Whether you're flying within the country or heading abroad, this guide will help you understand what's allowed and how to stay safe.

TSA Guidelines: Can I Bring Pepper Spray in Carry On?

Let's get right to it:

No, the TSA (Transportation Security Administration) does not let you bring pepper spray in your carry-on bag.

There is no way you can fly with pepper spray in your carry-on.

Mace, pepper spray, and other self-defence sprays are dangerous compounds and are not allowed in the cabin of an aeroplane.

Why?

People on board could misuse or throw away these things while flying, which could be dangerous for everyone.

That's why you should look up things like

• can I fly with pepper spray in carry on

• carry on pepper spray

• Can you bring pepper spray in your carry-on

You will always get the same answer: not allowed in carry-on.

Can You Bring Pepper Spray in Checked Luggage?

Yes, but only if certain circumstances are met.

TSA lets you bring one (1) container of pepper spray in your checked baggage, however the container must

• Weigh 4 ounces (118 ml) or less

• Have a safety feature that stops inadvertent discharge

• Not have more than 2% concentration of tear gas (CS gas)

Also, airlines can ignore TSA guidelines.Some places don't allow pepper spray at all, even in checked bags.

Before you pack, verify with your airline again.

Airline Policies Vary—Don’t Assume It’s Allowed

Some airlines don't let you bring pepper spray on board, even if the TSA says you can check it.

Some examples are

• Delta Air Lines: Not allowed in either checked or carry-on luggage

• American Airlines: Not authorised anywhere

• Southwest Airlines: May let you bring checked bags, but check first

So if you're still not sure if you can bring pepper spray in your carry-on, keep in mind that the TSA says no and your airline might say no to checked bags as well.

What About International Flights?

The rules of pepper spray can be very different in other countries.

In certain places, it's against the law to carry pepper spray at all. In other places, it may be quite limited or require a licence.

A brief look:

• In the UK, it's against the law for civilians

• Canada: Only legal in some forms, like bear spray

• Japan, Australia,  New Zealand: Often limited or not allowed

• Germany , Switzerland: Legal with conditions

So, even if your pepper spray gets through TSA and your airline's restrictions for checked luggage, you could still get in problems with the law when you get there if it is not allowed.

Final Thoughts

If you're still wondering, "Can I bring pepper spray in carry-o?" the answer is no. TSA guidelines say that you can't bring pepper spray in carry-on baggage.
