Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4034, 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 4034 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 about an hour on average. That is a workable record, not a spotless one. That rests on 258 flights, with a median arrival 6 minutes early.

These figures cover 258 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 4034 flies
MQ 4034 flies DFW to MLI without a single fixed slot. Its most common scheduled departure was 21:00, used on 60 of 258 flights, with 21:22 (39 flights) and 19:57 (34 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

- Departs 19:5734 flights13.2%
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 21:00 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and MQ 4034 runs 11 points better at 81.4%. 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 4034 next to DFW to MLI
Every carrier on DFW to MLI combined arrived on time 82.3% of the time across 981 flights, so MQ 4034 is about level with it. Envoy flew 605 flights on the same city pair under all its flight numbers, including this one, and those ran 85.3% on time. Across its whole network Envoy Air managed 80.2%, close to this flight's figure.

Across the year
MQ 4034 quarter by quarter
MQ 4034 did not run the same all year. Its best quarter was Oct–Dec 2025 at 88.3% on time and its weakest Jul–Sep 2025 at 74.4%, a swing of 14 points on roughly 65 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 202592 flights74.4%
- Oct–Dec 202577 flights88.3%
- Jan–Mar 202637 flights86.1%
- Apr–Jun 202652 flights80.0%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 4034 did best on Monday at 91.7% on time and worst on Sunday at 70.3%. Each day rests on about 37 flights, so a gap of 21 points is worth noticing but could still narrow in another year.
Delay causes
Why MQ 4034 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 56% of the 2,788 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.
- 56%Late-arriving aircraft
- 25%National Airspace System
- 11%Extreme weather
- 8%Carrier
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 2,788 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 2,788 delay minutes reported on MQ 4034.
Cancellations sit at 1.94% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.5% 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 691 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 same number turns up on one other city pair in the data, including CMH to MIA (18), but none flew often enough under MQ 4034 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to MLI only.
One caution: this is a thin sample. 258 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 4034
For a booking, read MQ 4034 as 81.4% on time with 1.94% cancelled over 258 flights. Those are rates from the past twelve months, not a forecast for any particular day.
