Overview

• Brussels Airport asked airlines to cancel about half of Sunday departures and nearly half of Monday’s, with reports citing roughly 50 flights cut on Sunday and about 140 requested cancellations for Monday.
• Collins Aerospace, part of RTX, reported a cyber-related disruption to its MUSE software and said teams are working to restore service at affected sites.
• Automated check-in and bag-drop remain offline at several hubs including Heathrow, Brussels and Berlin, with manual procedures mitigating but not preventing delays; Dublin and Cork reported minor impacts, while Frankfurt and Zurich reported none.
• European and national authorities, including the European Commission, EUROCONTROL, ENISA, the UK NCSC and Germany’s BSI, are monitoring the incident, and aviation safety and air traffic control were reported as unaffected.
• No perpetrator has been identified, and airports continue advising passengers to verify flight status before traveling as queues and missed connections persist.
