The 8pm–5am window is where this operation falls apart: 49.5% on time, against 81.7% for the 8am–11am slot.

Across the year
When delays peak on this route
This route's year swings by 25 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
July is the worst month at 50.0% on time, 25 points below November, the best at 75.4%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. May was the busiest month here, with 112 flights.
Across the week, Tuesday is the strongest day at 72.6% on time and Sunday the weakest at 58.7%, a spread of 14 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 54% of the 27,000 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 33%Carrier
- 7%National Airspace System
- 5%Extreme weather
- 0%Security
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 27,000 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 27,331 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 81.7% on time here.
Cancellations run at 2.74%, against 1.89% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here actually costs
14.6% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 925 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 76.3% on time across 1,022 flights, 10 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 10 points of difference.
One caution: this is a thin sample. 1,023 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this
Booking this route
Put together: treat all of this as provisional. 1,023 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 65.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 994 completed flights over 12 months sit behind that.

The 8am–11am departure window is the strongest at 81.7% on time. The 8pm–5am window is the weakest at 49.5%, 32 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are July delays on DFW to SAV?
