Envoy on CMH 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 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 45 minutes. That rests on 315 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 971 at 67.8% on time.
Set against the rest of the country, Envoy's CMH to DCA record is 12 points better than the US average of 77.6%. That gap is worth roughly 115 fewer late arrivals for every thousand flights.

Every carrier on CMH to DCA, 2,055 flights
These figures cover 315 flights between July 2025 and June 2026. The median arrival is 7 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 CMH to DCA
Envoy flew 315 of the 2,055 flights on CMH to DCA, about 15% of it. Its 89.1% on time is 20 points better than the route as a whole, which runs 69.3%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Envoy at 89.1% to Southwest at 60.2%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 3 points 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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |

PSA Airlines cancels 6.5% 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 315 flights.
There are not enough flights in each departure window to split Envoy's CMH to DCA record by time of day without the percentages moving on noise. The headline rate of 89.1% is the reliable figure here.
Across the year
Envoy on CMH to DCA through the year
- Jul–Sep 202591 flights91.2%
- Oct–Dec 202579 flights83.5%
- Jan–Mar 202690 flights88.6%
- Apr–Jun 202655 flights94.5%
Scale runs 75% 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 89.1% on time across 315 flights.
Envoy on CMH to DCA did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.5% on time and its weakest Oct–Dec 2025 at 83.5%, a swing of 11 points on roughly 79 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Wednesday is the strongest day at 97.7% on time and Friday the weakest at 81.8%. 16 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. National Airspace System accounts for 51% of the 1,534 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.
- 51%National Airspace System
- 33%Carrier
- 13%Late-arriving aircraft
- 3%Extreme weather
51% 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 783 minutes out of 1,534, against a national NAS share of 21%. The split is drawn from 1,534 reported delay minutes.
Cancellations are rare at 0.63%, 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 1.3% 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.
At 323 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 74.5% on time across 316 flights, 15 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 15 points of difference.
One caution: this is a thin sample. 315 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 CMH to DCA
Put together: treat all of this as provisional. 315 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 89.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 313 completed flights over 12 months sit behind that.
