Envoy on ORD to FSD 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 roughly 50 minutes behind schedule. That rests on 390 flights, with a median arrival 1 minute early.
The national on-time rate over the same period is 77.6%, so Envoy on ORD to FSD runs 5 points behind the country as a whole. Across a thousand flights that is about 51 extra late arrivals.

These figures cover 390 flights between July 2025 and June 2026. Beyond the headline rate, 8.3% 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 FSD
Envoy flew 390 of the 1,829 flights on ORD to FSD, about 21% of it. Its 72.5% on time is 9 points better than the route as a whole, which runs 63.3%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from PSA at 73.3% to United at 55.0%. Three 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 14 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–11am78 flights79.2%
- 11am–2pm98 flights65.6%
- 2pm–5pm20 flights—
- 5pm–8pm96 flights71.3%
- 8pm–5am98 flights75.3%
Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 65.6% on time against 79.2% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 98 flights scheduled in it.
Across the year
Envoy on ORD to FSD through the year
- Oct–Dec 202511 flights—
- Jan–Mar 2026210 flights69.8%
- Apr–Jun 2026169 flights76.5%
Scale runs 60% to 80%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 72.5% on time across 390 flights.
Split by quarter, Envoy on ORD to FSD logged 11 flights in Oct–Dec 2025, 210 flights in Jan–Mar 2026 and 169 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 72.5% annual figure is the one to use.
Across the week, Saturday is the strongest day at 80.0% on time and Friday the weakest at 63.6%. 16 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 47% of the 5,394 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.
- 47%Late-arriving aircraft
- 30%National Airspace System
- 15%Carrier
- 8%Extreme weather
47% 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 5,394 reported delay minutes here, that single category outweighs weather by 6 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 5,394 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 79.2% on time here.
Cancellations run at 3.85%, against 1.81% nationally. That is about one flight in 25 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
8.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 50 minutes, which a normal layover absorbs.
At 462 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 76.9% on time across 393 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. 390 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 FSD
Put together: the delay figures matter less here than the 3.85% cancellation rate. A late arrival costs you roughly 50 minutes; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 375 completed flights over 12 months sit behind that.
