17 Items the TSA Absolutely Forbids in Your Luggage
Did you know that on November 26, 2023, the TSA screened more than 2.9 million passengers in one single day? It’s no wonder why security measures are as tight as a fully packed suitcase; that’s how many people are on the move.
Half the battle is knowing what not to bring. You don’t want to be that line-hold guy having your cherished item taken away; an agent confiscates it because it breaks the rules.
To spare you the possible embarrassment and fines, here’s a list of 17 things the TSA bans in your luggage. Get informed, read on, and travel smarter.
Fireworks
Stunning explosions in the sky are not allowed in luggage. Due to obvious safety hazards, the TSA bans carry-on and checked baggage containing fireworks.
If you think, “It’s just some sparklers,” don’t risk it. They are classified as hazardous materials and can cause fires in transit. Leave your pyrotechnics at home if you’re determined to keep your holiday spirit alive.
Compressed Gas Cylinders
You’ll have to wait until you rent tanks for that scuba diving adventure in Hawaii. High-pressure hazards preclude empty or fully compressed gas cylinders.
Rent equipment instead at a certified provider on site. It’s safer, hassle-free, and will fit within TSA’s guidelines.
Items like Axe, Hatchets
Are you planning to camp after landing? That’s fine—but leave your axe out. TSA rules prohibit tools exceeding 7 inches in length in carry-on luggage.
This includes even recreational items like hatchets. The logic? These could be used as weapons. It is essential to consider which tools you will need access to during the flight and which you’ll need access to afterward.
Flammable Liquids and Gels
Flammable objects can now be a significant hazard on a flight; yes, lighter fluids or certain cleaning materials are on the list. According to the FAA, gasoline, turpentine, or paint thinner are dangerous goods.
If you must take flammables to travel with, send them separately. Pro tip: Check your airline’s list of restricted materials to avoid getting caught out.
Hoverboards
Yes, they’re still cool. No, they’re not allowed. Lithium-ion batteries render hoverboards a definite no for air travel. Airlines ban them because lithium batteries explode into fire if they aren’t handled properly.
Alternatively, think about renting a mobility device where you will be. This is true for most airlines worldwide and can’t be a loophole at the airport.
E-bike batteries
TSA prohibits batteries with over 100Wh, such as high-capacity Electric bike batteries. Spare batteries for medical devices like PDAs (personal digital assistants) are also not spared.
Battery failures cause a dozen or more in-flight fires every year. Always check your device specs before flying, or call your airline for confirmation.
Knives (Collectibles, Decorative Knives, Sports Knives, Daggers, Switch Daggers, Balisongs, etc.)
Do you think a pocketknife (which isn’t all that dangerous) or an ornate collector’s piece won’t be a problem? Think again.
Decorative knives, such as dagger-shaped objects made of plastics, are banned from carry-ons, as are full-sized knives of any material. Put them in your checked bag — just be aware that TSA can confiscate anything it deems unsafe.
Self-Defense Items
You don’t have to pack like James Bond before leaving on vacation. Self-defense equipment, such as tasers, pepper spray, and other devices, is tightly restricted or prohibited altogether.
Your intention doesn’t matter here, so keep that in mind. What’s essential are airline policies and federal laws. If you don’t feel safe traveling, buy a whistle or an emergency alert device instead.
Explosives and Blasting Caps
Any traveler carrying these items through security will be in legal trouble. The federal government heavily regulates explosives used for demolition or construction.
Expect lengthy questioning if your item looks suspicious to law enforcement or the TSA. Additionally, do not attempt to bring such materials onto airport property.
Live Ammunition
Have you got hunting plans elsewhere? Proper disclosures are required for your guns and ammunition. All live rounds are prohibited except as an exception to the TSA’s firearms transportation rules.
Ammunition or purpose-built storage certified for airline travel should be kept in its original case. But don’t forget that gun violations can result in fines of up to $14,950.
Gel-Type Candles
Solid wax candles may give off a peaceful vibe, but the gel isn’t a friend of TSA agents because it acts like a liquid. As far as the TSA is concerned, they put them in the same category as liquid items.
That aromatic gel candle that goes into your bag every time; always double-check, as those can be a fire hazard.
Alcohol Above 140 Proof
Do you think it’s harmless to grab your favorite bottle of moonshine in Tennessee? Think again. Because of their flammability, TSA-regulated flights can’t transport liquors with more than 70% ABV.
Travel is smooth if the alcoholic content is kept under 140 proof. Because the high-proof liquids increase burn hazards, they are red flags.
Dry Ice (Over 5.5 Pounds)
Want to keep perishables cool? Dry ice is permitted in small quantities during flights, but more than 5.5 pounds is illegal under the federal code.
Dry ice is risky if improperly managed because every inch past regulation means more CO2 emissions.
Engines or Motor Parts with Fuel Residue
Want to ship rebuilt motors across states? Engine parts with residual oil or stains can be subject to severe fire during transit. More significant parts can be deferred to freighting services entirely.
Large Lithium-ion Batteries
Power banks over the capacity rated by the FAA don’t pair well with cockpit areas, so avoid large lithium-ion batteries at all costs.
Irritating Chemicals
TSA has a strict policy on sprays like bear repellant, mace, and industrial pesticides. These chemicals are the leading causes of irritation and other harmful effects.
Further, if accidentally discharged in flight, they could cause skin irritations and other respiratory infections.
Oxygen and Air Fresheners in Canned Form
Though their compressed gas content might seem harmless—canned oxygen and pressurized air fresheners are on the no-fly list. These items can pose a substantial risk under changing air pressure during flights and could rupture or explode.
