What items are prohibited on planes?

Although a variety of airlines have different rules and regulations, there are still many things not allowed by every airline. TSA mainly prohibits harmful materials for safety reasons. You must follow TSA rules and cooperate with them. Airlines have different rules for domestic and international flights. Some items are prohibited in carry-on luggage but allowed in checked luggage, so doing extensive research about these items is very helpful.

Lithium batteries, Fireworks, ammunition, drugs, flammable liquid, compressed gas, acids, pocket knives, and throwing stars are not allowed to carry on the plane.

These Items are not allowed on a plane carry-on

If you are going on a short trip, there is no need to carry checked luggage. Packing your items in handbags has several benefits. You can reduce the risk of your bag being stolen or misplaced by keeping it with you during the flight. You can access your items anytime, but you can only pack your essential items. There is not much space in the carry-on bag to hold all the items you want because handbags have less space than checked luggage. Following are the items that you can’t keep in your handbag.

  • Kitchen tools
  • Aerosol insecticide
  • Ammunition
  • Baseball bats
  • Peanut butter
  • Gel-type candles
  • Pepper spray

Kitchen tools

Some kitchen tools with sharp edges are not allowed to be carried in carry-on luggage during flights.

Items with sharp ends are not weapons, but they can penetrate and injure a person. That’s why TSA considers them to be prohibited items. Strong-bladed items are prohibited in carry-on luggage and can only be transported in checked luggage. Keeping knives or cutters with sharp ends is prohibited, but if you want to keep them, pack them properly. After packing, keep them in a separate bag and then put them in the bag.

Aerosol insecticide

Because aerosol insecticides can be accessed at any time during the flight, TSA prohibits them from being carried in hand luggage. Aerosol insecticides contain dangerous material, so you are not permitted to carry them into your carry-on. However, if you want to keep them with you, they can be packed properly in checked luggage. You have to place a tag of hazardous material on them along with your name. This is so that if TSA separates them from checked luggage, they can inquire about you.


For ammunition, you have to read your airline’s instructions. Make sure you check with them about whether you can take ammunition or not. According to TSA, ammunition is strongly prohibited in carry-on luggage. Arm ammunition can be kept in checked luggage but only a small quantity can be packed in fiber or wooden boxes. If you want to take them, you need to be careful during packing and obey the laws.

Baseball bats

We can pack sports items in carry-on luggage. Cricket and tennis balls are allowed to keep. However, you can’t keep bats in upheld bins. Someone can only pack these in checked luggage. Hockey sticks, ski poles, and hiking poles are also banned from carry-on luggage.

Peanut butter

You might think that TSA only prohibits dangerous items, so why I am putting peanut butter on the prohibited list? In fact, TSA prohibits taking liquid items on the plane and it categorized peanut butter as liquid. That’s why you can’t take in your carry-on luggage. However, you can keep its limited amount in a container rather than a full jar.

Gel-type candles

According to the TSA, these candles are not permitted to be kept in carry-on luggage while flying. You can keep these candles in your checked luggage only. Although solid wax candles are allowed to be kept in checked luggage.

Pepper spray

TSA prohibits pepper spray from being carried in carry-on luggage. You are not allowed to keep self-defense gas. Checked luggage has specific limits. You can pack one 118ml container in your checked luggage. For self-defense sprays, you can’t keep a spray that contains more than 2 percent tear gas in it. Check out your airline’s guidelines regarding the quantity of spray in checked luggage.

At screening, take these items from your carry-on and submit them for additional screening. Make sure to pack them in a translucent bottle so that they can be easily identified and checked without cluttering the image.

Many people think that milk may not be safe for your toddler after being passed through X-rays, but there is no need to worry about that. Nothing to worry about. Milk is completely safe and is widely used by children. In spite of this, if you don’t want these things to pass through the X-ray screening, you can request them directly.
