Delays for Delta Air Lines’ customers stretch into second day

Travel delays for Delta Air Lines’ customers spilled into a second day Tuesday as the air carrier canceled more than 300 flights, a day after a power failure prompted it to ground 1,000 flights worldwide. Delta officials said the flights were being grounded, with over 200 more delayed, in an effort to reset operations and get crews and aircraft back to where they need to be. The company faced widespread cancellations and delays after a power failure knocked out its computer system about 2:30 a.m. Monday in Atlanta (11:30 p.m. PDT) Monday evening, many Delta flights were still delayed at Bay Area airports but the airline appeared to be catching up. Delta’s troubles — along with a technical glitch that caused Southwest Airlines to cancel 2,300 flights over four days last month — illustrate the fragility of the air travel industry’s heavy reliance on technology that controls everything from when and where planes are dispatched to consumer websites. Delta CEO Ed Bastian apologized to customers Monday in an online video, saying operations and customer service employees were working to fully restore the system.
