Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on DCA to PIT carries a cancellation problem, not just a delay problem: 3.9% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 749 flights, with a median arrival 3 minutes early.
The national on-time rate over the same period is 77.3%, so Republic on DCA to PIT runs 6 points behind the country as a whole. Across a thousand flights that is about 64 extra late arrivals.

- 8am–11am72 flights80.3%
- 11am–2pm11 flights—

Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 62.4% on time, against 92.8% 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 8pm–5am window is the busiest, with 333 flights scheduled in it.
Across the year
Republic on DCA to PIT through the year
December is the weak month at 58.2% on time, against 89.2% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 84 flights.
Across the week, Saturday is the strongest day at 81.0% on time and Sunday the weakest at 55.7%, a spread of 25 points.

Worst days for Republic on DCA to PIT
The latest arrival of the period was on 9 July 2026, 8 hours 48 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across July, October, August and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 July 2026 | 8 hours 48 minutes | Extreme weather |
| 13 October 2025 | 4 hours 40 minutes | Late-arriving aircraft |
| 14 July 2026 | 4 hours 37 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 48% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 22%Carrier
- 17%National Airspace System
- 13%Extreme weather
Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 12,762 reported delay minutes.
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 4 to one.
Cancellations run at 3.87%, against 1.89% nationally. That is about one flight in 25 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
9.5% 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 73.9% on time across 749 flights, 3 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 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 DCA to PIT
Put together: the delay figures matter less here than the 3.87% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 719 completed flights over 12 months sit behind that.
