Flying home for the holidays was more of a headache than usual for those traveling through the Atlanta airport on Sunday.
Hartsfield-Jackson International Airport in Atlanta — the busiest airport in the world — lost power on Sunday reportedly leaving some passengers trapped in planes and inside the airport terminals.
The airport confirmed the outage on Twitter, and the FAA said they put a ground stop in place, which means they slowed or halted inbound air traffic.
Airport officials told NBC News that electrical issues at a Georgia substation “has impacted the power at the airport.”
Airport officials said Georgia Power sent repair teams to the scene to work on the issue, and they had been there since 1:30 p.m. ET.
