Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with American Airlines.
American on CLT to GSP lands a B−, 4 points better than the national rate of 77.3%. 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 rests on 279 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate American on CLT to GSP from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 279 flights between September 2025 and August 2026. The median arrival is 8 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 CLT to GSP
American flew 279 of the 1,539 flights on CLT to GSP, about 18% of it. Its 81.1% on time is 11 points better than the route as a whole, which runs 69.7%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Envoy at 84.1% to PSA at 64.9%. 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.

American on CLT to GSP did not run the same all year. Its best quarter was Apr–Jun 2026 at 93.0% on time and its weakest Oct–Dec 2025 at 72.7%, a swing of 20 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.

The worst days
Worst days for American on CLT to GSP
The latest arrival of the period was on 16 October 2025, 7 hours 5 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 October 2025 | 7 hours 5 minutes | Carrier |
| 30 November 2025 | 4 hours 57 minutes | Late-arriving aircraft |
| 23 November 2025 | 3 hours 53 minutes | Carrier |
| 14 December 2025 | 3 hours 10 minutes | Late-arriving aircraft |

Delay causes
Why American runs late on this route
Carrier accounts for 48% of the 3,780 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 42%Late-arriving aircraft
- 5%National Airspace System
- 4%Extreme weather
- 1%Security
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,780 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 3,780 reported delay minutes.
The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,815 of the 3,780 delay minutes reported 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
7.8% 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 a little over an hour, 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 8pm–5am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 85.6% on time across 279 flights, 5 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 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 CLT to GSP
Put together: the delay figures matter less here than the 3.23% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8pm–5am 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.
