(FOX NEWS) — Power has been fully restored at the Hartsfield-Jackson Atlanta International Airport after a complete power outage grounded flights Sunday afternoon, causing a holiday travel nightmare for fliers across the country just over a week before Christmas.

Kasim Reed, the city’s mayor, announced the power update on Twitter after the power outage forced the Federal Aviation Administration to suspend outgoing flights and implement a “ground stop” for incoming flights, which “means that flights headed to Atlanta are held on the ground at their departure airport.”
