Every carrier on DFW to COS, 1,934 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.

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 47% of the 796 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
47%
National Airspace System
33%
Carrier
16%
Extreme weather
4%

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 796 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 796 reported delay minutes.

33% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 259 minutes out of 796, against a national NAS share of 21%.

Cancellations sit at 1.50% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 2.5% land an hour or more behind schedule, against 8.3% 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.

The return leg runs 87.2% 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 DFW to COS

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 89.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 197 completed flights over 12 months sit behind that.
