Republic on PIT to DCA sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.3%. The late ones land roughly 55 minutes behind schedule. That rests on 749 flights, with a median arrival 2 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate Republic on PIT to DCA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 749 flights between September 2025 and August 2026. The median arrival is 2 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

Republic against every carrier on PIT to DCA

Republic flew 749 of the 1,413 flights on PIT to DCA, most of the route. Its 73.9% on time is 7 points better than the route as a whole, which runs 67.3%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Republic at 73.9% to Envoy at 51.2%. 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 Republic runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 28 points, against half a point between the best and worst carrier.

5am–8am176 flights87.3%
8am–11am277 flights74.4%
11am–2pm199 flights68.6%

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 59.0% on time, against 87.3% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 277 flights scheduled in it.

Across the year

Republic on PIT to DCA through the year

Darker means more delays. Figures are on-time percentages.September best, November worst

September is the best month on the calendar at 89.2% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. January was the busiest month here, with 85 flights.

Across the week, Saturday is the strongest day at 82.4% on time and Thursday the weakest at 65.2%, a spread of 17 points.

Arrival by arrival

How late Republic on PIT to DCA runs when it is late

Share of 732 completed flights by arrival against schedule.

12 of 90 late departures made up the time and arrived on time, 13% of them. In the other direction, 113 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.

Delay causes

Why Republic runs late on this route

National Airspace System accounts for 62% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System
62%
Late-arriving aircraft
29%
Carrier
9%
Extreme weather
1%

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 6,279 minutes out of 10,000, against a national NAS share of 21%. The split is drawn from 10,161 reported delay minutes.

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 87.3% on time here.

Cancellations sit at 2.14% against a national 1.89%, which is ordinary. Diversions add another 0.13%.

Connections and stage length

What a delay here costs

7.2% 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 roughly 55 minutes, which a normal layover absorbs.

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 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 70.9% on time across 749 flights, 3 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 3 points of difference.

One caution: this is a thin sample. 749 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 Republic on PIT to DCA

Put together: treat all of this as provisional. 749 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 73.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 732 completed flights over 12 months sit behind that.
