For the third consecutive day, over 1,000 flights in the U.S. have been canceled. Airlines are grappling with the aftermath of a global tech failure that has left countless travelers stuck in airports.

Iran PressAmerica: By early Sunday afternoon, over 1,200 flights to, from, or within the United States had been canceled, with an additional 4,000 experiencing delays, as reported by FlightAware.com. Delta Airlines faced the brunt of the disruptions, accounting for more than 600 of those cancellations.

The chaos started early Friday morning, stemming from a software update by the cybersecurity firm CrowdStrike. This triggered numerous "blue screen of death" errors on Windows systems used by key institutions. As a result, flights were grounded, emergency service call centers were disrupted, and essential services across banks, hospitals, and even television networks faced significant outages. For instance, hospitals had to reroute emergency calls, putting extra strain on their systems.

CrowdStrike CEO George Kurtz apologized to customers and said a fix has been deployed, but experts say getting systems back in order will be a lengthy process.

The outage affected an estimated 8.5 million Windows devices, less than 1% of all Windows machines, according to a Saturday blog post from Microsoft. “While the percentage was small, the broad economic and societal impacts reflect the use of CrowdStrike by enterprises that run many critical services,” Microsoft said. 219
