These figures cover 360 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

| 26 May 2026 | 4 hours 59 minutes | Late-arriving aircraft |
| 19 July 2026 | 3 hours 57 minutes | Late-arriving aircraft |

Delay causes
Why DL 2329 runs late
Carrier accounts for 44% of the 5,299 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Carrier
- 27%Late-arriving aircraft
- 23%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,346 of the 5,299 delay minutes reported here. The split is drawn from 5,299 delay minutes reported on DL 2329.
Cancellations are rare at 0.83%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
7.8% 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 about an hour, 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.
DL 2329 is not only a ATL to ORF flight. It also flew ORF to ATL (332 flights, 77.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
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.
