite can save you a lot of trouble.

According to TSA data, polite and prepared passengers help lines move up to three times faster. TSA PreCheck lines, for example, last less than 10 minutes. Regular lines, more than 30 during peak hours.

A "thank you" or a "good morning" not only improves the atmosphere: it saves you time, prevents unnecessary screenings, and helps everyone.
