Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on SDF to DFW lands a B−, 3 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 2.8 hours on average. That rests on 389 flights. The strongest carrier on the route with a full sample, Envoy Air, flew 389 at 81.2% on time.
The US average over the same twelve months is 77.3%, so there is little to separate PSA on SDF to DFW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
PSA against every carrier on SDF to DFW
PSA flew 389 of the 1,994 flights on SDF to DFW, about 20% of it. Its 80.0% on time is 4 points better than the route as a whole, which runs 76.0%. Ranked by on-time rate it is number two 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. Envoy Air arrives on time 81.2% 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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Envoy Air | 389 | 81.2% | 65 min | 1.29% | B |
| PSA Airlines (this page) | 389 | 80.0% | 166 min | 4.63% | B− |

| American Airlines | 1,186 | 72.9% | 111 min | 3.12% | C− |
American Airlines cancels 3.1% 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 PSA runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against 8 points between the best and worst carrier.
- 5am–8am—
- 8am–11am—
- 11am–2pm109 flights81.1%
- 2pm–5pm177 flights85.5%
- 5pm–8pm4 flights—
- 8pm–5am99 flights69.1%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 2pm–5pm slot at 85.5% on time, ahead of 8pm–5am at 69.1%. 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 2pm–5pm window is the busiest, with 177 flights scheduled in it.
Across the year
PSA on SDF to DFW through the year
December is the weak month at 73.9% on time, against 90.6% in January. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. April was the busiest month here, with 53 flights.
Across the week, Wednesday is the strongest day at 86.5% on time and Saturday the weakest at 68.0%, a spread of 19 points.
Arrival by arrival
How late PSA on SDF to DFW runs when it is late

The worst days
Worst days for PSA on SDF to DFW
The latest arrival of the period was on 4 December 2025, 24 hours 34 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 |
|---|---|---|
| 4 December 2025 | 24 hours 34 minutes | Carrier |
| 17 April 2026 | 21 hours 8 minutes | Carrier |
| 6 November 2025 | 19 hours 41 minutes | Carrier |

Delay causes
Why PSA runs late on this route
Carrier accounts for 52% of the 12,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 31%Late-arriving aircraft
- 8%Extreme weather
- 8%National Airspace System
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 6,434 of the 12,000 delay minutes reported here. The split is drawn from 12,266 reported delay minutes.
Cancellations run at 4.63%, against 1.89% nationally. That is about one flight in twenty 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
8.1% 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 2.8 hours, 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 83.1% on time across 389 flights, 3 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 3 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 PSA on SDF to DFW
Put together: the delay figures matter less here than the 4.63% cancellation rate. A late arrival costs you about 2.8 hours; 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. 370 completed flights over 12 months sit behind that.
