Traveling with vape pens requires strict adherence to airline safety regulations. Here’s a clear breakdown of the key rules:
Carry-On Only; No Checked Bags
Electronic cigarettes, vape pens, e-cigars, and other personal vaporizers must be carried in your hand luggage or on your person. They are prohibited in checked baggage due to fire risks associated with their lithium batteries, especially under pressure changes.

Lithium Battery Restrictions
Pay close attention to the battery’s specifications:
- Must be carried onboard: Batteries cannot be in checked baggage.
- Power Limits: Batteries must typically be under 100 Watt-hours (Wh). Spare batteries should be individually protected in cases or bags.
- International Variations: Some countries (e.g., South Korea) have stricter rules, requiring batteries/vapes in transparent bags visible during flight and limiting quantities (e.g., max 5 units under 100Wh). Always check your destination’s regulations.
E-Liquid Restrictions
Liquid containers (bottles, pods, tanks) must comply with cabin baggage liquid rules:
- All liquids must be in containers of 100ml (3.4 ounces) or less.
- All containers must fit within a single, transparent, resealable plastic bag (approx. 1-quart size).
- Prevent Leaking: Empty tanks/pods if possible. Store liquid bottles and filled pods upright in the plastic bag. Placing pods in tissue paper upside down can help minimize leakage.
Security Screening Protocol
Declare your vape gear when approaching airport security. Place the device, spare batteries, and your clear liquid bag separately into a security bin for X-ray screening.
Absolute In-Flight Ban: No Use
Using electronic cigarettes onboard any flight is strictly forbidden and illegal. Reasons include:
- Potential to trigger sensitive aircraft smoke detectors.
- Nuisance to passengers and crew.
- Risk of fire in the confined cabin space.
Consequences are severe: Users face potential arrest, fines, civil penalties, placement on airline “no-fly” lists, and criminal charges in serious cases.
Essential Pre-Flight Checklist
- Confirm Airline & Destination Rules: Check specific policies for your carrier and arrival country/national regulations.
- Carry-On Only: Pack vape device, batteries, and liquids in hand luggage.
- Secure Liquids: Ensure all e-liquids are in ≤100ml containers within a single quart-sized transparent bag. Keep pods secure.
- Protect Batteries: Carry spares in individual protective cases. Know your battery capacity (Wh).
- Declare at Security: Present all vape-related items openly during screening.
- Never Use Inflight: Understand and respect the absolute ban on use during the entire journey, from boarding to disembarkation.
