Carrier by carrier
Envoy against every carrier on PIT to DCA
Envoy flew 170 of the 1,413 flights on PIT to DCA, about 12% of it. Its 51.2% on time is 16 points worse than the route as a whole, which runs 67.3%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Republic at 73.9% to Envoy at 51.2%. 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 73.9% of the time; PSA Airlines manages 64.7%. Sample sizes sit next to every figure, because a two-point gap across 371 flights means less than a ten-point one.

PSA Airlines cancels 7.3% 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 170 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 51.2% is the reliable figure here.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 51.2% on time across 170 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 57 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.

Share of 166 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 33 departures that left 15 minutes late or more, only 1 made it up before arrival. In the other direction, 49 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 DCA.
The worst days
Worst days for Envoy on PIT to DCA
The latest arrival of the period was on 12 February 2026, 3 hours 32 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across February, January and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 February 2026 | 3 hours 32 minutes | Carrier |
| 13 January 2026 | 3 hours 22 minutes | Late-arriving aircraft |
| 26 February 2026 | 2 hours 55 minutes | National Airspace System |
| 27 January 2026 | 2 hours 27 minutes | Late-arriving aircraft |

Delay causes
Why Envoy runs late on this route
National Airspace System accounts for 63% of the 4,206 delay minutes carriers reported here, and the remaining four split what is left.
- 63%National Airspace System
- 26%Late-arriving aircraft
- 10%Carrier
- 1%Extreme weather
63% 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 2,636 minutes out of 4,206, against a national NAS share of 21%. The split is drawn from 4,206 reported delay minutes.
Cancellations sit at 2.35% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
12.0% 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 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 87.3% on time across 170 flights, 36 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 36 points of difference.
One caution: this is a thin sample. 170 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. 170 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 51.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 166 completed flights over 12 months sit behind that.
