Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on ORD to PIA carries a cancellation problem, not just a delay problem: 4.7% 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 C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,001 flights, with a median arrival 4 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on ORD to PIA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on ORD to PIA, 2,213 flights
These figures cover 1,001 flights between September 2025 and August 2026. The median arrival is 4 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
Envoy against every carrier on ORD to PIA
Envoy flew 1,001 of the 2,213 flights on ORD to PIA, about 45% of it. Its 73.7% on time is 4 points better than the route as a whole, which runs 70.1%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Envoy at 73.7% to SkyWest at 67.2%.
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 14 points, against half a point between the best and worst carrier.
- 5am–8am9 flights—
- 8am–11am211 flights81.3%
- 11am–2pm86 flights82.6%
- 2pm–5pm74 flights79.5%
- 5pm–8pm280 flights68.5%
- 8pm–5am341 flights69.2%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 82.6% on time, ahead of 5pm–8pm at 68.5%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 8pm–5am window is the busiest, with 341 flights scheduled in it.
Across the year
Envoy on ORD to PIA through the year
December is the weak month at 54.8% on time, against 84.6% in May. 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. May was the busiest month here, with 93 flights.
Across the week, Tuesday is the strongest day at 77.3% on time and Thursday the weakest at 69.9%, a spread of 7 points.
Arrival by arrival
How late Envoy on ORD to PIA runs when it is late
Envoy on ORD to PIA often beats the schedule: 263 of 953 completed flights, 28%, arrived 15 minutes or more early. The 251 late arrivals split 99 under half an hour, 78 between 30 and 60 minutes, and 74 an hour or more.

Share of 953 completed flights by arrival against schedule.
43 of 246 late departures made up the time and arrived on time, 17% of them. In the other direction, 48 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 PIA.
The worst days
Worst days for Envoy on ORD to PIA
The latest arrival of the period was on 12 December 2025, 8 hours 6 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across December, August, July and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 December 2025 | 8 hours 6 minutes | Carrier |
| 13 August 2026 | 7 hours 48 minutes | Extreme weather |
| 4 July 2026 | 6 hours 1 minute | Late-arriving aircraft |
| 15 March 2026 | 5 hours 21 minutes | Late-arriving aircraft |
| 30 December 2025 | 5 hours 6 minutes | Extreme weather |
Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 52% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 17%National Airspace System
- 16%Carrier
- 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 14,378 reported delay minutes.
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 4.70%, against 1.89% nationally. That is about one flight in twenty 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
7.8% of arrivals land an hour or more late, close to the national 8.3%, so 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.
At 130 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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 77.2% on time across 1,001 flights, 4 points above 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 4 points of difference.
One caution: this is a thin sample. 1,001 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 PIA
Put together: the delay figures matter less here than the 4.70% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 953 completed flights over 12 months sit behind that.
