Every carrier on COS to DFW, 1,933 flights

These figures cover 200 flights between September 2025 and August 2026. The median arrival is 12 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.

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 200 flights.

8am–11am117 flights88.7%
11am–2pm41 flights82.5%
2pm–5pm36 flights88.6%
5pm–8pm6 flights—

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 82.5% on time against 88.7% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8am–11am window is the busiest, with 117 flights scheduled in it.

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 47% of the 1,771 delay minutes carriers reported here, and the remaining four split what is left.

Extreme weather accounts for 22% 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 3.7 times the usual weather exposure. The split is drawn from 1,771 reported delay minutes.

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,771 reported delay minutes here, that single category outweighs weather by 2 to one.

Cancellations sit at 1.50% against a national 1.89%, which is ordinary. Diversions add another 0.50%.

Connections and stage length

What a delay here costs

5.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

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.

The return leg runs 89.3% on time across 200 flights, within 2 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. 200 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 COS to DFW

Put together: treat all of this as provisional. 200 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 87.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 196 completed flights over 12 months sit behind that.
