Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on DCA to BOS lands a B−, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 198 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 3,983 at 77.9% on time.
Republic Airways is the most reliable of the three carriers covered here at 77.9% on time across 3,983 flights.

These figures cover 198 flights between July 2025 and June 2026. Beyond the headline rate, 10.8% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Envoy against every carrier on DCA to BOS
Envoy flew 198 of the 9,081 flights on DCA to BOS, about 2% of it. Its 76.9% on time is 6 points better than the route as a whole, which runs 71.4%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from Republic at 77.9% to JetBlue at 65.8%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 77.9% of the time; JetBlue Airways manages 65.8%. Sample sizes sit next to every figure, because a two-point gap across 2,633 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |

| Republic Airways | 3,983 | 77.9% | 70 min | 4.22% | B− |

| JetBlue Airways | 2,633 | 65.8% | 90 min | 3.91% | C− |
Republic Airways cancels 4.2% 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 198 flights.
There are not enough flights in each departure window to split Envoy's DCA to BOS record by time of day without the percentages moving on noise. The headline rate of 76.9% is the reliable figure here.
Across the year
Envoy on DCA to BOS through the year
- Jul–Sep 20251 flights—
- Oct–Dec 202545 flights72.1%
- Jan–Mar 202673 flights81.2%
- Apr–Jun 202679 flights75.3%
Scale runs 65% to 85%. 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 76.9% on time across 198 flights.
Quarter by quarter Envoy on DCA to BOS held fairly steady: 72.1% in Oct–Dec 2025, 81.2% in Jan–Mar 2026 and 75.3% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
Across the week, Sunday is the strongest day at 83.9% on time and Wednesday the weakest at 73.3%. 11 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 67% of the 3,224 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.
- 67%Late-arriving aircraft
- 19%Carrier
- 13%National Airspace System
- 1%Extreme weather
67% 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 3,224 reported delay minutes here, that single category outweighs weather by 67 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 3,224 reported delay minutes.
Cancellations run at 6.06%, against 1.81% nationally. That is roughly 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.8% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 399 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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 82.7% on time across 198 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 198 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 DCA to BOS
Put together: the delay figures matter less here than the 6.06% cancellation rate. A late arrival costs you a little over an hour; 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. 186 completed flights over 12 months sit behind that.
