These figures cover 317 flights between September 2025 and August 2026. The median arrival is 5 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.

Across the year
DL 3024 quarter by quarter
DL 3024 did not run the same all year. Its best quarter was Oct–Dec 2025 at 89.0% on time and its weakest Jan–Mar 2026 at 63.1%, a swing of 26 points on roughly 79 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.

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, DL 3024 did best on Wednesday at 89.1% on time and worst on Thursday at 69.6%. Each day rests on about 45 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes
Why DL 3024 runs late
Carrier accounts for 52% of the 3,648 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 31%Late-arriving aircraft
- 13%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,894 of the 3,648 delay minutes reported here. The split is drawn from 3,648 delay minutes reported on DL 3024.

Connections and routes
What a delay on this flight costs
6.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 55 minutes, which a normal layover absorbs.
The same number turns up on one other city pair in the data, including JAX to ATL (221), but none flew often enough under DL 3024 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to JAX only.
One caution: this is a thin sample. 317 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 3024
For a booking, read DL 3024 as 78.2% on time with 1.26% cancelled over 317 flights. Those are rates from the past twelve months, not a forecast for any particular day.
