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 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 1,589 GNV to ATL flights, with a median arrival 17 minutes early.
Best time to fly GNV to ATL: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 91.6% of the time and Wednesday flights 91.8%, against 87.4% for the route overall.
Set against the rest of the country, this route's record is 10 points better than the US average of 77.6%. That gap is worth roughly 98 fewer late arrivals for every thousand flights.

These figures cover 1,589 flights between July 2025 and June 2026. The median arrival is 17 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.
Carrier by carrier
Which airline is most reliable on GNV to ATL
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Flights on GNV to ATL
The flight numbers below flew this route at least 250 times in the period, busiest first. Each has its own record, with its schedule and delay causes.
Departure window
The best time of day to leave
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 1,589 flights.
- 5am–8am365 flights91.6%
- 8am–11am308 flights90.4%
- 11am–2pm286 flights86.1%
- 2pm–5pm229 flights83.3%
- 5pm–8pm400 flights84.5%
- 8pm–5am1 flights—
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.6% of the time, against 83.3% for the afternoon window. That is 8 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 400 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 14 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.
September is the best month on the calendar at 94.9% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. May was the busiest month here, with 149 flights.
Across the week, Wednesday is the strongest day at 91.8% on time and Sunday the weakest at 81.7%. 10 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
One category carries most of the weight here. Carrier accounts for 61% of the 20,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 61%Carrier
- 26%Late-arriving aircraft
- 7%Extreme weather
- 5%National Airspace System
The largest share of delay minutes, 61%, 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 13,000 of the 20,000 delay minutes reported here. The split is drawn from 20,479 reported delay minutes.
Cancellations sit at 1.83% against a national 1.81%, which is ordinary. Diversions add another 0.06%.
Connections and stage length
What a delay here actually costs
6.0% of arrivals land an hour or more late, close to the national 8.1%. 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 close to two hours, which a normal layover absorbs.
At 300 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 runs 84.7% on time across 1,589 flights, within 3 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,589 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 94.9% on time and March 81.2%, a swing of 14 points. If the dates move at all, move them out of March before you think about anything else. 1,559 completed flights over 12 months sit behind that.
Common questions
GNV to ATL questions
How often is GNV 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 12.6% of the 1,589 flights in this analysis, against 22.4% nationally. Delayed flights are late by close to two hours on average.
How reliable is GNV to ATL compared with the rest of the country?
87.4% of flights arrive on time here against a national 77.6%, 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 GNV to ATL?
The 5am–8am departure window is the strongest at 91.6% on time. The 2pm–5pm window is the weakest at 83.3%, 8 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 March delays on GNV to ATL?
March is the weakest month at 81.2% on time, compared with 94.9% in September. Across the year that is 14 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
