Swiss (LX, Zurich) is assessing whether to seek damages from Swiss air navigation service provider Skyguide following an IT failure that disrupted flight operations on June 21, 2026, based on a recent ruling by the European Court of Justice.
First reported by Neue Zürcher Zeitung, a spokesperson for the airline confirmed to Swiss news agency AWP Finanznachrichten that the carrier was analysing whether the ruling applies to the incident and whether it is enforceable under the Switzerland-European Union bilateral air transport agreement.
The outage led to the closure of Swiss airspace, forcing the cancellation of 14 flights and affecting about 1,750 passengers, causing widespread delays across the carrier’s network. While Swiss has not estimated the potential value of any claim, it said the disruption resulted in additional costs for passenger rebooking, assistance, and operational recovery.
In a statement, Skyguide said the disruption was caused by a technical fault affecting radar displays at its Dübendorf control centre and Zurich tower after restricted airspace for a peace conference was added at short notice. As a precaution, it briefly activated a “Clear the Sky” procedure, although aircraft already approaching Zurich and flights carrying conference delegations were allowed to land.
Engineers quickly fixed the problem and flight operations gradually returned to normal. Skyguide temporarily reduced overflight capacity as a precaution but said Zurich Airport was not directly affected, although some flight disruptions continued for a short time.
ch-aviation has contacted both parties for comment.
“We acknowledge that Swiss is examining this matter. Skyguide does not comment on hypothetical or potential legal action,” a spokesperson for the Swiss air navigation company told ch-aviation.
