What Happened
The attack struck Collins Aerospace, a subsidiary of RTX, which provides check-in and boarding systems to multiple airlines worldwide. Automated systems were rendered inoperable, forcing airports to switch to manual check-in and baggage drop.
Brussels Airport reported that the disruption began on the night of September 19, causing widespread delays and cancellations. Heathrow confirmed “technical issues” while Berlin Airport warned of longer waiting times.
Impact on Passengers
At least 10 flights were cancelled and dozens more delayed by up to an hour on average. Passengers were urged to reconfirm flight details with airlines before heading to airports.
Delta Air Lines said it had introduced a workaround to minimize disruption.
EasyJet reported normal operations.
Ryanair and British Airways’ owner IAG did not issue immediate statements.
Frankfurt and Zurich airports confirmed they were not affected, while Polish authorities reported no threats to local airports.
Company and Authorities’ Response
RTX acknowledged a “cyber-related disruption” but stressed that the issue was limited to check-in and baggage systems and could be handled manually. “The service provider is actively working on the issue and trying to resolve the problem as quickly as possible,” the company said.
Airport officials cautioned that while flights were still departing, the incident had a significant impact on scheduling. Cybersecurity experts noted that while no group has yet claimed responsibility, the attack highlights growing vulnerabilities in global aviation infrastructure.
