Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on ORD to DAY lands a B−, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 467 flights. The strongest carrier on the route with a full sample, SkyWest Airlines, flew 622 at 61.1% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on ORD to DAY 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 DAY
Envoy flew 467 of the 1,815 flights on ORD to DAY, about 26% of it. Its 76.1% on time is 10 points better than the route as a whole, which runs 66.2%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from United at 80.9% to PSA at 60.5%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: half a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

| PSA Airlines | 562 | 60.5% | 162 min | 5.52% | D− |
PSA Airlines cancels 5.5% 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 23 points, against half a point between the best and worst carrier.

- 8am–11am74 flights93.2%
- 11am–2pm108 flights74.0%

Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 93.2% of the time, against 70.6% for the overnight window. That is 23 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 160 flights scheduled in it.

Quarter by quarter Envoy on ORD to DAY held fairly steady: 76.1% in Oct–Dec 2025, 75.0% in Jan–Mar 2026, 77.4% in Apr–Jun 2026 and 73.6% in Jul–Sep 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
Across the week, Saturday is the strongest day at 80.0% on time and Sunday the weakest at 69.1%, a spread of 11 points.
Arrival by arrival
How late Envoy on ORD to DAY runs when it is late
Envoy on ORD to DAY often beats the schedule: 141 of 452 completed flights, 31%, arrived 15 minutes or more early. The 108 late arrivals split 31 under half an hour, 35 between 30 and 60 minutes, and 42 an hour or more.

Share of 452 completed flights by arrival against schedule.
21 of 105 late departures made up the time and arrived on time, 20% of them. In the other direction, 24 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 DAY.
The worst days
Worst days for Envoy on ORD to DAY
The latest arrival of the period was on 30 November 2025, 4 hours 56 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 November 2025 | 4 hours 56 minutes | Late-arriving aircraft |
| 13 August 2026 | 4 hours 32 minutes | Late-arriving aircraft |
| 2 April 2026 | 4 hours 14 minutes | Late-arriving aircraft |

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 56% of the 7,290 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 22%National Airspace System
- 11%Carrier
- 11%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,290 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 7,290 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 93.2% on time here.
Cancellations run at 3.21%, 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
9.3% 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 240 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 78.7% on time across 464 flights, within 3 points 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. 467 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 DAY
Put together: the delay figures matter less here than the 3.21% cancellation rate. A late arrival costs you about an hour; 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. 452 completed flights over 12 months sit behind that.
