American on GSP to CLT 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 8 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 279 flights, with a median arrival 10 minutes early.

Set against the rest of the country, American's GSP to CLT record is 8 points better than the US average of 77.3%. That gap is worth roughly 83 fewer late arrivals for every thousand flights.

These figures cover 279 flights between September 2025 and August 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 GSP to CLT

American flew 279 of the 1,538 flights on GSP to CLT, about 18% of it. Its 85.6% on time is 3 points better than the route as a whole, which runs 82.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from American at 85.6% to Envoy at 78.8%. One 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 13 points, against half a point between the best and worst carrier.

  • 5am–8am135 flights90.2%
  • 8am–11am49 flights93.3%
  • 11am–2pm69 flights80.3%

  • 5pm–8pm—
  • 8pm–5am4 flights—

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 80.3% on time against 93.3% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 5am–8am window is the busiest, with 135 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 85.6% on time across 279 flights.

American on GSP to CLT did not run the same all year. Its best quarter was Apr–Jun 2026 at 100.0% on time and its weakest Oct–Dec 2025 at 81.3%, a swing of 19 points on roughly 70 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Wednesday is the strongest day at 92.5% on time and Sunday the weakest at 77.8%, a spread of 15 points.

Delay causes

Why American runs late on this route

Late-arriving aircraft accounts for 57% of the 3,481 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    57%
  • Carrier
    34%
  • National Airspace System
    6%
  • Extreme weather
    4%

57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,481 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 3,481 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 93.3% on time here.

Cancellations run at 3.23%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and stage length

What a delay here costs

7.4% 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 75 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 8am–11am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 81.1% on time across 279 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.

One caution: this is a thin sample. 279 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 GSP to CLT

Put together: the delay figures matter less here than the 3.23% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 270 completed flights over 12 months sit behind that.
