These figures cover 326 flights between July 2025 and June 2026. Beyond the headline rate, 11.9% 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 DL 2782 flies

DL 2782 flies BOS to RDU without a single fixed slot. Its most common scheduled departure was 17:05, used on 69 of 326 flights, with 16:20 (44 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 17:05 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2782 runs 6 points better at 74.0%. 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

DL 2782 quarter by quarter

DL 2782 did not run the same all year. Its best quarter was Jan–Mar 2026 at 82.2% on time and its weakest Jul–Sep 2025 at 65.8%, a swing of 16 points on roughly 82 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.

Oct–Dec 202586 flights68.7%
Jan–Mar 202676 flights82.2%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2782 did best on Tuesday at 87.8% on time and worst on Sunday at 60.5%. Each day rests on about 47 flights, so a gap of 27 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2782 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 56% of the 6,195 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.

Extreme weather
2%

56% 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 6,195 reported delay minutes here, that single category outweighs weather by 23 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 6,195 delay minutes reported on DL 2782.

Cancellations sit at 2.15% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 11.9% 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 326 flights under DL 2782 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. 326 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 DL 2782
