Travelling with a vape can be confusing, especially with different airline policies and security regulations worldwide. If you’ve ever wondered, can you take vape juice on a plane, the short answer is yes—but you need to follow specific guidelines. Whether it’s regular e-liquid or CBD vape juice, understanding the rules ensures a smooth journey through airport security.

Let’s go through everything you need to know about taking vape juice on a flight, including carry-on rules, checked luggage restrictions, international travel considerations, and what happens if your vape juice contains CBD.

Understanding Airline Rules for Vape Juice

Most airlines and aviation authorities allow passengers to carry vape juice in both carry-on and checked luggage, but there are restrictions. The 3-1-1 rule applies to all liquids in carry-on bags, meaning:

• Each container must be 3.4 ounces (100ml) or less
• All containers must fit in one quart-sized resealable plastic bag
• Each passenger is allowed one liquid bag

If you’re carrying more than 100ml of vape juice, it must be placed in your checked luggage. However, be cautious—checked luggage is subject to temperature and pressure changes, which might cause bottles to leak or burst. Sealing them in plastic bags can help prevent spills.

Can You Take CBD Vape Juice on a Plane?

If your vape juice contains CBD (cannabidiol), additional rules may apply. In the UK, CBD e-liquids are legal as long as they contain less than 0.2% THC. However, international laws vary. Some countries—such as the United Arab Emirates, Singapore, and Thailand—ban all forms of CBD, even if they are THC-free.

Before travelling with CBD vape juice, check the laws of your destination. While you can often carry CBD e-liquids on domestic UK flights, travelling internationally with CBD can lead to confiscation or legal trouble if the country has strict cannabis laws.

Packing Vape Juice in Your Carry-On vs. Checked Luggage

Bringing Vape Juice in Carry-On Bags

Many travellers prefer keeping vape juice in carry-on luggage to prevent leaks due to pressure changes in checked bags. When packing vape juice in your hand luggage:

✔ Follow the 3-1-1 liquid rule (100ml bottles max, stored in a resealable plastic bag)
✔ Keep it easily accessible for security screening
✔ Ensure the bottle is tightly sealed to prevent leaks

For CBD vape juice, be ready to show product labels or lab reports proving THC content is below 0.2% if requested by security.

Bringing Vape Juice in Checked Luggage

Larger bottles of vape juice must be stored in checked baggage, but be aware of potential leakage risks. To prevent spills:

• Wrap bottles in plastic bags for extra protection
• Avoid overfilling bottles, as pressure changes can cause expansion
• Use padded cases to prevent bottle breakage

Can You Bring Vape Devices and Batteries on a Plane?

While vape juice can go in either carry-on or checked luggage, vape devices and batteries are only allowed in carry-on bags. This rule applies to:

• Vape pens
• Mods
• Pod systems
• Disposable vapes

Lithium-ion batteries cannot go in checked baggage due to fire risks. Ensure your vape device is:

✔ Turned off completely before boarding
✔ Stored in a protective case or carry pouch
✔ Not charging during the flight (charging on board is prohibited)

If you’re travelling with a CBD vape pen, the same rules apply—carry it in your hand luggage and avoid using it while on the plane.

International Travel Considerations for Vape Juice

If you’re travelling internationally, vape regulations vary by country. Some nations ban vapes entirely, while others only restrict certain nicotine strengths or CBD e-liquids.

Countries with strict vaping regulations include:

🚫 Thailand – Vaping is illegal; devices and e-liquids can be confiscated
🚫 Singapore – Complete ban on vaping products
🚫 India – Vaping is illegal in many states
🚫 Australia – Prescription required for nicotine e-liquids

If your vape juice contains CBD, research destination-specific CBD laws before flying. Some countries classify CBD as a controlled substance, even if it’s THC-free.

Tips for Travelling with Vape Juice and Vapes

To avoid issues at security, follow these travel tips:

✔ Check airline policies before flying—each airline may have slightly different rules
✔ Label CBD vape juice properly (if applicable) to prove it contains legal THC levels
✔ Do not use your vape on the plane—this is strictly prohibited
✔ Carry spare coils and pods in your hand luggage, as these are usually allowed

If in doubt, contact your airline or check local regulations before travelling with vape juice or CBD e-liquids.

