These figures cover 360 flights between July 2025 and June 2026. Beyond the headline rate, 9.0% 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 2329 flies

DL 2329 flies ATL to ORF without a single fixed slot. Its most common scheduled departure was 15:15, used on 40 of 360 flights. 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 15:15 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2329 runs 2 points better at 74.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2329 quarter by quarter

Quarter by quarter DL 2329 held fairly steady: 72.5% in Jul–Sep 2025, 72.7% in Oct–Dec 2025, 73.6% in Jan–Mar 2026 and 78.9% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2329 did best on Wednesday at 84.3% on time and worst on Sunday at 67.3%. Each day rests on about 51 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2329 runs late

One category carries most of the weight here. Carrier accounts for 49% of the 5,409 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.

Carrier
49%
Late-arriving aircraft
27%
National Airspace System
21%
Extreme weather
3%

The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,663 of the 5,409 delay minutes reported here. The split is drawn from 5,409 delay minutes reported on DL 2329.

Cancellations sit at 1.11% 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. 9.0% 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 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. 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.

DL 2329 is not only a ATL to ORF flight. It also flew ORF to ATL (338 flights, 76.7% 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.
