Flying is still the fastest and most convenient way to travel, but let’s be honest—airport security can be stressful. Between removing your shoes, separating liquids, and double-checking your bag, it’s easy to feel overwhelmed. To make things smoother, the TSA (Transportation Security Administration) updates its list of prohibited items regularly. Their newest update for 2025 includes some surprising additions you’ll want to know before your next trip.
What’s New on the TSA Prohibited List?
One of the biggest changes is the ban on cordless hair straighteners and curlers that use lithium batteries or butane gas. These items are now prohibited in carry-on luggage because:
-
-
-
Lithium batteries can overheat and catch fire.
-
Gas cartridges may explode due to cabin pressure.
-
-
Another key addition is vaping devices. While you can still bring them in the cabin, you can’t pack them in checked luggage, and of course, you can’t use them during the flight.
High-capacity power banks are also restricted. Their size and energy density make them risky, as overheating in a small space can trigger dangerous fires.
TSA Rules That Haven’t Changed
Some rules remain the same:
- Liquids, gels, and aerosols are still limited to 100 ml per container in your carry-on.
- Sharp objects (knives, scissors over a certain size, etc.) are prohibited in the cabin.
- Firearms are only allowed in checked luggage, and only if they’re declared and properly stored.
These long-standing regulations are all about preventing potential hazards mid-flight.
Why Are These Items Dangerous?
It all comes down to one word: fire.
-
In 2024, the FAA recorded 39 incidents linked to lithium batteries on commercial flights.
-
Vaping devices and gas-powered tools carry risks of leaks or accidental ignition.
-
On a plane, there’s little room for error. Even a small fire can put hundreds of passengers in danger.
The TSA’s strict rules may feel inconvenient, but they’re designed to protect everyone onboard.
How to Avoid Issues at Security
Want to breeze through TSA without drama? Here are some quick tips:
-
Check your luggage at home before heading to the airport.
-
Follow the liquid rule: 100 ml per container, all in a clear plastic bag.
- Remember the battery rule: If it has a lithium battery, carry it in the cabin. Don’t pack it in checked luggage.
- When in doubt, ask: Use the TSA website or the AskTSA tool on X (Twitter) for quick answers.
If you’re unsure whether to pack something, the safest choice is to either keep it in your cabin bag (if allowed) or leave it at home.
The TSA’s goal isn’t to make travel harder—it’s to keep passengers safe. Fires or accidents mid-flight are far more dangerous than a few extra minutes at security. By knowing the rules and preparing ahead, you can avoid surprises and travel with peace of mind.
