Most major international airlines permit electronic cigarettes in hand luggage under aviation safety regulations, but specific rules vary. Key guidelines ensure compliance and avoid confiscation or penalties.
General Packing Rules
E-cigarettes must be carried in hand luggage only, as lithium batteries pose fire risks in cargo holds. Include vaping devices, spare batteries, and chargers in your carry-on. Never place them in checked baggage.

Battery and Device Precautions
- Remove batteries from devices or protect against short circuits (e.g., store in original packaging or plastic cases).
- Spare lithium batteries are capped at 100 watt-hours per battery; carry no more than two.
E-Liquid Regulations
- Follow liquid restrictions: bottles no larger than 3.4 ounces (100ml) each.
- Place all e-liquid containers in a transparent, resealable plastic bag for security screening.
International Compliance
Destination laws may prohibit vaping entirely; research local regulations. Always declare e-cigarettes if requested during security. In-flight use is strictly prohibited.
Pre-Departure Actions
- Confirm airline policies in advance.
- Pack extras like charging cables discreetly.
