Water Bottle on a Plane - Empty or Full Through Security?

Can you take water through airport security? Empty bottles, full bottles, liquid limits and airports with newer scanners.

Carry-on baggageWITH RESTRICTIONS
Checked baggageYES

Short answer

At an airport using the standard liquid rule, the safest option is to pass security with an empty bottle and refill it afterwards. Some airports now allow more under local rules.

Carry-on baggage

Liquids, gels, pastes and aerosols in the cabin are limited at most EU airports to containers of 100 ml or less inside one transparent 1-litre bag. Some airports using newer screening equipment apply different local limits.

Checked baggage

Larger containers are usually possible in checked baggage unless the product is subject to separate dangerous-goods restrictions.

Airport security

Security normally looks at the container capacity, not how much product is left inside. At an airport using the standard rule, a 150 ml bottle containing only 50 ml can still be rejected.

Check your departure airport

General rules are not always enough. Liquid limits and screening procedures can differ by airport, so check the airport you are actually flying from.
