The power outage at Delta Airlines this week took down computers and stranded thousands of travelers from New York to Tokyo. It was just the latest in a series of computer-related issues that have disrupted other U.S. airlines. Delta said it canceled about 900 flights Monday out of a total of 6,000 worldwide. Nearly 800 were canceled Tuesday and hundreds more were delayed. By Wednesday most flights had resumed, although Delta said it expected about 100 more cancellations. Delta is investigating the outage, which hit the airline’s computer systems early Monday in Atlanta, Georgia. The company said after power was lost, “some critical systems and network equipment” didn’t switch to backup as they were supposed to. In a video message posted online, Delta CEO Ed Bastian apologized to passengers for the shutdown.
