Up, Up and Away

Traveling allows us to explore new cultures, try new foods, and immerse ourselves in exciting adventures that can last a lifetime. But in order to get to these dreamy destinations, one must first deal with the Transportation Security Administration (TSA), which can be a stressful ordeal. But knowing what might get your carry-on or checked luggage flagged can save you from unexpected delays and hassles.


From prohibited items to unusual packing choices, there are several things that could raise a red flag for TSA agents. Here are 17 things to look out for while packing.

1. Liquids Over 3.4 Ounces

While the 3-1-1 rule for carry-on liquids is well-known, many travelers forget that checked luggage can also be scrutinized for liquid content. Any liquid containers exceeding 3.4 ounces — especially if they’re not properly sealed — could attract extra scrutiny. This includes items like shampoo, lotions, and of course, beverages.

2. Prohibited Items

Certain items are outright banned from air travel, including firearms, explosives, and certain types of chemicals. Even if you think you're bringing something that's harmless, it’s always best to check the TSA’s prohibited items list before packing it. Attempting to travel with these items (even accidentally) can result in significant delays — and possibly legal trouble.

3. Unusual Electronics

Large or complex electronic devices like drones, gaming consoles, or even certain types of cameras can look suspicious on an X-ray machine. These items might require additional screening to ensure they’re not hiding anything dangerous. To expedite the process, consider placing electronics in easily accessible areas of your luggage.

4. Unsealed Food

While sealed, store-bought food typically passes through security without issue, homemade or unsealed foods can be problematic. TSA agents might need to inspect these items to ensure they’re not hiding prohibited substances. To avoid delays, pack food items in clear, resealable bags or containers to make the inspection process easier. Be prepared to explain what the food items are if questioned by security.

5. Dense Books

A large stack of books, or very thick volumes, can appear unusual on an X-ray scan. The dense nature of books makes it hard for the scanner to see through them, which can prompt a manual inspection. If you’re traveling with several books, consider spreading them out across your luggage. Or, consider using an e-reader like a Kindle to avoid the extra weight and potential scrutiny from the TSA.

6. Wrapped Gifts

While wrapped presents are cute and festive, TSA agents might need to unwrap them to see what’s inside. This can be frustrating — especially if you’ve taken time and effort to wrap the gifts nicely. To avoid this hassle, consider using gift bags or wrapping paper after you’ve reached your destination. If you must travel with wrapped gifts, be prepared for the possibility that they might be unwrapped during inspection.

7. Large Amounts of Powder

Powdered substances, such as baby and protein powder, or cosmetics, can be problematic if they exceed 12 ounces. These substances can resemble more dangerous materials and might require additional testing. To avoid this, pack powders in their original containers and keep the quantities small to minimize delays. If you need to travel with larger amounts, be prepared for them to be inspected more thoroughly.

8. Fruits and Vegetables

Fruits, vegetables, and plant materials can be flagged or banned outright. This is because fruits and vegetables can pose agricultural risks that can introduce pests or diseases to new environments. Check the regulations for the specific destinations you’re traveling to and from, as they can vary widely. Whenever possible, avoid packing organic materials in your checked luggage in order to sidestep potential issues.


When entering the U.S., the United States Department of Agriculture (USDA), generally does not allow fruits or vegetables of any kind (whole or cut). "This includes fresh fruits or vegetables given to you on your airplane or cruise ship," says the USDA.

9. Sports Equipment

Items like baseball bats, golf clubs, or other sporting goods can attract attention due to their size and shape. These items could be seen as potential weapons and might need to be inspected more thoroughly to ensure they’re safe for travel. Make sure any sports equipment is packed securely and consider using specialized travel cases.

10. Heavy Tools

Tools over 4 inches in length, such as hammers or wrenches, can be seen as potential weapons and are not allowed in carry-on bags. Even if you’re just bringing them for a work trip, they could cause delays at security. To avoid this, pack these items in a way that they’re easily identifiable and explainable to TSA agents. Using clear, well-labeled containers can also help speed up the inspection process.

11. Sharp Objects

Sharp objects like knives, scissors, and other prickly items will almost always be scrutinized by TSA for safety reasons. These items must be securely packed and meet TSA guidelines to be allowed in checked luggage. Double-check that all sharp objects are properly sheathed or wrapped to prevent injuries. Inform TSA agents about any sharp objects to ensure they’re aware and can handle them appropriately.

12. Unusual Textures

Items with unusual textures or densities, such as gels, pastes, or certain fabrics, might receive a second look to rule out the possibility of hidden contraband or hazardous materials. Pack such items in clear containers and be ready to explain their purpose if questioned. Keeping documentation or receipts for unusual items can also be helpful.

13. Medical Devices

Uncommon medical devices or equipment such as insulin pumps and CPAP machines may require additional inspection to verify their purpose. If you’re traveling with medical equipment, make sure you bring along necessary documentation, such as a doctor’s note or prescription, and inform TSA agents. Packing these items in easily accessible areas can also help streamline the security process.

14. Batteries

Lithium batteries, especially loose ones, are a red flag for safety reasons due to the risk of fire or potential explosion. As such, consider bringing batteries in their original packaging or secure them in battery cases to prevent short-circuiting. Also, beware of the specific regulations regarding the types and quantities of batteries allowed.

15. Aerosol Cans

Certain aerosol products, such as spray paint or large cans of hairspray, are restricted and could get your luggage flagged. These items are considered flammable or hazardous materials, and must be packed according to TSA guidelines. Check the specific regulations for aerosol products before packing them. If you must travel with aerosols, pack them securely and inform TSA agents about their presence.

16. Excessive Cords

Stuffing a tangled mess of cords and cables into your bag can look suspicious on scanners, and might prompt a manual inspection. To avoid this, organize your cords and cables neatly using cable ties or pouches. Packing them in clear bags can also help TSA agents see what they are without having to unpack everything.

17. Any Oddly Shaped Objects

Lastly, unusual shapes can trigger a manual inspection because they stand out on X-ray machines. These could be anything from unique souvenirs to custom-made items, even adult toys or toys for pets like the one pictured. Pack such objects in a way that makes their purpose clear and easy to explain.
