• There is a jar for each person.
• It can hold up to 4 ounces (118 ml).
• Something must be built into the container to keep it from going off by accident.
• Not even checked bags can hold it.

Even a small discharge could compromise the safety of passengers and crew.

Rule	Checked Luggage	Carry-On Bag
Allowed Quantity	1 container, ≤ 4 oz	0 (not permitted)
Safety Mechanism	Mandatory	Not applicable
International Flights	Depends on destination law	Prohibited worldwide

This table clears up the confusion. So yes, can you check pepper spray on a plane? Yes, but always in checked luggage.

Is Pepper Spray Allowed on Planes Carry On?

A frequent question is ‘’is pepper spray allowed on planes carry on?’’ The rule is very strict: no. Passengers may not bring pepper spray inside their cabin luggage.

Reasons for prohibition include:

• One reason for the ban is that it could hurt people if it is accidentally set off.
• Leaks could happen if the pressure inside the car changes.
• A person could intentionally abuse it while in the air.

These people will take away your FightSense spray even if it has a strong safety lock if they find it in your carry-on bag. In this case, airlines care more about the safety of the group than the safety of the person.

If you ever wonder if you can bring pepper spray on a plane, remember that you can't. It's only allowed in the bathrooms.

Do You Need a Permit to Carry Pepper Spray?

Now let's talk about something else very important: do you need a permit to travel with pepper spray? There is no need for a special pass to bring pepper spray into the US as long as you follow TSA rules.

When you look at the world as a whole, though, things look different. Pepper spray is seen as a tool in many places, not something that keeps you safe.

Examples:

• UK: It's against the law in the UK unless you have permission.
• Germany: It's okay, but only for attacks on animals and it has to be clearly marked.
• Australia: Not usually allowed, but sometimes allowed.
• Canada: You can't use it for personal reasons.

If you're going to another country, find out if you need a pass to bring pepper spray with you. You might get a fine, have your things taken away, or even go to jail if you don't do this.
