Flying can be stressful enough without the added hassle of having your favorite items confiscated at security. While most travelers know the basics—liquids over 3.4 ounces, sharp objects, and firearms are a no-go—the Transportation Security Administration (TSA) has a surprisingly long list of lesser-known prohibited items. Some of these might shock you, especially if you’ve packed them before without issue. 

To save you from last-minute baggage checks and awkward encounters with TSA agents, we’ve compiled unexpected items banned from hand luggage on flights in America, based on the latest TSA guidelines.

1. Snow Globes (Yes, Really!) 

You might think these charming winter decorations are harmless, but the TSA considers them a liquid. Since they contain water (and sometimes glycerin), they fall under the 3-1-1 liquids rule, meaning any snow globe larger than 3.4 ounces (100ml) must go in checked baggage. Even smaller ones might raise eyebrows if security can’t determine their volume easily. 

2. Gel Shoe Insoles 

Comfortable shoes are a must for long flights, but if you’re using gel-based insoles, you could run into trouble. The TSA classifies these as gels, meaning they must comply with liquid restrictions. If they’re too bulky or contain too much gel, security might pull them out for inspection. 

3. Protein or Peanut Butter (Most Spreadable Foods) 

You’d think snacks are safe, but peanut butter, hummus, yogurt, and even some protein spreads are considered gels or pastes by the TSA. If they’re over 3.4 ounces, they’re not allowed in hand luggage. Stick to solid snacks like granola bars or whole fruit to avoid surprises. 

4. Large Batteries (Including Some Power Banks) 

While most portable chargers are allowed, lithium-ion batteries over 100 watt-hours (common in high-capacity power banks) require airline approval. Spare batteries must also be carried in hand luggage—not checked—due to fire risks. Always check your power bank’s wattage before packing. 

5. Sports Equipment (Bats, Golf Clubs, Hockey Sticks) 

Planning to bring your baseball bat, golf clubs, or hockey sticks? Think again. The TSA prohibits most sports equipment that could be used as weapons in hand luggage. These must be checked, though some airlines have additional restrictions. 

6. Tools (Even Small Ones) 

That screwdriver or wrench in your carry-on? Not allowed if it’s longer than 7 inches. The TSA restricts most tools that could be used as potential weapons. If you’re traveling with tools, pack them in checked baggage. 

7. Self-Defense Items (Pepper Spray, Brass Knuckles) 

While pepper spray is allowed in checked baggage (under 4 oz), it’s completely banned in hand luggage. The same goes for brass knuckles, stun guns, and martial arts weapons. Even if you have a permit, these won’t make it past security. 

8. Dry Ice (Without Airline Approval) 

Need to keep something frozen? Dry ice is allowed—but only up to 5.5 pounds (2.5 kg) and only with airline approval. It must also be properly ventilated to prevent carbon dioxide buildup. 

9. Electronic Cigarettes & Vapes 

While you can bring vapes and e-cigarettes on board, they cannot be used during the flight and must stay in your hand luggage (not checked bags) due to battery fire risks. Some international flights ban them entirely, so check your airline’s policy. 

10. Hoverboards & Smart Luggage with Non-Removable Batteries 

Those self-balancing scooters (hoverboards) and some smart luggage with built-in batteries are banned if the battery can’t be removed. Lithium battery fires have led to strict regulations, so double-check before packing. 

11. Gel-Type Candles 

Like snow globes, gel candles fall under the TSA’s liquid restrictions. If they contain more than 3.4 ounces of gel, they must go in checked baggage. 

12. Flammable Liquids (Including Some Toiletries) 

Nail polish remover, lighter fluid, and even some aerosol deodorants are restricted. While travel-sized toiletries are usually fine, larger quantities may be confiscated. 

13. Certain Medical Supplies (Liquid Oxygen, Large Quantities of Alcohol) 

While most medical items are allowed, liquid oxygen is banned entirely. Large amounts of rubbing alcohol or hydrogen peroxide (over 3.4 oz) may also be flagged. 

14. Fresh Fruits & Vegetables (Some International Restrictions) 

While the TSA allows most food, certain fruits and vegetables are banned due to agricultural laws. If you’re flying internationally, check customs rules. 

15. Camping Gear (Fuel, Strike-Anywhere Matches) 

Camping stoves with fuel, lighters, and strike-anywhere matches are prohibited in hand luggage. Some are allowed in checked bags, but always check airline policies. 

Final Thoughts: Check Before You Fly!
