Delta says chaos after CrowdStrike outage cost it $380 million in revenue

Delta Air Lines on Thursday said last month’s CrowdStrike outage and subsequent mass flight cancellations cost it some $550 million and reiterated that it is pursuing legal claims against the company as well as Microsoft.

The financial impact includes a $380 million revenue hit in the current quarter “primarily driven by refunding customers for cancelled flights and providing customer compensation in the form of cash and SkyMiles,” the Atlanta-based airline said in a securities filing.

The incident, in which it canceled some 7,000 flights, also meant a $170 million expense “associated with the technology-driven outage and subsequent operational recovery,” the carrier said, adding that its fuel bill will likely be $50 million lower because of the scrubbed flights.
