7 Critical Mistakes To Avoid When Packing A Curling Iron For Your Next Flight (TSA & FAA Rules 2025)

Planning your travel beauty routine for a trip in late 2025 or early 2026? You absolutely need to know the updated regulations for packing your hair styling tools. The rules for carrying a simple device like a curling iron, flat iron, or hair straightener on a plane have become significantly stricter in recent years, especially concerning cordless models.

As of today, December 13, 2025, the Transportation Security Administration (TSA) and Federal Aviation Administration (FAA) guidelines are clear: your packing strategy must be dictated by the power source of your device—whether it’s a standard corded tool, butane-fueled, or powered by a lithium-ion battery. Failing to follow these specific rules can result in your expensive hair tool being confiscated at the security checkpoint, ruining your travel plans before you even board the aircraft.

The Definitive 2025 Guide to Flying With Corded, Butane, and Lithium Curling Irons

The single most important factor determining where you can pack your curling iron is its power source. Standard corded electric tools are essentially unrestricted, but any cordless hair tool is classified as a hazardous material due to the risk of fire from gas cartridges or lithium batteries. This distinction is what trips up most travelers.

1. Corded Electric Curling Irons and Hair Straighteners (The Easy Ones)

This category includes your standard plug-in models. These are the simplest to travel with and have the fewest restrictions under current TSA and FAA guidelines. The rules are straightforward:

• Carry-On Baggage: Yes. Corded electric curling irons are permitted in your carry-on bag.
• Checked Baggage: Yes. They are also permitted in your checked luggage.
• Key Consideration: While the tool itself is fine, pay attention to the voltage. If traveling internationally, ensure your device is dual voltage (110V/220V) or remember to pack a suitable travel adapter and voltage converter to prevent damage.

The lack of restriction is because the risk of accidental activation or fire is minimal once the device is unplugged. They are treated like any other small electronic appliance.

2. Butane-Fueled or Gas Cartridge Cordless Curling Irons (The Restricted Category)

This is where the rules become critical. Butane and other gas-fueled curling wands are classified as dangerous goods by the International Air Transport Association (IATA) and are subject to strict regulations by the TSA and global aviation bodies like the European Union Aviation Safety Agency (EASA). The fire risk from the gas cartridge is the primary concern.

• Checked Baggage: ABSOLUTELY NOT. Butane-fueled curling irons are strictly banned from checked luggage. TSA officials will confiscate these items if found in your suitcase.
• Carry-On Baggage: Yes, but with strict conditions. You are permitted to bring one (1) butane curling iron per person in your carry-on bag only.
• Mandatory Safety Cover: The device must have a safety cover securely fitted over the heating element to prevent accidental activation during the flight.
• Spare Cartridges: Spare gas or butane cartridges are generally prohibited in both carry-on and checked luggage. You must only travel with the cartridge installed in the device.

This is a common packing mistake. Many travelers assume they can check the device, but the flammable nature of the gas cartridge necessitates it remain in the cabin where any potential issue can be immediately addressed by the flight crew.

3. Lithium-Ion Battery Cordless Curling Irons (The New Standard)

Cordless hair tools powered by rechargeable lithium-ion batteries—like many popular models from brands such as Dyson, T3, and various travel-sized ceramic tools—are also heavily regulated. This is due to the inherent fire risk associated with lithium batteries, which can overheat and combust (thermal runaway). The FAA and TSA mandate that all spare lithium batteries and most lithium-powered devices must be kept in the cabin.

• Checked Baggage: ABSOLUTELY NOT. Cordless curling irons containing lithium batteries are prohibited from checked luggage.
• Carry-On Baggage: Yes, but with strict conditions. They must be placed in your carry-on bag.
• Activation Prevention: The device must be protected from accidental activation. This usually means the battery must be removed, or the device must have a built-in safety feature (like a lock switch or a removable/isolated heating element) to prevent it from turning on during transit.
• Watt-Hour (Wh) Rating: For international travel, the battery rating is key. Most consumer electronics must not exceed a 100 Wh rating, though the vast majority of hair tools fall well below this limit. Always check the battery specifications if you are unsure.

The key takeaway for cordless devices is simple: if it has a battery or a gas cartridge, it belongs in your carry-on bag and must be secured to prevent it from turning on.

4 Essential Tips for Smooth TSA Screening with Your Hair Tools

Beyond the primary rules, incorporating these best practices will ensure your journey through the airport security checkpoint is as fast and stress-free as possible. These tips apply to all hair styling equipment, including hair dryers, flat irons, and curling wands.

1. Always Use a Heat-Resistant Pouch or Safety Cover

Even for corded tools, a heat-resistant travel pouch is an essential item. It protects the rest of your luggage from residual heat if you pack the iron immediately after use. For butane and lithium devices, a secure safety cover over the heating element is a non-negotiable TSA requirement for carry-on. This prevents the device from turning on and causing a fire hazard in the enclosed space of your bag.

2. Know Your Voltage and Pack a Converter

If you are traveling from the US (110V) to Europe or Asia (220-240V), a standard 110V curling iron will likely short-circuit and burn out when plugged into a foreign outlet. Always check for the "dual voltage" label on your device. If it is not dual voltage, you must pack a proper voltage converter, not just a simple plug adapter. This is a common oversight that leads to damaged electronics.

3. Declare Questionable Items to the Airline and Security

If you are traveling with a unique or older model of cordless hair tool, it is always a good practice to briefly inform the security officer during the screening process. Simply stating, "I have a cordless curling iron with a safety lock in my carry-on," can expedite the process and prevent a full, unnecessary search of your bag. This transparency is key to smooth airport operations.

4. Separate Cordless Batteries Where Possible

For lithium-powered devices that allow for battery removal, it is highly recommended to remove the battery and place it in a small, separate plastic bag or case in your carry-on. This makes the item clearly visible to security scanners, demonstrating compliance with the rule to prevent accidental activation. This extra step helps mitigate the risk of a thermal event and speeds up the screening process for the security staff.

Final Travel Checklist: Curling Iron Edition

Navigating the rules for hair styling tools is all about recognizing the difference between corded and cordless technology. The TSA and FAA are primarily focused on fire prevention, which is why butane and lithium-powered devices are treated like hazardous materials and must be kept in the passenger cabin.

To summarize your packing strategy for your next international flight or domestic journey:

• Corded Iron: Carry-on or Checked Bag. (Remember your dual voltage and travel adapter!)
• Butane Cordless Iron: Carry-on ONLY (1 per person). Must have a safety cover. No spare cartridges.
• Lithium Cordless Iron: Carry-on ONLY. Must be protected from accidental activation (lock or battery removal).

By following these clear, updated 2025 guidelines, you can ensure your favorite ceramic curling wand or titanium flat iron makes it safely to your destination, allowing you to maintain your perfect hairstyle throughout your travels.
