If you’re someone who always has your pepper spray in hand (we get it—that’s us too), you might be wondering: Can I bring pepper spray on a plane?
Whether you're heading off to college, visiting family, or going on that much-needed girls’ trip, your safety shouldn't have to stay behind.
Let’s break down what the TSA actually says, what is and isn't allowed, and how to prep before you pack.
Is Pepper Spray Allowed on Planes?
Yes, but with very specific rules—and only in checked baggage.
According to the Transportation Security Administration (TSA):
-
You can pack one container of pepper spray (up to 4 fl oz / 118 ml) in your checked luggage.
-
It must have a safety mechanism to prevent accidental discharge.
-
It cannot contain more than 2% by mass of tear gas (CS or CN).
-
Not allowed in carry-on bags—period.
So basically, if it’s a small, standard personal defense spray and it’s going in your checked bag, you should be good. But always double-check your product label and with your airline before you pack!
All Safely Pepper Sprays meet TSA’s guidelines for checked baggage.
Can You Carry It in Your Purse or Carry-On?
Unfortunately, pepper spray is strictly prohibited in your carry-on.
TSA agents will confiscate it at security, and you could even face fines depending on the situation.
So if you're flying with your everyday carry, make sure to pack it in your checked bag (and don’t forget to re-pack it in your purse once you land!).
Why No Carry-On?
Pepper spray is technically considered a non-lethal weapon, and TSA’s top priority is keeping everyone safe in the air. Even a tiny canister has the potential to irritate eyes, airways, and skin throughout the entire cabin—especially in such a confined space.
If a canister were to accidentally discharge mid-flight, the effects wouldn’t just impact the person holding it—everyone on board could be affected, and it could even force an emergency landing. (Yep, seriously.)
That kind of incident doesn’t just delay your travel plans. It can also result in hefty fines if the pepper spray was traced back to your bag.
So while it’s an essential tool for everyday safety, it’s one you’ll need to pack carefully and check when flying.
A Quick Note on Airlines and International Travel
Even though TSA allows it in checked baggage, some airlines have stricter policies, and many international destinations don’t allow pepper spray at all.
Before your flight, we recommend:
-
Checking your airline’s website for their specific rules
-
Looking up local laws at your destination (we’ve got a full state-by-state guide here for U.S. travel)
Safely’s Tip: Travel Smart, Stay Safe
We know travel can already feel a little vulnerable, especially if you’re flying solo.
While pepper spray can’t fly in your carry-on, you still have options:
-
Bring a personal safety alarm (many are TSA-compliant!)
-
Carry a small flashlight for peace of mind in low-light areas
-
Download safety apps that share your location with trusted contacts
Traveling with your Sidekick?
You can bring your Sidekick with the Strap Grip in your carry-on, as long as you remove the pepper spray canister first.
That way, you’ll still have access to the flashlight and alarm features during your trip.
And as always, trust your gut, stay aware, and don’t be afraid to ask for help if something feels off.
The Bottom Line
Yes, you can bring pepper spray on a plane—but only in checked luggage and only if it follows TSA guidelines. Skip the stress at security and know before you go.
