Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.

Envoy on DTW to ORD carries a cancellation problem, not just a delay problem: 3.5% 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 453 at 81.8% on time.

Republic Airways is the most reliable of the four carriers covered here at 81.8% on time across 453 flights.

Carrier by carrier

Envoy against every carrier on DTW to ORD

Envoy flew 946 of the 6,014 flights on DTW to ORD, about 16% of it. Its 79.2% on time is 7 points better than the route as a whole, which runs 72.2%. Ranked by on-time rate it is number three of eight carriers on the route, where the range runs from American at 90.2% to Spirit at 0.0%. Three 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 81.8% of the time; SkyWest Airlines manages 68.5%. Sample sizes sit next to every figure, because a two-point gap across 2,563 flights means less than a ten-point one.

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 21 points, against 13 points between the best and worst carrier.

  • 8am–11am197 flights89.8%

Scale runs 60% to 95%.

Book the morning departure. Flights leaving between 8am–11am arrive on time 89.8% of the time, against 69.3% for the overnight window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 312 flights scheduled in it.

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 42% of the 17,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    42%
  • Carrier
    24%
  • National Airspace System
    18%
  • Extreme weather
    16%

Extreme weather accounts for 16% 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 2.7 times the usual weather exposure. The split is drawn from 16,810 reported delay minutes.

42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 17,000 reported delay minutes here, that single category outweighs weather by 3 to one.

Cancellations run at 3.49%, 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

9.5% 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 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 8am–11am window matters as much as it does.

The return leg runs 78.2% 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 DTW to ORD

Put together: the delay figures matter less here than the 3.49% cancellation rate. A late arrival costs you an hour and a half; 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. 913 completed flights over 12 months sit behind that.
