Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.
American on DFW to SAT carries a cancellation problem, not just a delay problem: 3.5% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, about two flights in three arrive on time, worth a D− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 3,551 flights. The strongest carrier on the route with a full sample, SkyWest Airlines, flew 367 at 83.7% on time.
The national on-time rate over the same period is 77.6%, so American on DFW to SAT runs 14 points behind the country as a whole. Across a thousand flights that is about 135 extra late arrivals.

These figures cover 3,551 flights between July 2025 and June 2026. Beyond the headline rate, 15.0% 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 SAT
American flew 3,551 of the 4,383 flights on DFW to SAT, most of the route. Its 64.1% on time is 3 points worse than the route as a whole, which runs 67.0%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from SkyWest at 83.7% to American at 64.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 83.7% of the time; Envoy Air manages 75.8%. Sample sizes sit next to every figure, because a two-point gap across 460 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |

| SkyWest Airlines | 367 | 83.7% | 72 min | 3.00% | B |
| PSA Airlinesthin sample | 5 | 80.0% | 15 min | 0.00% | B+ |

| American Airlines (this page) | 3,551 | 64.1% | 82 min | 3.55% | D− |
Envoy Air cancels 3.5% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 30 points, against 8 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am325 flights84.0%
- 8am–11am496 flights77.5%
- 11am–2pm498 flights70.6%
- 2pm–5pm525 flights60.1%
- 5pm–8pm747 flights57.8%
- 8pm–5am960 flights53.9%
Scale runs 45% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 53.9% on time, against 84.0% for the 5am–8am 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 8pm–5am window is the busiest, with 960 flights scheduled in it.
Across the year
American on DFW to SAT through the year
June is the worst month at 48.2% on time, 29 points below February, the best at 77.4%. 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. March was the busiest month here, with 333 flights.
Across the week, Wednesday is the strongest day at 68.7% on time and Sunday the weakest at 54.0%. 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 52% of the 100,000 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.
- 52%Late-arriving aircraft
- 34%Carrier
- 8%Extreme weather
- 7%National Airspace System
- 0%Security
52% 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 100,000 reported delay minutes here, that single category outweighs weather by 7 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 100,487 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 84.0% on time here.
Cancellations run at 3.55%, 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. 15.0% 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 247 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 77.4% on time across 3,550 flights, 13 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 13 points of difference.
The sample behind these figures is 3,551 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking American on DFW to SAT
Put together: the delay figures matter less here than the 3.55% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 3,421 completed flights over 12 months sit behind that.
