Zurich Airport’s full CT-scanner rollout cuts security wait times by 30 %

Three months after replacing conventional X-ray lines with Computed Tomography (CT) scanners, Zurich Airport reports a 30 % increase in passenger throughput and a marked drop in tray handling errors, according to figures released on 28 September. The upgrade, completed ahead of the winter schedule, allows travellers to keep laptops, liquids and electronics inside their cabin bags, reducing divest time and freeing security staff to focus on secondary inspections. CT scanners create a three-dimensional image of cabin baggage similar to a medical CT, enabling software to detect explosives with far higher accuracy. Airport spokesperson Jasmin Bodmer-Breu told public broadcaster SRF that the new lanes can each process up to 250 passengers per hour, versus around 180 previously, making Zurich one of a handful of European hubs that now scan 100 % of hand luggage in 3-D. The project, started in late 2025, cost an estimated CHF 60 million but is expected to pay back within five years through lower staffing ratios and shorter queues that boost non-aeronautical revenue. Business travellers stand to gain the most. Morning peak security times have fallen from 18 to roughly 12 minutes, according to airport app data, improving the reliability of tight connections on Swiss and Star Alliance banks. Travel-management companies (TMCs) say corporate policy may now shift back to recommending Zurich as a hub for intra-European trips, after some clients had diverted via Munich or Vienna during last year’s construction phase. The airport warns, however, that certain dense objects – notably double-walled thermos flasks and stacks of playing cards – still trigger manual inspection. Passengers are advised to place such items separately to avoid hold-ups. Zurich has also rolled out a flight-specific “time-to-gate” calculator on its website so travellers can adjust arrival times based on live queue data. Strategically, the CT installation dovetails with the EU Entry/Exit System, which has been live since April 2026. Faster security frees up floor space for the extra kiosks needed to capture biometric data from third-country nationals, keeping overall dwell time within the airport’s 45-minute Schengen-transfer target. Other Swiss airports, Basel and Geneva, are expected to complete similar CT upgrades by mid-2027.
