Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2803, check with Delta Air Lines.

DL 2803 lands a B−, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 327 flights, with a median arrival 8 minutes early.

Set against the rest of the country, DL 2803's record is 5 points better than the US average of 77.6%. That gap is worth roughly 50 fewer late arrivals for every thousand flights.

These figures cover 327 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 2803 flies

DL 2803 flies ATL to VPS without a single fixed slot. Its most common scheduled departure was 18:28, used on 68 of 327 flights, with 15:56 (46 flights) and 18:30 (39 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 18:28 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2803 runs 14 points better at 82.6%. 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 2803 quarter by quarter

Quarter by quarter DL 2803 held fairly steady: 80.2% in Jul–Sep 2025, 87.2% in Oct–Dec 2025, 81.7% in Jan–Mar 2026 and 81.8% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2803 ranged from 79.5% on Sunday to 87.0% on Friday. With about 47 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2803 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 2,815 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.

Late-arriving aircraft
24%
National Airspace System
15%
Extreme weather
7%

The largest share of delay minutes, 55%, 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 1,547 of the 2,815 delay minutes reported here. The split is drawn from 2,815 delay minutes reported on DL 2803.

Cancellations run at 3.06%, against 1.81% nationally. That is roughly one flight in 30 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 4.7% 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.

The same number turns up on one other city pair in the data, including VPS to ATL (228), but none flew often enough under DL 2803 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. 327 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 2803

For a booking, the cancellation rate is the figure to plan around on DL 2803: 3.06% of its 327 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
