06:33 AM EDT, 08/09/2024 (MT Newswires) -- Delta Air Lines ( DAL ) said Thursday it would pursue legal claims against CrowdStrike ( CRWD ) and Microsoft ( MSFT ) for the global outage that caused mass flight cancellations, costing the airline at least $500 million.

"An operational disruption of this length and magnitude is unacceptable, and our customers and employees deserve better," Delta Chief Executive Ed Bastian said in a statement on Thursday.

The direct revenue impact of the incident, which caused the Atlanta-based carrier to cancel 7,000 flights over five days, is estimated to be $380 million. The figure comes mostly from refunds and compensations to affected customers, Delta said.

Neither CrowdStrike ( CRWD ) nor Microsoft ( MSFT ) immediately responded to MT Newswires' requests for comment.
