Across the year

Share of 350 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 78 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 36 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORF.

Delay causes
Why DL 1346 runs late
Carrier accounts for 45% of the 5,820 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 27%National Airspace System
- 21%Late-arriving aircraft
- 8%Extreme weather
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,595 of the 5,820 delay minutes reported here. The split is drawn from 5,820 delay minutes reported on DL 1346.
Cancellations sit at 1.13% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
8.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 55 minutes, which a normal layover absorbs.
The 516 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.
The same number turns up on one other city pair in the data, including ORF to ATL (106), but none flew often enough under DL 1346 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to ORF only.
One caution: this is a thin sample. 355 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
