Some of Europe’s largest airports struggled to restore normal operations to automatic check-in systems after being hacked a day earlier. It targeted check-in and boarding systems provider Collins Aerospace, owned by RTX, mainly at London’s Heathrow Airport, Berlin Airport, and Brussels Airport.
Because the incident occurred on the weekend, thousands of passengers were left waiting in long queues and faced lots of cancellations and delays. The disruption caused losses in the hundreds of millions of pounds.
According to the Airport and RTX Administrations, the incident, also known as a cyber-related disruption, impacted several airlines’ MUSE software.
Though only briefly highlighted earlier, the scale of the disruption was extensive, with multiple airports working to resolve ongoing problems. Berlin Brandenburg Airport reported continuing problems, but they said progress was being made. Brussels Airport updated on Sunday that flight schedules were temporarily offline, while Heathrow Airport was still working to recover its check-in systems fully.
As reported so far, most of the airports are gradually returning to normal operations, and delays have been decreasing, though challenges remain.
