Delay causes
Why DL 2992 runs late
Late-arriving aircraft accounts for 62% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Late-arriving aircraft
- 15%Carrier
- 14%Extreme weather
- 9%National Airspace System
Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 10,150 delay minutes reported on DL 2992.
Cancellations sit at 1.94% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
15.9% 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 700 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 360 flights under DL 2992 in the data flew MIA 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. 360 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 2992
For a booking, DL 2992 is a flight to put a long connection behind. 15.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
