These figures cover 327 flights between September 2025 and August 2026. The median arrival is 7 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.

Delay causes
Why DL 2803 runs late
Carrier accounts for 50% of the 3,649 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 28%Late-arriving aircraft
- 16%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,822 of the 3,649 delay minutes reported here. The split is drawn from 3,649 delay minutes reported on DL 2803.
Cancellations run at 3.06%, against 1.89% 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
6.9% of arrivals land an hour or more late, close to the national 8.3%, so 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.
The same number turns up on one other city pair in the data, including VPS to ATL (199), 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 about an hour, but a cancellation costs the day, so leave a later option open.
