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

Envoy on HOU to DFW lands a B, 3 points 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 1,061 flights. The strongest carrier on the route with a full sample, PSA Airlines, flew 607 at 77.2% on time.

The US average over the same twelve months is 77.6%, so there is little to separate Envoy on HOU 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 HOU to DFW, 2,048 flights

These figures cover 1,061 flights between July 2025 and June 2026. The median arrival is 5 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 HOU to DFW

Envoy flew 1,061 of the 2,048 flights on HOU to DFW, most of the route. Its 80.9% on time is 3 points better than the route as a whole, which runs 77.9%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Envoy at 80.9% to SkyWest at 70.6%.

The choice of carrier is not cosmetic here. PSA Airlines arrives on time 77.2% of the time; SkyWest Airlines manages 70.6%. Sample sizes sit next to every figure, because a two-point gap across 380 flights means less than a ten-point one.

SkyWest Airlines cancels 6.8% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 26 points, against 7 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am178 flights89.8%
  • 8am–11am434 flights85.6%
  • 11am–2pm6 flights
  • 2pm–5pm257 flights75.0%
  • 5pm–8pm100 flights63.8%
  • 8pm–5am86 flights72.7%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 63.8% on time, against 89.8% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 434 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.March best, August worst

August is the worst month at 71.1% on time, 19 points below March, the best at 90.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. August was the busiest month here, with 162 flights.

Across the week, Tuesday is the strongest day at 86.2% on time and Wednesday the weakest at 77.1%. 9 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 49% of the 13,000 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
    49%
  • National Airspace System
    22%
  • Extreme weather
    16%
  • Carrier
    12%
  • Security
    0%

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 2.6 times the usual weather exposure. The split is drawn from 13,426 reported delay minutes.

49% 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 13,000 reported delay minutes here, that single category outweighs weather by 3 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 run at 2.73%, against 1.81% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and stage length

What a delay here costs

6.4% 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.

At 247 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.

The return leg runs 81.1% on time across 1,061 flights, within half a point 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. 1,061 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 HOU to DFW

Put together: treat all of this as provisional. 1,061 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 80.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,031 completed flights over 12 months sit behind that.
