Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on SDF to DFW 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 about an hour on average. That rests on 389 flights. The strongest carrier on the route with a full sample, PSA Airlines, flew 389 at 80.0% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on SDF to DFW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on SDF to DFW, 1,994 flights
These figures cover 389 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
Envoy against every carrier on SDF to DFW
Envoy flew 389 of the 1,994 flights on SDF to DFW, about 20% of it. Its 81.2% on time is 5 points better than the route as a whole, which runs 76.0%. Ranked by on-time rate it is first 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 choice of carrier is not cosmetic here. PSA Airlines arrives on time 80.0% of the time; American Airlines manages 72.9%. Sample sizes sit next to every figure, because a two-point gap across 1,186 flights means less than a ten-point one.

| Envoy Air (this page) | 389 | 81.2% | 65 min | 1.29% | B |

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 Envoy runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 18 points, against 7 points between the best and worst carrier.
- 5am–8am2 flights—
- 8am–11am9 flights—
- 11am–2pm154 flights89.5%
- 2pm–5pm120 flights77.6%
- 5pm–8pm104 flights71.6%
- 8pm–5am—
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 89.5% on time, ahead of 5pm–8pm at 71.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 154 flights scheduled in it.

| Date | Arrived late by | Largest filed cause |

Delay causes
Why Envoy runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,678 reported delay minutes.
- 40%Late-arriving aircraft
- 36%National Airspace System
- 18%Carrier
- 6%Extreme weather
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,678 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 4,678 reported delay minutes.
36% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,680 minutes out of 4,678, against a national NAS share of 21%.
Cancellations sit at 1.29% against a national 1.89%, which is ordinary. Diversions add another 0.51%.
Connections and stage length
What a delay here costs
6.8% 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 about an hour, which a normal layover absorbs.
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 89.1% on time across 389 flights, 8 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 8 points of difference.
One caution: this is a thin sample. 389 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 Envoy on SDF to DFW
Put together: treat all of this as provisional. 389 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 81.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 382 completed flights over 12 months sit behind that.
