Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on DCA to MSN lands a B, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 375 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on DCA to MSN from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

When Republic runs best on this route

There are not enough flights in each departure window to split Republic's DCA to MSN record by time of day without the percentages moving on noise. The headline rate of 76.0% is the reliable figure here.

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 44% of the 7,168 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 31%National Airspace System
- 23%Carrier
- 3%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,168 reported delay minutes here, that single category outweighs weather by 14 to one. The split is drawn from 7,168 reported delay minutes.
Cancellations sit at 2.40% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
11.5% 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.
The 707 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 69.4% on time across 375 flights, 7 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 7 points of difference.
One caution: this is a thin sample. 375 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 MSN
Put together: treat all of this as provisional. 375 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 76.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 366 completed flights over 12 months sit behind that.
