Envoy on PIT to DCA earns a D, which is as low as this site's scale goes for a reason. Only 56.2% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. Late arrivals average roughly 50 minutes. Treat any tight connection here as a coin flip. That rests on 196 flights, with a median arrival 9 minutes late.

These figures cover 196 flights between July 2025 and June 2026. Beyond the headline rate, 10.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Envoy against every carrier on PIT to DCA
Envoy flew 196 of the 1,431 flights on PIT to DCA, about 14% of it. Its 56.2% on time is 13 points worse than the route as a whole, which runs 69.0%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Republic at 75.8% to Envoy at 56.2%. 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 PIT to DCA record by time of day without the percentages moving on noise. The headline rate of 56.2% is the reliable figure here.
Across the year
Envoy on PIT to DCA through the year
- Jul–Sep 202526 flights—
- Oct–Dec 202543 flights35.7%
- Jan–Mar 202678 flights49.3%
- Apr–Jun 202649 flights67.3%
Scale runs 25% to 75%. 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 56.2% on time across 196 flights.
Envoy on PIT to DCA did not run the same all year. Its best quarter was Apr–Jun 2026 at 67.3% on time and its weakest Oct–Dec 2025 at 35.7%, a swing of 32 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 73.3% on time and Wednesday the weakest at 46.9%. 26 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. National Airspace System accounts for 62% of the 4,301 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.
- 62%National Airspace System
- 27%Late-arriving aircraft
- 10%Carrier
- 1%Extreme weather
62% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,654 minutes out of 4,301, against a national NAS share of 21%. The split is drawn from 4,301 reported delay minutes.
Cancellations sit at 2.04% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
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 88.0% on time across 196 flights, 32 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 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 PIT to DCA
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 56.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 192 completed flights over 12 months sit behind that.
