Envoy on PIA to ORD carries a cancellation problem, not just a delay problem: 4.6% 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 1,001 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on PIA to ORD 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 PIA to ORD
Envoy flew 1,001 of the 2,214 flights on PIA to ORD, about 45% of it. Its 77.2% on time is 7 points better than the route as a whole, which runs 70.5%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Envoy at 77.2% to SkyWest at 65.0%.
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 26 points, against half a point between the best and worst carrier.
- 5am–8am361 flights85.6%
- 8am–11am209 flights86.1%
- 11am–2pm87 flights75.9%
- 2pm–5pm14 flights—
- 5pm–8pm280 flights59.9%
- 8pm–5am50 flights68.2%
Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 59.9% on time, against 86.1% for the 8am–11am 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 361 flights scheduled in it.
Across the year
Envoy on PIA to ORD through the year
December is the weak month at 63.0% on time, against 91.6% 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. May was the busiest month here, with 93 flights.
Across the week, Wednesday is the strongest day at 81.2% on time and Sunday the weakest at 70.5%, a spread of 11 points.
Arrival by arrival
How late Envoy on PIA to ORD runs when it is late
Envoy on PIA to ORD often beats the schedule: 387 of 955 completed flights, 41%, arrived 15 minutes or more early. The 218 late arrivals split 72 under half an hour, 60 between 30 and 60 minutes, and 86 an hour or more.

Share of 955 completed flights by arrival against schedule.
25 of 176 late departures made up the time and arrived on time, 14% of them. In the other direction, 67 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 ORD.
The worst days
Worst days for Envoy on PIA to ORD
The latest arrival of the period was on 3 August 2026, 28 hours 23 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 3 August 2026 | 28 hours 23 minutes | Carrier |
| 2 August 2026 | 18 hours 40 minutes | Late-arriving aircraft |
| 31 July 2026 | 11 hours 53 minutes | Carrier |
| 24 October 2025 | 7 hours 49 minutes | Carrier |
| 11 December 2025 | 5 hours 34 minutes | Extreme weather |
Delay causes
Why Envoy runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 18,000 reported delay minutes.
- 35%Late-arriving aircraft
- 34%Carrier
- 26%National Airspace System
- 6%Extreme weather
- 0%Security
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 18,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 17,966 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 86.1% on time here.
Cancellations run at 4.60%, against 1.89% nationally. That is roughly 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
9.0% 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 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 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 73.7% on time across 1,001 flights, 4 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 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 PIA to ORD
Put together: the delay figures matter less here than the 4.60% cancellation rate. A late arrival costs you an hour and a half; 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. 955 completed flights over 12 months sit behind that.
