Can You Take a Vape on a Plane? The UK Rules Explained

Yes, you can take a vape on a plane from the UK, but only in your hand luggage or on your person. Vapes and spare batteries are not allowed in checked baggage. You can't vape or charge your device on board. E-liquid in your hand luggage follows the normal liquids rules, which at most UK airports means bottles of 100ml or less in one clear bag. A standard 10ml bottle is fine.

These rules come from the Civil Aviation Authority and the airlines, not vaping law as such. For the rest of the UK's vaping rules, see our vape laws UK hub.

The rules in one table

Why vapes can't go in the hold

It's about the battery. Vapes run on lithium batteries, and a battery that overheats in a suitcase in the hold is a fire nobody can reach. In the cabin, crew can see and deal with it.

The CAA lists "battery-powered portable electronic smoking devices (e.g. e-cigarettes, e-cigs, e-cigars, e-pipes, personal vaporizers)" as not allowed in checked baggage. Its conditions for carrying them are:

• They must be carried on your person (in practice, in the cabin with you).
• The device and batteries must not be recharged on board.
• You have to take steps to stop the device firing by accident.
• Spare batteries must go in carry-on baggage, each protected by its retail packaging or by insulating the terminals.

The CAA also sets battery size limits of 100Wh for lithium-ion and 2g of lithium for lithium metal batteries. Ordinary pod kits and vape pens are well under that.

Stop it firing in your bag

This is the part people forget. A vape that fires while squashed in a bag can overheat. Before you fly:

• Lock it. Many button-fire devices lock with five quick clicks. Check your manual.
• Take the pod out of auto-draw pod kits if you can, so pressure changes or a squashed bag can't trigger it.
• Carry it in a case or a separate pocket, away from keys and coins.
• Protect spare batteries in a plastic battery case or their original packaging.

British Airways asks for devices to be packaged to prevent accidental activation, and the CAA rules require it too.

E-liquid in hand luggage

E-liquid counts as a liquid at security. According to GOV.UK, at most UK airports:

• containers must hold no more than 100ml
• they go in a single clear, resealable bag that holds no more than a litre and measures about 20cm by 20cm
• you get one bag per person

UK nicotine e-liquid is sold in bottles of 10ml or less, so the bottle size is rarely a problem. Larger shortfill bottles are usually under 100ml too, but check the label.

Some UK airports now let you carry bigger containers through security. GOV.UK says the rules depend on the airport, so check with your departure airport and any airport you connect through, especially for the return leg.

Pressure changes can push liquid out of a pod or tank. Some people empty their pod before flying, or carry it upright in a sealed bag. Our vape leaking guide covers why it happens.

Can you vape on the plane?

No. Airlines ban it. British Airways says smoking, including vapes and e-cigarettes, is prohibited on board its aircraft. Ryanair's terms of carriage allow e-cigarettes to be carried but prohibit using them at any time during the flight. That includes the toilets.

You also can't charge a vape on board, from a seat socket or a power bank. Charge it fully before you leave.

At the airport

Each airport sets its own rules on vaping in the terminal. Look for the signs and any designated smoking area, and don't assume you can vape indoors.

Gate-checked bags

If your wheelie case gets taken at the gate because the overhead bins are full, take your vape and spare batteries out first. BA's guidance says this directly. The same applies on any airline: vapes go in the cabin, whatever happens to the bag.

Flying back to the UK

From 1 October 2026, the UK charges Vaping Products Duty on vaping liquid. The government says travellers arriving in Great Britain can bring up to 50ml of vaping liquid for their own use without paying duty or tax. Anything above that has to be declared, with duty paid on the full amount. Northern Ireland has different allowances. The details are on GOV.UK's bringing goods into the UK page, and our vape tax guide explains the duty itself.

Check your destination too

Vaping laws vary a lot between countries. Some restrict or ban vapes outright. Before you travel, read the local laws section of the FCDO travel advice for your destination.

Quick checklist before you fly

1. Vape and spare batteries in your hand luggage or pockets, never in the hold.
2. Device locked or pod removed, spare batteries in a case.
3. E-liquid bottles in your liquids bag, each 100ml or less unless your airport says otherwise.
4. Fully charged before you leave home.
5. No vaping on the plane, including in the toilet.

These are the UK rules as published by the CAA, GOV.UK and the airlines named. Airlines can set stricter rules, so check your airline's own page before you go. For other rules on buying and using vapes in the UK, see are disposable vapes banned and our guide to the Tobacco and Vapes Act.
