Air travellers are facing another day of disruption at several European airports including Heathrow, after a cyber-attack knocked out a check-in and baggage system.
There were hundreds of delays on Saturday after the software used by several airlines failed, with affected airports boarding passengers using pen and paper.
Brussels Airport said it had no indication yet when the system would be functional again and had asked airlines to cancel half their departing flights.
RTX, which owns software provider Collins Aerospace, said it was aware of a cyber-related disruption to its system in select airports and that it hoped to resolve the issue as quickly as possible. It identified its Muse software - which allows different airlines to use the same check-in desks and boarding gates at an airport, rather than requiring their own - as the system that had been affected.
Heathrow stated efforts to resolve the issue were ongoing, apologising for the delays while noting that the vast majority of flights have continued to operate. Passengers are urged to check their flight status before heading to the airport.
As of Sunday, manual check-in procedures were still in place at airports affected by the cyber-attack, with passenger numbers expected to create long queues and additional delays. Dublin Airport reported its operations were expected to run normally despite the ongoing technical issues.
A National Cyber Security Centre spokesperson mentioned that they were collaborating with Collins Aerospace and relevant authorities to understand the situation, while the European Commission is monitoring the incident closely without indications of widespread damage.
This incident highlights the vulnerabilities within the aviation industry's reliance on digital infrastructure, echoing previous disruptions from cyber incidents.
