Envoy on SAT to DFW sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 460 flights. The strongest carrier on the route with a full sample, SkyWest Airlines, flew 367 at 80.8% on time.

The national on-time rate over the same period is 77.6%, so Envoy on SAT to DFW runs 6 points behind the country as a whole. Across a thousand flights that is about 63 extra late arrivals.

These figures cover 460 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% 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

Envoy against every carrier on SAT to DFW

Envoy flew 460 of the 4,382 flights on SAT to DFW, about 10% of it. Its 71.3% on time is 6 points worse than the route as a whole, which runs 77.1%. Ranked by on-time rate it is last 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 two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

American Airlines cancels 3.5% 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 Envoy 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 460 flights.

  • 5am–8am1 flights
  • 8am–11am12 flights
  • 11am–2pm104 flights71.7%
  • 2pm–5pm115 flights71.2%
  • 5pm–8pm211 flights71.3%
  • 8pm–5am17 flights

Scale runs 65% to 75%. Rows with fewer than 30 flights show a dash.

The 11am–2pm window is the strongest at 71.7% on time. The full set of windows spans half a point.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 71.3% on time across 460 flights.

Envoy on SAT to DFW did not run the same all year. Its best quarter was Jan–Mar 2026 at 86.1% on time and its weakest Apr–Jun 2026 at 69.5%, a swing of 17 points on roughly 153 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, Thursday is the strongest day at 80.0% on time and Sunday the weakest at 60.3%. 20 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Envoy runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 47% 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.

  • Late-arriving aircraft
    47%
  • Extreme weather
    19%
  • Carrier
    17%
  • National Airspace System
    16%

Extreme weather accounts for 19% 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 3.1 times the usual weather exposure. The split is drawn from 10,028 reported delay minutes.

47% 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 2 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 3.70%, against 1.81% nationally. That is roughly 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% 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 is a different operation and performs like one: it runs 75.8% on time across 460 flights, 5 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 5 points of difference.

One caution: this is a thin sample. 460 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 Envoy on SAT to DFW

Put together: the delay figures matter less here than the 3.70% cancellation rate. A late arrival costs you a little over an hour; 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. 442 completed flights over 12 months sit behind that.
