Overview

• Collins Aerospace said its check-in and bag-drop software was hit by a cyberattack and that restoration efforts are ongoing.
• The disruption began Friday night and affected multiple hubs that use the supplier, including Brussels, Berlin Brandenburg and London Heathrow.
• Brussels Airport asked airlines to cancel half of Sunday departures and by Sunday morning recorded 38 cancellations and six diversions.
• Berlin Brandenburg disconnected from the affected system and switched to manual processing, warning of longer waits but saying the airport itself was not attacked.
• Heathrow reported supplier-linked registration issues, kept most flights operating and urged passengers to check with airlines or use online check-in.
