Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.

Envoy on PIT to ORD lands a B, level with the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 190 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 1,629 at 84.2% on time.

Republic Airways is the most reliable of the three carriers covered here at 84.2% on time across 1,629 flights.

Every carrier on PIT to ORD, 3,950 flights

These figures cover 190 flights between July 2025 and June 2026. The median arrival is 9 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 PIT to ORD

Envoy flew 190 of the 3,950 flights on PIT to ORD, about 5% of it. Its 78.3% on time is about level with the route as a whole at 78.6%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from Republic at 84.2% to SkyWest at 65.1%. 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 84.2% of the time; American Airlines manages 69.9%. Sample sizes sit next to every figure, because a two-point gap across 604 flights means less than a ten-point one.

The spread between Republic and American is 14 points, wide enough that it should decide the booking. On a hundred trips that is 14 more arrivals inside the on-time window.

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 190 flights.

5am–8am1 flights—
8am–11am1 flights—
11am–2pm45 flights75.0%
2pm–5pm78 flights80.5%
5pm–8pm53 flights79.6%
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 75.0% on time against 80.5% 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 78 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 78.3% on time across 190 flights.

Quarter by quarter Envoy on PIT to ORD held fairly steady: 83.8% in Jul–Sep 2025, 77.8% in Oct–Dec 2025 and 74.0% in Jan–Mar 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Thursday is the strongest day at 96.9% on time and Wednesday the weakest at 71.0%. 26 points is a smaller lever than departure hour, but it is free.

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 4,195 reported delay minutes.

Carrier
38%
Late-arriving aircraft
31%
National Airspace System
21%
Extreme weather
7%
Security
3%

The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,594 of the 4,195 delay minutes reported here. The split is drawn from 4,195 reported delay minutes.

Cancellations run at 2.63%, against 1.81% nationally. That is about one flight in 40 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

7.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, 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 83.2% on time across 189 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. 190 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. 190 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 78.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 184 completed flights over 12 months sit behind that.
