Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.
American on DFW to GSP draws a D−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 726 flights, with a median arrival 2 minutes late.
The national on-time rate over the same period is 77.6%, so American on DFW to GSP runs 13 points behind the country as a whole. Across a thousand flights that is about 131 extra late arrivals.

These figures cover 726 flights between July 2025 and June 2026. Beyond the headline rate, 12.5% 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 DFW to GSP
American flew 726 of the 1,176 flights on DFW to GSP, most of the route. Its 64.5% on time is 7 points worse than the route as a whole, which runs 71.6%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from PSA at 85.3% to American at 64.5%. 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 25 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–11am2 flights—
- 11am–2pm332 flights68.9%
- 2pm–5pm33 flights71.9%
- 5pm–8pm263 flights63.9%
- 8pm–5am96 flights47.3%
Scale runs 40% to 75%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 47.3% on time, against 71.9% for the 2pm–5pm slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 11am–2pm window is the busiest, with 332 flights scheduled in it.
Across the year
American on DFW to GSP through the year
July is the worst month at 36.7% on time, 46 points below September, the best at 82.8%. 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. October was the busiest month here, with 63 flights.
Across the week, Tuesday is the strongest day at 71.2% on time and Sunday the weakest at 50.5%. 21 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 53% of the 17,000 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.
- 53%Late-arriving aircraft
- 27%Carrier
- 11%Extreme weather
- 10%National Airspace System
53% 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 17,000 reported delay minutes here, that single category outweighs weather by 5 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 16,518 reported delay minutes.
Cancellations run at 3.58%, against 1.81% 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.5% 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.
The 862 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 73.6% on time across 726 flights, 9 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 9 points of difference.
One caution: this is a thin sample. 726 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 DFW to GSP
Put together: the delay figures matter less here than the 3.58% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 695 completed flights over 12 months sit behind that.
