Some European airports are starting to phase out the long‑standing 100‑milliliter limit on liquids in carry‑on luggage. The change follows the European Civil Aviation Conference’s (ECAC) approval of new computed‑tomography (CT) scanners that can detect liquid explosives in larger containers.
Airports equipped with the new technology may soon allow passengers to carry liquids of up to two litres in their hand luggage without needing to split them into 100‑milliliter bottles.
ECAC has already approved the CT-based technology and several major EU airports (e.g. Rome, Milan, Berlin, Amsterdam, Dublin) are now rolling it out, but there is no publicly confirmed evidence that any airports in Sweden, Norway, Finland or Iceland have officially scrapped the 100 ml limit yet. In Denmark, only 1 airport – Billund – has informed that they have installed the new scanner and are ready to abolish the 100 ml rule – and btw. also the rule that you have to remove your laptop from your handbag.
However, there is a slight hickup in the rollout.
On 31 July 2025, ACI Europe (Airports Council International) and EU Aviation Security Regulation announced that all airports with the new CT scanners are required to reinstate for now the previous 100 ml restriction at all EU and EEA airports. The request includes those airport that had deployed CT scanners. The reasons are technical concerns and the uneven rollout accross the EU. That means even airports that already had started to relax the limit must now enforce it until further notice
The 100‑milliliter restriction was introduced across the EU in 2006 after a plot to detonate liquid explosives on aircraft was foiled.
