Envoy on BOS to DCA lands a B−, about a point better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 241 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 3,999 at 75.1% on time.

The US average over the same twelve months is 77.3%, so there is little to separate Envoy on BOS to DCA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier

Envoy against every carrier on BOS to DCA

Envoy flew 241 of the 9,105 flights on BOS to DCA, about 3% of it. Its 78.5% on time is 6 points better than the route as a whole, which runs 72.6%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from Envoy at 78.5% to Delta at 42.9%. 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 75.1% of the time; JetBlue Airways manages 66.3%. Sample sizes sit next to every figure, because a two-point gap across 2,626 flights means less than a ten-point one.

JetBlue Airways cancels 4.9% 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 matters more here than the choice of carrier. The gap between the best and worst window is 28 points, against 9 points between the best and worst carrier.

5am–8am—
8am–11am167 flights86.2%
11am–2pm—
2pm–5pm—
5pm–8pm1 flights—
8pm–5am73 flights58.7%

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 58.7% on time, against 86.2% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 167 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 78.5% on time across 241 flights.

Envoy on BOS to DCA did not run the same all year. Its best quarter was Jan–Mar 2026 at 88.4% on time and its weakest Jul–Sep 2026 at 56.4%, a swing of 32 points on roughly 60 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, Tuesday is the strongest day at 84.2% on time and Thursday the weakest at 73.0%, a spread of 11 points.

Arrival by arrival

The worst days

Worst days for Envoy on BOS to DCA

The latest arrival of the period was on 20 July 2026, 4 hours 2 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 65% of the 3,247 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System
19%
Carrier

Extreme weather

Security

65% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,247 reported delay minutes here, that single category outweighs weather by 65 to one. The split is drawn from 3,247 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 86.2% on time here.

Cancellations run at 6.64%, against 1.89% nationally. That is about 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

9.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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 8am–11am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 73.1% on time across 241 flights, 5 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 5 points of difference.

One caution: this is a thin sample. 241 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 BOS to DCA

Put together: the delay figures matter less here than the 6.64% cancellation rate. A late arrival costs you about 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. 223 completed flights over 12 months sit behind that.
