Every carrier on IAD to MSP, 1,026 flights

These figures cover 109 flights between September 2025 and August 2026. The median arrival is 14 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 IAD to MSP

Republic flew 109 of the 1,026 flights on IAD to MSP, about 11% of it. Its 83.5% on time is 2 points worse than the route as a whole, which runs 85.9%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Delta at 100.0% to Republic at 83.5%. 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.

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–11am72 flights85.5%
11am–2pm37 flights79.4%
2pm–5pm—
5pm–8pm—
8pm–5am—

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 79.4% on time against 85.5% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8am–11am window is the busiest, with 72 flights scheduled in it.

Split by quarter, Republic on IAD to MSP logged 28 flights in Jan–Mar 2026, 3 flights in Apr–Jun 2026 and 78 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 83.5% annual figure is the one to use.

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 1,176 reported delay minutes.

Carrier
41%
Late-arriving aircraft
35%
National Airspace System
24%

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,176 reported delay minutes here, that single category outweighs weather by 35 to one. The split is drawn from 1,176 reported delay minutes.

The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 482 of the 1,176 delay minutes reported here.

Cancellations run at 4.59%, against 1.89% nationally. That is roughly one flight in twenty 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

Badly late arrivals are rare here: only 3.9% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

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 91.1% on time across 109 flights, 8 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 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 IAD to MSP

Put together: the delay figures matter less here than the 4.59% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 103 completed flights over 12 months sit behind that.
