Europe Prepares to Lift Liquid Restrictions at Airports

New scanning technology promises quicker security checks and allows larger liquid containers, but changes will roll out gradually.

Game-Changing Technology Gains Approval

The European Civil Aviation Conference (ECAC) has approved a new explosive detection system that scans liquids more accurately. Airports across the EU can now install scanners that allow liquids up to 2 liters in carry-on baggage.

This marks a major shift from the long-standing 100ml limit, which was implemented due to terrorism-related concerns. Traditional X-ray machines couldn’t detect liquid explosives, which led to the strict volume restrictions for passengers. The new Hi-Scan 6040 CTiX scanners, approved in June 2025, use computed tomography to assess luggage contents in greater detail.

What This Means for Travelers

Passengers may soon carry water bottles, cosmetics, or baby formula in containers up to 2 liters in hand luggage. Computers and tablets will no longer need removal during security screening when using C3-level scanner technology.

Travellers must still check local rules, as not all airports will immediately upgrade to this advanced screening system. Some airports in Germany, Italy, Ireland, Sweden, Lithuania, Malta, and the Netherlands already use these modern scanners. For now, passengers should follow the 100ml limit unless the departure airport confirms otherwise on their official site.

Airports Are Not Required to Comply

Although approved, the new scanners are costly and optional, airports are not mandated to implement them. SEA Group in Italy announced Milan Linate and Milan Malpensa airports will accept larger liquids in carry-on bags. This suggests early adoption is limited and dependent on budget, infrastructure, and operational readiness.

Each airport must apply for equipment testing and receive ECAC certification before using the scanners. Expect phased implementation across Europe, with some airports embracing the change faster than others.

Plan Ahead for a Smooth Journey

Before packing large liquid items, travellers should confirm current regulations at both departure and arrival airports. Outbound and inbound rules may differ, airlines and airports vary widely in how quickly they adopt new technologies.

The European Commission confirmed more airports could deploy the system “in the coming days,” pending internal approval. This evolving change highlights the importance of staying informed when flying within or from the EU.

For now, careful planning and research remain the best way to avoid confusion and stay within travel guidelines.
