SWISS International Air Lines is examining whether it can seek damages from Swiss air navigation services provider Skyguide following a major IT outage that disrupted Swiss airspace operations in June 2026.

The review comes after a recent ruling by the European Court of Justice (ECJ), which could have implications for compensation claims related to disruptions caused by air traffic control failures. SWISS is assessing whether the ruling applies to the Skyguide incident and whether it is relevant under the bilateral air transport agreement between Switzerland and the European Union.
The outage forced the temporary closure of Swiss airspace, resulting in the cancellation of 14 SWISS flights and affecting around 1,750 passengers, while numerous other flights experienced delays across the airline’s network. The disruption generated additional costs linked to flight rescheduling, passenger assistance and rebooking.
SWISS has not disclosed the potential value of any claim, noting that calculating the financial impact would require significant effort and is not currently being undertaken.
While the airline stressed that Skyguide remains an essential operational partner, it said recent disruptions underline the need to further improve the resilience and reliability of air traffic management systems.
