Delta Air Lines faced significant operational challenges on Monday, canceling hundreds of flights as it continues to recover from a global software outage that occurred three days prior. The incident, triggered by a faulty software update implemented by cybersecurity firm CrowdStrike, initially led to the cancellation of more than 3,500 flights over the weekend.
FlightAware reported that Delta canceled approximately 1,300 flights and delayed around 1,600 on Sunday alone. By Monday morning, the airline had canceled 626 flights and delayed 144, accounting for about 20% of its scheduled operations. In contrast, American Airlines reported only 38 cancellations and 155 delays, impacting about 5% of its planned flights.
The software glitch particularly affected Microsoft’s Windows operating systems, leaving many corporate users unable to access their systems and causing major disruptions across various sectors, including healthcare, retail, and financial services. Airlines were severely impacted, with over 46,000 flights delayed and more than 5,000 canceled on Friday.
Delta CEO Ed Bastian expressed regret over the situation, stating that canceling flights is a last resort and that the airline is dedicated to connecting travelers worldwide. Delta has implemented a travel waiver allowing customers to change their flights without charge and has offered meal vouchers, hotel accommodations, and transportation to those affected.
U.S. Secretary of Transportation Pete Buttigieg highlighted the numerous complaints received by his department regarding Delta’s handling of the disruptions. He emphasized the importance of providing affected customers with refunds, free rebooking options, and prompt reimbursements for related expenses, stating that individuals should not be forced to spend the night at airports or endure long wait times to speak with customer service.
