Carrier by carrier

Envoy against every carrier on ORD to FSD

Envoy flew 390 of the 1,790 flights on ORD to FSD, about 22% of it. Its 72.5% on time is 9 points better than the route as a whole, which runs 63.5%. 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 59.1%. 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.

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

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%, a spread of 16 points.

Share of 375 completed flights by arrival against schedule.

14 of 83 late departures made up the time and arrived on time, 17% of them. In the other direction, 34 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 FSD.

The worst days

Worst days for Envoy on ORD to FSD

The latest arrival of the period was on 14 April 2026, 5 hours 7 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 47% of the 5,394 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
47%
National Airspace System
30%
Carrier
15%
Extreme weather
8%

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,394 reported delay minutes here, that single category outweighs weather by 6 to one. 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 1.89% 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 8.3%, so 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.
