Collins Aerospace ransomware attack disrupts check-in at European airports
Impact: Check-in outages and delays at London Heathrow, Brussels and Berlin airports
Collins Aerospace's airport check-in system was hit by a cyber-attack, causing check-in outages and delays at London Heathrow, Brussels and Berlin airports in September 2025. The European Union Agency for Cybersecurity (ENISA) confirmed the cause was ransomware, and the company worked to restore its airline software. A suspect was later arrested in the UK, and Brussels Airport and the company moved to replace the check-in system.
