Geneva Airport experienced significant disruptions Tuesday as a technical issue with air traffic control provider Skyguide temporarily halted all flight operations. The incident highlights the increasing reliance on complex software systems within critical infrastructure adn the potential for widespread travel disruption with even brief outages. While flights resumed throughout the day, passengers should anticipate ongoing delays and potential cancellations as the airport works to recover from a substantial backlog, with reduced capacity expected to persist for the next 24 hours.
Geneva Airport experienced significant disruptions Tuesday morning following a technical issue at air traffic control provider Skyguide, halting all departures and arrivals for a period. The incident underscores the vulnerability of air travel to software and system failures.
Flights began to resume shortly after 10:00 a.m. local time, with approximately half of normal traffic restored. By 11:30 a.m., operations had reached 80% capacity, according to Geneva Airport spokesperson Ignace Jeannerat, who confirmed details first reported by lematin.ch.
Throughout the day, delays persisted as the airport worked to clear the backlog. Nine flights were diverted to Basel, Lyon, or their originating cities, and five flights were canceled outright. Passengers were advised to check with their respective airlines for the latest status of their travel plans.
Skyguide temporarily closed Geneva’s airspace as a precautionary measure after the technical problem arose. The company stated that operations would remain at 80% capacity for the next 24 hours.
The disruption stemmed from a software update conducted overnight. While the update was completed, certain system components failed to load correctly, necessitating a return to the previous system and a controlled restart. The airspace over Zurich was not affected by the issue.
“The safety of all flights and passengers was guaranteed,” Skyguide said in a statement.
This is not the first time Skyguide has faced technical difficulties in recent years. In June, the company reduced approach capacity at Geneva by 20% due to similar issues.
