Brussels [Belgium] September 20 (ANI): Flights at major European airports like Brussels, London Heathrow and Berlin were hit by delays and cancellations on Saturday after a cyberattack targeted a single service provider responsible for check-in and boarding systems. Brussels Airport confirmed that the attack late Friday night had forced automated systems offline, leaving only manual check-in and boarding possible. 'There was a cyberattack on Friday night, 19 September, against the service provider for the check-in and boarding systems affecting several European airports, including Brussels Airport,' the airport said in a statement. London Heathrow Airport said Collins Aerospace, a global company that provides check-in and boarding systems to several airlines, was facing a technical issue linked to the disruption. Berlin Airport also reported longer waiting times at check-in, citing a technical issue at a 'system provider operating across Europe.'
