Do Your Passengers Pack Their E-Cigarettes?
FAA Safo 15003 highlights the risks of placing e-cigarettes in checked bags.

The FAA released a new safety alert for operators—SAFO 15003—to address the fire hazard potential of e-cigarettes packed in baggage stored in the cargo hold of an aircraft. Research has identified a fire risk should the e-cigarette heating element either be left on or be switched on accidentally. Currently, there is no regulation that specifically prohibits packing e-cigarettes.
