Aer Lingus cancels Dublin-origin flights, cites IT outage

LONDON The Irish carrier Aer Lingus cancelled all flights from Dublin to European and U.K destinations on Saturday following a major computer network incident that knocked offline its check in and boarding systems as well as website.

It stated that all outgoing flights from Dublin starting at mid-afternoon were cancelled and that a number of Dublin-bound flights to European destinations were also canceled. Flights from Portugal and Spain were delayed, it said.

A spokesperson for Aer Lingus said that connectivity was restored by the impacted provider (which they didn’t name) and that the airline was restoring IT services. The spokesperson stated that the provider had identified the cause of the incident and that they were not treating it as a ransomware/cyberware attack at the moment. They did not elaborate.

All 51 flights were canceled. Aer Lingus stated that transatlantic flights from Shannon Airport were unaffected, but that the transatlantic service from Dublin was affected by security restrictions. This caused delays and reduced passenger numbers.
