The rules for bringing toiletries on a plane can be confusing, especially when it comes to deodorant, as it is available in many different types.

You can bring both solid and liquid deodorant on a plane in your carry-on bags.

If it is liquid deodorant, though, the container must not exceed 3.4 oz/100ml.

Roll-on deodorants for example, fall under this classification.  

You can also pack both solid and liquid deodorant in your checked bags with few very limitations.

We take a look at other types of deodorant that include spray, gel, liquid, cream, pastes, roll-ons, and powdered deodorant.

We also cover whether the rules and regulations vary by airline, if you’re traveling internationally, and more.

Can You Bring Deodorant in Your Carry On?

If you want to bring deodorant on a plane in your carry on bags, you need to be aware of the 3-1-1 rule.

TSA’s 3-1-1 rule states that any liquid, gel, or aerosol must be in a container that is less than or equal to 3.4 oz/100ml and placed in a 1 quart resealable bag. This rule applies to each passenger.

This means that spray, roll-on, gel, liquid, cream, and paste deodorant must not exceed 3.4 oz/100ml.

Bringing Solid and Powder Deodorants in Your Carry On

Solid deodorants, such as stick deodorants, as well as powder deodorants, do not have the same restrictions.

There is no limit to the size and quantity of solid deodorant you can bring (as long as you follow the airline’s weight and size restrictions for carry-on bags).

Powder deodorant is also fine. The only thing to know is that if the container exceeds 12 oz/ 350ml, it may require additional screening.

Bringing Deodorant in Your Checked Bag

If you want to pack your deodorant in your checked bags, and it qualifies as a liquid, gel, or aerosol, you need to remember the following:

“The total aggregate quantity per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). The capacity of each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).”

Considering how deodorants usually come in relatively small containers and the fact that you likely aren’t packing a 5-year supply means that this won’t apply to you.

Airline Restrictions for Deodorant

Whether your next flight is with United, Spirit, Southwest, Delta, American Airlines, Alaska Airlines, JetBlue, or any other airline, it doesn’t matter.

The same rules apply.

This means that spray, roll-on, gel, liquid, cream, and paste deodorant must not exceed 3.4 oz/100ml if packed in your carry-on.

Solid deodorants are not limited to the same restrictions.

Bringing Deodorant on International Flights

Again, it doesn’t matter if you’re flying domestically or internationally.

Worldwide, the same rules apply.

So, spray, roll-on, gel, liquid, cream, and paste deodorant must not exceed 3.4 oz/100ml in your carry-on, yet solid deodorants are fine.

How to Bring More Than 3.4 oz/100ml of Deodorant on a Plane

There are only two ways to bring more than 3.4 oz/100ml of spray, roll-on, gel, liquid, cream, or paste deodorant on a plane in your carry on bags.

  • Obtain Prescription Deodorant

TSA allow larger amounts of medically necessary liquids and gels “in reasonable quantities”.

This can include deodorant if it has been prescribed.

The only thing to note is that a passenger must declare the item to TSA officers at the checkpoint for inspection.

  • Buy Deodorant at the Duty-Free

Items bought at a duty-free store once you have passed through airport security do not have to stick to the 3-1-1 rule.

This is because these items qualify as STEB items (secure, tamper-evident bags purchased at the airport).

Buy Travel-Sized Deodorant for Air Travel

In our opinion, it’s a good idea to buy travel-sized items when flying, whether that be deodorant, toothpaste, hairspray or any other toiletries.

Travel-sized deodorant is readily available at many stores, and it gives you one less thing to think about when traveling.

As all the big brands make travel-sized deodorant, so you should have no problem finding your favorite brand.

Toiletries You Can’t Bring on a Plane

As long as you follow the TSA’s 3-1-1 rule, you can bring all of your toiletries on a plane in your carry on bags.

To reiterate, if the toiletry is a liquid, gel, or spray in a container that is less than or equal 3.4 oz/100ml, you will have no problem packing it in your carry on.

Some items can be confusing, though, which is what trips most people up.

Lip balm, cream blush, lipstick, and toothpaste, for example, all qualify as either liquids or gels.
