Summary: A cyber disruption to Collins Aerospace’s MUSE passenger-processing software has forced several major European airports to switch to manual check-in and baggage drop. The incident has triggered long lines, delays, and some cancellations.
Key Points
Cause: Collins Aerospace confirmed a cyber-related disruption hit its MUSE system, which handles check-in, boarding passes, and baggage tags. Timing: The outage began late Friday, Sept. 19, and carried into Saturday, Sept. 20. Airports most affected: Brussels: Heaviest delays, with cancellations and long waits. London Heathrow: Flight delays, but fewer cancellations; extra staff deployed. Berlin Brandenburg: Long queues as systems were cut off and switched to manual. Dublin & Cork: Only minor disruptions reported. Other airports: Paris and Frankfurt reported normal operations. Airlines: Impact varies by carrier—some reporting minimal disruption due to backup systems. Investigation: The responsible actor is still unknown; authorities are investigating.
What Travelers Should Do
Check flight status before heading to the airport. Arrive on the normal schedule—not earlier than recommended—so terminals don’t overcrowd. Bring booking details and ID ready; boarding passes may need to be re-issued manually. Expect longer lines and possible delays of an hour or more at affected airports.
What’s Next
Collins Aerospace and airport IT teams are working to restore the system, though no timeline has been given. Cybersecurity agencies in multiple countries are involved in the investigation.
