Vapes and E-Cigarettes on Planes: Rules in 2026

Vaping devices — whether rechargeable pod systems, box mods, disposables, or pen-style e-cigarettes — are among the most commonly mishandled items in airport security. The fundamental rule is simple: vapes must be in carry-on, cannot be used on the aircraft, and in some countries cannot be brought at all. Here is everything you need to know.

The Non-Negotiable Rule: Carry-On Only

All vaping devices contain lithium-ion batteries. Under IATA Dangerous Goods Regulations — which all commercial airlines worldwide must follow — lithium batteries in electronic devices are prohibited in checked baggage.

This applies to:

• Rechargeable pod systems (JUUL, Vype, Elf Bar rechargeable)
• Box mods and advanced personal vaporizers
• Disposable vapes (Elf Bar, Lost Mary, Geek Bar, etc.)
• E-cigarettes (cigalikes, vape pens)
• Nicotine pouches with embedded electronics
• Heated tobacco products (IQOS, glo)

The battery restriction cannot be waived. If your checked bag is discovered to contain a vaping device, it will be removed before the bag goes in the hold. Airlines have the right to offload your bag entirely.

If you are gate-checked (your carry-on is checked at the gate due to overhead bin space), remove your vaping devices from the bag before it is checked. Keep them on your person or in another bag you retain.

You Cannot Vape on a Plane

Vaping on commercial aircraft is prohibited by aviation law in virtually every country, including the US (FAA regulations), EU member states, UK (ATOL rules), Australia, and most others.

The prohibition is enforced the same way smoking is: no exceptions, including in lavatories. Modern aircraft smoke detectors are sensitive to vapour as well as smoke — lavatory vaping has triggered emergency responses on commercial flights.

Penalties vary by country and airline:

• Fines from hundreds to thousands of pounds/dollars/euros
• Diversion of the aircraft (rare but documented)
• Police involvement at landing
• Lifetime airline bans

There is simply no situation where vaping on a commercial aircraft is acceptable. If you need nicotine during a long flight, consider nicotine patches or gum, which are permitted.

E-Liquid Rules at Security

E-liquid is a liquid and is therefore subject to the standard liquids restriction in carry-on.

Carry-On (100ml Rule)

• Each bottle of e-liquid must be 100ml or less
• All e-liquid bottles must fit in a single 1-litre clear liquids bag
• Combined with all your other liquids (toiletries, etc.)

Most standard e-liquid bottles (10ml in the UK, 30–60ml in the US) are well within the 100ml limit. The limitation is the total 1-litre bag capacity.

Pre-filled pods and cartridges contain a small amount of liquid and do not need to be declared separately — they go in your bag as part of the device.

Checked Baggage

There is no specific liquid restriction on e-liquid in checked baggage beyond the general airline dangerous goods rules. You can pack 100ml bottles, 60ml bottles, or large 120ml+ bottles in checked baggage. Pack e-liquid in a sealed plastic bag in case of leaking (pressure changes in the hold can cause some bottles to leak).

Disposable Vapes: E-Liquid Consideration

Disposable vapes are sealed units — the e-liquid inside cannot be removed. Most disposables contain between 1ml and 20ml of e-liquid, well under the 100ml limit. They can go in your liquids bag or simply in your carry-on without being placed in the liquids bag, as the liquid is contained in the device.

Airport Security: What to Expect

Removing Vaping Devices

Vaping devices may need to be removed from your bag at security if the bag is flagged for inspection. Some airports ask for electronics to be placed in the tray; others only require laptops. Follow the instructions of the security officer.

Security Concerns About E-Liquid

Some security officers are unfamiliar with e-liquid and may question whether it is permitted. E-liquid is treated as any other liquid — the 100ml rule applies. If questioned:

• Show the bottle size (100ml or under)
• Confirm it is in your liquids bag
• Calmly explain it is e-cigarette liquid

What Will Be Confiscated

If you have an e-liquid bottle over 100ml in your carry-on (common with US-market 120ml bottles), it will be confiscated. Do not attempt to hide large bottles — they are visible on X-ray.

International Rules: Country-by-Country Restrictions

This is the most critical area for vapers traveling internationally. Several countries have outright bans on vaping products.

Countries That Ban Vaping Devices

Complete bans on import and use:

• Thailand — vaping devices are prohibited; fines up to 30,000 baht (~$800) and up to 10 years imprisonment in serious cases
• Singapore — complete ban on import and use; $1,500 SGD fines for first offense
• Cambodia — banned since 2021
• Laos — banned
• Brunei — banned
• India — banned since 2019 under PECA

Significant restrictions:

• Qatar — importation restricted; enforcement inconsistent but officially banned at customs
• UAE (Dubai, Abu Dhabi) — vaping is legal but e-liquid with nicotine has been in a legal grey area; check current rules before travel
• Japan — nicotine-containing e-liquid is illegal to sell but personal import for personal use has been tolerated; heated tobacco (IQOS) is widely available and legal

Partial or regional bans:

• Australia — nicotine e-liquid legally requires a prescription; bringing personal supplies is in a grey area; practically, bringing a personal vaping device for personal use is generally not prosecuted but is legally ambiguous
• Brazil — sale and advertising banned but personal use tolerated
• Mexico — sale banned but possession for personal use generally tolerated

Countries Where Vaping Is Legal With Restrictions

UK: Legal, regulated, e-liquid sold in 10ml bottles max (TPD), nicotine content max 20mg/ml.

EU: Similar to UK under the Tobacco Products Directive.

USA: Legal for persons 21+. PMTA regulations mean many products have uncertain legal status but travelers are not personally at risk.

Canada: Legal for persons 18+ (or 19+ in some provinces).

New Zealand: Legal, regulated.

Tips for Vapers Flying Internationally

Research destination laws before booking. What is a minor inconvenience (having a device confiscated) in some countries is a serious legal risk in others. Thailand's vaping ban carries real criminal penalties.

Keep devices accessible in carry-on. Place your vaping device in an easily accessible pocket of your carry-on so you can retrieve it quickly if gate-checked and need to remove it.

Use a case for devices and pods. A dedicated vaping travel case prevents device damage and keeps pods from leaking in the pressure changes of flight. Many purpose-built cases are available.

Bring nicotine alternatives for long flights. Even if you are a daily vaper, a 12-hour flight without nicotine is manageable with patches or gum. This eliminates the temptation to use a device on board.

Pack e-liquid in checked bags where possible. Liquid rules in carry-on are easy to exceed if you use high-VG liquids or carry multiple flavours. Put the bulk of your e-liquid in checked baggage (in a sealed plastic bag) and carry only what you need for the journey in your liquids bag.

Declare at customs honestly. Some countries (like the UK) allow personal quantities of tobacco products without duty; vaping products are in a similar category. If you are bringing a vape into a country where it is restricted, declare it and accept the consequences rather than risk a smuggling charge.

Heated Tobacco Products (IQOS, glo)

Heated tobacco products like IQOS use a separate category from vaping devices — they heat real tobacco rather than e-liquid. The battery rules are the same: carry-on only, cannot be used on aircraft. Many countries that ban vaping allow heated tobacco products (Japan being the most notable example). Always check your destination's specific rules.

The Bottom Line

Vaping devices must be in carry-on — this is non-negotiable due to lithium battery rules. You cannot vape on the aircraft. E-liquid follows the 100ml carry-on liquid rule, with no restriction in checked baggage. Before any international trip, check whether your destination bans vaping — penalties in countries like Thailand and Singapore are serious. Pack sensibly, bring nicotine alternatives for long flights, and always carry devices in your cabin bag.
