Envoy on DFW to MOB lands a B−, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average.

Set against the rest of the country, Envoy's DFW to MOB record is 5 points better than the US average of 77.6%. That gap is worth roughly 46 fewer late arrivals for every thousand flights.

Every carrier on DFW to MOB, 1,161 flights
These figures cover 661 flights between July 2025 and June 2026. The median arrival is 7 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 MOB
Envoy flew 661 of the 1,161 flights on DFW to MOB, most of the route. Its 82.2% on time is 2 points better than the route as a whole, which runs 80.3%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Envoy at 82.2% to PSA at 77.7%.
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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Envoy Air (this page) | 661 | 82.2% | 49 min | 4.24% | B− |
| PSA Airlines | 500 | 77.7% | 90 min | 4.00% | B− |
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 19 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–8am—
- 8am–11am143 flights85.4%
- 11am–2pm93 flights93.3%
- 2pm–5pm176 flights75.0%
- 5pm–8pm132 flights74.6%
- 8pm–5am117 flights89.0%
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 93.3% on time, ahead of 5pm–8pm at 74.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 2pm–5pm window is the busiest, with 176 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 82.2% on time across 661 flights.
Envoy on DFW to MOB did not run the same all year. Its best quarter was Jan–Mar 2026 at 88.1% on time and its weakest Jul–Sep 2025 at 72.4%, a swing of 16 points on roughly 165 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, Monday is the strongest day at 84.4% on time and Sunday the weakest at 78.9%. 6 points is a smaller lever than departure hour, but it is free.
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 5,498 reported delay minutes.
- 40%Late-arriving aircraft
- 35%National Airspace System
- 18%Carrier
- 8%Extreme weather
40% 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 5,498 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 5,498 reported delay minutes.
35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,925 minutes out of 5,498, against a national NAS share of 21%.
Cancellations run at 4.24%, against 1.81% nationally. That is about one flight in 25 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 4.1% 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.
The 539 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 runs 83.1% on time across 661 flights, within about 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. 661 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 MOB
Put together: the delay figures matter less here than the 4.24% cancellation rate. A late arrival costs you about 50 minutes; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 630 completed flights over 12 months sit behind that.
