The Basics of Airline Regulations
Airlines follow guidelines set by the International Air Transport Association (IATA) and the Federal Aviation Administration (FAA) concerning the carriage of batteries. The general rule prohibits carrying e-cigarettes with lithium batteries in checked baggage because of the potential fire hazard they pose. Instead, passengers are required to pack e-cigarettes in their carry-on luggage. This regulation helps mitigate risks, as cabin crew can quickly respond to fires or smoke originating from cabin luggage.
Understanding Battery Regulations
Both the IATA and FAA have strictly stipulated that lithium-ion and lithium-metal batteries must remain out of the cargo hold, as minute damages could lead to dangerous situations. E-cigarettes usually contain lithium batteries which, if packed in checked luggage, could become a hidden source of danger.
It is important to note
that simply bringing your e-cigarette on board does not guarantee compliance with every airline’s rules. Individual airlines may implement additional requirements, and it’s prudent to double-check these before travel. When in doubt, consult your airline’s website or representative.
Potential Risks of Incorrect Packing
Packing e-cigarettes in checked luggage is not advisable because improper placement could lead to accidental activation and overheating. Thermal runaway—a phenomenon where increased temperature leads to a rapid and uncontrollable increase in battery temperature—could occur. Such events are rare but serious enough to warrant precaution. Any heat source, notably an activated or damaged battery, poses an elevated risk in enclosed spaces such as aircraft luggage compartments.
Other Considerations
Ensure e-liquids and vaping materials comply with the general liquid regulations for flights. Typically, airlines require that any liquid items exceeding 100ml be packed in checked luggage, but with batteries needing to stay in the cabin, travelers must consider how to correctly distribute their vaping paraphernalia. Travelers should also check local laws and regulations regarding e-cigarettes at their destination to avoid any legal inconvenience.
Do You Need Special Storage Equipment?
For e-cigarettes, using cases specifically designed to transport and protect lithium batteries is recommended. These cases help reduce movement and nascent pressure on the battery terminals, thus minimizing chances of accidental activation or damage. While not obligatory, possessing a case for travel is a sensible precaution.
What If Your E-Cigarette Is Confiscated?

Despite extensive preparation, there remains a possibility your e-cigarette could be confiscated. Confiscation generally occurs if passengers fail to comply with flight crew instructions or when travelers neglect to pack the device properly. Always ensure the device is stored correctly, battery properly detached, if required, and fully informed of airline rules.
FAQ
- Can I pack e-liquids in checked baggage?
Yes, but ensure the e-liquid containers are leak-proof and properly sealed to prevent spillage, adhering to airline policy on liquid container sizes. - Why can’t e-cigarettes be packed in checked bags?
E-cigarettes pose a fire risk due to their lithium batteries, which are prone to overheating, hence must be carried in the cabin where crew can promptly respond to issues. - Are there exceptions for flights where e-cigarettes can be checked?
Generally no, as international and federal regulations prohibit such practices to ensure passenger safety, although always check specific airline policies for any potential exceptions.
