TSA Rules for Curling Irons in Carry On Bags
The Transportation Security Administration allows corded and cordless curling irons in carry on luggage. According to the TSA official website, curling irons and flat irons are permitted in both carry on and checked bags without restrictions on wattage or size. If your device has a butane or propane cartridge, it must be protected with a cap and is allowed only in checked bags, not in carry on. TSA officers may request you to power on the device at the checkpoint to verify it is a personal grooming tool and not a prohibited item.

Packing your curling iron in a hard case or wrapping the cord tightly reduces the risk of damage during inspection. TSA guidelines note that devices with removable batteries should be handled carefully to avoid accidental activation. The agency does not set a specific size limit for personal grooming irons in carry on, but oversized items may be subject to additional screening. Always ensure the curling iron is cool and free of any flammable residue before placing it in your carry on bag.
Airline Policies and In Flight Use
Major U.S. carriers such as Delta Air Lines, United Airlines, and American Airlines follow TSA standards and allow curling irons in carry on bags. Delta explicitly states that personal care devices like curling irons and straighteners are permitted in the cabin and may be used during the flight only when seated and with the airline crew's approval. United Airlines and American Airlines similarly permit carry on grooming devices but restrict their use during taxi, takeoff, and landing. For international carriers, including Emirates and British Airways, the general rule is that curling irons are allowed in carry on, but in flight use may be prohibited unless cabin crew give permission.
Some low cost carriers, including Southwest Airlines and Spirit Airlines, also allow curling irons in carry on without special restrictions. Southwest notes that personal items such as hair styling tools must be stowed during critical phases of flight. Budget airlines may enforce stricter cabin rules, so checking the specific carrier policy before travel is recommended. Airlines may also impose size limits on personal items that include your carry on bag, so a compact curling iron can help you stay within those limits.
Battery Powered and Smart Curling Irons
Rechargeable curling irons with lithium ion batteries are allowed in carry on bags under current FAA and TSA rules. The FAA requires that spare lithium batteries, including those in personal devices, be carried in carry on luggage rather than checked baggage to reduce fire risk. Devices with non removable batteries must be protected against accidental activation, and the battery watt hour rating should generally not exceed 100 Wh without airline approval. For high capacity batteries between 100 Wh and 160 Wh, airline approval is required, and a maximum of two spare batteries may be carried per passenger.
Smart curling irons with Bluetooth connectivity or digital displays are treated as personal electronic devices and must be packed so they cannot shift during turbulence. The FAA Modernization and Reform Act of 2012 and subsequent guidance from the FAA and TSA continue to treat personal grooming devices with batteries as safe for carry on when properly packed. If your curling iron uses a butane cartridge, it is prohibited in carry on and must go in checked luggage with the valve protected.
