Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.

American on GSO to CLT lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 475 flights, with a median arrival 10 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate American on GSO to CLT from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 475 flights between July 2025 and June 2026. The median arrival is 10 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

American against every carrier on GSO to CLT

American flew 475 of the 1,170 flights on GSO to CLT, about 41% of it. Its 80.8% on time is 5 points worse than the route as a whole, which runs 85.4%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Envoy at 90.8% to American at 80.8%. 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 20 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

8am–11am2 flights—
11am–2pm14 flights—
2pm–5pm90 flights82.2%
5pm–8pm206 flights73.8%
8pm–5am39 flights74.4%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.4% of the time, against 73.8% for the evening window. That is 20 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 206 flights scheduled in it.

Across the year

American on GSO to CLT through the year

Jul–Sep 2025232 flights84.3%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 80.8% on time across 475 flights.

Quarter by quarter American on GSO to CLT held fairly steady: 84.3% in Jul–Sep 2025, 76.8% in Oct–Dec 2025 and 77.7% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Saturday is the strongest day at 88.1% on time and Friday the weakest at 72.7%. 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 66% of the 6,893 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.

66% 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 6,893 reported delay minutes here, that single category outweighs weather by 8 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 6,893 reported delay minutes.

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 93.4% on time here.

Cancellations sit at 1.47% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

7.5% 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 a little over an hour, which a normal layover absorbs.

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 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 73.0% on time across 474 flights, 8 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 8 points of difference.

One caution: this is a thin sample. 475 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 GSO to CLT

Put together: treat all of this as provisional. 475 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 80.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 468 completed flights over 12 months sit behind that.
