Cyber-attack triggers ongoing disruption at Dublin Airport

Dublin Airport is experiencing a second day of disruption at Terminal 2 following a cyber-related outage affecting Collins Aerospace’s Muse software, which manages shared check-in and boarding systems. The incident, part of wider European disturbances, has forced airlines to implement manual processes, slowing baggage handling, check-in, and boarding.

As of midday Sunday, 13 flights were cancelled, with Aer Lingus among the most affected carriers. IT specialists from the United States are en route to support system recovery, while airlines urge passengers to check in online to mitigate delays.

The event highlights the growing vulnerability of aviation infrastructure to cyber threats. Dependence on centralised software can cause cascading operational issues, affecting schedules, efficiency, and passenger experience. For airports and carriers, it reinforces the critical importance of contingency planning, rapid response protocols, and cybersecurity resilience.

Industry observers warn that such disruptions can damage reputational trust and may prompt regulators and operators to reassess risk management strategies across European airports. The incident also underscores the need for cross-border collaboration in securing shared technology platforms used by multiple carriers.

While recovery efforts continue, the outage serves as a reminder that digital transformation in aviation must go hand-in-hand with robust cybersecurity measures to protect operational continuity and maintain passenger confidence.
