Vaping on a plane: The complete guide 2026
Electronic cigarettes must always be carried in your carry-on luggage, never in checked baggage, as their lithium battery poses a fire risk which is prohibited in the cargo hold by airline regulations. Your e-liquids follow the liquid rules for cabin baggage: maximum 100 ml per bottle, stored in a transparent one-liter bag.
Vaping during the flight and charging the device during the journey are strictly prohibited. According to IATA, each traveler can carry up to two spare batteries protected against short circuits, but these are still banned from checked baggage on all airlines.
| Vape item | Carry-on or hand luggage | Checked luggage |
|---|---|---|
| Electronic cigarette (box, kit, pod) | Allowed and mandatory | Prohibited |
| Lithium batteries and spare batteries | Allowed, terminals isolated | Prohibited |
| E-liquids in bottles of 100 ml max | Allowed in transparent bag | Allowed with no volume limit per bottle |
| Disposable cigarette or puff | Allowed in cabin | Prohibited |
| Vaping or charging during the flight | Prohibited on board | N/A |

Regulations for lithium batteries on planes
Lithium batteries in your electronic cigarette can only be transported in the cabin, never in checked baggage. This transport rule stems from the risk of short circuits and thermal runaway, which is difficult to control in an inaccessible cargo hold during flight. International air regulations, harmonized by IATA, apply to all airlines.
Why are lithium-ion batteries banned from checked baggage?
A damaged lithium-ion battery can ignite without external oxygen, and a fire in the cargo hold would only be detected after it has spread. In the cabin, an incident is spotted and extinguished immediately by the crew. This is why all batteries, boxes, and integrated coils must remain with you.
How many spare batteries can you carry?
Most airlines allow up to two spare batteries per traveler, provided they do not exceed 100 watt-hours. Beyond this, airline approval is required. To prevent any short circuit, the terminals of each battery must be insulated with a rigid case, a protective box, or adhesive tape. A damaged coil or battery should always be transported separately.
- Transport each battery in an individual pouch, never loose with keys or coins, to avoid short circuits.
- Turn off the device and, if the kit allows, lock the firing button before storing it.
- Keep batteries and the kit in your carry-on luggage, accessible for security checks.
Transporting electronic cigarettes in the cabin, not in checked baggage
Always store your electronic cigarette in your carry-on bag or hand luggage that you keep with you. Since lithium batteries are an integral part of the device, the entire vape follows the same rule and should never be put in checked baggage when boarding. If you are also traveling with a power bank, see our rules for taking a power bank on a plane.
Where should you store your electronic cigarette during a flight?
Place the e-cigarette in your cabin bag, ideally in a dedicated pouch or protective case. Keep the box, pod, each battery, and the coil within reach. To organize batteries, bottles, and cables, a dedicated kit saves time at the security checkpoint. A disposable cigarette or puff follows exactly the same transport rule.
Can you put your vape and batteries in checked baggage?
No, putting your vape or batteries in checked baggage is strictly prohibited on all airlines. A suitcase containing a vape device checked in the hold may be held, opened, or even delay the flight while the non-compliant item is removed.
If you're unsure about what's allowed on board, our article on prohibited items in carry-on luggage details the transport rules item by item.
Rules for e-liquids in cabin and checked baggage
In the cabin, each e-liquid bottle must contain a maximum of 100 ml and fit into a transparent, re-sealable plastic bag of one liter. In checked baggage, no volume limit per bottle applies, but transporting your e-liquids separately from the vape remains good practice to avoid any liquid leaks.
How to apply the 100 ml rule?
Group all your bottles, vials, and nicotine boosters into a single transparent bag, presented separately at security control. A bottle of propylene glycol or vegetable glycerin larger than 100 milliliters will be refused in the cabin, regardless of its fill level. The 100-milliliter rule also applies to nicotine salt and any pre-filled cartridge.
The logic is identical to that of any liquid on a plane: the volume indicated on the container takes precedence, not the quantity actually present inside.
How to avoid a liquid leak in the cabin?
Depressurization at altitude causes air to escape from the clearomizer and leads to liquid leaks. To prevent this, empty the tank or fill it to a minimum before takeoff. Depressurization affects the coil and the drip tip: close the atomizer tightly and transport the e-cigarette in an upright position.
