DL 3083 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 282 flights, with a median arrival 8 minutes early.

Set against the rest of the country, DL 3083's record is 7 points better than the US average of 77.6%. That gap is worth roughly 68 fewer late arrivals for every thousand flights.

These figures cover 282 flights between July 2025 and June 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.

Schedule

When DL 3083 flies

DL 3083 flies ATL to VPS without a single fixed slot. Its most common scheduled departure was 15:54, used on 49 of 282 flights, with 13:59 (36 flights) and 18:29 (30 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 15:54 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 3083 runs 12 points better at 84.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 3083 quarter by quarter

DL 3083 did not run the same all year. Its best quarter was Jan–Mar 2026 at 93.8% on time and its weakest Jul–Sep 2025 at 74.1%, a swing of 20 points on roughly 71 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 flights93.8%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 3083 did best on Tuesday at 91.7% on time and worst on Friday at 73.3%. Each day rests on about 40 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 3083 runs late

One category carries most of the weight here. Carrier accounts for 49% of the 3,144 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.

The largest share of delay minutes, 49%, 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 1,553 of the 3,144 delay minutes reported here. The split is drawn from 3,144 delay minutes reported on DL 3083.

Cancellations sit at 1.77% against a national 1.81%, which is ordinary. Diversions add another 0.71%.

Connections and routes

What a delay on this flight costs

7.3% 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 a little over an hour, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including VPS to ATL (224), but none flew often enough under DL 3083 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to VPS only.

One caution: this is a thin sample. 282 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.

Booking DL 3083
