Airport security can feel like a guessing game. Most travelers know the basics – no full-size liquids, no sharp objects, no fireworks. But aside from that, things can get a little murky. There’s actually a long list of TSA-approved items that are completely allowed through security, even if they seem questionable at first glance. For example, I once watched a TSA agent calmly wave through someone carrying a frozen acai bowl while I got pulled aside for a rogue tube of toothpaste. That’s when I realized I clearly didn’t know all the rules.
So, let’s take a look at TSA-approved items you didn’t know you could bring through airport security. These are the ones that make people do a double-take when they see them on the conveyor belt, but they’re totally allowed (with a few caveats, of course).
1. Peanut butter (it’s allowed, but it’s complicated)
Peanut butter has caused many a debate in TSA lines. Is it a solid? A liquid? Turns out, TSA classifies it as a “spread,” which falls under the liquids and gels rule. That means you can bring it, as long as it’s in a container that’s 3.4 ounces or less and fits into your quart-sized bag.
So yes, bring your peanut butter, just make sure it’s in travel size. And maybe leave the jar at home.
2. Knitting needles and crochet hooks
If you thought your flight crafting project would be confiscated, good news: TSA allows knitting needles and crochet hooks in both your carry-on and checked luggage. Metal, wood, plastic, it doesn’t matter. As long as they’re not being used as a weapon, they’re allowed.
3. Ice packs and gel packs
You’d think frozen items might be a problem at security, but TSA actually permits ice packs, gel packs, and even frozen liquids if they’re solid at the time of screening. That means if it’s completely frozen when you go through security, you’re good.
4. Breast milk, formula, and juice for babies
Parents traveling with infants or toddlers get a bit of a pass when it comes to liquids. Breast milk, formula, and baby juice are all permitted in “reasonable quantities,” even if they exceed the 3.4 oz rule. You just have to declare them at security, and they might require additional screening.
This rule is incredibly helpful for parents flying with little ones. It’s one less thing to stress about while juggling strollers, diapers, and tiny shoes.
5. Frozen solid meats, pies, and just about anything else
Planning on bringing grandma’s famous pecan pie for the holidays? Go for it. TSA allows pies, cakes, and yes, even whole turkeys, as long as they don’t contain a lot of liquid. You can carry on or check baked goods and frozen meats (as long as, again, they’re solid when screened).
6. Personal safety items (some of them, anyway)
Self-defense tools like pepper spray and stun guns are typically not allowed in carry-ons. However, TSA does permit certain small safety items. For example:
- Personal alarms (those keychain devices that make noise) are TSA-approved.
- Pepper spray is allowed in checked luggage with limitations (must be less than 4 oz and contain less than 2% tear gas).
Always double-check these before you fly, though. They walk a fine line.
7. Corkscrews (with conditions)
TSA actually allows corkscrews in your carry-on, as long as they don’t have a blade (which many do). So if you’re traveling with a wine key or sommelier-style corkscrew that includes a small knife, it will likely get flagged. But a blade-free version? Totally fine. Might come in handy if you’re headed to wine country!
8. Hair clippers and electric razors
Thinking of maintaining that fresh fade while traveling? You can absolutely bring your hair clippers or electric razor in your carry-on. TSA considers them personal grooming tools, and they’re not on the prohibited items list. If you have a grooming kit with scissors, make sure the blades are less than 4 inches long (from the pivot point), or they could be taken.
9. Live fish (yes, really)
Believe it or not, you can bring live fish on a plane in your carry-on bag, as long as they’re in a clear, spill-proof container and the fish is completely submerged in water. TSA allows this, though you should check with your airline first to make sure they’re cool with it too.
Final tips before you fly
Remember, TSA rules can change, and some of the more unusual items can come down to an agent’s discretion. Here are a few smart tips to follow:
- Check the TSA website or use their “What Can I Bring?” tool before flying. You can search just about anything and the website will let you know if you can bring it!
- Always be transparent to the agents at the checkpoint if you have something unusual.
- Label your items clearly, especially if they might not be instantly recognizable.
