Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3626, 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 3626 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 320 flights, with a median arrival 7 minutes early.

The national on-time rate over the same period is 77.6%, so MQ 3626 runs 5 points behind the country as a whole. Across a thousand flights that is about 51 extra late arrivals.

These figures cover 320 flights between July 2025 and June 2026. Beyond the headline rate, 14.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When MQ 3626 flies

MQ 3626 flies ORD to SGF without a single fixed slot. Its most common scheduled departure was 17:18, used on 39 of 320 flights, with 19:10 (32 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 17:18 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and MQ 3626 runs 4 points better at 72.5%. 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 3626 next to ORD to SGF

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 Oct–Dec 2025 at 66.3%, a swing of 10 points on roughly 80 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 202664 flights71.4%

Scale runs 60% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3626 did best on Tuesday at 84.6% on time and worst on Friday at 66.7%. Each day rests on about 46 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3626 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 65% of the 6,664 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.

Extreme weather

Carrier
8%

65% 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 6,664 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 6,664 delay minutes reported on MQ 3626.

Cancellations sit at 1.88% against a national 1.81%, which is ordinary. Diversions add another 0.31%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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 (41), SAT to DFW (2) and DFW to SAT (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. 320 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, MQ 3626 is a flight to put a long connection behind. 14.7% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
