NEW YORK (AP) - Some airlines are taking extra steps to prevent a disaster in case a passenger's device powered by a lithium ion battery catches fire during flight.
At least three U.S. airlines are adding new fire-suppression equipment to fleets in case a cell phone or laptop battery overheats, catches on fire and can't be extinguished.
The issue has taken on new urgency following incidents of overheating Samsung Galaxy Note 7 phones, including one on a Southwest Airlines flight earlier this month.
The Federal Aviation Administration has taken the unusual step of warning passengers not to use or charge the devices while on board and not to stow them in checked luggage.
