These figures cover 362 flights between September 2025 and August 2026. The median arrival is 14 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 OO 4301 runs late
Carrier accounts for 63% of the 4,396 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Carrier
- 26%Extreme weather
- 11%National Airspace System
Extreme weather accounts for 26% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.3 times the usual weather exposure. The split is drawn from 4,396 delay minutes reported on OO 4301.
Cancellations sit at 1.66% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.7% 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 an hour and a half, which a normal layover absorbs.
The same number turns up on one other city pair in the data, including BRD to MSP (186), but none flew often enough under OO 4301 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to BRD only.
One caution: this is a thin sample. 362 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.
