DL 3079 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 348 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 3079's record is 9 points better than the US average of 77.6%. That gap is worth roughly 89 fewer late arrivals for every thousand flights.

These figures cover 348 flights between July 2025 and June 2026. The median arrival is 10 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 3079 flies

DL 3079 flies ATL to GNV without a single fixed slot. Its most common scheduled departure was 21:25, used on 117 of 348 flights, with 21:32 (80 flights) and 21:20 (38 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 21:25 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 3079 runs 16 points better at 86.5%. 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 3079 quarter by quarter

Quarter by quarter DL 3079 held fairly steady: 81.5% in Jul–Sep 2025, 89.6% in Oct–Dec 2025, 89.2% in Jan–Mar 2026 and 86.7% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights81.5%
Oct–Dec 202579 flights89.6%
Jan–Mar 202686 flights89.2%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 3079 did best on Saturday at 97.9% on time and worst on Sunday at 78.7%. Each day rests on about 50 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 3079 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 3,802 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.

Extreme weather

National Airspace System

Extreme weather accounts for 26% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.2 times the usual weather exposure. The split is drawn from 3,802 delay minutes reported on DL 3079.

Cancellations sit at 1.72% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.6% 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 an hour and a half, which a normal layover absorbs.

Every one of the 348 flights under DL 3079 in the data flew ATL to GNV. 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. 348 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 3079

For a booking, read DL 3079 as 86.5% on time with 1.72% cancelled over 348 flights. Those are rates from the past twelve months, not a forecast for any particular day.
