LONDON, United Kingdom: Operations at several airports across Europe faced disruptions Saturday after an apparent cyberattack targeted the service provider for check-in and boarding systems.
Several flights were delayed or cancelled at airports in London, Berlin and Brussels, according to DW news network.
“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.
According to AFP news agency, at least 10 flights were cancelled out of Brussels Airport and another 17 delayed by over an hour after the system was hit by a “cyberattack” overnight on Friday, the airport said.
Manual check-in
Only manual check-in and boarding was taking place at the Brussels air hub, which advised passengers flying on Saturday to check their flight status with airlines before going to the airport.
London’s Heathrow Airport — the busiest in Europe — said its check-in and boarding systems, also provided by Collins Aerospace, were hit by a “technical issue” that “may cause delays for departing passengers”.
A banner on the Berlin Airport website read: “due to a technical issue at a system provider operating across Europe, there are longer waiting times at check-in.”
