Hoverboards not welcome on Air Canada, WestJet or big U.S. airlines

Hoverboards one of the Christmasseason's hottest gifts arenot going anywhere by air this year.

Air Canada, WestJet and three major U.S. airlines have banned the boards also called self-balancing scooters or mini-Segways from both carry-on and checked baggage.

The concern is that the lithium-ion batteries that power the hoverboard can catch fire.

The U.S. Consumer Product Safety Commission is investigating at least 10 reports of hoverboard fires.

Chris Brown, Justin Bieber and other celebrities have beenpictured trying out the scooters, andvideos of hoverboard prowess and mishaps are going viral, adding to the popularity of hoverboards as a holiday gift.

Just don't try to carry it by air.

Air Canada banned them as of Dec. 8. WestJet and JetBlue also have bans. The three largest U.S. airlines Delta Air Lines, American Airlines and United Airlines announced on Thursday that they would not carryhoverboards.

"As a precautionary measure effective December 8, 2015, Air Canada no longer accepted small, lithium-battery powered vehiclesas checked or carry-on baggage given safety risks associated with the size of thebatteries that power them. These items are commonly referred to as hoverboards, electric skateboards, airwheels, mini-Segways and balance wheels," Air Canada said in a statement.

Lithium-ion batteries are blamed for some laptops and cellphones catching fire and caused a fire in the cargo hold of a UPS jet that crashed five years ago.

One Canadian distributor of a hoverboard says the devices became popular so quickly that poorly made knockoffs have flooded the market.

The devices aren't bound by any regulations, says Sean Kane of the U.S. Safety Institute.

"You really don't know how well they're designed, how well they're going to function and what safety defects they can be introducing," he told CBC News.
