Carrier by carrier
Envoy against every carrier on PIT to ORD
Envoy flew 138 of the 4,031 flights on PIT to ORD, about 3% of it. Its 74.8% on time is 2 points worse than the route as a whole, which runs 77.1%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from Republic at 83.0% to American at 66.4%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 83.0% of the time; American Airlines manages 66.4%. Sample sizes sit next to every figure, because a two-point gap across 619 flights means less than a ten-point one.

American Airlines cancels 3.1% 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 138 flights.
- 5am–8am—
- 8am–11am—
- 11am–2pm43 flights73.8%
- 2pm–5pm52 flights78.8%
- 5pm–8pm31 flights—
- 8pm–5am12 flights—
Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 73.8% on time against 78.8% for 2pm–5pm. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 2pm–5pm window is the busiest, with 52 flights scheduled in it.

Share of 135 completed flights by arrival against schedule.
6 of 32 late departures made up the time and arrived on time, 19% of them. In the other direction, 8 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 latest arrival of the period was on 16 January 2026, 25 hours 28 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Four of the five worst days fell in January 2026.
| Date | Arrived late by | Largest filed cause |

Delay causes
Why Envoy runs late on this route
Carrier accounts for 47% of the 3,296 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Carrier
- 36%Late-arriving aircraft
- 13%National Airspace System
- 3%Security
- 1%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,296 reported delay minutes here, that single category outweighs weather by 28 to one. The split is drawn from 3,296 reported delay minutes.
The largest share of delay minutes, 47%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,536 of the 3,296 delay minutes reported here.
Cancellations sit at 2.17% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
8.1% 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 an hour and a half, which a normal layover absorbs.
At 413 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 2pm–5pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 80.0% on time across 138 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 138 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 PIT to ORD
Put together: treat all of this as provisional. 138 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 74.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 135 completed flights over 12 months sit behind that.
