DL 3103 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 15 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 14 minutes early.

Set against the rest of the country, DL 3103's record is 15 points better than the US average of 77.6%. That gap is worth roughly 147 fewer late arrivals for every thousand flights.

These figures cover 348 flights between July 2025 and June 2026. The median arrival is 14 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 3103 flies

DL 3103 flies PNS to ATL without a single fixed slot. Its most common scheduled departure was 09:23, used on 52 of 348 flights, with 09:15 (36 flights) and 09:20 (35 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 09:23 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 3103 runs 8 points better at 92.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 3103 quarter by quarter

Quarter by quarter DL 3103 held fairly steady: 95.6% in Jul–Sep 2025, 91.1% in Oct–Dec 2025, 87.5% in Jan–Mar 2026 and 94.3% 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.

By weekday, DL 3103 did best on Friday at 98.0% on time and worst on Sunday at 84.4%. Each day rests on about 50 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 3103 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 2,392 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

52% 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 2,392 reported delay minutes here, that single category outweighs weather by 23 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 2,392 delay minutes reported on DL 3103.

Cancellations run at 2.59%, against 1.81% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.6% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

DL 3103 is not only a PNS to ATL flight. It also flew ATL to PNS (348 flights, 91.7% 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. 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 3103
