Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.

SkyWest on SAT to DFW lands a B−, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 2.2 hours on average. That is a workable record, not a spotless one. That rests on 367 flights. The strongest carrier on the route with a full sample, American Airlines, flew 3,550 at 77.4% on time.

The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on SAT 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 SAT to DFW, 4,382 flights

These figures cover 367 flights between July 2025 and June 2026. Beyond the headline rate, 11.0% 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 SAT to DFW

SkyWest flew 367 of the 4,382 flights on SAT to DFW, about 8% of it. Its 80.8% on time is 4 points better than the route as a whole, which runs 77.1%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from PSA at 100.0% to Envoy at 71.3%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. American Airlines arrives on time 77.4% of the time; Envoy Air manages 71.3%. Sample sizes sit next to every figure, because a two-point gap across 460 flights means less than a ten-point one.

On-time performance by carrier on SAT to DFW
Airline	Flights	On time	Avg delay	Cancelled	Grade
PSA Airlinesthin sample	5	100.0%	—	0.00%	A+
SkyWest Airlines (this page)	367	80.8%	133 min	3.27%	B−
American Airlines	3,550	77.4%	107 min	3.46%	B−
Envoy Air	460	71.3%	79 min	3.70%	C−

Envoy Air cancels 3.7% 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 SkyWest runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

8am–11am—
11am–2pm292 flights84.0%
2pm–5pm17 flights—
5pm–8pm25 flights—
8pm–5am33 flights63.3%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 63.3% on time, against 84.0% for the 11am–2pm slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 11am–2pm window is the busiest, with 292 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 80.8% on time across 367 flights.

SkyWest on SAT to DFW did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.1% on time and its weakest Jul–Sep 2025 at 72.2%, a swing of 18 points on roughly 92 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, Tuesday is the strongest day at 91.8% on time and Saturday the weakest at 69.1%. 23 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. Extreme weather accounts for 50% of the 9,009 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.

Extreme weather accounts for 50% 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 8.0 times the usual weather exposure. The split is drawn from 9,009 reported delay minutes.

Cancellations run at 3.27%, against 1.81% nationally. That is about one flight in 30 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. 11.0% 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 247 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 runs 83.7% on time across 367 flights, within 3 points 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. 367 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 SAT to DFW

Put together: the delay figures matter less here than the 3.27% cancellation rate. A late arrival costs you about 2.2 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. 355 completed flights over 12 months sit behind that.
