Passengers wait in a terminal at Berlin’s Brandenburg airport, in Sch枚nefeld, Germany, Saturday Sept. 20, 2025, after a cyberattack targeting check-in and boarding systems disrupted air traffic at several major European airports.聽
BRUSSELS (AP) 鈥 Fallout from a cyberattack that affected check-in systems at several European airports extended into a second full day on Sunday, as passengers faced dozens of cancelled and delayed flights and airport teams scrambled to limit the damage to travel plans.
Starting late Friday, major airports in Brussels, London and Berlin were hit by disruptions to electronic systems that snarled up check-in and sent airline staffers trying options like hand-writing boarding passes or using backup laptops. Many other European airports were unaffected.
The cyberattack affected software of Collins Aerospace, whose systems help passengers check in, print boarding passes and bag tags, and dispatch their luggage. The U.S.-based company on Saturday cited a 鈥渃yber-related disruption鈥 to its software at “select鈥 airports in Europe.

It was not immediately clear who might be behind the cyberattack, but experts said it could turn out to be hackers, criminal organizations, or state actors.
The European Commission 鈥 the executive branch of the 27-nation European Union 鈥 said that aviation safety and air traffic control were unaffected. There was currently no indication of a widespread or severe attack, while the origin of the incident remained under investigation, it added.
While departure boards for London’s Heathrow and Berlin’s Brandenburg airports were showing signs of smoother arrivals and departures on Sunday, Brussels Airport was still facing considerable issues.
Ihsane Chioua Lekhli, a spokesperson for Brussels Airport, said 45 outbound and 30 inbound flights were cancelled on Sunday, more than double the number a day earlier: 25 departures and 13 arrivals cancelled.
The cyberattack affected only computer systems at check-in desks, not self-service kiosks, she said, and teams were turning to alternative backup systems and pulling out laptop computers to help cope with the impact.
It remained unclear when the situation would be fixed, she said: 鈥淔or now, we have no idea on the timing, we’re taking it day by day.鈥

The airports advised passengers to check the status of their flights before traveling to the airports, and using alternative check-in methods.
鈥淲ork continues to resolve and recover from Friday鈥檚 outage of a Collins Aerospace airline system that impacted check-in,鈥 a Heathrow statement said. 鈥淲e apologize to those who have faced delays, but by working together with airlines, the vast majority of flights have continued to operate.鈥
A rolling message Sunday on the Brandenburg Airport’s web page said: 鈥淒ue to a systems outage at a service provider, there are longer waiting times. Please use online check-in, self-service check-in and the fast bag drop service.鈥
Collins, an aviation and defense technology company that is a subsidiary of RTX Corp., formerly Raytheon Technologies, said Saturday it was working to resolve the issue.
鈥淭he impact is limited to electronic customer check-in and baggage drop and can be mitigated with manual check-in operations,鈥 it said in a statement.
