Can I bring pepper spray on a plane? (Asking for a friend)

Can I bring pepper spray on a plane? (Asking for a friend)

I was sitting around the other night reading all about the latest air rage incident, and a peculiar thought popped into my head: can I bring pepper spray on a plane?

I mean…a friend asked me this. I (a true manly-man) would never admit to needing assistance to bring down a hallucinogenic 290 lb guy on meth who is attempting to punch a hole through the fuselage at 37,000 feet.

Anyway, I decided to do a bit of research about pepper spray and airline travel. Here’s what I found:

First of all, it’s perfectly legal to carry pepper spray in all 50 states. There’s nothing illegal about that. However, the TSA prohibits passengers from bringing it with them inside an airplane. Which is an unfortunate thing if I (I mean my friend) ever comes face to face with a lunatic hell-bent on bringing the plane down in blaze of drug-induced glory.

That being said, there is a way to take pepper spray with you on airplanes. Read on to find out how…

How to bring pepper spray on a plane (without getting arrested)

Whether you’re a first time flyer or not, most people are surprised to learn that bringing pepper spray on a plane is simple (and legal) as long as you know what you’re doing. The following is a step-by-step guide that will explain how to make sure your pepper spray doesn’t get you flagged at the gate. Or worse.

Step one: choose the right pepper spray

Airlines only permit passengers to carry certain types of pepper spray on board (in the cargo hold only – not as a carry on item). According to TSA regulations, canisters should be smaller than four fluid ounces and must have some sort of safety mechanism built into the design. Otherwise, airlines run the risk of an accidental discharge.

In a cabin filled with recirculated air, a discharge of pepper spray would cause severe discomfort and even respiratory distress in sensitive passengers. It’s important for the health and safety of everybody onboard that any mace you back is capped and fastened before packing. You may even want to seal it in an airtight bag just to be safe.

Thinking how thankful my friend must be knowing that I did so much research about bringing pepper spray on airplanes.

Airlines also prohibit any pepper spray that contains more than two percent tear gas, regardless of size. Unlike pepper spray, which is composed of natural components, tear gas spray contains harsher man-made chemicals, such as CS or CN. It tends to reach farther and cause more serious side effects, which is why tear gas sprays are banned by most airlines.

Step two: pack correctly

While pepper spray is legal to take on a plane, you can’t keep it in your carry-on luggage. A canister of mace left in a purse, suitcase, or backpack may discharge into the cabin, disrupting both passengers and staff. It may even force an emergency landing, especially if it causes any medical emergencies.

It’s easy to forget mace in your purse or backpack, so always be sure to take special care to store it properly before traveling. Make a point of adding it to other forbidden items, such as sharp objects or large containers of fluid. This way, you’re less likely to get stopped at the security checkpoint and delayed for your flight.

And don’t think you’ll be able to to outsmart the TSA agents. Just as how airport scanners can detect drugs, they can easily detect mace and pepper spray as well.

You must pack any mace you bring on your trip in your checked luggage (to be stowed in the cargo hold). The compartment is sealed from the cabin so that if there’s an accidental discharge, it won’t end up causing harm.

Maybe now that you know that bringing pepper spray with you inside the cabin isn’t an option, you’ll take your gym membership more seriously.

This rule is enforced for the safety of cabin crew and other passengers. Airlines don’t want mace anywhere an unruly or hostile traveler (such as a prisoner being escorted by law enforcement) could easily reach it. Yes, transporting prisoners on planes is more common than you might think.

On a related note, have you ever wondered how to spot an air marshal? One of the easiest ways is to look for someone scanning the cabin for passengers with prohibited items (such as pepper spray). Even if you somehow manage to bring pepper spray on a plane with you, it would be easy for an air marshal to spot – and you could get in serious trouble for it.

Finally, even though you and your fellow passengers are safe from mace and pepper spray stored in the cargo hold, it’s still good practice to seal the canister in an airtight and watertight bag or container. It can be hard to get the stain and smell of mace off of clothing, and so you may end up with a bag full of unusable luggage.

Pepper sprays and accessories for travel

Flight-safe alternatives to pepper spray

If you’re not sure whether or not pepper spray is right for your travel situation (for example, it’s illegal in some European countries, but not all), it’s important to know that there are other flight-safe self-defense options.

Tasers and stun guns are also fine to pack in your checked luggage, and they don’t pose a risk of discharging irritating spray into the air. However, just as with pepper spray, the legality of carrying a stun gun may be questionable in some foreign countries. Do plan ahead!

There are huge consequences to getting caught, and if you ever find yourself in that situation, you might want to start asking other questions such as: can I fly with a warrant?

You can find other, non-irritating self-defense sprays that are legal throughout most of the world (ones which may even be acceptable to pack in your carry-on). Most of these contain a dye or foam used to mark or incapacitate an attacker.

At the very least, you can always carry a safety whistle or personal alarm on your person. Both of these are designed to emit a loud noise to either scare away your attacker or attract help in an emergency. Most of these devices are airplane-safe, though you should take care to make sure that they don’t go off during your flight. That would be embarrassing.
