Carrier by carrier

Envoy against every carrier on DCA to BOS

Envoy flew 241 of the 9,104 flights on DCA to BOS, about 3% of it. Its 73.1% on time is 3 points better than the route as a whole, which runs 70.1%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from Delta at 87.5% to JetBlue at 63.3%. 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 76.9% of the time; JetBlue Airways manages 63.3%. Sample sizes sit next to every figure, because a two-point gap across 2,624 flights means less than a ten-point one.

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 25 points, against 14 points between the best and worst carrier.

  • 8am–11am—
  • 11am–2pm167 flights80.0%
  • 2pm–5pm1 flights—
  • 5pm–8pm—
  • 8pm–5am73 flights54.8%

Scale runs 45% to 85%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 54.8% on time, against 80.0% for the 11am–2pm 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 11am–2pm 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 73.1% on time across 241 flights.

Envoy on DCA to BOS did not run the same all year. Its best quarter was Jan–Mar 2026 at 81.2% on time and its weakest Jul–Sep 2026 at 55.3%, a swing of 26 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, Sunday is the strongest day at 81.1% on time and Thursday the weakest at 63.9%, a spread of 17 points.

Delay causes

Why Envoy runs late on this route

Late-arriving aircraft accounts for 66% of the 3,917 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    66%
  • Carrier
    19%
  • National Airspace System
    15%
  • Extreme weather
    0%

66% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,917 reported delay minutes here, that single category outweighs weather by 66 to one. The split is drawn from 3,917 reported delay minutes.

Cancellations run at 7.47%, against 1.89% nationally. That is roughly one flight in twelve 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

10.3% 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 11am–2pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 78.5% on time across 241 flights, 5 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 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 DCA to BOS

Put together: the delay figures matter less here than the 7.47% cancellation rate. A late arrival costs you about 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. 223 completed flights over 12 months sit behind that.
