Solid stick deodorant has no limitations and can be any size
If you're travelling with deodorant, it's important to know the rules and regulations to avoid having to throw away your favourite product at security. The good news is that solid stick deodorant is allowed in carry-on bags with no size limitations. This means you can pack whatever size you want and don't have to worry about restrictions. It's the same for powder deodorant, which is also allowed in carry-on luggage without any size restrictions.
However, it's worth noting that while solid stick deodorant is allowed, it doesn't mean it won't get flagged by security agents. Some travellers have reported being stopped for carrying stick deodorant, even though it is allowed. In these situations, arguing with security officers is counterproductive, especially if you want to make your flight. So, while you can bring solid stick deodorant, be prepared that you may have to answer questions about it.
If you're travelling with liquid or semi-liquid deodorant, the rules are different. These types of deodorants are subject to restrictions. The Transportation Security Administration (TSA) prohibits containers with more than 3.4 ounces (100ml) of liquid in carry-on luggage. This includes liquid or semi-liquid deodorants, as well as gel deodorants. To comply with the rules, make sure your liquid deodorant is in a container smaller than 3.4 ounces and store it in a quart-sized, zip-top bag.
If you want to bring your favourite deodorant but it's too big for carry-on, you have a few options. You can pack it in your checked luggage, where the restrictions are usually more flexible. Alternatively, many companies sell travel-sized versions of their deodorants, so you can purchase a smaller, travel-friendly option to bring on the plane. You can also buy deodorant after passing through security or once you reach your destination.

Liquids and gels must be under 3.4 ounces
Liquids and gels must adhere to the 3-1-1 rule, meaning that each container must not exceed 3.4 ounces (100ml). This rule applies to deodorants in liquid, semi-liquid, or gel form. These include deodorant paste, roll-ons, and aerosol spray cans. If you are bringing a liquid or gel deodorant, it must be stored in a quart-sized, zip-top bag.
Solid stick deodorants are not subject to the 3-1-1 rule, and there are no restrictions on bringing them in carry-on or checked luggage. They are allowed in any size.
If you are bringing a medically prescribed deodorant or spray, you are allowed to bring larger amounts than the regulated 3.4 ounces. Simply present your doctor's note or prescription to security. It is recommended to be upfront about medical sprays before they are discovered in the x-ray.
To avoid confusion or potential issues, it is always best to review the specific instructions for your type of deodorant or antiperspirant before travelling. Most companies sell travel-size options for their customers' convenience. Alternatively, you can purchase deodorant after passing through the security checkpoint.

Medically prescribed deodorants can be over 3.4 ounces with a doctor's note
Deodorants are allowed in carry-on luggage when travelling by plane, but there are restrictions. The TSA prohibits containers with more than 3.4 ounces of liquid in carry-on luggage. This includes liquid or semi-liquid deodorants, such as roll-ons, gels, creams, or pastes.
However, if you use a medically prescribed deodorant, you can carry larger amounts than the standard 3.4 ounces. To do this, you must keep a copy of your prescription or a valid doctor's note with you when you head to the airport. If your bag is checked, show the note to the TSA agent. It is also recommended to be upfront about your medically prescribed deodorant before the bag checking process begins.
Stick deodorants, on the other hand, are solids that are not considered liquids and are unrestricted in hand luggage. You can carry a solid deodorant of any size onto your flight and do not have to follow the 3.4-ounce rule.
If you do not have a doctor's note and your deodorant is over 3.4 ounces, you may have to purchase a smaller, travel-friendly version, or pack it in your checked luggage.

Roll-ons are often larger and must be packed in checked luggage
Deodorants are allowed in carry-on luggage, but there are some restrictions. The TSA prohibits containers with more than 3.4 ounces of liquid in carry-on luggage. Roll-ons tend to be larger than 3.4 ounces, so they must be packed in checked luggage. If you want to bring your favourite brand of roll-on deodorant, you can buy a travel-size version to take on the plane. These are available at most drug stores and grocery stores.
If your roll-on deodorant is larger than 3.4 ounces, you will need to pack it in your checked luggage. This is because the TSA has implemented restrictions on carry-on items to ensure that nothing dangerous passes through security checkpoints and onto aeroplanes. By restricting liquids and semi-liquids to containers of 3.4 ounces or less, the TSA helps prevent potential liquid explosives from making their way onto flights.
It's important to know the specific guidelines for your type of deodorant to avoid having to throw it away at the airport. If you're unsure, you can always contact your airline in advance to ask about their deodorant-carrying policy.
Solid stick deodorants are not subject to the same restrictions as liquid and semi-liquid deodorants. They are allowed in carry-on bags with no size limitation. This is because solid deodorants do not pose the same security risks as liquids and semi-liquids.
If you have a medically prescribed deodorant that is larger than 3.4 ounces, you are allowed to bring it on the plane. However, it's recommended that you be upfront about your medical sprays before they are discovered in the X-ray. You can simply present your doctor's note or prescription to security.

If you have a medically prescribed spray deodorant, you can bring larger amounts, but you should be upfront about it to security and present your doctor's note or prescription.
Some airlines may have additional restrictions on aerosol sprays, so it is always good to be prepared and check with your airline in advance about their deodorant-carrying policy.
Solid stick deodorants are allowed in carry-on bags with no size limitations. They are not restricted by liquid limitations and are your safest choice. Gel deodorants, on the other hand, need to comply with the 3.4-ounce restriction and be placed in a quart-size bag.
To avoid any problems, it is recommended to buy deodorant after passing through the security checkpoint, as travel-size hygiene products are readily available at convenience stores and grocery stores.
