A cyberattack on a service provider for check-in and boarding systems caused significant disruptions at several major European airports on Saturday. The incident primarily affected Brussels Airport, Berlin's Brandenburg Airport, and London's Heathrow Airport, leading to delays and cancellations of flights.

The attack occurred late Friday night, targeting Collins Aerospace, which provides automated check-in and boarding systems. The company reported a "cyber-related disruption" to its MUSE (Multi-User System Environment) software at select airports. This disruption rendered electronic check-in and baggage drop systems inoperable, forcing airports to revert to manual check-in procedures.

Brussels Airport initially reported a large impact on its flight schedules. By mid-morning Saturday, nine flights had been canceled, four were redirected, and 15 faced delays of an hour or more. Ihsane Chioua Lekhli, a spokesperson for Brussels Airport, stated, "It wasn’t immediately clear how long the disruptions might last."

At Berlin's Brandenburg Airport, communications head Axel Schmidt noted that there were no cancellations due to the cyberattack by late morning, but he acknowledged that the situation could change. The airport had disconnected affected systems to mitigate further issues.

Heathrow Airport, the busiest in Europe, reported minimal disruption. A spokesperson confirmed that there were no flight cancellations directly linked to the cyberattack, although they did not disclose how many flights experienced delays.

Airports across Europe advised travelers to check their flight statuses and apologized for any inconvenience caused. Collins Aerospace, a subsidiary of RTX Corp., stated it was working diligently to resolve the issue and restore full functionality. The company emphasized that the impact was limited to electronic customer check-in and baggage drop, which could be managed through manual operations.

Other major airports, including Frankfurt and Zurich, reported no disruptions related to the cyberattack. EasyJet, one of Europe's largest airlines, confirmed it was operating normally and did not expect any impact on its flights for the day. Delta Air Lines also indicated minimal effects on its operations from the incident.

As the situation developed, officials continued to monitor the impact of the cyberattack and its effects on air travel across Europe.
