SUMMARY
Airlines are still dealing with the aftermath of Friday's global IT outage, causing widespread cancellations and delays. By 11 a.m. ET Sunday, over 1,000 flights were canceled, and more than 2,300 were delayed, according to FlightAware. Delta Air Lines faced 539 cancellations, while United Airlines had 254. Delta's regional subsidiary, Endeavor Air, also saw significant disruptions. The outage stemmed from a defect in an update for Microsoft Windows hosts, as reported by cybersecurity firm Crowdstrike, which assured that it was not a cyber incident. The Federal Aviation Administration (FAA) issued ground stops early Friday, affecting several major U.S. carriers, including American Airlines, United, and Delta.
