Flights: 256
Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3440, check with Envoy Air. Envoy Air flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

MQ 3440 lands a B−, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 256 flights, with a median arrival 6 minutes early.

These figures cover 256 flights between July 2025 and June 2026. The median arrival is 6 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.

Schedule

When MQ 3440 flies

MQ 3440 flies DFW to COU without a single fixed slot. Its most common scheduled departure was 21:11, used on 44 of 256 flights, with 20:54 (37 flights) and 21:15 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 21:11 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and MQ 3440 runs 6 points better at 76.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

MQ 3440 next to DFW to COU

Every carrier on DFW to COU combined arrived on time 81.6% of the time across 1,221 flights, so MQ 3440 is 5 points behind it. Envoy flew 1,172 flights on the same city pair under all its flight numbers, including this one, and those ran 82.0% on time. Across its whole network Envoy Air managed 80.2%, which this flight trails by 4 points.

Across the year

MQ 3440 quarter by quarter

MQ 3440 did not run the same all year. Its best quarter was Jan–Mar 2026 at 83.7% on time and its weakest Apr–Jun 2026 at 66.0%, a swing of 18 points on roughly 85 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.

Jul–Sep 202528 flights—
Oct–Dec 202588 flights76.2%
Jan–Mar 202690 flights83.7%

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3440 did best on Tuesday at 82.9% on time and worst on Friday at 65.6%. Each day rests on about 37 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3440 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 2,862 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.

Extreme weather
10%

46% 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 2,862 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 2,862 delay minutes reported on MQ 3440.

Cancellations run at 3.91%, 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 routes

What a delay on this flight costs

6.6% 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 50 minutes, which a normal layover absorbs.

The same number turns up on four other city pairs in the data, including PHX to SEA (41), SEA to PHX (41) and ATW to CLT (2), but none flew often enough under MQ 3440 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to COU only.

One caution: this is a thin sample. 256 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 MQ 3440

For a booking, the cancellation rate is the figure to plan around on MQ 3440: 3.91% of its 256 scheduled flights did not operate. A late arrival costs about 50 minutes, but a cancellation costs the day, so leave a later option open.
