Delta cancels more flights Monday as fallout from CrowdStrike outage persists

Delta Air Lines canceled flights for a third straight day Monday, as it struggles to recover from a global software outage that took down Microsoft systems around the world. The global outage, related to a faulty update from cybersecurity company CrowdStrike, also hindered operations at shipping and logistics companies, retailers and banks.

Delta CEO Ed Bastian said in a public letter Sunday that it paused flying after the outage occurred on Friday, resulting in 3,500 canceled flights through Saturday, and continuing through Sunday. The outage hit on what was the airline's "busiest travel weekend of the summer," according to Bastian.

On Monday, when most other airlines' schedules were mostly restored to normal, another 1,120 Delta flights within, into or out of the U.S. were canceled or delayed, according to flight tracking website FlightAware. United by contrast canceled 17 flights, while another 112 of the carrier's flights were delayed.
