Whether you are using your carry-on bag as your main bag for your trip or packing extra items in the event your luggage ends up on the wrong plane, there are some items you need to be aware of that you cannot have in your carry-on luggage. If you plan on bringing any of the following items, you will need to find an alternative or if you absolutely need it, store it in checked luggage.

Liquids

Anything less than 3/4 oz/100 ml is allowed. However, anything above that is not permitted in your carry-on bag. This includes liquids, aerosols, and gels. All containers must also be able to fit in a clear, one-quart sized, zip-top plastic bag. Make your life easier and buy travel sized bottles for shampoo, conditioner, shower gel, and other products you want to bring along with you. Some items that people don’t consider liquids but actually are, include mascara, concealer, dry shampoo, peanut butter, and glow sticks.

Sharp Objects

This should be a given since sharp objects carried onto a plan can be considered a weapon. Scissors that are less than 4 inches in length, such as nail scissors, and typically allowed by TSA, however, it all depends on the agent. Items, like disposable razors, are okay since the blade itself is attached to a handle. If you are traveling internationally, some of the rules in other countries differ from those in the US, so make sure you read up on those before you fly.

Flammables

Flammable items, like bulk matches, bulk lighters, lighter fluid, and camping stoves, are prohibited in carry-on and checked luggage. You can check with TSA and the airlines before you arrive, but if possible, try to hold off and purchase the items when you arrive at your destination. TSA does allow one lighter or one pack of safety matches in your carry-on bag (this does not include electronic lighters or e-lighters), but they are not allowed in your checked bag. Additionally, e-cigarettes and vapes are acceptable in your carry-on. However, the liquid for these devices must meet the liquid allowances.

These items are some of the more common items that are confiscated when going through security, but these are by no means all of them. Check with TSA and your airline before your flight if you are unsure about any of the items you are taking with you to avoid any hassle and make going through security as much of a breeze as it can be.
