This route earns an A. More than four flights in five 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 close to two hours. That rests on 1,596 GNV to ATL flights, with a median arrival 16 minutes early.
Best time to fly GNV to ATL: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 92.2% of the time and Wednesday flights 91.5%, against 86.9% 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 96 fewer late arrivals for every thousand flights.

These figures cover 1,596 flights between September 2025 and August 2026. The median arrival is 16 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.

Book the early departure. Flights leaving between 5am–8am arrive on time 92.2% of the time, against 79.8% for the afternoon window. That is 12 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 410 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 15 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 79.6% on time, 15 points below September, the best at 94.9%. 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 149 flights.
Across the week, Wednesday is the strongest day at 91.5% on time and Sunday the weakest at 81.8%, a spread of 10 points.
Delay causes
Why this route gets delayed
Carrier accounts for 64% of the 22,000 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Carrier
- 23%Late-arriving aircraft
- 9%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 14,000 of the 22,000 delay minutes reported here. The split is drawn from 21,950 reported delay minutes.
Cancellations sit at 1.75% against a national 1.89%, which is ordinary. Diversions add another 0.06%.
Connections and stage length
What a delay here actually costs
6.3% 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 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 84.8% on time across 1,596 flights, within 2 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 1,596 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 July 79.6%, a swing of 15 points. If the dates move at all, move them out of July before you think about anything else. 1,567 completed flights over 12 months sit behind that.

The 5am–8am departure window is the strongest at 92.2% on time. The 2pm–5pm window is the weakest at 79.8%, 12 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 GNV to ATL?
