ATL across all twelve months
These figures cover 25,888 departures from Hartsfield-Jackson Atlanta International in November 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.
Against the year
November next to ATL's other months
Against ATL's own year, November ran 2 points better than the twelve-month rate of 78.4%, which makes it number four of twelve months, best first. Either side of it, October ran 81.6% on time and December 73.2%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window
The best time of day to leave ATL in November
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,625 flights90.3%
- 8am–11am5,562 flights84.5%
- 11am–2pm4,174 flights84.6%
- 2pm–5pm5,022 flights78.7%
- 5pm–8pm4,052 flights75.5%
- 8pm–5am5,453 flights74.8%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 90.3% of the time, against 74.8% for the overnight window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 5,562 flights scheduled in it.
Across the week, Wednesday is the strongest day at 90.5% on time and Sunday the weakest at 71.7%. 19 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at ATL in November
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 82.1% of the time; Frontier Airlines manages 66.0%. Sample sizes sit next to every figure, because a two-point gap across 1,551 flights means less than a ten-point one.

SkyWest Airlines cancels 7.8% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
What held ATL up in November
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 326,000 reported delay minutes.
- 38%Carrier
- 30%Late-arriving aircraft
- 27%National Airspace System
- 4%Extreme weather
- 0%Security
The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 125,000 of the 326,000 delay minutes reported here. The split is drawn from 326,106 reported delay minutes.
Cancellations sit at 2.45% against a national 2.49%, which is ordinary. Diversions add another 0.17%.
6.8% of arrivals land an hour or more late, close to the national 7.8%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
