Packing for a flight may seem simple, but some everyday items can cause delays at airport security if you place them in the wrong bag. The Transportation Security Administration (TSA) has different rules for carry-on and checked baggage, and some items that look harmless may still require extra screening. Here are some important TSA rules travelers should know in 2026.

What Is the TSA 3-1-1 Liquids Rule?

The TSA 3-1-1 rule applies to most liquids, gels, aerosols, creams, and pastes packed in carry-on baggage. In general:

• Each container: 3.4 oz / 100 ml or less
• One quart-size bag
• One bag per passenger

The rule applies to many common travel products, including toiletries, cosmetics, gels, and certain food items. Some medical and baby-related liquids qualify for exemptions.

TSA Restricted Items Travelers Should Know

Not every restricted item is completely banned from flying. Some items can travel only in carry-on baggage, while others belong in checked luggage. Here are some examples.

Items That Must Stay in Your Carry-On:

Cordless Curling Irons

Keep cordless curling irons powered by lithium batteries, butane, or gas in your carry-on rather than checked baggage. Make sure any required safety cover or protective mechanism is in place.

Electronic Cigarettes and Vaping Devices

Keep electronic cigarettes and vaping devices in your carry-on. Do not place them in checked baggage because their lithium batteries can pose a fire risk. Your airline may also have additional restrictions.

Power Banks and Spare Lithium Batteries

Keep power banks and spare lithium batteries in your carry-on. Do not pack them in checked baggage, as damaged or overheated lithium batteries can create a fire risk.

Items Restricted in Carry-On Baggage:

Gel-Filled Toys

Small gel-filled toys may be allowed in a carry-on if they meet the 3.4-ounce liquid limit. Pack larger gel-filled toys in checked baggage where permitted.

Bowling Balls

Pack bowling balls in checked baggage rather than your carry-on.

Cast-Iron Cookware

Pack cast-iron pans and other cast-iron cookware in checked baggage, as TSA does not permit them in carry-on bags.

Corkscrews With Blades

A corkscrew without a blade may be permitted, but one with a blade should not go in your carry-on. Pack it in checked baggage where allowed.

Foam Toy Swords

Pack foam toy swords in checked baggage, as TSA does not allow them in carry-on bags.

Gel-Type Candles

Pack gel-type candles in checked baggage, as TSA does not allow them in carry-on bags.

Snow Globes

Small snow globes may be allowed in carry-on baggage if the liquid inside meets TSA limits. Pack larger ones in checked luggage.

Carry-On vs Checked Baggage: Why the Difference Matters

Many passengers assume that an item allowed on a plane can go in any bag. That is not always the case. Some items must remain in the cabin so the crew can respond quickly if a problem occurs. Power banks and spare lithium batteries are common examples. Other items, including heavy cookware and certain sporting equipment, belong in checked luggage because they may create security concerns inside the aircraft cabin.

What Happens If TSA Finds a Prohibited Item?

If TSA finds an item that cannot pass through the security checkpoint, your options may depend on the item and situation. You may be able to:

• Put it in checked baggage
• Return it to your vehicle
• Give it to someone who is not traveling
• Surrender it at the checkpoint

Depending on the violation, TSA may impose civil penalties of up to $17,062 per violation per person. However, an ordinary packing mistake does not automatically result in the maximum fine.

Understanding TSA carry-on rules can make airport security easier. Everyday items such as gel-filled toys, snow globes, cordless curling irons, power banks, and cookware may have specific packing requirements.

Before your flight, check whether unusual items belong in your carry-on or checked luggage. Reviewing TSA and airline guidelines before departure can help you avoid delays and move through security more smoothly.
