A cyberattack on Collins Aerospace has disrupted check-in and boarding systems at major European airports, with Heathrow, Brussels, and Berlin being the most affected. The attack led to numerous flight delays and cancellations, forcing airport staff to switch to manual operations.
Collins Aerospace, a major aviation and defense company, confirmed a "cyber-related disruption" to its Muse software. The incident started on a Friday night, causing long lines and frustrating delays for thousands of travelers.
RTX, the parent company of Collins Aerospace, downplayed the severity, stating that the impact was limited to electronic check-in and baggage drop and could be handled manually. However, airports like Brussels and Berlin warned that manual check-in would continue to cause delays. Heathrow advised travelers to check their flight status before heading to the airport.
According to data from aviation provider Cirium, 29 flights were canceled across the three airports.
This incident highlights the fragility of critical infrastructure that relies on a single provider. Cybersecurity experts warn that a single point of failure can cause major disruptions across multiple sites. Attacks on the aviation sector have increased by 600% from 2024 to 2025, exposing the risks of a system that prioritizes efficiency but is vulnerable to cyber threats.
Experts are now calling for stronger security measures, better contingency plans, and increased vigilance to protect travelers and operations from similar attacks.
