Travelers at Dublin Airport continue to face chaos as a cyber-attack on critical airline systems triggered a second straight day of disruption at Terminal 2.
The outage, linked to a Europe-wide technical problem, has left airlines struggling to process passengers. By midday on Sunday, a total of 13 flights had been scrapped—nine incoming and four departing—while several others faced lengthy delays.
Aer Lingus warned passengers to brace for significant disruptions, urging them to check in online before heading to the airport. Despite efforts to keep flights running, the carrier confirmed delays and cancellations would be unavoidable.
Airport officials explained that airlines were relying on manual workarounds to issue boarding passes and bag tags, which has slowed the entire process. Passengers have been told to arrive with plenty of extra time—two hours ahead of short-haul flights and three for long-haul journeys—while closely following updates from their airlines.
The problem has been traced to Collins Aerospace’s Muse software, a system that allows multiple airlines to share check-in desks and boarding gates. The company acknowledged a “cyber-related disruption” but has yet to reveal what triggered the fault or how long it will take to fully resolve.
Adding to the weekend’s turbulence, Terminal 2 was evacuated on Saturday after police were alerted to a suspicious piece of luggage. The Irish Army’s bomb disposal unit assisted Gardaí, but the terminal was later declared safe, allowing operations to resume.
For now, passengers are advised to remain alert to sudden changes, as uncertainty lingers over how quickly normal service can be restored.
