Power outage at Delta causes flight cancellations, delays

Atlanta-based Delta, the second-largest U.S. airline by passenger traffic, said it had canceled 451 flights after a power outage that began around 2:30 a.m. EDT (0630 GMT) in Atlanta. The disruptions dealt a blow to Delta's efforts to use its recent success in avoiding flight cancellations to win over corporate and leisure customers. With Monday's outage, Delta now joins rivals Southwest Airlines Co and American Airlines Group Inc among airlines that have suffered flight disruptions during the past year due to data system malfunctions.
