Delta Air Lines Inc on Aug 10 cancelled more than 300 flights and upended thousands of travellers' plans for the third day in a row after a power outage hit its computer systems, though it forecast a return to normal operations later this afternoon.
Delta, the No. 2 US airline by passenger traffic, said systems that allow customer service agents to process check-ins and dispatch aircraft are now functioning normally. Most of Aug 10's delays and cancellations are the result of flight crews being displaced or running up against maximum allowed work hours, it said.
