MQ 3624 lands a B, 5 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 close to two hours on average. That rests on 313 flights, with a median arrival 12 minutes early.
Set against the rest of the country, MQ 3624's record is 5 points better than the US average of 77.3%. That gap is worth roughly 51 fewer late arrivals for every thousand flights.

These figures cover 313 flights between September 2025 and August 2026. The median arrival is 12 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 08:14, used on 70 of 313 flights, with 07:00 (64 flights) and 07:15 (46 flights) next.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 08:14 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and MQ 3624 runs level with that at 82.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

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 63 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 3624 did best on Sunday at 88.4% on time and worst on Saturday at 70.5%. Each day rests on about 45 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late MQ 3624 runs when it is late
MQ 3624 often beats the schedule: 126 of 307 completed flights, 41%, arrived 15 minutes or more early. The 54 late arrivals split 16 under half an hour, 17 between 30 and 60 minutes, and 21 an hour or more.

Share of 307 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 34 departures that left 15 minutes late or more, only 4 made it up before arrival. In the other direction, 24 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DFW.
The worst days
Worst days for MQ 3624
The latest arrival of the period was on 10 July 2026, 14 hours 28 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. Three of the five worst days fell in June 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 10 July 2026 | 14 hours 28 minutes | Late-arriving aircraft |
| 4 June 2026 | 11 hours | Carrier |
| 19 June 2026 | 10 hours 6 minutes | National Airspace System |
| 22 June 2026 | 8 hours 39 minutes | Late-arriving aircraft |

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 5,911 reported delay minutes.
- 32%Carrier
- 30%Late-arriving aircraft
- 29%National Airspace System
- 9%Extreme weather
No single cause dominates. carrier at 32%, late-arriving aircraft at 30% and national airspace system at 29% split the 5,911 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around. The split is drawn from 5,911 delay minutes reported on MQ 3624.
Cancellations sit at 1.60% against a national 1.89%, which is ordinary. Diversions add another 0.32%.
Connections and routes
What a delay on this flight costs
6.8% 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 close to two hours, 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 82.4% on time with 1.60% cancelled over 313 flights. Those are rates from the past twelve months, not a forecast for any particular day.
