Brussels and Berlin airports also affected as ‘technical issue’ hits service provider for check-in and boarding systems

Flights have been delayed and cancelled at airports including Heathrow after an alleged cyber-attack targeted a service provider for check-in and boarding systems.

Airports in Brussels and Berlin are also experiencing delays and disruption after the “technical issue” affecting Collins Aerospace, which works for several airlines at airports across the world.

Heathrow said passengers should check their flight status before travelling. A statement said: “Collins Aerospace, which provides check-in and boarding systems for several airlines across multiple airports globally, is experiencing a technical issue that may cause delays for departing passengers.

“While the provider works to resolve the problem quickly, we advise passengers to check their flight status with their airline before travelling. Please arrive no earlier than three hours before a long-haul flight or two hours before a domestic flight.
