Four European airports had to resort to manual passenger check-in on Saturday due to a significant cyberattack and are still facing issues, including flight cancellations. According to Reuters,
the problems began after hackers breached the systems of check-in and boarding service provider Collins Aerospace on Friday evening.
Saturday, September 20, was the most challenging day. As of Sunday, the situation at London’s Heathrow and in Berlin improved significantly, but issues with cancellations and delays persisted.
In Brussels, airlines were asked to cancel half of the flights scheduled for Monday, September 22. On Sunday, 50 out of 257 flights were canceled there.
The company stated on Monday morning that it is closely collaborating with all four affected airports and that the system recovery is "in the final stages."
Currently, it is unclear who might be behind the cyberattack.
On the same day that the aforementioned airports faced issues, an evacuation occurred at Dublin airport due to a suspected false bomb threat.
