Envoy on DFW to SAT sits in the middle of the pack with a B−. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land about 55 minutes behind schedule. That rests on 460 flights. The strongest carrier on the route with a full sample, SkyWest Airlines, flew 367 at 83.7% on time.

The US average over the same twelve months is 77.6%, so there is little to separate Envoy on DFW to SAT 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 SAT, 4,383 flights

These figures cover 460 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

Envoy against every carrier on DFW to SAT

Envoy flew 460 of the 4,383 flights on DFW to SAT, about 10% of it. Its 75.8% on time is 9 points better than the route as a whole, which runs 67.0%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from SkyWest at 83.7% to American at 64.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 83.7% of the time; American Airlines manages 64.1%. Sample sizes sit next to every figure, because a two-point gap across 3,551 flights means less than a ten-point one.

On-time performance by carrier on DFW to SAT
Airline	Flights	On time	Avg delay	Cancelled	Grade
SkyWest Airlines	367	83.7%	72 min	3.00%	B
PSA Airlinesthin sample	5	80.0%	15 min	0.00%	B+
Envoy Air (this page)	460	75.8%	54 min	3.48%	B−
American Airlines	3,551	64.1%	82 min	3.55%	D−

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 matters more here than the choice of carrier. The gap between the best and worst window is 11 points, against 20 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

8am–11am72 flights74.3%
11am–2pm36 flights77.1%
2pm–5pm248 flights79.2%
5pm–8pm95 flights68.5%

Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 2pm–5pm slot at 79.2% on time, ahead of 5pm–8pm at 68.5%. 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 2pm–5pm window is the busiest, with 248 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 75.8% on time across 460 flights.

Envoy on DFW to SAT did not run the same all year. Its best quarter was Jan–Mar 2026 at 89.2% on time and its weakest Apr–Jun 2026 at 73.8%, a swing of 15 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, Tuesday is the strongest day at 84.5% on time and Sunday the weakest at 67.2%. 17 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 53% of the 5,801 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
53%
National Airspace System
22%
Carrier
19%
Extreme weather
6%

53% 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 5,801 reported delay minutes here, that single category outweighs weather by 9 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 5,801 reported delay minutes.

Cancellations run at 3.48%, 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

6.8% 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 55 minutes, which a normal layover absorbs.

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 2pm–5pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 71.3% on time across 460 flights, 5 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 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 DFW to SAT

Put together: the delay figures matter less here than the 3.48% cancellation rate. A late arrival costs you about 55 minutes; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 443 completed flights over 12 months sit behind that.
