Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3624, 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 3624 lands a B, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 313 flights, with a median arrival 10 minutes early.

Set against the rest of the country, MQ 3624's record is 4 points better than the US average of 77.6%. That gap is worth roughly 42 fewer late arrivals for every thousand flights.

These figures cover 313 flights between July 2025 and June 2026. The median arrival is 10 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 3624 flies

MQ 3624 flies SGF to DFW without a single fixed slot. Its most common scheduled departure was 07:00, used on 64 of 313 flights, with 07:15 (46 flights) and 08:14 (40 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 3624 runs 8 points worse at 81.8%. 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 3624 next to SGF to DFW

Across the year

MQ 3624 quarter by quarter

MQ 3624 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.9% on time and its weakest Apr–Jun 2026 at 69.6%, a swing of 17 points on roughly 78 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 flights79.1%
Oct–Dec 202585 flights86.9%
Jan–Mar 202689 flights86.2%
Apr–Jun 202647 flights69.6%

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

By weekday, MQ 3624 did best on Friday at 91.3% on time and worst on Saturday at 70.5%. Each day rests on about 45 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3624 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,948 reported delay minutes.

National Airspace System
37%
Carrier
34%
Extreme weather
18%
Late-arriving aircraft
11%

Extreme weather accounts for 18% 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 2.9 times the usual weather exposure. The split is drawn from 4,948 delay minutes reported on MQ 3624.

Cancellations sit at 1.28% against a national 1.81%, which is ordinary. Diversions add another 0.32%.

Connections and routes

What a delay on this flight costs

6.5% 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 an hour and a half, which a normal layover absorbs.

The same number turns up on two other city pairs in the data, including LRD to DFW (1) and DFW to LRD (1), but none flew often enough under MQ 3624 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. 313 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 3624

For a booking, read MQ 3624 as 81.8% on time with 1.28% cancelled over 313 flights. Those are rates from the past twelve months, not a forecast for any particular day.
