Delta Air Lines faced significant disruptions on Monday, canceling hundreds of flights as it struggled to recover from a global software outage that affected operations over the weekend. The airline canceled around 1,300 flights and delayed approximately 1,600 on Sunday alone, following over 3,500 cancellations across Delta and Delta Connection flights from Friday to Saturday.
By 8 a.m. ET on Monday, Delta had canceled 626 flights and delayed 144, which accounted for about 20% of its scheduled operations. In contrast, American Airlines reported only 38 cancellations and 155 delays, representing around 5% of its planned flights.
The troubles stemmed from a flawed software update by cybersecurity firm CrowdStrike late Thursday, which created issues with Microsoft’s Windows operating systems. This left numerous corporate users unable to access their systems, causing widespread disruption, including the notorious “Blue Screen of Death.”
The incident had a ripple effect across various industries, significantly impacting healthcare service providers, delivery companies, retailers, and financial institutions. Airlines, especially Delta, were among the hardest hit, with more than 46,000 flights delayed and over 5,171 canceled on Friday.
Delta CEO Ed Bastian expressed regret over the cancellations, emphasizing that they are always a last resort. He offered apologies to passengers affected by the disruptions, reaffirming Delta’s commitment to connecting the world and acknowledging the difficulties caused by travel interruptions.
Bastian noted that a large number of Delta’s applications rely on Microsoft Windows, including tools related to crew tracking, which were unable to adapt due to the system shutdown. In response to the situation, Delta has implemented a travel waiver allowing customers to change their flights without fee and is providing meal vouchers, hotel accommodations, and transportation.
U.S. Secretary of Transportation Pete Buttigieg reported that his department received numerous complaints regarding Delta’s management of the disruptions. He stated that Delta is obligated to issue refunds, facilitate free rebooking, and provide timely reimbursements for expenses like food and lodging to impacted customers. Buttigieg underscored that no traveler should face having to sleep at an airport or wait excessively for customer service assistance.
