Brussels Halves Monday Departures as Collins Aerospace Cyber Disruption Enters Day Three

Overview

• Collins Aerospace, part of RTX, confirmed a cyber disruption in its MUSE passenger-processing software that disabled automated check-in and baggage tagging at selected airports.
• Manual procedures produced long queues, delays and cancellations at hubs including Heathrow, Berlin and Dublin, while Frankfurt, Zurich and Paris-area airports reported normal operations.
• Brussels Airport reported the heaviest impact over the weekend, canceling about 20% of Sunday departures with 30–90 minute delays and asking airlines to cancel roughly half of Monday takeoffs, affecting about 140 of 276 scheduled departures.
• Brussels officials said the vendor had not yet supplied a secured software version required to restore full functionality, so teams continued using backup systems and laptops.
• EU institutions and Eurocontrol reported no indication of a widespread attack across Europe, and investigations into the incident’s origin are ongoing as airports and the vendor work to restore services.
