Below is the latest version (2018) of the TSA Prohibited Items list from the TSA website. Please review this prior to your flight to have a smooth trip through airport security.

The prohibited items list is not intended to be all-inclusive and is updated as necessary. To ensure travelers security, Transportation Security Officers (TSOs) may determine that an item not on the Prohibited Items List is prohibited.

NOTE: Check with your airline or travel agent to see if firearms are permitted in checked baggage on the airline you are flying. Ask about limitations or fees, if any, that apply.

*Permitted in checked baggage only if it does not contain lighter fluid.

NOTE: There are other hazardous materials that are regulated by the FAA. This information is summarized at www.faa.gov, click on Passengers, then Preparing to Fly.

Other Items

Item Carry-On Checked

Hand Warmers

Bringing hand-warmers onto your flight is typically allowed, but some packing rules do apply. These depend on the type of handwarmer, which dictate which set of rules they fall under.

Air Activated - These are the more common disposable types that are activated when you open the package and expose them to air. They contain liquid, so you need to adhere to the TSA 3-1-1 guidelines. They can be packed in both carry-on and checked baggage.

Battery Powered - Battery powered hand warmers are permitted in both carry-on and checked baggage.

Crystallization - This is the type that you flex or squeeze to activate. They contain liquid and require adherence to the TSA 3-1-1 liquids guidelines. They can be packed in both carry-on and checked baggage.

Lighter Fuel - These hand warmers are permitted in carry-on bags. They can be packed in checked baggage as long as they are empty with no noticeable fuel vapors. If they contain fuel, they must be placed in a DOT marked airtight case. Lighter fuel by itself is prohibited all together.

3-1-1 Carry-On Liquids Rules 2018

You are allowed to bring one small bag of liquids, aerosols, gels, creams and pastes through the checkpoint. These are limited to 3.4 ounces or less per container. Consolidating these containers in the small bag separate from your carry-on baggage enables TSA officers to screen them quickly.

3-1-1 for carry-ons = 3.4 ounce (100ml) bottle or less (by volume) ; 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger placed in screening bin. One-quart bag per person limits the total liquid volume each traveler can bring. 3.4 ounce (100ml) container size is a security measure.

Be prepared. Each time TSA searches a carry-on it slows down the line. Practicing 3-1-1 will ensure a faster and easier checkpoint experience.

Declare larger liquids. Medications, baby formula/food and breast milk are allowed in reasonable quantities exceeding three ounces, and they don’t have to be in the zip-top bag. Declare these items for inspection at the checkpoint. TSA officers may need to open them for additional screening.

If in doubt, put your liquids in checked luggage.

You may now carry liquids more than 100 mL in your carry-on bag if:
- You are traveling internationally into the United States with a connecting flight
- they are in transparent containers;
- you bought them at a duty-free shop, and
- the store packed them in a secure, tamper-evident bag.

If your liquids are not in a secure, tamper-evident bag, you must pack them in your checked bag.
