Carry-On Liquids: What You Need to Know Before Your Next Flight

Ever stood at security wondering why your water bottle got tossed? The answer is simple: most airports stick to a 100ml rule for liquids in carry‑on bags. Knowing the exact limits and a few handy tricks can save you time, money, and a lot of frustration.

What You Can Carry in Your Hand Luggage

In 2025 the worldwide standard still says every liquid, gel, or aerosol must be in a container of 100ml (3.4 oz) or less. All containers go into a single clear, zip‑top bag that holds up to 1 litre. Anything bigger than 100ml, even if it’s half full, stays in checked luggage.

There are a few exceptions that most travelers forget:

• Medication: Prescription liquids, insulin pens, or allergy sprays are allowed in reasonable amounts. Keep the prescription label handy.
• Baby supplies: Formula, breast milk, or juice for infants can exceed 100ml. You’ll need to declare them at the checkpoint.
• Special diet items: If you have a medical diet, you can bring larger portions, but you must show proof.

Vape juice falls under the standard liquid rule. In places like Dubai, you can only pack vape liquid in a 100ml container and keep the device in your hand luggage. Some airlines also require the device to be turned off and the tank emptied.

Smart Packing Tips to Breeze Through Security

Here’s a quick checklist you can follow the night before:

1. Use travel‑size containers: Re‑fill 100ml bottles with your shampoo, conditioner, or lotion. They’re cheap and reusable.
2. Label each bottle: Write the product name on the outside. It speeds up the officer’s check and reduces the chance of a bag being pulled aside.
3. Pack the clear bag first: Place it at the top of your carry‑on so you can just pull it out when asked.
4. Keep electronics separate: Laptops, tablets, and vape devices should be easy to remove.
5. Know the airport rules: Some airports allow a few extra items like sunscreen or wet wipes over 100ml if they’re sealed in a retail package. When in doubt, ask the staff.

If you’re traveling to the UAE, remember that the Emirates security crew can be stricter about liquids that look like alcohol or any suspicious odor. Stick to clear, non‑perfumed products to avoid extra checks.

Running late? Toss any leftover liquid into a resealable bag and hand it to the security officer. They’ll usually let you discard it on the spot without wasting the whole bag.

Finally, always double‑check the airline’s specific policy. Low‑cost carriers sometimes have tighter rules about carry‑on size and weight, which indirectly affects how many liquid containers you can fit.

By following these guidelines, you’ll zip through security without the dreaded “liquids confiscated” moment. Pack smart, stay calm, and enjoy the flight.
