Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4279, 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 4279 lands a B, 2 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 roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 266 flights, with a median arrival 7 minutes early.

These figures cover 266 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.

Schedule

When MQ 4279 flies

MQ 4279 flies DFW to MAF without a single fixed slot. Its most common scheduled departure was 18:38, used on 42 of 266 flights, with 18:45 (41 flights) and 18:37 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 18:38 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and MQ 4279 runs 11 points better at 79.5%. 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 4279 next to DFW to MAF

Every carrier on DFW to MAF combined arrived on time 80.4% of the time across 2,934 flights, so MQ 4279 is about level with it. Envoy flew 1,769 flights on the same city pair under all its flight numbers, including this one, and those ran 82.2% on time. Across its whole network Envoy Air managed 80.2%, close to this flight's figure.

Across the year

MQ 4279 quarter by quarter

MQ 4279 did not run the same all year. Its best quarter was Jan–Mar 2026 at 92.1% on time and its weakest Jul–Sep 2025 at 64.4%, a swing of 28 points on roughly 89 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.

By weekday, MQ 4279 did best on Wednesday at 89.7% on time and worst on Sunday at 72.2%. Each day rests on about 38 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 4279 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 2,288 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.

51%
National Airspace System
24%
Carrier
18%
Extreme weather
7%

51% 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 2,288 reported delay minutes here, that single category outweighs weather by 7 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 2,288 delay minutes reported on MQ 4279.

Cancellations run at 2.63%, 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 routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.9% 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 same number turns up on two other city pairs in the data, including MAF to DFW (136) and MEM to ORD (40), but none flew often enough under MQ 4279 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to MAF only.

One caution: this is a thin sample. 266 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 4279

For a booking, the cancellation rate is the figure to plan around on MQ 4279: 2.63% of its 266 scheduled flights did not operate. A late arrival costs roughly 45 minutes, but a cancellation costs the day, so leave a later option open.
