Travellers wait at Brussels airport after the cyberattack on 20 September 2025.

A cyberattack targeting a provider of check-in and boarding systems has disrupted operations at several major European airports, including London Heathrow—Europe’s busiest—causing flight delays and cancellations on Saturday, 20 September 2025.

Collins Aerospace, which supplies systems to multiple airlines worldwide, reported a technical issue affecting departing passengers. Heathrow Airport warned travellers of potential delays, while Brussels and Berlin airports confirmed similar disruptions.

RTX, the parent company of Collins Aerospace, acknowledged a “cyber-related disruption” affecting its software at selected airports, though it did not specify which ones. The impact is confined to electronic customer check-in and baggage drop, with manual check-in operations remaining available.

Brussels Airport noted on its website that automated systems were inoperable following the incident on Friday night, necessitating manual check-in and boarding. “This has a large impact on the flight schedule and will unfortunately cause delays and cancellations… The service provider is actively working on the issue,” the statement read.

Passengers were advised to confirm their flights with airlines before travelling to the affected airports. Frankfurt and Zurich airports were reportedly unaffected, and EasyJet stated its operations were running normally. Other major carriers, including Ryanair and British Airways, had yet to comment. Polish airports also reported no disruption, according to Deputy Prime Minister Krzysztof Gawkowski.
