Delta struggles to recover from cyber outage

Delta Air Lines continued to struggle to restore its operations on Monday, three days after a global cyber outage snarled flights around the world, stranding thousands of customers across the country.

The Atlanta-based airline had cancelled 778 flights, or about 20% of the scheduled total as of 1:30 p.m. EST on Monday, according to data from FlightAware. It accounted for about half of total flight cancellations.
