Ransomware attacks against Collins Aerospace, a company that provides check-in systems at several European airports, have caused continental disruption for the fourth day in a row.
At the time of this writing, London's Heathrow airport has 90% delayed flights, with an average delay of 29 minutes, according to Flightradar24, a website that monitors air traffic. 88% of flights at Brussels Airport were delayed, with an average delay of 43 minutes. 94% of flights at Berlin Brandenburg Airport are delayed, with an average delay of 1 hour. Dublin Airport has an average delay of 26 minutes, with 91% of flights delayed.
“There is currently no timeline until the amendment is implemented,” Graeme McQueen, a spokesman for Dublin Airport, told TechCrunch in a statement. The airline said “we continue to deploy manual workarounds while work continues to fix IT issues that are affecting check-in and boarding systems.”

At this time, it is still unknown when the issue will be resolved.”
A warning on the Berlin airport's official website stated that “waiting is long.”
A spokesperson for airports in Heathrow, Brussels and Berlin did not respond to a request for comment.