Can You Take Vape Juice on a Plane? A Quick Summary

Final Thoughts

So, can you take vape juice on a plane? Yes! As long as you follow TSA and airline rules, you can bring both regular and CBD vape juice on flights. Always adhere to the 3-1-1 rule for liquids, store your vape properly, and check local laws if you’re travelling internationally.

Frequently Asked Questions?

How do you pack vape juice on a plane?

When packing vape juice for a flight, ensure each bottle follows the TSA 3-1-1 liquid rule—containers must be 100ml (3.4 oz) or smaller and placed inside a clear, resealable plastic bag if carried in hand luggage. To prevent leaks, leave some space in the bottle for expansion due to cabin pressure changes, keep bottles upright, and store them in a separate pouch or plastic bag. If packing larger quantities, place them in checked baggage, sealed in a plastic bag to prevent spills.

Can I put vape juice in my carry-on?

Yes, you can carry vape juice in your carry-on bag, but it must adhere to liquid restrictions. Each bottle must be 100ml or less, and all liquid containers must fit within a one-quart plastic bag. This makes it easy for security personnel to inspect your liquids during screening. If you’re carrying CBD vape juice, ensure it’s properly labelled and legal at both your departure and arrival destinations.

Do airports check vape juice?

Yes, airports screen all liquids, including vape juice, through X-ray machines at security checkpoints. If your vape juice is within the allowed size limit, security won’t confiscate it. However, if you’re carrying CBD vape juice, security officers might ask for additional documentation, such as proof of THC content (below 0.2% in the UK). Always declare your liquids if asked to avoid unnecessary delays.

Can you take vape liquid in hand luggage in the UK?

Yes, vape liquid is allowed in hand luggage in the UK, but it must comply with the 100ml liquid restriction rule. This means all bottles must be stored in a transparent, resealable plastic bag and easily accessible for security checks. If travelling with CBD vape juice, ensure it contains less than 0.2% THC, as anything higher could be confiscated upon arrival.

Where do I pack my vape liquid?

If you need easy access to your vape juice, pack it in your carry-on bag following the 3-1-1 rule for liquids. If you are carrying larger bottles, store them in checked luggage, properly sealed in plastic bags to prevent leaks. Since vaping is not allowed on flights, it’s best to keep only a small amount in your hand luggage and the rest in your checked baggage.

Where should I put my vape when going through airport security?

Your vape device should be stored in your carry-on bag or pocket, as electronic cigarettes and vape pens are not allowed in checked luggage due to battery fire risks. When going through airport security, remove the vape from your bag if requested, just like other electronic devices, but you generally do not need to take it out unless asked.

What happens if you accidentally leave a vape in checked luggage?

If you accidentally pack a vape device in checked luggage, your bag may be flagged for inspection, and security might remove the vape before your flight. Since lithium-ion batteries pose a fire risk, airlines prohibit them in the hold. If the device is found, it could be confiscated, and in some cases, you might be called to remove it from your luggage before departure.

Is juice allowed in checked baggage?

Yes, vape juice is allowed in checked baggage, and there are no strict quantity limits for non-nicotine e-liquids. However, due to temperature and pressure changes, bottles may leak, so it’s best to store them in sealed plastic bags or leak-proof containers. If carrying CBD vape juice, ensure it complies with both departure and destination laws, as some countries ban CBD products entirely.

How do you take vape liquid abroad?

When travelling abroad with vape liquid, research the local laws on vaping and nicotine e-liquids in your destination. Some countries ban vaping altogether, while others limit nicotine strength or CBD content. Keep all vape juice bottles under 100ml in hand luggage, and pack any extras in checked baggage. If carrying CBD vape juice, ensure you have proper labelling to prove it complies with local THC limits.

Can they tell if you vape on a plane?

Yes, airlines have highly sensitive smoke detectors in airplane bathrooms, which can detect vapour. Many aircraft also have air quality monitoring systems, making it easy for flight attendants to notice if someone is vaping. If caught, you could face fines, legal action, or even a flight diversion. It’s best to wait until you land to avoid severe penalties.
