Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on ORD to DTW carries a cancellation problem, not just a delay problem: 3.4% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 946 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 454 at 79.2% on time.
Republic Airways is the most reliable of the four carriers covered here at 79.2% on time across 454 flights.

These figures cover 946 flights between September 2025 and August 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
Envoy against every carrier on ORD to DTW
Envoy flew 946 of the 6,013 flights on ORD to DTW, about 16% of it. Its 78.2% on time is 7 points better than the route as a whole, which runs 71.1%. Ranked by on-time rate it is number two of seven carriers on the route, where the range runs from Republic at 79.2% to PSA at 60.0%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 79.2% of the time; SkyWest Airlines manages 64.6%. Sample sizes sit next to every figure, because a two-point gap across 2,563 flights means less than a ten-point one.

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 49% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 22%National Airspace System
- 18%Carrier
- 11%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 10,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 10,437 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.3% on time here.
Cancellations run at 3.38%, against 1.89% 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 stage length
What a delay here costs
6.8% 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 235 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 runs 79.2% on time across 946 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 946 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 DTW
Put together: the delay figures matter less here than the 3.38% cancellation rate. A late arrival costs you roughly 50 minutes; 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. 914 completed flights over 12 months sit behind that.
