Major European airports including Brussels, Berlin and London's Heathrow were hit by "cyber-related disruption" on Saturday, September 20, affecting check-in and baggage drop systems and causing delays, airport service provider Collins Aerospace told Agence France-Presse (AFP).

"We have become aware of a cyber-related disruption to our MUSE software in select airports," the aerospace firm said, after at least three busy European air hubs reported facing disruption and warned of flight delays and cancellations. "The impact is limited to electronic customer check-in and baggage drop and can be mitigated with manual check-in operations," Collins Aerospace added.
