Air travel has many strict rules that passengers need to follow in order to check in and fly on planes. A lot of these rules revolve around the items you can carry onto a plane either in your check-in baggage or carry-on baggage.
Most of the items you can’t carry on planes are dangerous items that could be used to harm or threaten other passengers or staff, such as scissors, small blades, or lighters.
There are, however, also other items that you can’t carry on a plane such as perfume or any toiletries that are over 100ml (3.4 ounces).
Deodorant is one of the items that are a bit more complicated, deodorants come in different sizes, but they also come in different forms. You can have a spray-on deodorant that comes in aerosol bottles as well as a roll-on deodorant, which is a liquid and a solid deodorant that comes in sticks.
This article will explore the question of bringing deodorant onto a plane and what precautions you need to take when packing deodorant.
Can I Take Deodorant on a Plane (in my checked Baggage)?
The short answer is yes, your checked-in baggage can carry any type of deodorant inside it. When it comes to liquid and solid deodorant, there are no rules you have to follow when packing.

You can put in any size and any quantity of these types of deodorant so you don’t have to worry about your hygiene when you get to where you need to go.
When it comes to aerosol deodorants when packing your bags, you are allowed to pack them in your suitcase, however, there is a limit to the quantity of aerosol deodorant you can pack.
Toiletry aerosols in checked baggage must not exceed 70 ounces total, and each container must be under 18 ounces. This is to prevent a dangerous amount of flammable aerosol from being stored on the plane.
You must remember that when you are boarding a plane, the final decision on whether or not your items will be allowed on the plane is decided by the TSA officers that check your suitcase.
Even if you have followed the parameters, the final decision is with them.
Can I Take Deodorant on a Plane (in my Carry-on bag)?
Again, the short answer for this is yes.
However, there are way more terms when it comes to carry-on baggage than there is check-in baggage. This is because while an item is in your check-in baggage, it is safely stowed away and you cannot access it, but while the item is in your carry-on baggage you are able to use it when you are flying.
Solid or Stick Deodorants
Solid or stick deodorants are fine to take on carry-on luggage in any quantity as they pose no immediate threat to the people on the plane.
If you are planning on using deodorant on the plane then we recommend taking a small travel-sized stick of deodorant in your carry-on baggage.
Liquid and aerosol deodorant
Liquid and aerosol deodorant you can bring onto a plane but only in certain quantities, both of these forms of deodorant have a capacity on the amount you can bring on.
The liquid or aerosol deodorant must be less than 100ml or 3.4 ounces as large quantities of liquid and aerosol deodorant can be flammable and therefore be a danger to passengers and staff on the plane.
As with the check-in luggage, the TSA agent that checks your carry-on baggage at the airport security ultimately has the last say on what you can or cannot bring on the plane.
Even if the amount of deodorant you have is under the necessary limit, the TSA agent can still rightfully remove it from your baggage.
What About Powdered Deodorant?
Since powdered deodorant is not considered a liquid by the TSA then there is no rule in place about bringing them onto planes, so you are allowed to carry powdered deodorants in carry-on baggage and checked baggage.
However, it may require screening while going through security in the airport and the TSA recommends that you don’t pack a powdered deodorant that is over 12 ounces.
Final Thoughts: Deodorant on a Plane
You can bring deodorant onto a plane of any kind, however, there is a TSA guideline that prevents you from bringing liquid and aerosol deodorant into your carry-on baggage if it is over 100ml (3.4 ounces).
Aerosol deodorant also has a limit on the quantity you can carry in check-in baggage not exceeding a total of 70 ounces and each container being below 18 ounces.
Always keep in mind that the final decision on whether your deodorant is allowed on the flight is determined by the TSA officer at the checkpoint.
