B6 1355 earns a D−, which is as low as this site's scale goes for a reason. Only 55.0% of flights arrive inside the 15-minute window, 23 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 271 flights, with a median arrival 10 minutes late.

The national on-time rate over the same period is 77.6%, so B6 1355 runs 23 points behind the country as a whole. Across a thousand flights that is about 226 extra late arrivals.

These figures cover 271 flights between July 2025 and June 2026. Beyond the headline rate, 19.1% 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.

Schedule

When B6 1355 flies

B6 1355 flies BOS to DCA without a single fixed slot. Its most common scheduled departure was 16:15, used on 55 of 271 flights, with 14:30 (32 flights) and 14:59 (29 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 16:15 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and B6 1355 runs 17 points worse at 55.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 1355 quarter by quarter

B6 1355 did not run the same all year. Its best quarter was Apr–Jun 2026 at 59.5% on time and its weakest Oct–Dec 2025 at 42.6%, a swing of 17 points on roughly 68 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.

Jul–Sep 202554 flights58.7%
Oct–Dec 202559 flights42.6%
Jan–Mar 202683 flights57.1%
Apr–Jun 202675 flights59.5%

Scale runs 35% to 65%. Rows with fewer than 30 flights show a dash.

By weekday, B6 1355 did best on Tuesday at 71.8% on time and worst on Thursday at 42.5%. Each day rests on about 39 flights, so a gap of 29 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 1355 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 8,851 reported delay minutes.

Late-arriving aircraft
42%
National Airspace System
40%
Carrier
18%

42% 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 8,851 reported delay minutes here, that single category outweighs weather by 42 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 8,851 delay minutes reported on B6 1355.

Cancellations run at 7.01%, against 1.81% 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 routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 19.1% 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.

The same number turns up on one other city pair in the data, including JFK to DCA (45), but none flew often enough under B6 1355 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to DCA only.

One caution: this is a thin sample. 271 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 B6 1355

For a booking, the cancellation rate is the figure to plan around on B6 1355: 7.01% of its 271 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
