Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3694, 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 3694 draws a C−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 305 flights, with a median arrival 3 minutes early.
The national on-time rate over the same period is 77.6%, so MQ 3694 runs 12 points behind the country as a whole. Across a thousand flights that is about 120 extra late arrivals.

These figures cover 305 flights between July 2025 and June 2026. Beyond the headline rate, 16.7% 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 3694 flies
MQ 3694 flies ORD to CMI without a single fixed slot. Its most common scheduled departure was 20:27, used on 37 of 305 flights, with 20:26 (36 flights) and 20:29 (33 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 20:2737 flights12.1%
- Departs 20:2636 flights11.8%
- Departs 20:2933 flights10.8%
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 20:27 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and MQ 3694 runs 5 points worse at 65.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
MQ 3694 quarter by quarter
MQ 3694 did not run the same all year. Its best quarter was Apr–Jun 2026 at 73.4% on time and its weakest Jan–Mar 2026 at 57.3%, a swing of 16 points on roughly 76 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 202572 flights67.1%
- Oct–Dec 202573 flights64.3%
- Jan–Mar 202676 flights57.3%
- Apr–Jun 202684 flights73.4%
Scale runs 50% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3694 did best on Saturday at 70.5% on time and worst on Thursday at 57.4%. Each day rests on about 44 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why MQ 3694 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 61% of the 7,203 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.
- 61%Late-arriving aircraft
- 17%National Airspace System
- 13%Carrier
- 8%Extreme weather
61% 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 7,203 reported delay minutes here, that single category outweighs weather by 8 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 7,203 delay minutes reported on MQ 3694.
Cancellations run at 3.61%, against 1.81% nationally. That is about 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.7% 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.
Every one of the 305 flights under MQ 3694 in the data flew ORD to CMI. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 305 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 3694
For a booking, the cancellation rate is the figure to plan around on MQ 3694: 3.61% of its 305 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.
