Overview

• A cyber‑related disruption in Collins Aerospace’s MUSE platform limited electronic check‑in and baggage drop, prompting manual procedures at affected airports.
• Brussels warned of a difficult Sunday for operations, Berlin-Brandenburg enabled alternative digital check‑in, and Heathrow reported the vast majority of flights operating.
• Saturday saw widespread delays and cancellations, with Brussels reporting double‑digit cancellations as staff processed passengers and bags by hand.
• Eurocontrol said air‑traffic control was unaffected, and several major hubs including Paris Charles de Gaulle/Orly/Le Bourget, Frankfurt and Zurich reported normal operations.
• No group has claimed responsibility and attribution remains unknown, underscoring the supply‑chain risk from shared third‑party systems used across multiple airports.
