Cyber Disruption at Collins Aerospace Forces Manual Check-Ins at Brussels, Heathrow and Berlin

Reliance on the MUSE platform exposed how a single vendor issue can snarl passenger processing across hubs.

Overview

  • Collins Aerospace acknowledged a disruption related to cyberattacks in its MUSE software and said teams are working to restore service as quickly as possible.
  • Affected airports switched to manual check-in and boarding, causing long queues and delays, with Brussels confirming 14 cancellations and urging travelers to verify flights before heading to the airport.
  • Heathrow warned of potential departure delays and advised passengers to arrive early, while Berlin reported paper-based boarding lists as part of contingency operations.
  • Impacts varied by airline, with Delta saying it expected minimal disruption after deploying a workaround and easyJet reporting normal operations.
  • Authorities reported no claim of responsibility and no confirmed attribution, underscoring the systemic risk from widely used third‑party airport systems.
