Electronic cigarette airport security regulations vary, but here’s a concise overview:
Carry-On vs. Checked Baggage
- E-cigarettes and vaping devices: Must be carried in carry-on baggage. They are prohibited in checked baggage.
- E-liquids: Generally allowed in carry-on baggage in travel-sized containers (under 100ml or 3.4 ounces) and must comply with liquid restrictions. Larger quantities should be placed in checked baggage.
Why the Restrictions?
The primary reason for these restrictions is the fire risk associated with lithium batteries. E-cigarettes contain lithium batteries, which can overheat and potentially cause fires, especially during air travel. Keeping them in the cabin allows flight attendants and passengers to respond quickly to any incidents.

TSA Guidelines
The Transportation Security Administration (TSA) allows e-cigarettes and vaping devices in carry-on bags. However, they recommend taking steps to prevent accidental activation during transport. This may include:
- Turning off the device.
- Locking the device.
- Placing the device in a protective case.
Airline-Specific Rules
Always check with your specific airline for their policies regarding e-cigarettes. Some airlines may have stricter rules than the TSA. Policies can vary regarding the use of e-cigarettes on the plane (usually prohibited) and the charging of devices during the flight.
International Travel
Be aware that regulations regarding e-cigarettes can vary significantly from country to country. Some countries have banned the sale or possession of e-cigarettes altogether. It’s your responsibility to research and comply with the laws of your destination.
Tips for Traveling with E-cigarettes:
- Empty tanks: Consider emptying tanks to prevent leakage due to changes in air pressure.
- Original packaging: Transport e-liquids in their original packaging whenever possible.
- Declare: Be prepared to declare your e-cigarette and e-liquids at security checkpoints.
Following these guidelines can help ensure a smooth and compliant travel experience with your electronic cigarette.
