Collins Aerospace, a global supplier of aviation software and services, confirmed it was experiencing a “cyber-related disruption” affecting its systems at select airports. The company, part of RTX Corporation (formerly Raytheon Technologies), said the impact was limited to electronic check-in and baggage drop systems and that airlines could continue operating through manual procedures.
London’s Heathrow — Europe’s busiest hub — warned passengers of delays as staff reverted to manual check-in. Brussels Airport said the attack had rendered automated systems inoperable since Friday night, forcing carriers to process passengers manually, a situation it described as having a “large impact” on flight schedules. Berlin Airport also reported significant slowdowns and advised passengers to expect longer waiting times.
“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,” Brussels Airport said in a statement.
Passengers with flights scheduled for Saturday were urged by the affected airports to confirm travel status with their airlines before arriving at terminals.
Despite the disruption, some major hubs reported no impact. Frankfurt Airport, Germany’s busiest, and Zurich Airport confirmed their systems remained unaffected.
Collins Aerospace said in an emailed statement that it was working urgently to restore systems.
“The impact is limited to electronic customer check-in and baggage drop and can be mitigated with manual check-in operations,” the company noted.
The cyberattack underscores the aviation sector’s growing vulnerability to digital disruptions, with experts warning that dependence on interconnected systems makes airlines and airports increasingly attractive targets for cybercriminals.
