Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on ATW to ORD carries a cancellation problem, not just a delay problem: 3.2% of scheduled flights never operate, against 1.8% 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 1,177 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Envoy on ATW to ORD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 1,177 flights between July 2025 and June 2026. Beyond the headline rate, 9.7% 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 ATW to ORD
Envoy flew 1,177 of the 2,515 flights on ATW to ORD, about 47% of it. Its 76.9% on time is 7 points better than the route as a whole, which runs 70.0%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Envoy at 76.9% to SkyWest at 63.7%.
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.

| Envoy Air (this page) | 1,177 | 76.9% | 72 min | 3.23% | B− |
| SkyWest Airlines | 1,338 | 63.7% | 93 min | 5.68% | D− |
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 23 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–8am355 flights86.9%
- 8am–11am248 flights80.2%
- 11am–2pm174 flights77.8%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 63.8% on time, against 86.9% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 355 flights scheduled in it.
Across the year
Envoy on ATW to ORD through the year
Delays peak in October, when the on-time rate falls to 68.1%. June is the strongest month at 88.3%. Moving a flexible trip across that boundary buys 20 points. March was the busiest month here, with 115 flights.
Across the week, Saturday is the strongest day at 83.0% on time and Sunday the weakest at 72.4%. 11 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 48% of the 19,000 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.
- 48%Late-arriving aircraft
- 36%National Airspace System
- 13%Carrier
- 4%Extreme weather
48% 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 19,000 reported delay minutes here, that single category outweighs weather by 12 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. The split is drawn from 18,952 reported delay minutes.
36% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 6,825 minutes out of 19,000, against a national NAS share of 21%.
Cancellations run at 3.23%, 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 160 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 74.8% on time across 1,177 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,177 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking Envoy on ATW to ORD
Put together: the delay figures matter less here than the 3.23% 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. 1,138 completed flights over 12 months sit behind that.
