Envoy on CHA to DFW earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 236 flights, with a median arrival 10 minutes early.

Set against the rest of the country, Envoy's CHA to DFW record is 7 points better than the US average of 77.6%. That gap is worth roughly 67 fewer late arrivals for every thousand flights.

Every carrier on CHA to DFW, 1,640 flights

These figures cover 236 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 CHA to DFW

Envoy flew 236 of the 1,640 flights on CHA to DFW, about 14% of it. Its 84.3% on time is 6 points better than the route as a whole, which runs 78.6%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Envoy at 84.3% to American at 62.9%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 236 flights.

5am–8am38 flights91.9%
8am–11am17 flights—
11am–2pm127 flights83.6%
2pm–5pm47 flights83.0%
5pm–8pm7 flights—
8pm–5am—

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

Book the early departure. Flights leaving between 5am–8am arrive on time 91.9% of the time, against 83.0% for the afternoon window. That is 9 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 127 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 84.3% on time across 236 flights.

Quarter by quarter Envoy on CHA to DFW held fairly steady: 86.6% in Jul–Sep 2025, 85.1% in Jan–Mar 2026 and 78.8% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Tuesday is the strongest day at 92.3% on time and Sunday the weakest at 78.1%. 14 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Envoy runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,396 reported delay minutes.

Extreme weather
36%
Late-arriving aircraft
33%
Carrier
24%
National Airspace System
7%
Security
0%

Extreme weather accounts for 36% 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 5.8 times the usual weather exposure. The split is drawn from 3,396 reported delay minutes.

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.9% on time here.

Cancellations sit at 2.12% against a national 1.81%, which is ordinary. Diversions add another 0.85%.

Connections and stage length

What a delay here costs

6.6% 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 an hour and a half, which a normal layover absorbs.

The 695 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 82.6% on time across 235 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. 236 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 CHA to DFW

Put together: treat all of this as provisional. 236 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 84.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 229 completed flights over 12 months sit behind that.
