Carrier by carrier
Republic against every carrier on MSN to DCA
Republic flew 375 of the 1,238 flights on MSN to DCA, about 30% of it. Its 69.4% on time is 4 points worse than the route as a whole, which runs 72.9%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Envoy at 100.0% to Republic at 69.4%. 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.

Share of 359 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 88 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 28 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 MSN to DCA
The latest arrival of the period was on 20 May 2026, 5 hours 9 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across May, August, March and June, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 May 2026 | 5 hours 9 minutes | Carrier |
| 16 August 2026 | 3 hours 50 minutes | Extreme weather |
| 16 August 2026 | 3 hours 40 minutes | Extreme weather |

Delay causes
Why Republic runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 8,441 reported delay minutes.
- 37%Late-arriving aircraft
- 31%National Airspace System
- 18%Carrier
- 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 8,441 reported delay minutes.
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,441 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 3.47%, against 1.89% nationally. That is about one flight in 30 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
14.8% 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.
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 76.0% on time across 375 flights, 7 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 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 MSN to DCA
Put together: the delay figures matter less here than the 3.47% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5pm–8pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 359 completed flights over 12 months sit behind that.
