Dense Fog Forces Flight Delays and Ground Stops at Atlanta’s Hartsfield-Jackson
Dense fog blanketing the Atlanta metropolitan area Monday morning led to widespread flight delays and a weather-related ground stop at Hartsfield-Jackson Atlanta International Airport, the nation’s busiest air hub, disrupting travel plans for thousands of passengers across the southeastern United States.
The Federal Aviation Administration (FAA) issued a weather-related ground stop early Monday, halting departures at Hartsfield-Jackson from approximately 7:49 a.m. EST as low ceilings and poor visibility limited aircraft operations. The ground stop was initially expected to remain in place until at least 9:00 a.m. and was later extended through 10:00 a.m. as the dense fog advisory persisted, according to aviation and weather officials.
Major Delays and Cancellations Reported
As of late morning, flight tracking data showed more than 500 delays and at least 40 cancellations at Hartsfield-Jackson. Delays were averaging approximately 25–45 minutes as airlines adjusted schedules and flight crews managed the backlog. (FOX 5 Atlanta)
Delta Air Lines — which operates a large hub at Atlanta — reported the highest number of disruptions, with roughly 340 delayed flights and more than 20 cancellations attributed to the weather conditions.
A ground stop does not prevent incoming aircraft already en route from landing, but incoming flights may face delays if airport conditions deteriorate further, creating ripple effects throughout airline networks.
Fog Advisory and Weather Conditions
The National Weather Service issued a dense fog advisory for the Atlanta region, with visibility reduced to as little as a quarter-mile in some areas. This low visibility can greatly diminish pilots’ ability to see runways and taxiways during takeoffs and landings, requiring additional spacing and procedural adjustments for flight crews and air-traffic controllers.
By mid-morning, the worst of the fog began to lift, and the FAA lifted the ground stop, allowing operations at Hartsfield-Jackson to resume gradually as the advisory period expired.
Travelers experienced long waits at terminals and flight gates as airlines worked to reorganize departure boards and manage passenger connections. Even after the fog cleared, residual delays often persist because aircraft and crew schedules must be realigned following the morning disruption.
Flights leaving Atlanta connect to destinations nationwide, meaning early-day disruptions at a major hub such as Hartsfield-Jackson can produce cascading delays in other parts of the U.S. air travel system.
Travel Advice For Passengers
Officials and airline representatives urged passengers scheduled to fly to or from Atlanta today to:
- Check flight status with their airline before heading to the airport;
- Allow extra time at the terminal to accommodate potential delays; and
- Be prepared for continued adjustments throughout the day as operations recover.
Dense fog and its effects on aviation are a known challenge for airports, particularly during the cooler morning hours, and institutions like the FAA use ground stops and other control measures to ensure the safety of pilots and passengers when visibility drops below operational thresholds.
