London Heathrow, Brussels, and Berlin airports experienced significant delays and cancellations following a cyberattack on Collins Aerospace's MUSE software, prompting calls for enhanced cybersecurity in the aviation sector.
Several major European airports including London Heathrow, Brussels, and Berlin experienced significant delays and cancellations on September 20, 2025, due to a suspected cyberattack targeting a critical service provider for their check-in and boarding systems. The disruption was linked to Collins Aerospace, a company supplying MUSE software widely used by multiple airlines across several airports globally.
The incident primarily affected the electronic check-in and baggage processing systems, forcing airport staff to revert to slower manual procedures. At Brussels Airport, the impact was particularly severe, resulting in at least 14 flight cancellations and numerous delays. Heathrow and Berlin saw comparatively fewer cancellations but still faced notable delays, with passengers reporting long queues as online check-in became unavailable. Dublin and other European hubs were also affected but to a lesser extent.
According to reports, Collins Aerospace acknowledged encountering a cyber-related disruption but did not disclose further details about the attacker or the specific motives behind the incident. Authorities are investigating the event, with cybersecurity experts suggesting possibilities such as ransomware or sabotage given the sophistication of the attack. The incident highlights growing concerns over the vulnerability of interconnected digital systems within the aviation sector, especially those reliant on third-party service providers for critical operational functions.
Airlines like EasyJet, Delta, and United Airlines activated contingency plans. Still, passengers expressed frustration at limited communication during the delays. Heathrow Airport issued guidance advising travellers to arrive no more than three hours before long-haul flights or two hours ahead of domestic departures and urged them to check flight statuses before travelling to the airport.
This disruption is the latest in a series of cyberattacks globally targeting essential infrastructure, underscoring the heightened risks posed by the aviation industry's increasing dependence on digital platforms. The incident has prompted calls for more robust cybersecurity measures and better resilience planning within the sector to mitigate the effects of potential future attacks.
