Historical statistics for July 2025 to June 2026, not live status. For today’s DL 3024, check with Delta Air Lines.

DL 3024 lands a B+, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 317 flights, with a median arrival 6 minutes early.

These figures cover 317 flights between July 2025 and June 2026. The median arrival is 6 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 3024 flies

DL 3024 flies ATL to JAX without a single fixed slot. Its most common scheduled departure was 12:21, used on 58 of 317 flights, with 12:26 (36 flights) and 12:35 (34 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 12:21 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 3024 runs 2 points worse at 76.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 3024 next to ATL to JAX

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.

Jan–Mar 202686 flights63.1%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 3024 did best on Wednesday at 87.0% on time and worst on Sunday at 71.1%. Each day rests on about 45 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 3024 runs late

One category carries most of the weight here. Carrier accounts for 57% of the 4,067 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.

57%
Late-arriving aircraft
27%
National Airspace System
12%
Extreme weather
4%

The largest share of delay minutes, 57%, 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 2,327 of the 4,067 delay minutes reported here. The split is drawn from 4,067 delay minutes reported on DL 3024.

Cancellations are rare at 0.63%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

6.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, 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 76.5% on time with 0.63% cancelled over 317 flights. Those are rates from the past twelve months, not a forecast for any particular day.
