Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1346, check with Delta Air Lines.
DL 1346 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 10 points worse than the national rate of 77.6%. The late ones land roughly 55 minutes behind schedule. That rests on 355 flights, with a median arrival 3 minutes late.
The national on-time rate over the same period is 77.6%, so DL 1346 runs 10 points behind the country as a whole. Across a thousand flights that is about 95 extra late arrivals.

These figures cover 355 flights between July 2025 and June 2026. Beyond the headline rate, 9.1% 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 1346 flies
DL 1346 flies ATL to ORF without a single fixed slot. Its most common scheduled departure was 17:00, used on 53 of 355 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 17:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 1346 runs level with that at 68.1%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
DL 1346 quarter by quarter
DL 1346 did not run the same all year. Its best quarter was Jan–Mar 2026 at 78.8% on time and its weakest Jul–Sep 2025 at 62.9%, a swing of 16 points on roughly 89 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202591 flights63.3%
- Jan–Mar 202687 flights78.8%

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1346 did best on Wednesday at 82.7% on time and worst on Sunday at 52.1%. Each day rests on about 51 flights, so a gap of 31 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1346 runs late
One category carries most of the weight here. Carrier accounts for 46% of the 5,887 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.
- 46%Carrier
- 28%National Airspace System
- 19%Late-arriving aircraft
- 7%Extreme weather
- 1%Security
The largest share of delay minutes, 46%, 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 2,698 of the 5,887 delay minutes reported here. The split is drawn from 5,887 delay minutes reported on DL 1346.
Cancellations sit at 1.13% 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. 9.1% 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.
The same number turns up on one other city pair in the data, including ORF to ATL (120), 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.
