Envoy on DFW to COS earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 254 flights. The strongest carrier on the route with a full sample, SkyWest Airlines, flew 610 at 72.4% on time.

Set against the rest of the country, Envoy's DFW to COS record is 10 points better than the US average of 77.6%. That gap is worth roughly 100 fewer late arrivals for every thousand flights.

Every carrier on DFW to COS, 1,934 flights

These figures cover 254 flights between July 2025 and June 2026. The median arrival is 10 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 COS

Envoy flew 254 of the 1,934 flights on DFW to COS, about 13% of it. Its 87.6% on time is 17 points better than the route as a whole, which runs 70.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Envoy at 87.6% to American at 64.8%.

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 72.4% of the time; American Airlines manages 64.8%. Sample sizes sit next to every figure, because a two-point gap across 1,070 flights means less than a ten-point one.

SkyWest Airlines cancels 3.4% 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 254 flights.

The 8am–11am window is the strongest at 89.1% on time. The full set of windows spans 4 points.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 87.6% on time across 254 flights.

Envoy on DFW to COS did not run the same all year. Its best quarter was Jan–Mar 2026 at 95.3% on time and its weakest Jul–Sep 2025 at 82.1%, a swing of 13 points on roughly 64 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, Friday is the strongest day at 97.0% on time and Saturday the weakest at 78.2%. 19 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 42% of the 1,448 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
42%
National Airspace System
32%
Carrier
14%
Extreme weather
11%

Extreme weather accounts for 11% 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 1.8 times the usual weather exposure. The split is drawn from 1,448 reported delay minutes.

42% 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 1,448 reported delay minutes here, that single category outweighs weather by 4 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 sit at 1.57% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 3.6% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 592 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 86.7% on time across 254 flights, within about 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. 254 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 COS

Put together: treat all of this as provisional. 254 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 87.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 250 completed flights over 12 months sit behind that.
