These figures cover 303 flights between September 2025 and August 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.

Delay causes

Why DL 1336 runs late

Late-arriving aircraft accounts for 62% of the 1,307 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
62%
Carrier
22%
National Airspace System
16%

62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,307 reported delay minutes here, that single category outweighs weather by 62 to one. The split is drawn from 1,307 delay minutes reported on DL 1336.

Cancellations run at 3.30%, against 1.89% 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 2.1% land an hour or more behind schedule, against 8.3% 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.

DL 1336 is not only a ORF to ATL flight. It also flew ATL to ORF (278 flights, 91.4% 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. 303 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: 3.30% of its 303 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
