Dublin Airport’s Terminal 2, the bustling gateway for transatlantic and European flights, is mired in a second day of turmoil on Sunday, September 21, 2025, as a cyber attack cripples check-in and baggage systems across Europe. The outage, unrelated to yesterday’s dramatic evacuation over suspicious luggage, has led to widespread delays, manual processing headaches, and at least 13 flight cancellations—nine inbound and four outbound.
The cyber incident, which struck multiple airports including Brussels, knocked out automated boarding and bag-drop functions starting Saturday. Aer Lingus, a major operator from T2, warned of “significant impacts,” scrapping over a dozen flights and urging passengers to check status updates. Frustrated travelers queued for hours, resorting to handwritten boarding passes amid the digital blackout, while airport staff scrambled with manual workarounds.
Saturday’s security scare added insult to injury: Terminal 2 was evacuated around 11:30 a.m. after Gardaà responded to “an item of airline luggage of concern.” Army bomb experts cleared the bag as safe, allowing operations to resume by afternoon, but not before snarling peak-weekend traffic.
Dublin Airport Authority (DAA) offered support for airlines, but social media buzzed with complaints of confusion and missed connections. As investigations into the cyber breach unfold, passengers are advised to arrive three hours early. This double whammy highlights vulnerabilities in Europe’s aviation network, turning a routine travel day into a logistical nightmare.
