These figures cover 271 flights between September 2025 and August 2026. The median arrival is 17 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.

Connections and routes
What a delay on this flight costs
6.0% 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 2.9 hours, which a normal layover absorbs.
The same number turns up on two other city pairs in the data, including ATL to MOB (13) and MOB to ATL (13), but none flew often enough under OO 3930 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DLH to MSP only.
One caution: this is a thin sample. 271 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
