Tens of thousands of Delta passengers around the world were stranded Monday after a power outage at its Atlanta headquarters caused a global computer failure that halted all flights. Flights already in the air are operating normally, the carrier said.
Check-in systems, airport screens and even the airline's website and smartphone apps were affected by the meltdown, which began at 2:38 a.m. ET and lasted six hours.
The outage ended at about 8:30 a.m. ET, with "limited" resumption of flights — but not until more than 300 flights had been canceled.
Customers heading to the airport should expect delays and cancellations, Delta warned.
The airline is allowing passengers to rebook for travel as late as Friday to avoid the chaos.
