Cologne Bonn Airport officially opened its fully modernized central security checkpoint on 14 July 2026, becoming the first major German airport to deploy eleven lanes exclusively equipped with Computed Tomography (CT) scanners [1][5]. This €25 million infrastructure upgrade eliminates mandatory unpacking of electronics and qualifying liquids, allowing laptops, tablets, and leak-proof containers up to 2 liters to remain inside carry-on bags during screening [1][3]. The facility raises the liquid allowance from the standard 100ml limit to 2 liters per individual container, removing the requirement for transparent resealable bags, though this rule applies only at Cologne Bonn and not at connecting airports [1][6]. By enabling 3D material density analysis, the CT technology reduces secondary inspections and accelerates passenger flow ahead of the summer holiday season [5][12].
