Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on ORD to GRR carries a cancellation problem, not just a delay problem: 3.9% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four 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 967 flights. The strongest carrier on the route with a full sample, SkyWest Airlines, flew 881 at 71.8% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on ORD to GRR 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 ORD to GRR
Envoy flew 967 of the 4,077 flights on ORD to GRR, about 24% of it. Its 75.2% on time is 6 points better than the route as a whole, which runs 69.5%. Ranked by on-time rate it is first of six carriers on the route, where the range runs from Envoy at 75.2% to PSA at 0.0%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 71.8% of the time; American Airlines manages 58.7%. Sample sizes sit next to every figure, because a two-point gap across 478 flights means less than a ten-point one.

SkyWest Airlines cancels 4.1% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 20 points, against 13 points between the best and worst carrier.
- 5am–8am84 flights86.8%
- 8am–11am82 flights70.9%
- 11am–2pm321 flights80.1%
- 2pm–5pm251 flights70.2%
- 5pm–8pm70 flights79.4%
- 8pm–5am159 flights66.7%
Scale runs 60% to 90%.
Book the early departure. Flights leaving between 5am–8am arrive on time 86.8% of the time, against 66.7% for the overnight window. That is 20 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 321 flights scheduled in it.
Across the year
Envoy on ORD to GRR through the year
December is the weak month at 62.8% on time, against 88.4% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. April was the busiest month here, with 110 flights.
Across the week, Saturday is the strongest day at 79.5% on time and Wednesday the weakest at 68.3%, a spread of 11 points.
Arrival by arrival
How late Envoy on ORD to GRR runs when it is late

Share of 926 completed flights by arrival against schedule.
39 of 220 late departures made up the time and arrived on time, 18% of them. In the other direction, 49 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 GRR.
The worst days
Worst days for Envoy on ORD to GRR
The latest arrival of the period was on 15 May 2026, 5 hours 38 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.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 15 May 2026 | 5 hours 38 minutes | Late-arriving aircraft |
| 30 January 2026 | 4 hours 54 minutes | Extreme weather |
| 31 March 2026 | 4 hours 44 minutes | Late-arriving aircraft |
| 12 December 2025 | 4 hours 35 minutes | Late-arriving aircraft |
| 13 March 2026 | 3 hours 52 minutes | Late-arriving aircraft |
Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 55% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 19%National Airspace System
- 14%Extreme weather
- 12%Carrier
Extreme weather accounts for 14% 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 2.4 times the usual weather exposure. The split is drawn from 14,621 reported delay minutes.
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 4 to one.
Cancellations run at 3.93%, 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
9.5% 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 137 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 70.2% on time across 967 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 967 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 GRR
Put together: the delay figures matter less here than the 3.93% cancellation rate. A late arrival costs you about 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. 926 completed flights over 12 months sit behind that.
