Republic on DCA to ROC sits in the middle of the pack with a B−. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land an hour and a half behind schedule. That rests on 154 flights, with a median arrival 3 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on DCA to ROC from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Republic against every carrier on DCA to ROC
Republic flew 154 of the 1,032 flights on DCA to ROC, about 15% of it. Its 75.0% on time is 7 points better than the route as a whole, which runs 67.9%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Envoy at 89.7% to PSA at 64.9%. 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.

Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 75.0% annual figure is the one to use.

The worst days
Worst days for Republic on DCA to ROC
The latest arrival of the period was on 18 May 2026, 7 hours 23 minutes behind schedule; most of its delay minutes were filed as extreme weather. On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 May 2026 | 7 hours 23 minutes | Extreme weather |
| 30 January 2026 | 4 hours 5 minutes | Late-arriving aircraft |
| 18 July 2026 | 3 hours 14 minutes | Extreme weather |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 60% of the 3,080 delay minutes carriers reported here, and the remaining four split what is left.
- 60%Late-arriving aircraft
- 21%Extreme weather
- 10%Carrier
- 9%National Airspace System
Extreme weather accounts for 21% 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 3.4 times the usual weather exposure. The split is drawn from 3,080 reported delay minutes.
60% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,080 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 6.49%, 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
11.8% 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 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 8pm–5am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 78.5% on time across 155 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 154 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 ROC
Put together: the delay figures matter less here than the 6.49% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8pm–5am 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.
