Delta Air Lines faced significant operational challenges on Monday, canceling hundreds of flights as it continues to recover from a global software outage that disrupted travel over the weekend. The Atlanta-based carrier canceled approximately 1,300 flights and delayed 1,600 on Sunday alone, following more than 3,500 cancellations from Friday to Saturday.
As of 8 a.m. ET on Monday, Delta had canceled 626 flights and delayed 144, which represents about 20% of its scheduled operations. In contrast, American Airlines only canceled 38 flights and delayed 155, making up about 5% of its planned flights.
The disruptions were traced back to a flawed software update by cybersecurity firm CrowdStrike, which affected Microsoft Windows operating systems and left many corporate users struggling with access issues, including encountering the notorious “Blue Screen of Death.” The incident had a widespread impact across various sectors, particularly in aviation, with over 46,000 flight delays and 5,171 cancellations reported on Friday alone.
Delta CEO Ed Bastian expressed regret over the cancellations, stating that they are a last resort and not taken lightly. He apologized to all affected travelers, emphasizing Delta’s commitment to connecting the world and recognizing the difficulties caused by travel disruptions.
Bastian noted that a significant number of Delta’s applications rely on Microsoft Windows, particularly a crew tracking tool that failed to cope with the system outages. To assist affected customers, Delta has implemented a travel waiver allowing free flight changes, in addition to offering meal vouchers, hotel accommodations, and transportation.
Transportation Secretary Pete Buttigieg later addressed the situation on social media, mentioning that his department had received numerous complaints about Delta’s response to the disruptions. He insisted that the airline must issue refunds, provide free rebooking options, and ensure timely reimbursements for food and hotel expenses for those affected, reiterating that customers should not face prolonged delays at the airport or difficulty in reaching customer service.
