Delay causes
Why DL 2782 runs late
Late-arriving aircraft accounts for 59% of the 6,143 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 25%Carrier
- 13%National Airspace System
- 3%Extreme weather
59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,143 reported delay minutes here, that single category outweighs weather by 22 to one. The split is drawn from 6,143 delay minutes reported on DL 2782.
Cancellations sit at 2.42% against a national 1.89%, which is ordinary. Diversions add another 0.60%.
Connections and routes
What a delay on this flight costs
10.9% 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.
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.
Every one of the 331 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. 331 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
