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

Envoy on FSD 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 about an hour on average. That is a workable record, not a spotless one. That rests on 296 flights, with a median arrival 11 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate Envoy on FSD 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 FSD to DFW, 1,085 flights

These figures cover 296 flights between July 2025 and June 2026. The median arrival is 11 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 FSD to DFW

Envoy flew 296 of the 1,085 flights on FSD to DFW, about 27% of it. Its 80.8% on time is 7 points better than the route as a whole, which runs 74.2%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Envoy at 80.8% to SkyWest at 69.7%. One 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 296 flights.

5am–8am18 flights—
8am–11am—
11am–2pm104 flights75.5%
2pm–5pm—
5pm–8pm174 flights81.9%
8pm–5am—

Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 75.5% on time against 81.9% for 5pm–8pm. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 5pm–8pm window is the busiest, with 174 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 80.8% on time across 296 flights.

Envoy on FSD to DFW did not run the same all year. Its best quarter was Jan–Mar 2026 at 89.0% on time and its weakest Jul–Sep 2025 at 71.9%, a swing of 17 points on roughly 99 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Tuesday is the strongest day at 88.6% on time and Sunday the weakest at 70.0%. 19 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 56% of the 3,301 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
56%
National Airspace System
20%
Carrier
14%
Extreme weather
10%
Security
1%

56% 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 3,301 reported delay minutes here, that single category outweighs weather by 5 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 3,301 reported delay minutes.

Cancellations run at 2.70%, against 1.81% nationally. That is about 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

7.3% 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 about an hour, which a normal layover absorbs.

The 737 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 86.1% on time across 296 flights, 5 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 5 points of difference.

One caution: this is a thin sample. 296 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 FSD to DFW

Put together: treat all of this as provisional. 296 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 80.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 287 completed flights over 12 months sit behind that.
