Flights grounded, passengers to see delays amid global IT outage

Several airlines halted flights on Friday, while others warned of delays and service disruptions as an unprecedented IT outage impacted global operations.

Early on Friday, cybersecurity giant CrowdStrike experienced a major disruption linked to a tech update. Organizations including Microsoft were left scrambling to restore apps and services used by a huge number of firms.

Flight update and check-in monitors at airports around the world displayed the so-called blue screen of death, indicating a Microsoft system error. Images shared to social media showed a whiteboard displaying flight updates at Belfast International Airport in Northern Ireland, and a handwritten boarding pass for a flight with India’s IndiGo.

“It seems that for the first time we are facing a real global blackout. … The disruption affected not only individual users, but especially large institutions such as banks (including central banks), stock exchanges, airports, paralysing operations during the peak holiday season and causing chaos in many other sectors,” Grzegorz Drozdz, market analyst at Conotoxia, said in emailed comments.

Over 38,000 flights had been delayed globally as of about 5 p.m. ET Friday, with roughly 9,200 of those delays within, into or out of the United States, according to FlightAware data. More than 4,200 flights had been canceled, with roughly 2,650 of them U.S. flights.

U.S. Secretary of Transportation Pete Buttigieg said Friday on CNBC’s “Squawk on the Street” that he expects the transportation delays to be smoothed out and “resembling normal” by Saturday.

“The issue has been identified. It’s really a matter of the kind of ripple or cascade effects as they get everything in their networks back to normal,” Buttigieg said. “These flights, they run so tightly, so back-to-back that even after a root cause is addressed, you can still be feeling those impacts throughout the day.”

Airlines across Europe, the Middle East, the Americas and Asia issued updates outlining the suspected extent of the impact on their flight schedules and wider services, with passengers advised to check their flight status.

The U.S. Federal Aviation Administration said at 10:22 a.m. ET: “The FAA continues to work closely with airlines as they work to resume normal operations. Ground stops and delays will be intermittent at various airports as the airlines work through residual technology issues.”

American Airlines said that as of 5 a.m. ET it had been able to “safely reestablish our operation.” The carrier also said, “We expect there will be impact to our flight schedule today, including delays and cancellations.”
