DL 3093 lands a B, about a point better than the national rate of 77.6%. About one flight in five 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 294 flights, with a median arrival 6 minutes early.

These figures cover 294 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 3093 flies

DL 3093 flies ATL to SDF without a single fixed slot. Its most common scheduled departure was 19:59, used on 53 of 294 flights, with 19:52 (32 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 19:59 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 3093 runs 11 points better at 79.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

DL 3093 quarter by quarter

DL 3093 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.6% on time and its weakest Oct–Dec 2025 at 67.3%, a swing of 17 points on roughly 74 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.

Jul–Sep 202585 flights78.8%
Oct–Dec 202553 flights67.3%
Jan–Mar 202678 flights81.6%

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 3093 ranged from 70.6% on Tuesday to 81.6% on Thursday. With about 42 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 3093 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,568 reported delay minutes.

Carrier
39%
Late-arriving aircraft
38%
National Airspace System
16%
Extreme weather
7%

38% 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 3,568 reported delay minutes here, that single category outweighs weather by 5 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 3,568 delay minutes reported on DL 3093.

Cancellations sit at 1.02% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

7.9% 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.

Every one of the 294 flights under DL 3093 in the data flew ATL to SDF. 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. 294 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 3093

For a booking, DL 3093 is one of the weaker ways to fly ATL to SDF: 6 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
