PSA on DFW to SWO sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land close to two hours behind schedule. That rests on 399 flights, with a median arrival 7 minutes early.
The national on-time rate over the same period is 77.6%, so PSA on DFW to SWO runs 4 points behind the country as a whole. Across a thousand flights that is about 44 extra late arrivals.

Every carrier on DFW to SWO, 729 flights
These figures cover 399 flights between July 2025 and June 2026. Beyond the headline rate, 11.7% 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
PSA against every carrier on DFW to SWO
PSA flew 399 of the 729 flights on DFW to SWO, most of the route. Its 73.2% on time is 4 points worse than the route as a whole, which runs 76.8%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from SkyWest at 81.0% to PSA at 73.2%. One 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 PSA runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 399 flights.
- 5am–8am—
- 8am–11am—
- 11am–2pm200 flights75.9%
- 2pm–5pm—
- 5pm–8pm3 flights—
- 8pm–5am196 flights70.9%
Scale runs 60% to 80%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 75.9% on time, ahead of 8pm–5am at 70.9%. 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 200 flights scheduled in it.
Across the year

- Oct–Dec 2025119 flights57.4%

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 73.2% on time across 399 flights.
PSA on DFW to SWO did not run the same all year. Its best quarter was Apr–Jun 2026 at 80.6% on time and its weakest Oct–Dec 2025 at 57.4%, a swing of 23 points on roughly 133 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Monday is the strongest day at 84.9% on time and Saturday the weakest at 63.5%. 21 points is a smaller lever than departure hour, but it is free.
Delay causes
Why PSA runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 10,000 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
- 27%Carrier
- 16%Extreme weather
- 4%National Airspace System
Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.6 times the usual weather exposure. The split is drawn from 10,057 reported delay minutes.
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 10,000 reported delay minutes here, that single category outweighs weather by 3 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.
Cancellations run at 6.52%, against 1.81% nationally. That is about one flight in fifteen 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. 11.7% 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 225 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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 79.0% on time across 399 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 399 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 DFW to SWO
Put together: the delay figures matter less here than the 6.52% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 369 completed flights over 12 months sit behind that.
