List of Prohibited Items that are not Allowed on a Plane

Flying has become a common mode of transportation for millions of people worldwide. While air travel offers convenience and speed, it also comes with strict regulations to ensure safety onboard. One crucial aspect of these regulations involves the list of prohibited items that are not allowed on a plane. Understanding these restrictions is vital for every passenger to have a smooth and hassle-free journey.

In this comprehensive guide, we highlight  the details of items that are strictly prohibited from being carried onto an aircraft.

Understanding Prohibited Items

Prohibited items are those that are considered too dangerous or pose a risk to the safety of passengers and crew when brought onto an aircraft. These restrictions are put in place by aviation authorities and airline companies to comply with international aviation security standards.

Categories of Prohibited Items

Prohibited items can be categorized into various groups based on their nature and potential threat. The following are some common categories:

Sharp Objects:

Items capable of causing injury or harm due to their sharp edges or points fall into this category. Examples include knives (of any length), box cutters, razor blades, scissors with blades longer than 4 inches (10 cm), ice picks, and swords.

Explosive and Flammable Materials:

Items that are combustible, explosive, or highly flammable are strictly forbidden on airplanes due to the obvious risk they pose. This includes fireworks, flares, gunpowder, dynamite, and other explosives. Additionally, fuels such as gasoline, lighter fluid, and propane are not allowed in carry-on or checked baggage.

Guns and Firearms:

Firearms and ammunition are heavily regulated on planes. Passengers are not allowed to carry firearms, including handguns, rifles, shotguns, or realistic replicas of firearms in their carry-on luggage. There are specific procedures and regulations for transporting firearms in checked baggage, which vary by country and airline.

Sporting Goods:

Certain sporting goods are considered hazardous and are prohibited from being carried onto planes. This includes items such as baseball bats, golf clubs, hockey sticks, ski poles, and martial arts equipment like nunchucks.


Tools that are capable of being used as weapons or pose a threat due to their sharp edges or points are generally not permitted. This includes drills, saws, crowbars, and screwdrivers longer than 7 inches (17.8 cm).

Chemicals and Toxic Substances:

Items such as bleach, tear gas, pepper spray, and other harmful chemicals are strictly forbidden from being brought onto planes.

Liquids, Gels, and Aerosols:

The Transportation Security Administration (TSA) enforces restrictions on the quantity of liquids, gels, and aerosols that passengers can carry in their carry-on baggage. These items must be in containers of 3.4 ounces (100 milliliters) or less and all must fit in a single quart-sized clear plastic bag.


Certain types of batteries, especially lithium batteries, have specific guidelines for air travel due to their potential fire hazard. Spare lithium batteries (not installed in a device) are typically restricted to carry-on baggage and should be protected from short circuiting.

Medical and Personal Care Items:

While most medical and personal care items are allowed, there are restrictions on items like large bottles of medication, liquid oxygen, and certain medical devices that may require additional screening or documentation.

Tips for Packing and Traveling Safely

To ensure a hassle-free experience at airport security checkpoints and compliance with regulations, here are some essential tips for travelers:

Check the Airline’s Guidelines:

Airlines may have specific rules and regulations regarding prohibited items. It’s crucial to check with the airline directly or consult their website before packing.

Read the TSA Regulations: The Transportation Security Administration (TSA) in the United States provides detailed guidelines on what items are allowed in carry-on and checked baggage. Familiarize yourself with these rules to avoid any surprises at the airport.

Use Secure Packaging: For items like electronics and batteries, use appropriate packaging to prevent accidental activation or short circuiting.

Arrive Early: Allow ample time before your flight to go through security checks without feeling rushed or stressed.

Declare Restricted Items: If you’re unsure about an item, it’s always best to declare it to the security personnel for guidance.


Traveling by air is a convenient and efficient way to reach your destination, but it comes with important safety regulations. Knowing what items are prohibited from being carried onto a plane is essential for every traveler. By adhering to these guidelines, passengers contribute to a safer and more secure air travel experience for everyone. Always check with your airline and the relevant aviation authorities for the most up-to-date information on prohibited items before you pack for your next journey.
