Brussels (Eurotoday) – An IT problem at Skeyes caused flight delays at Brussels and Charleroi Airports on Thursday, Oct 2, 2025. Ryanair reported 139 delayed flights affecting 25,000 passengers. Delays ranged 20 to 30 minutes; no cancellations.
As GVA News reported, an IT problem at Belgian air traffic control company Skeyes is causing minor flight delays at airports on Thursday, Oct 2, 2025. Every night, flight data for the next day is uploaded into the controllers’ support system. On Thursday, Oct 2, 2025, the data upload was incomplete, which made it harder for controllers to manage flights.
Spokesperson Kurt Verwilligen said safety is the top priority. The delays will stay within limits but cannot be avoided. Reloading the missing data would take the support system offline for 2 to 3 hours. This could cause even bigger delays.
Why are 139 Ryanair flights delayed by Skeyes’ IT problem in Belgium?
At Brussels Airport, a large number of flights are facing disruptions. Spokesperson Jeffrey Franssens confirmed that most delays are between 20 and 30 minutes. He also said that no flights have been cancelled.
Simultaneously, the Charleroi Airport displays on its website that many flights have similarly been delayed. Travellers at both airports are being kept apprised of the information while the airlines and their personnel attempt to manage the day’s schedule, while trying to minimise inconvenience.
Ryanair also criticised the IT problems, noting on Thursday, October 2, 2025, that “139 flights” in Belgium were delayed as a result of the Skeyes issues. The delays affected “more than 25,000” passengers, it claimed. Ryanair is Europe’s biggest low-cost carrier and flies principally from Charleroi Airport, but also flies out of Brussels Airport (Zaventem).
Belgium has faced similar air traffic disruptions before. In January 2025, a technical problem at Skeyes forced Belgian airspace to close for just over an hour. Flights had to be rerouted to neighbouring countries while controllers worked to fix the issue. All flights resumed after a system reboot. In 2023, a power failure at the air traffic management centre in Manila caused the temporary grounding of flights.
