Switzerland’s two busiest gateways—Zurich (ZRH) and Geneva (GVA)—entered the key ski-season weekend facing an unwelcome stress-test. Early on Saturday, December 6, airport-operation dashboards showed 10 outright cancellations and 141 delays, creating a ripple effect across the European network. The disruption coincided with the first major wave of winter holidaymakers heading to the Alps and with a band of low-pressure weather bringing wet snow and cross-winds to the Swiss Plateau.
Air-traffic managers said the imbalance between scheduled capacity and de-icing/stand-allocation resources was the main bottleneck: while runways remained technically open, the longer ground-handling cycle times forced airlines—from SWISS and Lufthansa through to easyJet and KLM—to push back departures. As Zurich funnels around 90 % of Switzerland’s long-haul belly cargo, freight forwarders also faced knock-on delays that could stretch lead times for just-in-time supply chains.

For corporate travel managers the timing is awkward. December traditionally sees a spike in executive shuttles for year-end board meetings and Davos pre-visits. Companies with “dual-hub” policies (flying into Milan or Munich if Swiss hubs snarl up) dusted off their contingency playbooks, while travel risk analysts reminded assignees that EU Regulation 261 compensation may apply for delays over three hours.
Both airports set up pop-up customer-care desks, but passengers reported queue times of up to 90 minutes to rebook. SWISS urged travellers to use its app for real-time updates and reissue e-boarding passes automatically—an early test of the carrier’s new IROPS automation launched last month. The Federal Office of Civil Aviation said it will review de-icing staffing levels and is considering temporary slot-swap flexibility so airlines can recover schedules faster during peak winter weekends.
Looking ahead, meteorologists expect another disturbance mid-week, underscoring the need for employers to build buffer days into project start-dates and to remind mobile workers of remote-work options if travel stalls again.
