Regulations for Electronic Cigarettes on Airplanes
Electronic cigarettes (e-cigarettes), vape pens, and other personal vaporizers are subject to specific airline and aviation authority regulations. Adherence to these rules is essential for air travel.
Key Restrictions:

- Carry-on Baggage Only: All electronic smoking devices must be transported in carry-on baggage. They are strictly prohibited in checked luggage due to the fire risk associated with their lithium batteries.
- Battery Safety: Spare lithium batteries for e-cigarettes must also be in carry-on baggage. They must be individually protected to prevent short circuits, for example, by keeping them in original retail packaging, by taping over exposed terminals, or by placing each battery in a separate plastic bag or protective pouch.
- In-Flight Use and Charging Prohibited: The use of e-cigarettes and vaping devices is forbidden on board all commercial aircraft. This prohibition includes aircraft lavatories. Charging of these devices or their batteries during flight is also not permitted.
- E-Liquids: E-liquids are subject to standard restrictions for liquids, aerosols, and gels in carry-on baggage. Typically, this means containers must be 3.4 ounces (100 milliliters) or smaller and all containers must fit comfortably within a single, clear, quart-sized, resealable bag.
Packing and Preparing Your E-cigarette for Travel
Proper preparation of your vaping equipment is crucial to comply with regulations and prevent issues during security screening or in flight.
Device Preparation:
- Ensure your device is completely turned off.
- Take measures to prevent accidental activation. This may include removing the battery if the device design allows, or using a protective case.
- If your device has removable batteries, ensure they are stored safely as per the battery safety guidelines mentioned above.
E-liquid Packing:
- Store e-liquids in securely sealed, leak-proof containers. Pressure changes in the cabin can cause leaks if containers are not properly sealed.
- Consider double-bagging e-liquid containers as an extra precaution against spills.
- Ensure the total volume and packaging of your e-liquids comply with the governing aviation security authority’s rules for liquids in carry-on baggage.
Important Considerations
Beyond the general rules, always verify specific requirements before your journey.
- Airline Policies: While aviation authorities set baseline regulations, individual airlines may impose additional or more stringent restrictions. Always check the specific policy of your airline before traveling.
- Destination Regulations: The legality and regulations concerning e-cigarettes vary significantly by country and even by region within countries. Research and understand the laws regarding e-cigarette possession, use, and importation at your destination to avoid potential legal complications. Some countries have outright bans on these products.
- Security Screening: Be prepared to present your e-cigarette and e-liquids for inspection during security screening.
