The three biggest U.S. airlines — American, United and Delta — will no longer allow hoverboards on flights.
The ban extends to both carry-on and checked luggage, so if you were hoping to bring your battery-powered rolling contraption home for the holidays, think again.
United’s ban on the devices is effective immediately, Delta’s begins on Friday, American’s on Saturday.
“Poorly labeled, powerful lithium-ion batteries powering hoverboards are the issue,” Delta said in a statement. “Delta reviewed hoverboard product specifications and found that manufacturers do not consistently provide detail about the size or power of their lithium-ion batteries.”
The airline’s investigation into the devices also found the some brands’ batteries contain more watt hours than the government permits on aircraft. Delta found that the devices varied so much that a total ban was the best option.
“While occurrences are uncommon, these batteries can spontaneously overheat and pose a fire hazard risk,” Delta’s statement reads.
The airline also took the opportunity to remind passengers that spare batteries must be packed in carry-on baggage, and each traveler can carry no more than two.
The big three join JetBlue, Virgin America, Alaska Airlines and Frontier in banning hoverboards from checked and carry-on baggage. Southwest is the only major airline that allows them still — with restrictions: A device with a battery under 160 watt hour can be stored in checked luggage. But that could change soon, the way things are going.
“Employee and passenger safety remains the airline’s top priority,” Delta said, “driving Delta to disallow hoverboards and all lithium battery powered self-balancing personal transportation devices in carry-on and checked baggage effective Dec. 11.”