- Empty the clearomizer tank or leave it almost full, never half-empty, to anticipate depressurization.
- Close the airflow and the filling cap to limit liquid leakage.
- Store bottles and clearomizer in a zip-lock bag in case of liquid seepage.
Prohibition of vaping and charging during the flight
Vaping is completely prohibited on all commercial flights, including in aircraft lavatories. Vaping inflight is equivalent to smoking on board and can result in a fine, a report, or even legal action. Charging your electronic cigarette via an onboard USB port is also forbidden.
What are the risks of vaping in the lavatories?
Airplane lavatories are equipped with smoke detectors that react to vapor just like to traditional cigarettes. Triggering this smoke detector disrupts the journey and can lead to a financial penalty, disembarkation upon arrival, and inclusion in the airline's passenger file. The smoke detector makes no distinction between vapor and smoke; no tolerance exists on this point.
Why can't you charge your e-cigarette on board?
Recharging a lithium-ion battery during a flight increases the risk of overheating and short-circuiting in a confined space. Airlines therefore prohibit plugging a box or a battery into the cabin's outlets. Travel with charged equipment and the device turned off until disembarkation.
Passing security and customs with a vape
At security control, take your electronic cigarette and batteries out of your bag to present them separately in a tray, like any electronic device. X-ray screening is not an issue, but a security agent may request a visual inspection of the kit and bottles.
How to make passing through the checkpoint smoother?
Place the box, batteries, and the transparent e-liquid bag in an easily accessible pouch, at the top of your carry-on luggage. Well-organized equipment reduces questions from the security agent and speeds up boarding.
A dedicated kit or organizer, found in our travel accessories, keeps batteries, cables, and bottles grouped and ready for inspection.
Airline policies: Air France, easyJet, Ryanair, Transavia
All airlines require electronic cigarettes to be carried in the cabin and prohibit them in checked baggage, but some nuances exist regarding batteries and the number of accumulators. Check the official policy before boarding, as transport rules change regularly depending on the airline and type of flight.
| Airline | Electronic cigarette in cabin | Spare batteries | Vaping on board |
|---|---|---|---|
| Air France | Mandatory in cabin | Up to 2, protected terminals | Prohibited |
| easyJet | Mandatory in cabin | Up to 2, in original packaging | Prohibited |
| Ryanair | Mandatory in cabin | Up to 2 isolated batteries | Prohibited |
| Transavia | Mandatory in cabin | Up to 2, protected from short-circuit | Prohibited |
Do you need to declare your electronic cigarette to the airline?
No prior declaration is required for a vape and two batteries under 100 watt-hours on Air France, easyJet, Ryanair, Transavia, Lufthansa, or Emirates. A declaration is only necessary for high-capacity batteries.
According to IATA's traveler guide, electronic cigarettes and their spare batteries are exclusively allowed in carry-on luggage, with no known exceptions among major airlines.
Legislation of destination countries on vaping
Electronic cigarettes are prohibited in several countries, where simple possession can lead to confiscation, a fine, or even imprisonment. Always check the legislation of your destination before traveling, as airline rules do not override local customs upon arrival.
In which countries is the electronic cigarette prohibited?
Vaping is illegal or heavily restricted in Thailand, Singapore, India, Mexico, Oman, and Taiwan. In Thailand and Singapore, customs can seize equipment and impose a heavy penalty. Confiscation at customs is common, and all travelers must inquire with the official authorities of the destination country before their trip.
- Thailand and Singapore: illegal possession and import, seizure and fine at customs
- India: sale, import, and use of electronic cigarettes prohibited by law
- Mexico, Oman, Taiwan: restricted import, risk of confiscation upon entry
When in doubt about the destination, it's always better to err on the side of caution: leave your vape at home rather than risk seizure or prosecution upon arrival.

Conclusion
Traveling with an electronic cigarette boils down to three simple transport rules: device and lithium batteries always in carry-on luggage, e-liquids in 100 ml bottles in the transparent bag, and no vaping or charging on board. Protect your batteries from short circuits, empty the clearomizer well to prevent liquid leaks, and check the legislation of your destination country before each departure.
