The three largest U.S. airlines are banning hoverboards because of the potential fire danger from the lithium-ion batteries that power the devices.
Delta Air Lines, American Airlines and United Airlines said Thursday they are banning hoverboards in checked or carry-on luggage. JetBlue Airways has already prohibited them.
Hoverboards are motorized, two-wheel, skateboard-sized scooters that users stand on. They have been a hot gift item at some retailers.
United's ban took effect immediately, Delta's ban takes effect Friday and Fort Worth-based American bans hoverboards as of Saturday.
Dallas-based Southwest Airlines prefers that passengers with a hoverboard or other items that use lithium batteries carry them on the plane, but a spokeswoman said the airline is discussing the topic further.
