Delta Air Lines faced significant disruptions on Monday, canceling hundreds of flights as it struggled to recover from a global software outage that had grounded and delayed flights for several days.
On Sunday alone, Delta canceled approximately 1,300 flights and experienced 1,600 delays, as reported by FlightAware. Over the course of Friday and Saturday, the airline had canceled more than 3,500 flights for both Delta and Delta Connection.
By Monday morning, Delta had canceled 626 flights and delayed 144, accounting for nearly 20% of its scheduled operations. In contrast, American Airlines canceled just 38 flights and had 155 delays, representing about 5% of its planned operations.
The turmoil was sparked by a faulty software update from cybersecurity firm CrowdStrike that took place late Thursday. This defect impacted Microsoft’s Windows operating systems, severely disrupting corporate users’ access to their systems, and led to numerous issues, including the infamous “Blue Screen of Death.”
The incident affected nearly every major industry, with airlines and airports among the hardest hit. On Friday alone, over 46,000 flights were delayed, and more than 5,000 were canceled, with Delta bearing the brunt of these disruptions.
Delta CEO Ed Bastian expressed regret in a statement, emphasizing that cancellations are not taken lightly and apologizing to all those affected. He noted that Delta relies heavily on Microsoft Windows for various applications, including crucial tools for crew tracking, which contributed to the delays.
In response to the situation, Delta has implemented a travel waiver allowing customers to change their flights without penalty, as well as providing meal vouchers, hotel accommodations, and transportation.
Transportation Secretary Pete Buttigieg announced on social media that his department has received numerous complaints regarding how Delta handled the situation, stating that the airline must offer refunds, free rebooking, and prompt reimbursements for expenses related to food and lodging for impacted customers. Buttigieg added that no one should have to spend the night at an airport or wait for extended periods to speak with customer service.
