Transporting electronic cigarettes and vaping devices on aircraft requires strict adherence to TSA regulations primarily focused on battery safety.
Carry-On Only: Essential Battery Rule
TSA prohibits e-cigarettes, vape pens, vaporizers, and all spare lithium batteries in checked baggage. This rule applies regardless of device status (on/off). These items must be placed in carry-on luggage or on your person.

Specific Guidelines
- Device Handling: Keep devices easily accessible for potential inspection. Separate devices from your primary bag when placing them in screening bins.
- Battery Precautions: Prevent accidental activation. Remove batteries if possible or lock the device’s power button. Use protective cases for loose batteries.
- E-Liquids: Bottles of e-liquid must comply with TSA’s liquids rule: containers holding 3.4 ounces (100 milliliters) or less per item, placed inside a single, clear, quart-sized, zip-top bag. Larger bottles must be packed in checked luggage.
- Charging: Charging devices during flight is strictly prohibited.
Usage Ban on Aircraft
Using e-cigarettes onboard any U.S. commercial flight is illegal under FAA regulations. This includes both vaping and charging. Attempting to vape in airplane lavatories will trigger smoke alarms.
Key Considerations
- Airline Policies: While TSA governs security screening, individual airlines may have stricter policies. Always consult your specific carrier’s rules before flying.
- International Travel: Vaping laws and regulations vary significantly by country. Some nations ban e-cigarettes entirely. Research destination and transit country laws meticulously to avoid confiscation or legal penalties.
- Penalties: Violating TSA rules can lead to confiscation of items, fines, delays, and potential referral to law enforcement.
