Airport Liquid Rules

Liquid rules at Cologne Bonn

Köln (Cologne), Germany · IATA CGN · ICAO EDDK

Limit lifted

Containers up to 2 L allowed in carry-on

Single central checkpoint (Terminal 1) is fully equipped with CT scanners — no lane selection needed, the new rules apply airport-wide. Containers up to 2L must be leak-proof/spill-proof and can stay in your bag, no plastic bag required; non-spill-proof containers (e.g. takeaway coffee cups) can't be screened by the CT scanner and will be refused.

What this means for packing

·Liquid containers up to 2 L each are allowed in your carry-on.
·Liquids and electronics can stay in your bag at security — no clear plastic bag needed.
·Your return or connecting airport may still enforce 100 ml. Pack for the strictest checkpoint on your route.

Carry a water bottle through security

Bring it empty and refill after security — a clear, single-wall plastic bottle empties fast and clears the checkpoint without the extra screening insulated metal bottles often get.
