Overview

• Electronic check-in and baggage systems failed at Heathrow, Brussels and Berlin, with Dublin and Cork later reporting minor impact, forcing airlines to switch to manual processing.
• Brussels Airport asked carriers to pre-cancel up to 50% of Sunday departures to manage queues and reduce late cancellations.
• Collins Aerospace and parent RTX confirmed a cyber-related disruption to the MUSE software and said the issue is limited to check-in and baggage drop as teams work on recovery.
• Aviation data firm Cirium reported 29 cancellations across Heathrow, Brussels and Berlin by late morning Saturday, alongside widespread delays from manual procedures.
• The UK National Cyber Security Centre and Germany's BSI engaged with affected operators, the European Commission said air traffic control and safety were unaffected, and no attacker has been identified.
