The U.S. Federal Aviation Administration, which already bans flammables and explosives in checked airplane baggage, is now advising airlines to consider the potential fire risk from e-cigarettes.

E-cigarettes typically heat liquid nicotine into an inhaled vapor by using lithium-based batteries, which in some cases can overheat and cause fires. The FAA sent a Safety Alert for Operators to airlines Friday about the devices. While voluntary and nonbinding, typically most airlines follow such guidance from the FAA.
