Departing passengers are being affected at multiple European airports after a cyberattack on Collins Aerospace, which provides boarding and check-in systems. The parent company of Collins, RTX, released a statement that said a "cyber-related disruption" had occurred to its MUSE (Multi-User System Environment) software at some airports but manual check-in operations could be used as a backup.

Among the airports that have been affected are London’s Heathrow Airport, Berlin’s Brandenburg Airport, and Brussels Airport. 

“There was a cyberattack on Friday night 19 September against the service provider for the check-in and boarding systems affecting several European airports including Brussels Airport,” the airport authority said in a statement on its website. “This has a large impact on the flight schedule and will unfortunately cause delays and cancellations of flights ... the service provider is actively working on the issue and trying to resolve the problem as quickly as possible.”

“We are actively working to resolve the issue and restore full functionality to our customers as quickly as possible,” said RTX. “The impact is limited to electronic customer check-in and baggage drop and can be mitigated with manual check-in operations.”

Other major hubs across Europe, including airports in Paris, Frankfurt, and Amsterdam, have reported no impact from the cyberattack thus far.
