Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3976, 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 3976 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 260 flights, with a median arrival 13 minutes early.

Set against the rest of the country, MQ 3976's record is 13 points better than the US average of 77.6%. That gap is worth roughly 126 fewer late arrivals for every thousand flights.

These figures cover 260 flights between July 2025 and June 2026. The median arrival is 13 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 3976 flies

MQ 3976 flies SGF to DFW without a single fixed slot. Its most common scheduled departure was 06:00, used on 91 of 260 flights, with 07:08 (43 flights) and 05:32 (42 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 3976 runs level with that at 90.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

MQ 3976 next to SGF to DFW

Every carrier on SGF to DFW combined arrived on time 79.9% of the time across 3,085 flights, so MQ 3976 is 10 points ahead of it. Envoy flew 2,613 flights on the same city pair under all its flight numbers, including this one, and those ran 79.4% on time. Across its whole network Envoy Air managed 80.2%, which this flight beats by 10 points.

Across the year

MQ 3976 quarter by quarter

MQ 3976 did not run the same all year. Its best quarter was Oct–Dec 2025 at 95.4% on time and its weakest Jul–Sep 2025 at 80.4%, a swing of 15 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.

Jan–Mar 202690 flights95.4%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3976 did best on Thursday at 97.3% on time and worst on Saturday at 80.6%. 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 3976 runs late

One category carries most of the weight here. National Airspace System accounts for 46% of the 1,899 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.

National Airspace System
46%
Carrier
27%
Extreme weather
27%

Extreme weather accounts for 27% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.3 times the usual weather exposure. The split is drawn from 1,899 delay minutes reported on MQ 3976.

Cancellations sit at 1.54% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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 four other city pairs in the data, including SDF to ORD (36), DCA to ATL (35) and ATL to DCA (35), but none flew often enough under MQ 3976 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SGF to DFW only.

One caution: this is a thin sample. 260 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 3976

For a booking, read MQ 3976 as 90.2% on time with 1.54% cancelled over 260 flights. Those are rates from the past twelve months, not a forecast for any particular day.
