Delta Air Lines canceled numerous flights on Monday, struggling to recover from a significant global software malfunction that disrupted operations over the weekend. The Atlanta-based airline reported 1,300 flight cancellations and 1,600 delays on Sunday alone, following over 3,500 cancellations of Delta and Delta Connection flights on Friday and Saturday.
As of Monday morning, Delta had canceled 626 flights and delayed 144, which accounted for around 20% of its planned operations. In contrast, American Airlines canceled only 38 flights and delayed 155, approximately 5% of its scheduled flights.
The airline’s troubles are linked to a faulty software update by cybersecurity firm CrowdStrike, which occurred late Thursday night. This issue affected Microsoft’s Windows operating systems, resulting in corporate users losing access to their systems and experiencing frequent system crashes.
The incident impacted various sectors, including healthcare, delivery services, retail, and finance, with airlines and airports experiencing the most severe consequences. On Friday, over 46,000 flights were delayed, and more than 5,000 were canceled, with Delta suffering the most significant setbacks.
Delta CEO Ed Bastian expressed regret on Sunday, stating that canceling flights is a last resort and a decision that is not taken lightly. He apologized to all passengers affected and emphasized the company’s commitment to connecting travelers, acknowledging the frustration caused by the disruption.
Bastian highlighted that many of Delta’s applications rely on Microsoft Windows, including a crucial crew tracking system that could not adapt to the shutdown. To assist affected passengers, Delta has introduced a travel waiver for free flight changes and provided meal vouchers, hotel accommodations, and transportation.
On Sunday, Transportation Secretary Pete Buttigieg noted on social media that his department had received numerous complaints regarding Delta’s response to the disruption. He urged the airline to issue refunds, offer free rebooking, and ensure timely reimbursements for meals and hotel stays for those impacted.
Buttigieg emphasized that no one should have to spend the night stranded at an airport or endure long wait times to speak with customer service.
