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

Envoy on DFW to HOU lands a B, 4 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 roughly 55 minutes 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, SkyWest Airlines, flew 380 at 73.7% on time.

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

Every carrier on DFW to HOU, 2,048 flights

These figures cover 1,061 flights between July 2025 and June 2026. The median arrival is 8 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 HOU

Envoy flew 1,061 of the 2,048 flights on DFW to HOU, most of the route. Its 81.1% on time is 4 points better than the route as a whole, which runs 76.9%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Envoy at 81.1% to PSA at 71.4%.

The two carriers here are closely matched: 2 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

On-time performance by carrier on DFW to HOU
Airline	Flights	On time	Avg delay	Cancelled	Grade
Envoy Air (this page)	1,061	81.1%	53 min	2.83%	B
SkyWest Airlines	380	73.7%	62 min	5.00%	C−
PSA Airlines	607	71.4%	96 min	5.11%	C−

PSA Airlines cancels 5.1% 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 25 points, against 2 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am162 flights89.4%
8am–11am271 flights89.4%
11am–2pm126 flights88.7%
2pm–5pm238 flights72.9%
5pm–8pm132 flights64.2%
8pm–5am132 flights77.3%

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

The 5pm–8pm window is where this operation falls apart: 64.2% on time, against 89.4% 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 271 flights scheduled in it.

Across the year

Envoy on DFW to HOU through the year

Darker means more delays. Figures are on-time percentages.November best, June worst

June is the worst month at 68.2% on time, 23 points below November, the best at 91.4%. 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, Thursday is the strongest day at 85.4% on time and Sunday the weakest at 76.5%. 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 48% of the 10,000 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.

Security
1%

48% 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 10,000 reported delay minutes here, that single category outweighs weather by 6 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. The split is drawn from 10,350 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 89.4% on time here.

Cancellations run at 2.83%, 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

Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.1% 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.

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 80.9% 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 DFW to HOU

Put together: the delay figures matter less here than the 2.83% cancellation rate. A late arrival costs you roughly 55 minutes; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 1,028 completed flights over 12 months sit behind that.
