These figures cover 270 flights between July 2025 and June 2026. Beyond the headline rate, 16.8% 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.
Schedule
When B6 2783 flies
B6 2783 flies BOS to RDU without a single fixed slot. Its most common scheduled departure was 17:09, used on 32 of 270 flights, with 17:39 (29 flights) and 17:40 (27 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 17:09 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and B6 2783 runs 6 points worse at 62.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
B6 2783 quarter by quarter
B6 2783 did not run the same all year. Its best quarter was Apr–Jun 2026 at 68.5% on time and its weakest Jul–Sep 2025 at 50.0%, a swing of 19 points on roughly 90 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.

By weekday, B6 2783 did best on Wednesday at 77.1% on time and worst on Sunday at 43.6%. Each day rests on about 39 flights, so a gap of 33 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 2783 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 7,206 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.
- 57%Late-arriving aircraft
- 32%Carrier
- 10%National Airspace System
- 1%Extreme weather
57% 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 7,206 reported delay minutes here, that single category outweighs weather by 57 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 7,206 delay minutes reported on B6 2783.
Cancellations run at 2.96%, against 1.81% nationally. That is roughly one flight in 30 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. 16.8% 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.
The 612 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 270 flights under B6 2783 in the data flew BOS to RDU. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 270 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 2783
For a booking, the cancellation rate is the figure to plan around on B6 2783: 2.96% of its 270 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.
