A cyber attack on systems supplied by Collins Aerospace is causing significant delays on flights from European airports including London Heathrow (LHR/EGLL).
RTX, which owns Collins Aerospace, said it was aware of the cyber attack and was working to resolve the issue as quickly as possible.
The affected equipment is a system called Muse, which is used for check-in and baggage drop, meaning that in many cases, this is having to be processed manually leading to delays.
This is latest a long series of high profile cyber attacks on major companies other than systems with Jaguar Land Rover and Marks and Spencers being among two that have suffered significant financial loss as a result off the attacks.
A spokesperson for the National Cyber Security Centre said: “We are working with Collins Aerospace and affected UK airports, alongside Department for Transport and law enforcement colleagues, to fully understand the impact of an incident.”
British Airways, whose main base is at London Heathrow, has confirmed it using a back up system to check in passengers and baggage meaning it is operating as normal.
The biggest three airports that are affected are London Heathrow, Berlin Brandenburg and Brussels. According to data from aviation analytics firm Cirium, as of 12:30 BST a total of 16 departures had been cancelled as well as 13 arrivals across these three airports alone with significant delays affecting many other flights.
Airports, including London Heathrow, are still advising passengers to check the status of their flights before travelling to the airport and not to arrive too early.
The recomend time is three hours ahead of departure for long-haul flights and two hours for European and domestic flights.
