Envoy on FSD to ORD lands a B−, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 393 flights, with a median arrival 6 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate Envoy on FSD to ORD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier

Envoy against every carrier on FSD to ORD

Envoy flew 393 of the 1,792 flights on FSD to ORD, about 22% of it. Its 76.9% on time is 8 points better than the route as a whole, which runs 68.9%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from United at 82.0% to SkyWest at 61.1%. 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 27 points, against half a point between the best and worst carrier.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.0% of the time, against 66.3% for the afternoon window. That is 27 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 115 flights scheduled in it.

Split by quarter, Envoy on FSD to ORD logged 12 flights in Oct–Dec 2025, 211 flights in Jan–Mar 2026 and 170 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 76.9% annual figure is the one to use.

Across the week, Saturday is the strongest day at 88.0% on time and Friday the weakest at 70.9%, a spread of 17 points.

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 48% of the 5,931 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
48%
National Airspace System
27%
Carrier
14%
Extreme weather
11%

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 1.9 times the usual weather exposure. The split is drawn from 5,931 reported delay minutes.

48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,931 reported delay minutes here, that single category outweighs weather by 4 to one.

Cancellations run at 3.82%, 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

9.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

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 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 72.5% on time across 390 flights, 4 points below 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. 393 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 FSD to ORD

Put together: the delay figures matter less here than the 3.82% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 377 completed flights over 12 months sit behind that.
