This route earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 3,064 SAV to ATL flights, with a median arrival 13 minutes early.
Best time to fly SAV to ATL: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 91.8% of the time and Wednesday flights 91.5%, against 87.1% for the route overall.
Set against the rest of the country, this route's record is 10 points better than the US average of 77.3%. That gap is worth roughly 98 fewer late arrivals for every thousand flights.

These figures cover 3,064 flights between September 2025 and August 2026. The median arrival is 13 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 10 points, against half a point between the best and worst carrier.
- 5am–8am727 flights91.8%
- 8am–11am682 flights90.7%
- 11am–2pm412 flights89.6%
- 2pm–5pm521 flights81.6%
- 5pm–8pm578 flights81.5%
- 8pm–5am144 flights82.4%
Scale runs 75% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.8% of the time, against 81.5% for the evening window. That is 10 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 727 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 22 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 73.2% on time, 22 points below September, the best at 95.0%. 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 290 flights.
Across the week, Wednesday is the strongest day at 91.5% on time and Sunday the weakest at 80.8%, a spread of 11 points.
Delay causes
Why this route gets delayed
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 34,000 reported delay minutes.
- 40%Carrier
- 34%Late-arriving aircraft
- 14%Extreme weather
- 12%National Airspace System
Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.4 times the usual weather exposure. The split is drawn from 34,193 reported delay minutes.
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 14,000 of the 34,000 delay minutes reported here.
Cancellations sit at 1.63% against a national 1.89%, which is ordinary. Diversions add another 0.13%.
Connections and stage length
What a delay here actually costs
5.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
At 215 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 82.1% on time across 3,064 flights, 5 points below 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 5 points of difference.
The sample behind these figures is 3,064 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 95.0% on time and July 73.2%, a swing of 22 points. If the dates move at all, move them out of July before you think about anything else. 3,010 completed flights over 12 months sit behind that.
Common questions
SAV to ATL questions
How often is SAV to ATL delayed?
About one flight in eight arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 12.9% of the 3,064 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is SAV to ATL compared with the rest of the country?
87.1% of flights arrive on time here against a national 77.3%, a difference of 10 points in its favour. That is worth a A on this site's grading scale.
What time of day has the fewest delays on SAV to ATL?
The 5am–8am departure window is the strongest at 91.8% on time. The 5pm–8pm window is the weakest at 81.5%, 10 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 SAV to ATL?
July is the weakest month at 73.2% on time, compared with 95.0% in September. Across the year that is 22 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
