Delta Resumes Limited Departures After Outage

Delta Air Lines Inc.’s global operations were thrown into disarray after a computer outage grounded takeoffs worldwide, the second system failure to disrupt a major U.S. carrier in less than a month.

A power outage in the carrier’s home city of Atlanta that began at 2:38 a.m. local time affected computer systems worldwide, including flight status displays, its website and some mobile and airport technology, Delta said. Planes that have already departed are operating normally, the airline, the U.S.’s second-largest, said on its website.

“Delta is advising travelers to check the status of their flights this morning while the issue is being addressed,” it said. The company didn’t estimate how long repairs will take.

Almost 3,300 Delta flights are scheduled for today, including 453 international departures, according to information from aviation database provider OAG. U.S. carriers experienced a series of technical disruptions to flights late last year and early in 2016, including a connectivity flaw at American Airlines that halted flights at its Chicago, Dallas and Miami hubs in September and a reservations-system glitch at Southwest Airlines Co. in October.

Southwest, the biggest U.S. discount carrier, experienced a computer failure in July that prompted cancellations of more than 1,000 flights, though said it didn’t appear to be related to the October incident as it involved an old router and a backup system.
