Republic on ROC to DCA lands a B−, about a point better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 155 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on ROC 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 155 flights between September 2025 and August 2026. The median arrival is 7 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 ROC to DCA
Republic flew 155 of the 1,033 flights on ROC to DCA, about 15% of it. Its 78.5% on time is 12 points better than the route as a whole, which runs 67.0%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Envoy at 84.5% to PSA at 63.5%. One 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 30 points, against half a point between the best and worst carrier.

The 5pm–8pm window is where this operation falls apart: 57.5% on time, against 87.8% 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 5am–8am window is the busiest, with 104 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 78.5% on time across 155 flights.
Split by quarter, Republic on ROC to DCA logged 8 flights in Jul–Sep 2025, 38 flights in Oct–Dec 2025, 73 flights in Jan–Mar 2026, 26 flights in Apr–Jun 2026 and 10 flights in Jul–Sep 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 78.5% annual figure is the one to use.
Arrival by arrival
How late Republic on ROC to DCA runs when it is late
Republic on ROC to DCA often beats the schedule: 55 of 144 completed flights, 38%, arrived 15 minutes or more early. The 31 late arrivals split 9 under half an hour, 11 between 30 and 60 minutes, and 11 an hour or more.

Share of 144 completed flights by arrival against schedule.
3 of 25 late departures made up the time and arrived on time, 12% of them. In the other direction, 9 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 Republic on ROC to DCA
The latest arrival of the period was on 16 December 2025, 5 hours 44 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 December 2025 | 5 hours 44 minutes | Carrier |
| 21 April 2026 | 5 hours 28 minutes | Carrier |
| 30 January 2026 | 4 hours 32 minutes | Late-arriving aircraft |
| 4 February 2026 | 2 hours 44 minutes | Carrier |

Delay causes
Why Republic runs late on this route
Carrier accounts for 43% of the 2,638 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Carrier
- 33%Late-arriving aircraft
- 17%National Airspace System
- 7%Extreme weather
The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,137 of the 2,638 delay minutes reported here. The split is drawn from 2,638 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 87.8% on time here.
Cancellations run at 6.45%, against 1.89% nationally. That is about one flight in fifteen 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
7.6% 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 an hour and a half, which a normal layover absorbs.
At 296 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 75.0% on time across 154 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 155 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 ROC to DCA
Put together: the delay figures matter less here than the 6.45% cancellation rate. A late arrival costs you an hour and a half; 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. 144 completed flights over 12 months sit behind that.
