TSA's Rule For Bringing Pepper Spray On An Airplane

It's no secret that the Transportation Security Administration (TSA) has a ton of carry-on luggage rules to know before heading to the airport. And if you're packing for a trip and thinking about bringing pepper spray for personal safety, the answer isn't a flat-out no — but it's not a simple yes, either. According to the TSA rulebook, pepper spray is allowed in checked luggage with specific restrictions. You're allowed to bring one container of self-defense spray, such as mace or pepper spray, in your checked bag — as long as it contains no more than 4 fluid ounces and includes a safety mechanism to prevent it from going off accidentally.

But here's the thing: TSA isn't the only authority on this. Some airlines won't allow you to bring pepper spray in your checked bag, even if the TSA says it's okay. For example, United and Southwest do not allow any self-defense sprays in checked baggage, period. So before you toss that canister into your suitcase, you'll want to double-check your airline's policy — or risk having it confiscated at the airport.

And if you're thinking of bringing it in your carry-on, that's a hard no. Pepper spray is strictly prohibited in carry-on bags, no exceptions. So, if you aren't checking a bag, pepper spray may be one of those items better to buy later than pack in your bag. When it comes to flying, knowing the rules ahead of time can save you a headache and a wasted can of mace.

While TSA does allow limited quantities of pepper spray in checked luggage, many travelers still get tripped up by the details. For example, any self-defense spray you bring in your checked bag can't contain more than 2% tear gas, which some sprays do. If you don't want to try your luck with pepper spray, there are other options for TSA-approved self-defense weapons you can take in checked luggage, such as stun guns and tasers.

It also depends on where you are flying. The Federal Aviation Administration (FAA) notes that international regulations won't allow any sort of self-defense sprays in either carry-on or checked luggage. On top of that, some countries may have laws against specific self-defense items — for example, pepper spray is prohibited in many European countries, such as Iceland, Greece, and Ireland. It's also illegal to possess in the U.K.

So, while the TSA might give you the green light, you'll still want to do your homework before flying with any kind of self-defense spray or other questionable items. If you're searching for a TSA-friendly self-defense option, this SABRE pepper spray and pepper gel should pass the TSA requirements.
