Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on DFW to SBN sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 139 flights, with a median arrival 3 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate PSA on DFW to SBN from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on DFW to SBN, 984 flights
These figures cover 139 flights between July 2025 and June 2026. The median arrival is 3 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
PSA against every carrier on DFW to SBN
PSA flew 139 of the 984 flights on DFW to SBN, about 14% of it. Its 74.4% on time is about level with the route as a whole at 74.2%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from PSA at 74.4% to SkyWest at 74.1%.
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 139 flights.
There are not enough flights in each departure window to split PSA's DFW to SBN record by time of day without the percentages moving on noise. The headline rate of 74.4% is the reliable figure here.
Across the year
PSA on DFW to SBN through the year
- Jul–Sep 20255 flights—
- Oct–Dec 202544 flights66.7%
- Jan–Mar 20265 flights—
- Apr–Jun 202685 flights81.7%
Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 74.4% on time across 139 flights.
Split by quarter, PSA on DFW to SBN logged 5 flights in Jul–Sep 2025, 44 flights in Oct–Dec 2025, 5 flights in Jan–Mar 2026 and 85 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 74.4% annual figure is the one to use.
Delay causes
Why PSA runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 1,939 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.
- 45%Late-arriving aircraft
- 36%Carrier
- 16%National Airspace System
- 3%Extreme weather
45% 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 1,939 reported delay minutes here, that single category outweighs weather by 15 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 1,939 reported delay minutes.
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 703 of the 1,939 delay minutes reported here.
Cancellations run at 4.32%, against 1.81% nationally. That is about one flight in 25 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
7.5% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 846 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 63.6% on time across 139 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.
One caution: this is a thin sample. 139 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 SBN
Put together: the delay figures matter less here than the 4.32% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 133 completed flights over 12 months sit behind that.
