These figures cover 359 flights between September 2025 and August 2026. The median arrival is 2 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 2276 runs late
Carrier accounts for 54% of the 5,040 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Carrier
- 38%Late-arriving aircraft
- 7%National Airspace System
- 1%Extreme weather
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,040 reported delay minutes here, that single category outweighs weather by 32 to one. The split is drawn from 5,040 delay minutes reported on DL 2276.
Cancellations sit at 1.95% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.8% 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 55 minutes, which a normal layover absorbs.
Every one of the 359 flights under DL 2276 in the data flew ATL to JAX. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 359 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 2276
