Envoy on DCA to PIT earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 196 flights, with a median arrival 11 minutes early.

Set against the rest of the country, Envoy's DCA to PIT record is 10 points better than the US average of 77.6%. That gap is worth roughly 104 fewer late arrivals for every thousand flights.

These figures cover 196 flights between July 2025 and June 2026. The median arrival is 11 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 DCA to PIT

Envoy flew 196 of the 1,431 flights on DCA to PIT, about 14% of it. Its 88.0% on time is 13 points better than the route as a whole, which runs 75.2%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Envoy at 88.0% to American at 65.6%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

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 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 196 flights.

There are not enough flights in each departure window to split Envoy's DCA to PIT record by time of day without the percentages moving on noise. The headline rate of 88.0% is the reliable figure here.

Across the year

Envoy on DCA to PIT through the year

Jul–Sep 202526 flights—
Oct–Dec 202543 flights92.9%
Jan–Mar 202678 flights77.0%
Apr–Jun 202649 flights98.0%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 88.0% on time across 196 flights.

Envoy on DCA to PIT did not run the same all year. Its best quarter was Apr–Jun 2026 at 98.0% on time and its weakest Jan–Mar 2026 at 77.0%, a swing of 21 points on roughly 65 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Monday is the strongest day at 90.0% on time and Wednesday the weakest at 84.4%. 6 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Envoy runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 991 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 991 reported delay minutes here, that single category outweighs weather by 32 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 991 reported delay minutes.

The largest share of delay minutes, 35%, 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 344 of the 991 delay minutes reported here.

Cancellations run at 2.55%, 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

Badly late arrivals are rare here: only 3.1% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 204 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 56.2% on time across 196 flights, 32 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 32 points of difference.

One caution: this is a thin sample. 196 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 DCA to PIT

Put together: treat all of this as provisional. 196 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 88.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 191 completed flights over 12 months sit behind that.
