These figures cover 109 flights between September 2025 and August 2026. The median arrival is 15 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 MSP to IAD
Republic flew 109 of the 1,024 flights on MSP to IAD, about 11% of it. Its 91.1% on time is 9 points better than the route as a whole, which runs 82.2%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Delta at 100.0% to SkyWest at 80.3%.

Departure window
When Republic runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 109 flights.
- 5am–8am—
- 8am–11am—
- 11am–2pm72 flights93.9%
- 2pm–5pm—
- 5pm–8pm37 flights85.7%
- 8pm–5am—
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 93.9% on time, ahead of 5pm–8pm at 85.7%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 72 flights scheduled in it.

|---|---|---|
| 18 July 2026 | 23 hours 6 minutes | Late-arriving aircraft |
| 7 August 2026 | 2 hours 36 minutes | National Airspace System |
| 6 August 2026 | 1 hour 35 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 80% of the 1,963 delay minutes carriers reported here, and the remaining four split what is left.
- 80%Late-arriving aircraft
- 14%National Airspace System
- 6%Carrier
80% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,963 reported delay minutes here, that single category outweighs weather by 80 to one. The split is drawn from 1,963 reported delay minutes.
Cancellations run at 6.42%, 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
5.0% 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 about 3.6 hours, which a normal layover absorbs.
The 907 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 83.5% on time across 109 flights, 8 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 8 points of difference.
One caution: this is a thin sample. 109 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 MSP to IAD
Put together: the delay figures matter less here than the 6.42% cancellation rate. A late arrival costs you about 3.6 hours; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 101 completed flights over 12 months sit behind that.
