Delta sues CrowdStrike after widespread software glitch that caused thousands of flight cancellations

Delta Air Lines Inc. sued cybersecurity firm CrowdStrike Holdings Inc. over the chaos caused this summer by a “catastrophic” software update that disabled millions of computers worldwide and grounded much of the airline’s passenger fleet.

The update crippled Delta’s operations for days, forcing thousands of flight cancellations and delays that affected more than a million of its customers, the airline said in the suit.
