A potent winter storm and staffing shortfalls combined to cripple air traffic between Switzerland and Finland on 7 December, causing 373 delays and 13 cancellations on the Zurich–Helsinki corridor, according to data compiled by OAG and published by VisaHQ. Zurich bore the brunt, as one runway was intermittently closed for snow-clearing while Skyguide throttled arrival rates by 15 percent.
Legacy carriers Air France and KLM recorded the highest disruption, but home carrier SWISS was not immune, with some long-haul connections to Bangkok and New York delayed up to eight hours after crews ran out of duty time. In Helsinki, cross-winds and sleet intensified the cascading delays. Industry analysts estimate more than 6,000 passengers—many of them corporate travellers heading to year-end board meetings—were affected.

Business-travel teams scrambled to reroute executives through Munich and Vienna, but tight aircraft rotations left little slack. Freight forwarders also felt the pinch, as Zurich handles about 90 percent of Switzerland’s long-haul belly cargo; automotive and pharma shipments faced knock-on delays of 12-24 hours.
Skyguide has launched an internal review of staffing resilience, while Zurich Airport pledged to accelerate recruitment of seasonal de-icing crews. Travellers can claim EU 261 compensation for delays exceeding three hours, but lawyers caution that ‘extraordinary weather circumstances’ may limit payouts.
