These figures cover 365 flights between September 2025 and August 2026. The median arrival is 21 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.

Delay causes

Why OO 4299 runs late

Carrier accounts for 72% of the 8,718 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
72%
Extreme weather
22%
National Airspace System
6%

Extreme weather accounts for 22% 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 3.7 times the usual weather exposure. The split is drawn from 8,718 delay minutes reported on OO 4299.

Cancellations sit at 1.64% against a national 1.89%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

5.9% 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 3.3 hours, which a normal layover absorbs.

Every one of the 365 flights under OO 4299 in the data flew MSP to ATY. 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. 365 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.
