These figures cover 311 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 1013 flies

DL 1013 flies ATL to PNS without a single fixed slot. Its most common scheduled departure was 15:20, used on 54 of 311 flights, with 14:45 (54 flights) and 14:36 (37 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 15:20 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1013 runs 13 points better at 85.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1013 quarter by quarter

DL 1013 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.2% on time and its weakest Oct–Dec 2025 at 78.2%, a swing of 12 points on roughly 78 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 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1013 ranged from 79.1% on Saturday to 90.9% on Thursday. With about 44 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1013 runs late

One category carries most of the weight here. Carrier accounts for 49% of the 2,498 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.

Carrier
49%
Late-arriving aircraft
32%
National Airspace System
16%
Extreme weather
2%

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 1,234 of the 2,498 delay minutes reported here. The split is drawn from 2,498 delay minutes reported on DL 1013.

Cancellations are rare at 0.64%, 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

5.5% 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.

DL 1013 is not only a ATL to PNS flight. It also flew PNS to ATL (279 flights, 86.5% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 311 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.
