What you can and cannot carry-on a plane

When preparing for a flight, it's important to know what items are allowed in your carry-on bag, as well as what items are prohibited. The Transportation Security Administration (TSA) has strict guidelines for what can and cannot be brought on board a flight, and failure to comply with these guidelines can result in your items being confiscated or, in some cases, even result in arrest.

Weapons

The most common prohibited items in a carry-on bag include weapons, such as knives, firearms, and ammunition. This includes anything that could be used as a weapon, such as a baseball bat, hockey stick, or golf club. Replica weapons and toy weapons are also prohibited.

Explosive and flammable items

Explosive and flammable items are also prohibited in carry-on bags. This includes fireworks, flares, and gasoline. Aerosol cans, such as hairspray, mace, and pepper spray are also prohibited, as are lighters and matches.

Sharp objects

Sharp objects, such as scissors, box cutters, and knives, are not allowed in carry-on bags. This also includes tools, such as hammers and drill bits. Sports equipment, such as baseball bats, hockey sticks, and golf clubs, can also be considered prohibited items, depending on the airline's policy.

Liquids, gels, and aerosols

Liquids, gels, and aerosols are also restricted in carry-on bags. Each passenger is limited to one quart-sized bag of liquids, and each container must be 3.4 ounces or less. These items must also be placed in a clear, plastic bag for easy inspection.

Illegal drugs or substances

It's also prohibited to bring any illegal drugs or substances on board, as well as items that are considered to be too dangerous, such as acid, bleach, and fertilizer.

Certain items are allowed in carry-on bags, but may be subject to additional screenings and inspections. Examples include electronic devices, such as laptops, tablets, and cell phones, as well as foods, such as sandwiches and fruits.

Security and customs regulations

It's also important to check with your specific airline for their carry-on baggage restrictions and guidelines, as they may have additional or different restrictions than the TSA. Additionally, if you are traveling internationally, be sure to check with the specific country's security and customs regulations, as they may have different restrictions than the TSA.
