On-Time Performance and Cancellations

Departure On-Time Performance: 75.30%

Year-over-Year Change in On-Time Performance: -1.39 percentage points

Cancelled Flights: 108

Year-over-Year Change in Cancellations: -71.43%

Departure punctuality at Hartsfield–Jackson Atlanta International Airport reached 75.30%, with a -1.39 percentage‑point change versus last year as afternoon convective weather and brief air‑traffic flow programs created pockets of delay. Only 108 departures were cancelled (-71.43% year over year), reducing severe disruption for most travelers; adding a modest buffer is still wise on Friday–Sunday peaks.

Airlines Serving ATL

Hartsfield–Jackson Atlanta International Airport is the primary hub for Delta Air Lines and is also served by other major U.S. and international carriers, offering dense domestic coverage and long‑haul links to Europe and Latin America. The network emphasizes high‑frequency domestic spokes with timed banks that support connections across the Southeast and beyond.

Outlook

Over the next 4–8 weeks, schedules at the hub should remain dense but broadly stable, with departure on‑time performance near the current 75.30% range; afternoon thunderstorms and Friday–Sunday peaks are the primary risk windows. Passengers should prioritize morning departures, allow 60–90 minutes of buffer for security and connections on busy days, and monitor real‑time gate and weather alerts via the NextFly App.
