Republic on MCI to DCA sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land roughly 35 minutes behind schedule. That rests on 152 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 999 at 73.1% on time.

The US average over the same twelve months is 77.6%, so there is little to separate Republic on MCI to DCA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on MCI to DCA, 1,926 flights

These figures cover 152 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Carrier by carrier

Republic against every carrier on MCI to DCA

Republic flew 152 of the 1,926 flights on MCI to DCA, about 8% of it. Its 74.8% on time is about level with the route as a whole at 74.8%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from Envoy at 90.2% to PSA at 72.8%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: half a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

On-time performance by carrier on MCI to DCA

PSA Airlines	582	72.8%	136 min	7.04%	C−

PSA Airlines cancels 7.0% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 152 flights.

The early departures do better, though not dramatically: 78.3% on time for the 5am–8am window against 72.1% for 5pm–8pm. Worth taking if the schedule allows, not worth an extra connection. The 5am–8am window is the busiest, with 83 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 74.8% on time across 152 flights.

Split by quarter, Republic on MCI to DCA logged 68 flights in Jul–Sep 2025, 77 flights in Oct–Dec 2025, 1 flights in Jan–Mar 2026 and 6 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 74.8% annual figure is the one to use.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. National Airspace System accounts for 55% of the 1,374 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

55% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 753 minutes out of 1,374, against a national NAS share of 21%. The split is drawn from 1,374 reported delay minutes.

Cancellations are rare at 0.66%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 2.6% land an hour or more behind schedule, against 8.1% 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 949 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg runs 75.5% on time across 152 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 152 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 MCI to DCA

Put together: treat all of this as provisional. 152 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 74.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 151 completed flights over 12 months sit behind that.
