Envoy on MCI to DCA earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 168 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 999 at 73.1% on time.
Set against the rest of the country, Envoy's MCI to DCA record is 13 points better than the US average of 77.6%. That gap is worth roughly 126 fewer late arrivals for every thousand flights.

Every carrier on MCI to DCA, 1,926 flights
These figures cover 168 flights between July 2025 and June 2026. The median arrival is 11 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
Envoy against every carrier on MCI to DCA
Envoy flew 168 of the 1,926 flights on MCI to DCA, about 9% of it. Its 90.2% on time is 15 points better than the route as a whole, which runs 74.8%. Ranked by on-time rate it is first 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.

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 Envoy 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 168 flights.
There are not enough flights in each departure window to split Envoy's MCI to DCA record by time of day without the percentages moving on noise. The headline rate of 90.2% is the reliable figure here.
Across the year
Envoy on MCI to DCA through the year
- Jul–Sep 202528 flights—
- Oct–Dec 202541 flights94.9%
- Jan–Mar 202663 flights91.9%
- Apr–Jun 202636 flights88.9%
Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 90.2% on time across 168 flights.
Quarter by quarter Envoy on MCI to DCA held fairly steady: 94.9% in Oct–Dec 2025, 91.9% in Jan–Mar 2026 and 88.9% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
Across the week, Tuesday is the strongest day at 96.9% on time and Wednesday the weakest at 83.9%. 13 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Envoy runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 1,366 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.
- 50%Late-arriving aircraft
- 29%National Airspace System
- 16%Carrier
- 5%Extreme weather
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,366 reported delay minutes here, that single category outweighs weather by 9 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,366 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 92.2% on time here.
Cancellations sit at 2.38% against a national 1.81%, which is ordinary. Diversions add another 0.60%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 3.1% 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 is a different operation and performs like one: it runs 71.6% on time across 168 flights, 19 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 19 points of difference.
One caution: this is a thin sample. 168 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 Envoy on MCI to DCA
Put together: treat all of this as provisional. 168 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 90.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 163 completed flights over 12 months sit behind that.
