15 Things You Can Now Bring In Your Carry-On With TSA Approval

Most travelers still pack with caution, assuming the TSA playbook hasn’t changed much. But a handful of small but useful updates have flown under the radar. Several everyday items that were once questionable at checkpoints are now approved for carry-ons in standard, usable sizes. These aren’t sweeping changes, but they can definitely ease the stress of prepping for a flight. Here’s a look at what’s now allowed in your bag.

Baby Essentials (Formula, Food, And Milk)

Some travelers board with nothing but earbuds and a backpack. Others juggle teething rings, bottles, and puree pouches. For parents in the latter camp, TSA now permits baby essentials in full-size quantities; no measuring or rationing is needed. As long as it’s for the baby, it’s a yes.

Liquid Medications (Prescription & OTC)

There’s no need to panic over a bottle of insulin anymore, worrying it might be discarded. Now, if it’s medically necessary, it’s allowed—without volume restrictions, as long as you give a heads-up at the checkpoint. This simple reassurance reduces health concerns during flights and ensures a smoother, stress-free journey.

Contact Lens Solution

Packing light doesn’t mean sacrificing comfort, especially when it comes to contact lenses. Contact lens solution is classified as a medically necessary liquid, so you can bring larger bottles if needed—just make sure to declare it. However, to avoid delays at security, TSA suggests packing bottles over 3.4 ounces in your checked luggage when possible.

Duty-Free Liquids In Secure Bags

Not all souvenirs fit in a suitcase—some shimmer, others splash. If purchased at an international duty-free shop, liquor or perfume can pass security if sealed, tamper-evident, and unopened. This isn’t a loophole but a well-defined rule for cross-border travelers.

Frozen Gel Packs (For Medical Use)

Gel packs can be a lifesaver, whether keeping medications stable or food fresh. While it’s allowed, there’s one strict rule: they must be fully frozen at the time of screening. There is no exception to this rule; being ice cold is your safest bet.

Liquid Vitamins And Nutritional Drinks

Heading out on a red-eye with a full bottle of meal replacement? TSA says yes, as long as it supports your health. For travelers with dietary conditions, this small allowance can mean bypassing airport food courts altogether. As long as it serves a personal health need, it’s cleared for takeoff.

Live Fish In Water

Live fish in carry-ons are permitted if they’re in a clear, spill-proof container. The water must be visible and secure, or it won’t make it through. No special paperwork is required. You’ll need to take it out at screening, but the rule stands.

Biological Specimens (Like DNA Samples)

Lab couriers, medical tourists, and others shipping important items all benefit from this rule. As long as the container is leak-proof and the packaging is triple-sealed, you’re in the clear. It might not be your typical carry-on, but it certainly has a designated spot above the seat.

Wet Batteries (Non-Spillable, Medical Devices)

Mobility is non-negotiable. Travelers relying on electric wheelchairs or power-assisted tools often carry wet cell batteries, and now, those get the green light—if they’re sealed and properly packed. TSA doesn’t require them to be removed, either. 

Fresh Eggs

TSA allows you to bring eggs on a flight, even uncooked ones. With the right packing to keep them safe, you can easily travel with fresh eggs and ensure your meals stay intact and ready for use, no matter where you’re headed.

Liquid-Filled Snow Globes (Small Size)

For years, snow globes sparked confusion at checkpoints. Too big? Confiscated. Too leaky? Tossed. Now, if the entire globe fits in a quart-sized bag and holds under 3.4 ounces of liquid, it’s approved. A fragile little winter scene finally earns its boarding pass.

Hand Sanitizer (Up To 12 Ounces)

Hand sanitizer is allowed in carry-on baggage in containers up to 3.4 ounces, following the 3-1-1 liquids rule. Travelers must present it separately in a quart-sized bag during screening. Larger bottles should be packed in checked luggage to avoid security delays.

Canned Foods (Like Soup Or Tuna)

Solid canned foods, like drained tuna or meats, can be carried in a carry-on without liquid restrictions, though they may require screening. Canned goods with liquids must follow the 3-1-1 rule, meaning containers must be 3.4 ounces or less. Pack them upright to avoid leaks.

Peanut Butter And Other Spreads

Peanut butter often stirs up confusion at airport security. In 2023, TSA categorized it as a liquid, sparking some debate. While you can still bring it, full jars aren’t allowed unless medically necessary. To avoid any hassle, declare it at security, pack it carefully, and save the snacking for later in the journey.

CPAP And Nebulizer Liquids

For those who rely on medical devices, like respiratory equipment, TSA regulations offer some flexibility. Water for these devices is allowed without the need for transferring it into smaller bottles. Just make sure to keep it visible and inform security for a smooth screening process.
