If you travel with camera gear, you’ll need to bring all your lithium-ion batteries into the cabin in a carry-on bag.
The U.S. Department of Transportation and Federal Aviation Administration have announced a new 'Interim Final Rule' banning the transportation of lithium-ion batteries in passenger aircraft cargo. Devices containing lithium metal or lithium-ion batteries should be kept in carry-on baggage. This includes devices with non-removable batteries, such as phones and laptops, as well as standalone batteries, including power banks and spare cameras batteries.
The major new rule was announced by U.S. Transportation Secretary Elaine L. Chao and the FAA “to strengthen safety provisions.”
