Airport security can be strict about what travelers can bring on board, and there are 11 unusual items airport security won't let you carry on. Understanding these restrictions is important to avoid surprises at the checkpoint. From everyday items that might seem harmless to more surprising objects, knowing what to leave behind can make the travel experience smoother.

Many travelers may not realize that certain items, like specific sports equipment or unusual tools, are not allowed in carry-on luggage. These rules are in place for safety reasons, but they can sometimes catch people off guard. Being aware of these restrictions ahead of time can help prevent delays and frustration during the security process.

Check out these unusual items that are not permitted at airport security. Being informed can help ensure a hassle-free travel experience and allow for a more enjoyable trip!

Snow globes are a popular souvenir, but their liquid content makes them tricky for carry-on luggage. Unless the globe is small enough to fit within the TSA’s liquid allowance (3.4 ounces or less) and placed in a clear, quart-sized bag, it won’t pass security. The liquid inside is treated as any other liquid, regardless of how decorative the globe may be. Larger globes must be packed in checked luggage to avoid being confiscated. If you're unsure, measure the globe's volume or check with your airline for specific advice before bringing one through the security checkpoint.

Bowling Pins

Though they might seem like an unusual item to bring to the airport, bowling pins are flagged as potential blunt objects that could be used as a weapon. Their solid, heavy design makes them problematic for carry-on bags. If you’re traveling to a tournament or simply taking your equipment for leisure, pack the pins in your checked luggage to avoid issues at the security checkpoint. As bowling balls are usually allowed in carry-on luggage, you may want to keep the two items separate to comply with regulations.

Magic 8 Balls

Magic 8 Balls are a fun novelty item, but they contain liquid hidden inside their hard plastic shell. The liquid far exceeds the TSA’s limit of 3.4 ounces for carry-on liquids, which means it will be confiscated if packed in your hand luggage. If you must travel with one, it needs to go in checked baggage. Keep in mind that the liquid is not always obvious at a glance, so many travelers are surprised when their toy is taken during screening. It’s always worth double-checking items like this in advance.

Canned Foods

Canned foods might seem travel-friendly due to their durability, but the liquid inside them often causes problems at airport security. Soups, sauces, and other canned goods are classified as liquids, even if the food itself appears solid. Containers larger than 3.4 ounces will be flagged and likely confiscated unless packed in checked luggage. Additionally, metal cans can trigger alarms during X-ray screening, slowing down your security process. If you're traveling with specialty canned goods or homemade items, it’s better to check them to avoid delays or confiscation.

Cast-Iron Cookware

Cast-iron pans are a no-go for carry-on bags due to their weight and solid construction, which security considers potentially dangerous. These heavy-duty items are flagged as possible blunt instruments that could cause harm if misused. Travelers often attempt to bring them as carry-ons due to their high value and fragility, but this typically results in confiscation. To avoid issues, pack cast-iron cookware carefully in checked luggage, using padding to protect both the pan and other items. While inconvenient, this is the only way to travel with these durable kitchen tools.

Golf Clubs

Golf clubs are not permitted in carry-on luggage due to their size and potential to be used as blunt objects. Whether you’re traveling for a tournament or a casual trip, these items must be packed in checked baggage. Most airlines recommend using a hard-sided travel case for added protection. Attempting to carry even a single club onboard will likely lead to delays at security, as they don’t meet TSA guidelines. Always check your airline’s specific baggage rules for transporting sports equipment, as weight limits and fees can vary depending on the destination.

Camping Stoves

Camping stoves, even when empty of fuel, are subject to strict scrutiny by airport security. The residual odor or trace amounts of fuel can trigger alarms or cause the item to be denied at security checkpoints. For safe transport, thoroughly clean the stove to remove any remaining fumes or residue. Some stoves may still be flagged due to their design, so packing them in checked luggage is the safest option. If you’re bringing fuel canisters, be aware that they are prohibited in both carry-on and checked baggage, so plan accordingly.

Cremated Remains

Traveling with cremated remains can be a sensitive and stressful process. The TSA permits remains in carry-on luggage, but only if the container is made of a material that allows X-ray screening, such as lightweight plastic or cardboard. Metal or opaque urns that block the scanner’s view will likely be flagged, and security agents are not allowed to open the container. To avoid complications, choose a TSA-compliant urn and carry the appropriate documentation, such as a death or cremation certificate, to streamline the process at checkpoints.

Foam Toy Swords or Guns

Toy weapons, even those made of foam or plastic, are frequently flagged by airport security due to their resemblance to actual weapons. While these items are clearly toys, TSA regulations err on the side of caution, leading to confiscation. If you’re traveling with children who want to bring their toys, pack foam swords or guns in checked luggage to avoid issues at the checkpoint. This policy is part of broader efforts to prevent misunderstandings or unnecessary delays, as realistic-looking items can still cause confusion during security screenings.

Jars of Peanut Butter

Peanut butter, though spreadable, is considered a liquid under TSA guidelines. Any container exceeding 3.4 ounces will be confiscated if found in carry-on luggage. Even partially filled jars are not allowed if the container’s total capacity exceeds the limit. Travelers often overlook this restriction, as peanut butter doesn’t behave like traditional liquids. To avoid confiscation, pack larger jars in checked baggage. Alternatively, consider purchasing travel-sized portions that comply with the liquid rule. This will save time at security and ensure your snack or meal prep remains intact.

Surge Protectors with Extension Cords

Surge protectors that include extension cords or multi-outlet hubs are often flagged at security checkpoints. They can resemble prohibited items in X-ray scans due to their wiring and bulk. Additionally, some are restricted due to concerns about fire hazards in the cabin. If you need one for your trip, consider packing it in your checked luggage to avoid delays. Make sure it is in good condition, with no exposed wires or damage, as faulty items may raise additional concerns. Always check TSA guidelines for electronics to avoid surprises.
