Across the year
MQ 3626 quarter by quarter
MQ 3626 did not run the same all year. Its best quarter was Apr–Jun 2026 at 76.5% on time and its weakest Jul–Sep 2026 at 54.4%, a swing of 22 points on roughly 82 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.

- Oct–Dec 202583 flights66.3%
- Jan–Mar 202664 flights71.4%
- Apr–Jun 202690 flights76.5%

Scale runs 45% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3626 did best on Tuesday at 81.6% on time and worst on Thursday at 58.7%. Each day rests on about 47 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Arrival by arrival

Share of 315 completed flights by arrival against schedule.
17 of 96 late departures made up the time and arrived on time, 18% of them. In the other direction, 18 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 SGF.

Worst days for MQ 3626
The latest arrival of the period was on 9 November 2025, 4 hours 44 minutes behind schedule; most of its delay minutes were filed as extreme weather. On four of the five worst days the largest share was filed as a late-arriving aircraft.

| 26 January 2026 | 4 hours 2 minutes | Late-arriving aircraft |

Delay causes
Why MQ 3626 runs late
Late-arriving aircraft accounts for 63% of the 7,064 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Late-arriving aircraft
- 19%National Airspace System
- 11%Carrier
- 6%Extreme weather
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,064 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 7,064 delay minutes reported on MQ 3626.
Cancellations run at 3.07%, against 1.89% nationally. That is roughly one flight in 30 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
14.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The same number turns up on three other city pairs in the data, including SGF to ORD (76), DFW to SAT (2) and SAT to DFW (2), but none flew often enough under MQ 3626 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to SGF only.
One caution: this is a thin sample. 326 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 3626
For a booking, the cancellation rate is the figure to plan around on MQ 3626: 3.07% of its 326 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
