Carrying Electronic Cigarettes on Flights
General Rule: Yes, electronic cigarettes (e-cigarettes), vapes, vape pens, e-cigars, e-pipes, and other personal vaporizers can generally be carried on flights, but with specific and important restrictions.
Key Regulations:

- Carry-on Baggage Only: Electronic cigarettes and vaping devices, including any spare lithium batteries, must be transported in your carry-on baggage. They are strictly prohibited in checked baggage due to the fire risk associated with their lithium batteries.
- Prohibition of Use and Charging: Using or charging electronic cigarettes or vaping devices is not permitted onboard the aircraft at any time. This includes during boarding, in flight, and while disembarking.
- Accidental Activation: Ensure your device is protected from accidental activation. Some airlines may require devices to be completely switched off.
E-Liquids:
- E-liquids are subject to the standard restrictions for liquids, aerosols, and gels (LAGs) in carry-on baggage.
- This typically means that containers must be 100ml (3.4 ounces) or less. All such containers must fit comfortably within a single, transparent, resealable plastic bag, usually with a maximum capacity of 1 liter.
Important Considerations:
- Airline and Country Variations: Regulations can vary significantly between airlines and countries. Some countries have strict laws regarding the possession, use, or importation of e-cigarettes, including outright bans. Always check the specific policies of your airline(s) and the local laws of your destination and any transit countries well before your travel date.
- Security Screening: You may be required to present your e-cigarette and e-liquids separately for security screening.
Failure to comply with these regulations can result in confiscation of the device, denial of boarding, fines, or other penalties.
