Air travelers are facing another day of disruption at several European airports including Heathrow, after a cyber-attack knocked out a critical check-in and baggage system.
Hundreds of delays were reported on Saturday as the software used by multiple airlines failed, leading many impacted airports to use pen and paper to board passengers.
Brussels Airport stated that it had no indication yet of when the systems would be restored and requested that airlines cancel half their departing flights.
RTX, which owns the software provider Collins Aerospace, acknowledged a cyber-related disruption at some airports and is working to resolve the issue as soon as possible.
Its Muse software, which allows various airlines to share check-in desks and gates, was identified as the source of the problem.
Passengers are experiencing long queues at check-in areas, with Heathrow apologizing for the delays while emphasizing that most flights are still operating.
Travellers were urged to arrive early and check their flight status due to the ongoing issues. Reports indicate that some passengers have endured over two-hour waits to check in, while others have missed connecting flights.
In Brussels, the manual check-in is expected to continue and additional personnel have been allocated to assist in minimizing further disruption, while Dublin Airport is maintaining a full schedule despite the issues.
Cybersecurity officials are currently collaborating with Collins Aerospace and affected airports to understand the full scope of the situation, while monitoring agencies are keeping an eye on any potential widespread impact.
