These figures cover 334 flights between July 2025 and June 2026. The median arrival is 19 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.

Across the year

OO 4299 quarter by quarter

OO 4299 did not run the same all year. Its best quarter was Jul–Sep 2025 at 98.3% on time and its weakest Oct–Dec 2025 at 80.2%, a swing of 18 points on roughly 84 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Oct–Dec 202592 flights80.2%
Jan–Mar 202690 flights85.9%

By weekday, OO 4299 ranged from 80.9% on Tuesday to 91.7% on Monday. With about 48 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OO 4299 runs late

One category carries most of the weight here. Carrier accounts for 69% of the 7,555 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
69%
Extreme weather
24%
National Airspace System
6%

Extreme weather accounts for 24% 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 3.9 times the usual weather exposure. The split is drawn from 7,555 delay minutes reported on OO 4299.

Cancellations sit at 1.80% against a national 1.81%, which is ordinary. Diversions add another 0.30%.

Connections and routes

What a delay on this flight costs

6.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 3.1 hours, which a normal layover absorbs.

Every one of the 334 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. 334 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.
