A cyberattack targeting Collins Aerospace's check-in software disrupted operations at several European airports, including Brussels, Berlin, and London, over the weekend. Brussels Airport was hardest hit, canceling nearly 140 flights scheduled for Monday due to the ongoing system outage. While other airports reported smoother operations on Sunday, manual check-in processes are causing delays and cancellations. The attack's origin remains under investigation, but aviation safety and air traffic control remain unaffected. Passengers are advised to check flight statuses before traveling and utilize alternative check-in methods.
