Airlines worry that battery-powered devices like hoverboards, laptops, and even luggage could become a fire risk. Starting January 15th, American Airlines passengers will be banned from checking “smart” luggage if their batteries can’t be removed. Delta followed close behind with a similar restriction while United and Southwest Airlines expressed an ongoing review of policy. Featuring USB ports for charging, “smart” luggage is a growing sector of the luggage market. Approved screwdrivers are on offer from the TSA for on-site battery removal.
