All Delta Flights Grounded Worldwide After Massive System Outage (Updating)

Today is going to be a bad day to fly. Following a power outage at its Atlanta headquarters early this morning, Delta Airlines has been in the grips of a massive computer system failure worldwide, leading the company to ground all departing flights.

Multiple news reports passengers were left stranded in airports awaiting departures as gate agents gave out water bottles and wrote out boarding passes by hand. NBC News reports some passengers on a red-eye flight from Los Angeles to Las Vegas were even taken off their plane and brought back to their terminal "with no estimate on when they would be able to depart."

"Large-scale cancellations are expected today," airline officials said in a statement. "All flights en route are operating normally. We are aware that flight status systems, including airport screens, are incorrectly showing flights on time. We apologize to customers who are affected by this issue, and our teams are working to resolve the problem as quickly as possible."

The outage has left thousands of passengers worldwide unsure when they'll be leaving their airports.

More information on the system outage can be found here. The airline says flights between August 8 and August 12 can be rescheduled with a change fee waived.

More on this as we get it. Are you affected by this outage today?

Update 8:45 a.m. EST: Delta now says some flights are beginning to take off, but customers should expect large-scale delays and cancellations today.
