When you’re packing for a flight to another country, or taking a domestic flight during a vacation, the last thing you want is to run afoul of the law by attempting to take something illegal on the plane.
Some prohibited items on airplanes are quite obvious, like loaded firearms and explosives. However, others may not be. It’s easy to accidentally overlook the rules when packing a souvenir for a loved one. The next thing you know, your item is confiscated, and you’re forced to pay a sizable fine.
To avoid this, the Transportation Security Administration (TSA) has published a list of prohibited items that cannot be taken onboard an aircraft, along with the fines you could pay when you’re caught. Pay attention to this list, and leave the following items at home.
Prohibited Items to Take Through TSA Security or in Carryon Bags
- Flammable liquids – This includes liquid or gel fuels such as gasoline, turpentine, paint thinner, lighter fluid, and cooking fuel. The max penalty for attempting to board a plane with a prohibited flammable liquid is $2,250.
- Axes, hatchets, and knives – Do not attempt to board a plane with any sort of axe, hatchet, bow and/or arrow, icepick, ice axe, switchblade, butterfly knife, double-edge knife or dagger, meat cleaver, saber, sword, foil, machete, or throwing star. If you’re caught, you could pay a fine of $2,250.
- Non-firearm weapons – These include BB guns, pellets guns, flare and starter pistols, realistic firearm replicas, inert firearms, spear guns, stun guns, cattle prods, or other devices that produce electric shocks. The fine can be up to $2,250.
- Explosives – It may seem obvious, but never attempt to board a plane with blasting caps, dynamite, more than 10oz of gunpowder, hand grenades, plastic explosives, or any other high explosives. The penalty can be up to $14,950 plus a criminal referral.

You are permitted to pack an unloaded firearm into a checked bag, but you are required to declare it with the airline.
