Do Vapes Need to Go in a Liquid Bag

Travelling with a vape can be confusing, especially when it comes to airport security rules. Many passengers are unsure whether their vape or e-liquids need to go in the clear plastic liquid bag at security. The simple answer is that your vape device does not need to go in the liquid bag, but your e-liquids do. Airport security treats e-liquids the same way as other liquids such as toiletries and gels, meaning they must follow the 100ml rule and be placed in a clear resealable bag when passing through security.

Vape Devices and Airport Security

Vape devices, such as pod systems, pens, or box mods, are treated as electronic items rather than liquids. You can keep your vape device in your hand luggage but not in your checked luggage. Lithium-ion batteries, which power most vape devices, are prohibited in the aircraft hold because of fire risk.

At security, you may be asked to remove your vape device from your bag for inspection, just as you would with laptops or other electronic equipment. However, you do not need to place the device in your liquid bag unless it contains a removable tank or pod that is filled with e-liquid.

If your vape has a tank attached, it’s a good idea to empty it before you travel, as changes in cabin pressure can cause it to leak during the flight.

E-Liquids and the 100ml Rule

E-liquids are classed as liquids by airport security, so they must comply with the UK and international 100ml rule. Each e-liquid bottle must be no larger than 100ml, even if it contains less liquid inside. All bottles must fit inside a single clear resealable plastic bag measuring approximately 20cm by 20cm, with a maximum capacity of one litre.

You are allowed one such bag per passenger, and it must be taken out of your hand luggage and placed separately in the tray during security screening. Any e-liquid bottles larger than 100ml will be confiscated, even if they are nearly empty.

To make the process easier, it’s best to transfer any smaller bottles into your liquid bag before arriving at the airport security checkpoint.

Carrying E-Liquids in Checked Luggage

You can pack additional e-liquid bottles in your checked luggage if they are securely sealed and under 100ml each. There is no specific limit to how many bottles you can carry in your hold baggage, but it’s wise to store them in a plastic pouch or toiletry bag to prevent leaks.

Because checked luggage is subject to temperature and pressure changes, bottles should be tightly capped and ideally wrapped in tissue or plastic to avoid spillage.

Where to Pack Vape Coils and Accessories

Vape accessories such as spare coils, drip tips, or empty pods can be packed either in your hand luggage or checked bag. Coils and pods do not count as liquids unless they are pre-filled with e-liquid. For convenience, many travellers pack these accessories alongside their main vape device in their carry-on bag to keep everything together.

Chargers and USB cables should also go in your carry-on luggage, as airlines discourage electronic accessories from being stored in the hold.

Vaping Batteries and Airline Safety Rules

Batteries are one of the most important considerations when flying with a vape. Lithium-ion batteries can only be carried in your hand luggage. You are not allowed to place vape batteries, devices containing batteries, or external power banks in your checked baggage due to fire risk.

If your vape device has removable batteries, it’s best to remove them before boarding and store them safely in a protective case. Avoid carrying loose batteries in your pocket or bag without protection, as contact with metal objects can cause short circuits.

Airlines may also limit the number of spare batteries you can carry, though this is rarely an issue for personal vape use. Always check your airline’s policy before you travel.

Can You Vape at the Airport?

Most UK airports have strict no-vaping policies inside terminals. You cannot vape while inside airport buildings, including in lounges, shops, or waiting areas. However, several airports provide outdoor smoking and vaping areas located before or after security.

Once you pass through security, vaping areas become more limited. Some airports have designated outdoor spaces beyond passport control, but others require passengers to wait until they land at their destination. Always check airport signage and follow local rules.

Can You Vape on the Plane?

You cannot vape on any commercial flight. Vaping is banned by all airlines and treated the same as smoking. Using an e-cigarette in the cabin or aircraft toilet can result in fines, confiscation of your device, or even arrest upon landing.

You also cannot charge your vape device while on board. Most airlines specifically prohibit the charging of e-cigarettes or any battery-powered vaping equipment during the flight.

If you need nicotine during a long journey, consider using nicotine gum or lozenges, which are permitted on flights and provide a suitable alternative.

How to Prepare Your Vape for Flying

Before heading to the airport, detach any tanks or pods from your device and empty them if possible. Cabin pressure changes can cause e-liquid to expand, leading to leaks. Store empty tanks and devices in tissue or small pouches to catch any residual liquid.

Keep your e-liquid bottles in your clear liquid bag for security and pack any extras in your checked luggage. Make sure your vape is turned off before boarding to avoid accidental activation.

If you have a device with a built-in battery, ensure it is fully charged before your trip, as you will not be able to charge it on the plane.

Flying with Vapes Internationally

While UK airports allow vapes in hand luggage, laws vary in other countries. Some destinations, such as Thailand, Qatar, and Singapore, have strict bans on vaping, including possession of devices. Always check local vaping laws before you travel to avoid fines or confiscation at your destination.

When returning to the UK, the same rules apply. You can carry your vape device and e-liquids in your hand luggage, provided all liquids remain under 100ml and stored in the clear plastic bag.

Final Thoughts

Your vape device does not need to go in your liquid bag, but your e-liquids do. Airport security treats e-liquids just like any other liquid, meaning they must be under 100ml and placed in a clear, resealable plastic bag. Vape devices, batteries, and accessories should always be carried in hand luggage and never checked in.

By following these rules and preparing your vape properly before you travel, you can pass through security smoothly and enjoy your journey without any issues.
