Delta Air Lines canceled hundreds of flights on Monday as it continues to deal with the fallout from a global software outage that disrupted operations worldwide for three days.
The Atlanta-based airline reported 1,300 flight cancellations and 1,600 delays on Sunday alone, as tracked by FlightAware, with over 3,500 Delta and Delta Connection flights canceled between Friday and Saturday.
As of 8 a.m. ET on Monday, Delta had canceled 626 flights and delayed 144, accounting for roughly 20% of its scheduled operations. In contrast, American Airlines had minimal interruptions, canceling only 38 flights and delaying 155, which is about 5% of its planned flights.
The difficulties originated from a flawed software update implemented by cybersecurity firm CrowdStrike late Thursday, which adversely affected Microsoft’s Windows operating systems. This left many corporate users without system access, and some experienced the notorious “Blue Screen of Death.”
The incident caused widespread disruptions across nearly every major industry, notably impacting healthcare, delivery services, retail, and finance. Airlines and airports faced significant challenges, with over 46,000 flights delayed and more than 5,171 canceled on Friday alone, as reported by FlightAware, with Delta being the most affected.
Delta CEO Ed Bastian expressed regret over the disruptions, stating, “Canceling a flight is always a last resort, and something we don’t take lightly. I want to apologize to every one of you who have been impacted by these events. Delta is in the business of connecting the world, and we understand how difficult it can be when your travels are disrupted.”
Bastian noted that a significant portion of Delta’s applications relies on Microsoft Windows, including a crew tracking tool that failed to accommodate changes due to the system shutdown. To assist customers, Delta has implemented a travel waiver allowing free flight changes, along with provisions for meal vouchers, hotel accommodations, and transportation.
Secretary of Transportation Pete Buttigieg announced on social media that his department has received numerous complaints regarding Delta’s management of the situation. He stated that Delta is obligated to provide refunds, free rebooking, and timely reimbursements for meals and hotel accommodations for those affected.
“No one should be stranded at an airport overnight or stuck on hold for hours waiting to talk to a customer service agent,” Buttigieg remarked.
