Dublin Airport is facing a second day of disruption to its check-in and baggage drop in Terminal 2 following yesterday’s cyber attack which impacted several airports across Europe.
Airport operator daa said it is continuing to support airlines as they deal with the ongoing disruption.
Aer Lingus has said the incident “has significantly impacted operations, leading to flight delays, and a number of cancellations”.
“We are communicating with impacted customers and are advising passengers to check their SMS and our website for the latest updates,” the company said in a statement.
“We appreciate everyone’s patience and cooperation as we continue to manage this significant disruption,” it added.
A cyber attack at a provider of check-in and boarding systems yesterday disrupted operations at several major European airports including London’s Heathrow, the continent’s busiest, causing flight delays and cancellations.
Daa said check-in and boarding systems were still impacted today, as some airlines continue to use manual workarounds to generate bag tags and boarding passes.
“This means that the check-in and bag drop processes may take slightly longer than normal,” daa said.
It added that passengers should plan to arrive at the airport as normal today, however, those needing to check-in or drop off bags at the airport “should allow additional time”.
Operators have said the airport expects to operate a full schedule today.
Yesterday’s evacuation of the airport following a security alert was unrelated to the cyber attack, daa said.
London, Brussels and Berlin airports also experienced delays and disruption following the “technical issue” affecting Collins Aerospace, which works for several airlines at multiple airports across the world.
The disruption began on Friday night and continued throughout yesterday, with flights cancelled or delayed as the impacted airlines had to carry out check-in and boarding operations manually.
Passengers due to fly from the London Heathrow’s Terminal 4 said they were met with queues, delays and confusion as to whether they’d be able to make their planned trips.
Heathrow said passengers should check their flight status before travelling to the west London airport.
“Work continues to resolve and recover from Friday’s outage of a Collins Aerospace airline system that impacted check-in,” Heathrow said.
“We apologise to those who have faced delays, but by working together with airlines, the vast majority of flights have continued to operate.
“We encourage passengers to check the status of their flight before travelling to Heathrow and to arrive no earlier than three hours for long-haul flights and two hours for short-haul.”
It is understood British Airways at Terminal 5 remains unaffected and has been operating as normal.
Around 14 flights were cancelled and some delayed across the other terminals on Saturday, although it is not clear which of these were caused by the technical issue.
Brussels Airport said : “As a result of a cyberattack on the external service provider of the check-in and boarding systems, check-in operations at several European airports, including Brussels Airport, are heavily disrupted.
“The service provider is actively working on the issue and trying to resolve the problem as quickly as possible.
“This has a large impact on the flight schedule and will, unfortunately, cause delays and cancellations of flights.”
A statement on the Berlin Airport website said there were longer waiting times at check-in.
Collins Aerospace said yesterday it was working to resolve the issue as soon as possible.
It said: “We have become aware of a cyber-related disruption to our Muse (multi-user system environment) software in select airports.
“We are actively working to resolve the issue and restore full functionality to our customers as quickly as possible. The impact is limited to electronic customer check-in and baggage drop and can be mitigated with manual check-in operations.”
The European Commission, which takes part in managing airspace across Europe, said it is monitoring the situation but added there were no signs the cyber attack was “widespread or severe”.
