Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on ORD to MLI sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 7 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 621 flights, with a median arrival 3 minutes early.
The national on-time rate over the same period is 77.6%, so Envoy on ORD to MLI runs 7 points behind the country as a whole. Across a thousand flights that is about 68 extra late arrivals.

These figures cover 621 flights between July 2025 and June 2026. Beyond the headline rate, 9.6% 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.
Carrier by carrier
Envoy against every carrier on ORD to MLI
Envoy flew 621 of the 2,191 flights on ORD to MLI, about 28% of it. Its 70.8% on time is 2 points better than the route as a whole, which runs 68.5%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Envoy at 70.8% to Republic at 44.4%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Envoy runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am191 flights77.8%
- 11am–2pm19 flights—
- 2pm–5pm24 flights—
- 5pm–8pm232 flights68.8%
- 8pm–5am155 flights61.5%
Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 61.5% on time, against 77.8% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 232 flights scheduled in it.
Across the year
Envoy on ORD to MLI through the year
July is the worst month at 47.0% on time, 41 points below September, the best at 87.7%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. June was the busiest month here, with 86 flights.
Across the week, Tuesday is the strongest day at 84.7% on time and Monday the weakest at 62.0%. 23 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Envoy runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 54% of the 9,792 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.
- 54%Late-arriving aircraft
- 20%National Airspace System
- 14%Carrier
- 11%Extreme weather
Extreme weather accounts for 11% 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 monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 1.8 times the usual weather exposure. The split is drawn from 9,792 reported delay minutes.
54% 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 9,792 reported delay minutes here, that single category outweighs weather by 5 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.
Cancellations run at 2.74%, against 1.81% nationally. That is roughly one flight in 40 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 stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.6% 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.
At 139 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 74.5% on time across 624 flights, 4 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.
One caution: this is a thin sample. 621 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 Envoy on ORD to MLI
Put together: treat all of this as provisional. 621 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 70.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 603 completed flights over 12 months sit behind that.
