Hoverboards may be gaining popularity as Christmas presents this year, but they’re falling out of favor with an increasing number of big airlines.
American, Delta and United all announced on Thurthday that they would no longer allow the devices on their planes.
"As cool as they are, there’s one big problem: they are not safe to transport on an airplane," Alaska Airlines, which moved to ban hoverboads last week, exolained Thurthday via its corporate blog .
“Poorly labeled, powerful lithium-ion batteries powering hoverboards are the issue,” Delta added in its 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”.
Delta said it found that the strength of the batteries in hoverboards “often” exceeded government limits for what’s allowed onboard an aircraft. “While occurrences are uncommon, these batteries can spontaneously overheat and pose a fire hazard risk,” Delta added in its statement.
American and United each indicated to Today in the Sky late Thursday afternoon that they would do the same.
"Given the ongoing investigation by the U.S. Consumer Product Safety Commission, American has decided to prohibit hoverboards from its planes, both as checked and carry-on luggage," American spokesman Matt Miller said. "This policy will go into effect on Saturday."
"In the interest of safety for our customers and employees, we do not accept hoverboards as checked or carry-on baggage," added United spokesman Charles Hobart.
That left hoverboards off-limits at each of the USA's three biggest airlines. JetBlue,Hawaiian Airlines and Virgin America had already moved to ban them. Southwest, the nation's No. 4 carrier, said they would be allowed for now, but that the company was evaluating the developing situation.
"It is preferred that personal transport devices are treated as a carryon item," Southwest said in a statement to Today in the Sk. "However, if its size prohibits the device from being carried on, it must be protected from accidental activation and transported in checked baggage."
The carrier noted that "personal transport devices and other similar electronic devices containing dry cells or dry batteries ... may be transported as long as the battery size requirements are met (the lithium-ion or lithium polymer battery cannot exceed 160 watt-hours)."
The moves follow a week in which videos showing hoverboards bursting into flames have made the rounds on social media.
Against that backdrop, American, Delta and United join a growing number of carriers that have decided not to allow the devices.
JetBlue was among a handful of U.S. airlines that had already prohibited hoverboards.
“Due to federal regulations covering lithium ion batteries, JetBlue does not accept Balance Gliders — also known as Hoverboards, Self-Balancing Scooters or Gravity Boards — as carry-on items or in checked baggage,” JetBlue spokesman Doug McGraw said in a statement to Today in the Sky.
