Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1336, check with Delta Air Lines.

DL 1336 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 297 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 1336's record is 14 points better than the US average of 77.6%. That gap is worth roughly 140 fewer late arrivals for every thousand flights.

These figures cover 297 flights between July 2025 and June 2026. The median arrival is 12 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When DL 1336 flies

DL 1336 flies ORF to ATL without a single fixed slot. Its most common scheduled departure was 10:15, used on 33 of 297 flights, with 10:07 (32 flights) and 10:57 (31 flights) next. 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 10:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1336 runs 8 points better at 91.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 1336 next to ORF to ATL

Across the year

DL 1336 quarter by quarter

Quarter by quarter DL 1336 held fairly steady: 94.9% in Jul–Sep 2025, 90.4% in Oct–Dec 2025, 91.1% in Jan–Mar 2026 and 90.8% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 1336 did best on Thursday at 95.6% on time and worst on Sunday at 83.3%. Each day rests on about 42 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1336 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 66% of the 1,178 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.

Late-arriving aircraft
66%
Carrier
19%
National Airspace System
15%

66% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,178 reported delay minutes here, that single category outweighs weather by 66 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,178 delay minutes reported on DL 1336.

Cancellations run at 3.37%, against 1.81% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 1.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

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 1336 is not only a ORF to ATL flight. It also flew ATL to ORF (272 flights, 91.2% 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. 297 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 1336

For a booking, the cancellation rate is the figure to plan around on DL 1336: 3.37% of its 297 scheduled flights did not operate. A late arrival costs about 50 minutes, but a cancellation costs the day, so leave a later option open.
