Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.

Envoy on HSV to DFW lands a B, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 1,022 flights, with a median arrival 7 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate Envoy on HSV to DFW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on HSV to DFW, 2,055 flights

These figures cover 1,022 flights between July 2025 and June 2026. Beyond the headline rate, 8.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

Envoy against every carrier on HSV to DFW

Envoy flew 1,022 of the 2,055 flights on HSV to DFW, about 50% of it. Its 78.4% on time is 2 points better than the route as a whole, which runs 76.3%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Envoy at 78.4% to American at 73.3%. 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 13 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am154 flights85.0%
8am–11am229 flights81.6%
11am–2pm107 flights82.5%

5pm–8pm273 flights71.9%
8pm–5am—

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 85.0% of the time, against 71.9% for the evening window. That is 13 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 273 flights scheduled in it.

Across the year

Envoy on HSV to DFW through the year

Darker means more delays. Figures are on-time percentages.December best, January worst

January is the weak month at 72.2% on time, against 85.9% in December. 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 129 flights.

Across the week, Tuesday is the strongest day at 87.4% on time and Sunday the weakest at 69.5%. 18 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 44% of the 17,000 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
44%
Carrier
31%
National Airspace System
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 17,218 reported delay minutes.

44% 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 17,000 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 2.15% against a national 1.81%, which is ordinary. Diversions add another 0.59%.

Connections and stage length

What a delay here costs

8.2% 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 a little over 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. 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 is a different operation and performs like one: it runs 82.8% on time across 1,022 flights, 4 points above 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 4 points of difference.

One caution: this is a thin sample. 1,022 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 HSV to DFW

Put together: treat all of this as provisional. 1,022 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 78.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 994 completed flights over 12 months sit behind that.
