A cyberattack targeting Collins Aerospace's MUSE software disrupted check-in and boarding systems at multiple major European airports on Saturday. Flights were delayed and canceled at Heathrow, Berlin, Brussels, and others. Collins Aerospace confirmed the cyber-related disruption, stating that manual check-in could mitigate the impact. While the exact scale of the disruption remains unclear, several airports reported significant delays and cancellations, advising passengers to check with their airlines before traveling. The incident follows a reported hack of St. Petersburg airport's website on Friday.
