Collection: 10 Items You Can't Bring Through TSA Security: A Comprehensive Guide

Traveling can be a thrilling experience, but navigating through airport security can sometimes be a confusing process. The Transportation Security Administration (TSA) has clear guidelines on what can and can't be taken on a plane. However, the rules often change, and many travelers are left unsure about what they can pack in their carry-on bags. This article aims to provide a comprehensive guide on ten items you can't bring through TSA security, helping to make your next trip smoother and more enjoyable.

Before we dive into the list, it's worth noting that there are programs available that can expedite your journey through airport security. Global Entry and TSA PreCheck are two such trusted traveler programs. Both of these programs can save you significant time at the security checkpoint, and applying for TSA PreCheck or enrolling in Global Entry is a straightforward process. Once you're approved, you'll be given a Known Traveler Number (KTN) that you can add to your boarding pass to enjoy expedited security checks.

1. Liquids Over 3.4 Ounces

The 3-1-1 rule is the cornerstone of the TSA's liquid limit rule. It states that any liquids, aerosols, gels, creams, and pastes in your carry-on bag must be in 3.4 ounces (100ml) containers or smaller. These containers should be packed in a single, clear, quart-sized, zip-top plastic bag. Only one such bag is permitted per passenger.

There are exceptions to this rule, such as for medications and certain other necessities. For example, breast milk, formula, and juice for infants or toddlers are exempt from the 3-1-1 rule. If you're traveling with an infant or a toddler, you can bring a reasonable amount of these liquids, which do not need to fit in a quart-sized bag. However, you must declare these liquids for inspection at the security checkpoint, and they may be subject to additional screenings.

2. Large Containers of Hand Sanitizer

In response to the COVID-19 pandemic, the TSA temporarily allowed passengers to carry one liquid hand sanitizer container, up to 12 ounces per passenger, in carry-on bags. However, this exemption expired, and as of now, hand sanitizers must follow the 3-1-1 rule for liquids.

3. Sharp Objects

Sharp objects, such as box cutters, knives, and scissors with blades longer than 4 inches, are prohibited in carry-on bags. These items must be packed in your checked luggage.

4. Sports Equipment

Certain sports equipment that can be used as a bludgeon, such as baseball bats, golf clubs, hockey sticks, and pool cues, are not allowed in carry-on bags. They must be transported in your checked luggage.

5. Guns and Firearms

Guns and firearms are not permitted in carry-on bags under any circumstances. They must be unloaded, packed in a locked hard-sided container, and declared to the airline at check-in.

6. Flammable Items

Most flammable items, including flares, gasoline, lighter fluid, and torch lighters, are not permitted in carry-on or checked bags. However, one lighter or one pack of safety matches are allowed on your person.

7. Certain Tools

Tools longer than seven inches, including wrenches and pliers, are not allowed in carry-on bags. They must be packed in your checked luggage.

8. Self-Defense Items

Self-defense items like pepper spray, mace, and stun guns are not allowed in carry-on bags. They can be packed in checked bags under certain conditions.

9. Certain batteries

Certain batteries, particularly those that are damaged or have a high likelihood of causing a fire, are prohibited in carry-on and checked bags. This includes car batteries, wet batteries, and certain types of lithium batteries. However, most consumer batteries, such as AA, AAA, C, D, 9-volt, button-sized cells, and laptop batteries, are allowed in carry-on bags.

10. Explosive Materials

Under no circumstances are explosive materials allowed on an aircraft. This includes firecrackers, fireworks, dynamite, and other substances that could potentially cause harm or danger to passengers and crew.

In Summary

Knowing what you can't bring on a plane is just as crucial as knowing what you can. For international travelers, it's also worth noting that the rules can vary depending on the country you're flying into or out of. Always check the local regulations before you fly.

While these rules may seem limiting, they are designed to keep everyone safe during their travels. To avoid any potential delays at airport security, it's recommended to pack wisely and always double-check your carry-on bag for any items that may not be TSA-approved.

If you're a parent or guardian traveling with a child, it's also important to remember that the same rules apply to everyone, regardless of age. As such, make sure to educate your children about these rules to ensure a smooth journey.

Lastly, remember to keep all your carry-on liquids in a clear, quart-sized plastic bag and have your boarding pass and identification ready at the security checkpoint. With these tips and your knowledge of what items to avoid packing, you're now ready for a hassle-free journey through airport security.

In conclusion, while airport security may seem daunting, being prepared and knowing what items are prohibited can make your experience a lot smoother. Consider enrolling in a Trusted Traveler Program like Global Entry or TSA PreCheck, pack smart, and you'll be well on your way to a pleasant and stress-free travel experience.
