These figures cover 361 flights between September 2025 and August 2026. The median arrival is 10 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 3117 runs late

Late-arriving aircraft accounts for 43% of the 3,816 delay minutes carriers reported here, and the remaining four split what is left.

43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,816 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 3,816 delay minutes reported on DL 3117.

Cancellations sit at 1.39% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

7.0% 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.

Every one of the 361 flights under DL 3117 in the data flew ATL to JAN. 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. 361 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 3117

For a booking, read DL 3117 as 82.9% on time with 1.39% cancelled over 361 flights. Those are rates from the past twelve months, not a forecast for any particular day.
