The Federal Aviation Administration issued a ground stop at Hartsfield-Jackson Atlanta International Airport on July 12, 2026, due to thunderstorms affecting the area. Originally set to last until 2:30 p.m., the ground stop was extended until 4 p.m. before being lifted later in the day. Multiple counties in eastern Georgia remained under a severe thunderstorm watch until 9 p.m.
Flight Delays and Operational Impact
The ground stop resulted in more than 900 flight delays as of about 1 p.m. Central to the disruption, flights experienced an average delay time of roughly 40 minutes, with some delays reaching as long as 75 minutes. These delays affected
