Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on ORD to AVP sits in the middle of the pack with a B−. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 662 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Envoy on ORD to AVP from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 662 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Envoy against every carrier on ORD to AVP
Envoy flew 662 of the 842 flights on ORD to AVP, most of the route. Its 75.6% on time is 3 points better than the route as a whole, which runs 72.9%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Envoy at 75.6% to SkyWest at 63.1%. One 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 11 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am—
- 11am–2pm61 flights77.0%
- 2pm–5pm248 flights73.6%
- 5pm–8pm119 flights69.6%
- 8pm–5am234 flights80.7%
Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
The overnight block holds up unusually well at 80.7% on time across 234 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 2pm–5pm window is the busiest, with 248 flights scheduled in it.
Across the year
Envoy on ORD to AVP through the year
January is the weak month at 55.9% on time, against 87.5% in August. 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. March was the busiest month here, with 62 flights.
Across the week, Saturday is the strongest day at 80.0% on time and Sunday the weakest at 71.6%. 8 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Envoy runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 9,709 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

- 17%Carrier
- 16%National Airspace System
- 15%Extreme weather

Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 9,709 reported delay minutes.
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 9,709 reported delay minutes here, that single category outweighs weather by 3 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit.
Cancellations run at 3.32%, against 1.81% 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
8.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 632 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg runs 75.7% on time across 662 flights, within half 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. 662 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 AVP
Put together: the delay figures matter less here than the 3.32% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 8pm–5am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 640 completed flights over 12 months sit behind that.
