Every carrier on DFW to HSV, 2,080 flights
These figures cover 1,083 flights between September 2025 and August 2026. The median arrival is 9 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 HSV
Envoy flew 1,083 of the 2,080 flights on DFW to HSV, most of the route. Its 83.2% on time is 7 points better than the route as a whole, which runs 76.5%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from SkyWest at 85.9% to American at 44.8%. 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 matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against half a point between the best and worst carrier.
- 5am–8am166 flights89.6%
- 8am–11am186 flights89.1%
- 11am–2pm169 flights87.4%
- 2pm–5pm177 flights84.2%
- 5pm–8pm232 flights74.0%
- 8pm–5am153 flights77.3%
Scale runs 65% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 89.6% of the time, against 74.0% for the evening window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 232 flights scheduled in it.
Across the year
Envoy on DFW to HSV through the year
January is the weak month at 71.4% on time, against 94.3% in February. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 144 flights.
Across the week, Tuesday is the strongest day at 87.1% on time and Sunday the weakest at 77.8%, a spread of 9 points.

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 11,000 reported delay minutes.
- 37%Late-arriving aircraft
- 24%National Airspace System
- 23%Carrier
- 16%Extreme weather
- 0%Security
Extreme weather accounts for 16% 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 2.7 times the usual weather exposure. The split is drawn from 10,585 reported delay minutes.
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 2 to one.
Cancellations sit at 1.75% against a national 1.89%, which is ordinary. Diversions add another 0.18%.
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 about an hour, which a normal layover absorbs.
The 603 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 is a different operation and performs like one: it runs 80.2% on time across 1,081 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 1,083 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 HSV
Put together: treat all of this as provisional. 1,083 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 83.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,062 completed flights over 12 months sit behind that.
