New C3 scanners at EU airports were expected to streamline security processes, but the EU has decided to temporarily revert to previous restrictions.

Starting September 1, 2024, the European Union will reinstate the 100-milliliter limit for liquid containers in carry-on luggage, requiring passengers to place liquids in a transparent bag for separate scanning.

ACI Europe criticized this reinstatement as a setback for passengers and a financial penalty for airports that invested in advanced C3 scanner technology.

The reinstated limit may lead to longer wait times for passengers and financial repercussions for airports that invested heavily in C3 scanners, which are eight times more expensive than traditional devices.

Olivier Jankovec, ACI's Director General, noted that airports adopting C3 technology will face operational and financial disadvantages due to the EU's decision.

The EU's decision stems from concerns that C3 scanners do not meet the required safety standards, prompting the need for further verification.

While the EU has labeled the restrictions as temporary, there is no specific timeline for their eventual lifting, leading to calls for a clear plan from ACI Europe.

The return to the old regulations is expected to create considerable operational challenges for airports, necessitating adjustments in security protocols.

C3 scanners utilize 3D imaging technology, allowing passengers to skip separate scanning of laptops and liquids, which was a significant improvement in security efficiency.

The EU's decision to reinstate the liquid limit is based on information indicating that the scanners do not meet the technical standards for which they were approved.

The introduction of C3 scanners was intended to significantly reduce security checkpoint wait times, but the reinstatement of liquid limits undermines this goal.

Passengers will once again need to present liquids in a transparent plastic bag, adhering to the 100-milliliter limit per container.
