These figures cover 845 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
SkyWest against every carrier on SBN to DFW
SkyWest flew 845 of the 984 flights on SBN to DFW, most of the route. Its 73.6% on time is about level with the route as a whole at 72.2%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from SkyWest at 73.6% to PSA at 63.6%. 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 SkyWest 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 845 flights.
- 5am–8am324 flights73.7%
- 8am–11am41 flights75.0%
- 11am–2pm124 flights77.9%
- 2pm–5pm116 flights71.1%
- 5pm–8pm240 flights72.1%
- 8pm–5am—
Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 77.9% on time, ahead of 2pm–5pm at 71.1%. 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 5am–8am window is the busiest, with 324 flights scheduled in it.
Across the year
SkyWest on SBN to DFW through the year
January is the weak month at 65.5% on time, against 83.9% in September. 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. October was the busiest month here, with 93 flights.
Across the week, Tuesday is the strongest day at 81.8% on time and Monday the weakest at 66.7%. 15 points is a smaller lever than departure hour, but it is free.
Delay causes
Why SkyWest runs late on this route
One category carries most of the weight here. Carrier accounts for 49% of the 23,000 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.
- 49%Carrier
- 27%Extreme weather
- 15%Late-arriving aircraft
- 9%National Airspace System
- 0%Security
Extreme weather accounts for 27% 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 4.3 times the usual weather exposure. The split is drawn from 22,508 reported delay minutes.
The largest share of delay minutes, 49%, 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 11,000 of the 23,000 delay minutes reported here.
Cancellations sit at 2.25% against a national 1.81%, which is ordinary. Diversions add another 0.59%.
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.
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 runs 74.1% on time across 845 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 845 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 SkyWest on SBN to DFW
Put together: treat all of this as provisional. 845 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 73.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 821 completed flights over 12 months sit behind that.
