Dublin Airport Disruptions Continue After Cyber-Attack

Dublin Airport is confronting a second day of serious operational problems at Terminal 2 after a cyber-attack knocked out essential check-in and baggage systems. By midday on Sunday, 13 flights had already been cancelled, including nine arrivals and four departures. Aer Lingus warned passengers that delays and further cancellations were expected throughout the day. Travelers are being urged to monitor airline updates closely, as these disruptions are creating widespread complications for those trying to maintain their travel schedules.

Airport officials stated that the ongoing problem is connected to a Europe-wide technical issue affecting multiple airlines. To cope, carriers have implemented manual procedures, including:

• Printing boarding passes by hand
• Generating baggage tags manually
• Processing passengers more slowly than normal automated systems allow

Dublin Airport is continuing to assist impacted airlines but has cautioned that major delays are still expected. Travelers are experiencing longer lines, slower service, and heightened stress as airport operations are affected by the ongoing issues. Although online check-in is an option, travelers are still dealing with uncertainty, and flights over the next 24 to 48 hours may experience delays or cancellations, affecting plans.

The disruption originates from Muse, a system developed by Collins Aerospace that enables multiple airlines to share check-in counters and boarding gates. RTX, the parent company, acknowledged the cyber-related problem but has not revealed the cause or provided an estimated timeline for when full functionality will be restored. The uncertainty further complicates travel for passengers, who must depend on slower manual procedures until more information about their flights becomes available.

Compounding the problems, Terminal 2 was temporarily evacuated on Saturday after a suspicious item of airline luggage was reported. Gardaí and the Irish army’s explosive disposal team investigated before declaring the terminal safe. Together with the continuing system issues, these occurrences underscore the extent of the disruption, signaling that passengers must give themselves extra time, be prepared for delays, and stay alert to prevent missed flights.
