Historical statistics for September 2025 to August 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, 6 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 257 flights, with a median arrival 7 minutes early.
Set against the rest of the country, MQ 4034's record is 6 points better than the US average of 77.3%. That gap is worth roughly 61 fewer late arrivals for every thousand flights.

These figures cover 257 flights between September 2025 and August 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.

Across the year
MQ 4034 quarter by quarter
Quarter by quarter MQ 4034 held fairly steady: 88.3% in Oct–Dec 2025, 86.1% in Jan–Mar 2026, 80.0% in Apr–Jun 2026 and 80.3% in Jul–Sep 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202577 flights88.3%
- Jan–Mar 202637 flights86.1%
- Apr–Jun 202652 flights80.0%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 4034 did best on Monday at 89.2% on time and worst on Sunday at 75.7%. Each day rests on about 37 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

The worst days
Worst days for MQ 4034
The latest arrival of the period was on 12 July 2026, 3 hours 34 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 July 2026 | 3 hours 34 minutes | Late-arriving aircraft |
| 25 January 2026 | 3 hours 33 minutes | National Airspace System |
| 10 May 2026 | 2 hours 52 minutes | Late-arriving aircraft |
| 21 September 2025 | 2 hours 17 minutes | Late-arriving aircraft |
| 24 October 2025 | 2 hours | Extreme weather |
Delay causes
Why MQ 4034 runs late
Late-arriving aircraft accounts for 54% of the 2,602 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 22%National Airspace System
- 13%Carrier
- 11%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,602 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 2,602 delay minutes reported on MQ 4034.
Cancellations sit at 1.56% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.1% of arrivals land an hour or more late, close to the national 8.3%, so 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.
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. 257 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 83.4% on time with 1.56% cancelled over 257 flights. Those are rates from the past twelve months, not a forecast for any particular day.
