These figures cover 474 flights between July 2025 and June 2026. Beyond the headline rate, 11.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
American against every carrier on CLT to GSO
American flew 474 of the 1,170 flights on CLT to GSO, about 41% of it. Its 73.0% on time is 6 points worse than the route as a whole, which runs 78.9%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Envoy at 85.2% to American at 73.0%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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.

Departure window
When American runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am14 flights—
- 11am–2pm67 flights84.8%
- 2pm–5pm141 flights70.5%
- 5pm–8pm144 flights67.4%
- 8pm–5am108 flights75.7%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 84.8% on time, ahead of 5pm–8pm at 67.4%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5pm–8pm window is the busiest, with 144 flights scheduled in it.
Across the year

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 73.0% on time across 474 flights.
Quarter by quarter American on CLT to GSO held fairly steady: 76.0% in Jul–Sep 2025, 72.8% in Oct–Dec 2025 and 68.8% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
Across the week, Sunday is the strongest day at 81.6% on time and Friday the weakest at 66.2%. 15 points is a smaller lever than departure hour, but it is free.
Delay causes
Why American runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 60% of the 8,414 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.
- 60%Late-arriving aircraft
- 29%Carrier
- 6%National Airspace System
- 5%Extreme weather
60% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 8,414 reported delay minutes here, that single category outweighs weather by 12 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 8,414 reported delay minutes.
Cancellations sit at 1.48% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 84 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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 80.8% on time across 475 flights, 8 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 8 points of difference.
One caution: this is a thin sample. 474 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 American on CLT to GSO
Put together: treat all of this as provisional. 474 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 73.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 467 completed flights over 12 months sit behind that.
