These figures cover 264 flights between September 2025 and August 2026. The median arrival is 8 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 3034 runs late
Carrier accounts for 61% of the 1,755 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Carrier
- 30%National Airspace System
- 6%Late-arriving aircraft
- 3%Extreme weather
The largest share of delay minutes, 61%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,077 of the 1,755 delay minutes reported here. The split is drawn from 1,755 delay minutes reported on DL 3034.
Cancellations run at 2.65%, against 1.89% nationally. That is about one flight in 40 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 3.9% 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.
Every one of the 264 flights under DL 3034 in the data flew ATL to DAB. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 264 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 3034
For a booking, the cancellation rate is the figure to plan around on DL 3034: 2.65% of its 264 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
