Carrier by carrier
American against every carrier on SDF to DFW
American flew 1,186 of the 1,994 flights on SDF to DFW, most of the route. Its 72.9% on time is 3 points worse than the route as a whole, which runs 76.0%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Envoy at 81.2% to American at 72.9%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: about a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Envoy Air | 389 | 81.2% | 65 min | 1.29% | B |

| American Airlines (this page) | 1,186 | 72.9% | 111 min | 3.12% | C− |
PSA Airlines cancels 4.6% 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 49 points, against about a point between the best and worst carrier.

- 8am–11am152 flights77.2%

The 8pm–5am window is where this operation falls apart: 34.4% on time, against 83.0% 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 5am–8am window is the busiest, with 477 flights scheduled in it.
Across the year
American on SDF to DFW through the year
July is the worst month at 60.0% on time, 26 points below February, the best at 85.6%. 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. April was the busiest month here, with 125 flights.

Share of 1,145 completed flights by arrival against schedule.
55 of 306 late departures made up the time and arrived on time, 18% of them. In the other direction, 59 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DFW.
The worst days
Worst days for American on SDF to DFW
The latest arrival of the period was on 29 January 2026, 55 hours 39 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 January 2026 | 55 hours 39 minutes | Carrier |
| 6 December 2025 | 43 hours 37 minutes | Carrier |

Delay causes
Why American runs late on this route
Carrier accounts for 48% of the 34,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 39%Late-arriving aircraft
- 11%National Airspace System
- 2%Extreme weather
- 0%Security
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 34,000 reported delay minutes here, that single category outweighs weather by 20 to one. The split is drawn from 34,403 reported delay minutes.
The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 16,000 of the 34,000 delay minutes reported here.
Cancellations run at 3.12%, 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
11.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 733 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.
The return leg is a different operation and performs like one: it runs 62.1% on time across 1,184 flights, 11 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 11 points of difference.
The sample behind these figures is 1,186 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 SDF to DFW
Put together: the delay figures matter less here than the 3.12% cancellation rate. A late arrival costs you close to two hours; 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. 1,145 completed flights over 12 months sit behind that.
