Delta flights resume after computer systems outage

Delta Air Lines flights gradually resumed after an outage hit its computer systems, grounding planes and stranding passengers of one of the world’s largest carriers at airports around the globe.

Atlanta-based Delta, the second-largest US carrier by passenger traffic, said it had cancelled about 300 flights after a power outage that began around 2.30am in Atlanta.

The power interruption caused a “system-wide outage,” Delta said. At about 10.30am, it said about 800 of its nearly 6,000 scheduled flights had taken off.
