According to the TSA, hand warmers are allowed in both carry-on and checked bags without any restrictions, though transporting them inside their original packaging is preferred.

Hand Warmers That Are Acceptable

Air-Activated Hand Warmers

Air-activated hand warmer? How cool is that?! Air-activated hand warmers are battery-powered thermoelectric heat pads that provide thermal energy via electricity.

This means that you won't have to worry about running out of batteries or using lighter fluid anymore. You simply plug them into any USB port and you're done!

These hand warmers come in various shapes and sizes. Some are big enough to fit two hands, while others are small enough to fit only one hand.

Choose a hand warmer that is comfortable. You should not feel pain during the flight. If they hurt, remove them immediately.

Also, never leave your hand inside the bag because you might burn yourself. Lastly, hand warmers that require liquid fuel may catch fire if exposed to liquid and high temperatures. Avoid liquids during travel.

Battery Powered Hand Warmers

You'll find a wide array of rechargeable battery-powered hand warmers out there. Some are made from silicone, some are made from rubber, and some are made from a combination of materials.

There are even ones with a retractable cord and others without a retractable cord. You'll find them in all kinds of colours and designs. While they vary quite a bit, they generally work in pretty much the same way.

Here's a quick rundown of the main features.

They typically include a small plastic container that holds a stack of batteries. The user removes the batteries from the container and inserts them into the warmer itself.

Once inserted, the warmer powers on until the battery runs low. At this point, the user simply reinserts another battery pack.

This process happens automatically. The light turns green after the last battery pack has been used. The light will remain green until it reaches zero power. Then the light turns yellow, and finally red once it hits zero power.

A timer can also be attached to most models which makes the warmth last longer. This timer helps prevent the user from forgetting about the warmer. Many users have found that a timer lasts anywhere between 30 minutes and 4 hours depending on the size of the warmer.

Crystallization Hand Warmers

Crystallization hand warmers are reusable hand warmers that melt at body temperature and release warmth through the heat released during the melting action.

Because they are made out of chemicals, they don't qualify as liquids for travel purposes, so they won't have any issues passing through airport security.

However, they only last for 30 minutes, so be prepared to boil them after use.

These hand warmers can be great for use in flight situations, especially if you have a bag of water with you that you'd prefer to keep cold instead of boiling on the stovetop.

You just need to remember to boil the crystals after using them.

There are a lot of different types of hand warmers available, including ones that work via thermal pads, heated gel packs, and heating blankets.

Some models also include small compartments where you can store tissues, mints, etc., and others have built-in pockets for storing your phone and wallet.

Hand Warmers That Are Not Allowed

Some airlines prohibit certain items from being brought onto planes. One of those items is charcoal hand warmers. These hand warmers used to be very common. However, they were banned because they pose a safety hazard to passengers and have now been replaced by battery-powered hand warmers.

Lighter Fluid Hand Warmers

As far as the TSA goes, using lighter fluid as fuel to heat your hands is not allowed on planes.

And since there are no approved alternatives to keep your hands warm during flights, you'll need to find another alternative if you want to bring lighter fluid onto planes.

These are similar to charcoal hand warmers but use lighter fluid as fuel.

Because they use lighter fluid, you can only fit two of these in your carry-on bag. But unlike charcoal hand warmers, these do not require batteries. Instead, you simply light them up, wait 10 minutes, and they're ready to use. 

Are Rechargeable Hand Warmers Allowed On Airplanes?

Hand warmers are great for keeping hands nice and toasty during long flights.

However, there are certain hand warmers that are not allowed on aeroplanes because they tend to explode. These include rechargeable ones that contain lithium-iron phosphate batteries.

Lithium iron phosphate batteries can become overheated during the flight if placed directly next to electronic devices, and they can catch fire.

Because of this risk, the Transportation Security Administration and the Federal Aviation Administration regulate the transportation of similar items and they do not consider them hazardous objects.

How Should You Pack Your Hand Warmers In Your Bag?

While hand warmers made of wool or fleece are considered safe, they may melt down if exposed to high heat. As a result, they should only be transported on airlines in their original packaging.

But you extra precautions while packing and keep in mind the temperature they are going to be in.
