European airports face continued disruption after cyberattack on check-in systems

Some of Europe’s busiest airports — including London’s Heathrow, Berlin Brandenburg, and Brussels Airport — are still grappling with flight delays and cancellations after hackers targeted check-in and boarding software provider Collins Aerospace, owned by RTX.

The attack, which began on Friday, disabled Collins’ MUSE software, forcing airports to fall back on manual check-in operations. While Heathrow and Berlin reported easing disruption by Sunday, Brussels Airport said delays and cancellations would continue into Monday.

Brussels Airport asked airlines to cancel half of Monday’s flights to avoid severe queues and last-minute disruptions. On Sunday, 50 of 257 scheduled departures were canceled, following 25 cancellations the previous day.

Collins said it was in the “final stages” of restoring systems with a secure updated version of its software. However, Brussels Airport noted it had not yet received this update.

Passengers without online check-in or carry-on-only travel faced the worst queues. One traveler in Brussels described the experience:

“For me, it was business as usual. For those poor souls who didn’t do online check-in or have bags to check, they may be waiting a bit.”

Cirium data showed disruption levels varied: Heathrow had “low” delays, Berlin “moderate,” and Brussels “significant.”

The cyberattack is part of a wider wave of hacks disrupting European industries. Recent incidents included Jaguar Land Rover’s halted production and Marks & Spencer’s financial losses running into hundreds of millions of pounds. Regulators have launched investigations into the source of the latest breach.

Stellantis reports data breach at third-party provider for North America

Stellantis, the parent company of Chrysler, said on Sunday it had detected unauthorized access at a third-party service provider supporting its North American customer service operations.

The company confirmed that the breach exposed only basic contact information, with no financial or highly sensitive personal data compromised. Stellantis did not specify how many customers were affected.

“Upon discovery, we immediately activated our incident response protocols … and are directly informing affected customers,” Stellantis said, adding that authorities have been notified. The automaker urged customers to remain vigilant against phishing attempts.

The breach is the latest in a growing wave of cyberattacks targeting automakers. Earlier this month, Jaguar Land Rover was forced to shut factories until September 24 after a major cyber incident disrupted retail and production operations.

The rise in attacks reflects the increasing vulnerability of the automotive industry, as digital platforms and connected services become more integral to customer operations and vehicle support systems.

Cyberattack cripples European airports, disruptions to last into Sunday

A cyberattack on check-in and boarding systems provider Collins Aerospace caused major disruptions on Saturday across several European airports, including London’s Heathrow, Brussels, Berlin, and Dublin, with impacts expected to stretch into Sunday.

The incident targeted Collins’ MUSE software, which supports airlines worldwide. Parent company RTX confirmed a “cyber-related disruption” but gave no details on the attackers. Airports reported flight delays, cancellations, and diversions, while manual check-in procedures were deployed to keep passengers moving.

  • At Heathrow, Brussels, and Berlin, 29 flights were cancelled by mid-day out of nearly 1,100 scheduled departures.

  • Brussels Airport ordered airlines to cancel half of Sunday’s flights to avoid chaotic queues and last-minute cancellations.

  • Berlin and Dublin airports reported long wait times, while Frankfurt remained unaffected.

The European Commission said there was no indication of a “widespread or severe attack,” though investigations are ongoing. Experts warned the case underscores the fragility of aviation’s digital ecosystem, vulnerable to ransomware or sabotage.

Passengers expressed frustration over poor communication:

  • “We haven’t been told anything except that there was a technical fault,” one traveller in Berlin said.

  • Another called it “inexplicable” that systems remain so easily disrupted.

Airlines responded unevenly: easyJet said operations were normal, Delta and United reported only minor delays, while Ryanair and British Airways did not immediately comment.

Authorities in Britain and Germany said cyber defence teams are working with airports to manage the fallout. The disruption adds to a year marked by high-profile hacks, including breaches at Jaguar Land Rover and UK retailers, fueling concern about escalating digital threats across industries.
