These figures cover 333 flights between July 2025 and June 2026. The median arrival is 22 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.

Schedule

When OO 4298 flies

OO 4298 flies ATY to MSP without a single fixed slot. Its most common scheduled departure was 05:10, used on 138 of 333 flights, with 06:45 (115 flights) and 05:15 (40 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 05:10 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 4298 runs 3 points better at 92.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why OO 4298 runs late

One category carries most of the weight here. Carrier accounts for 72% of the 5,333 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
72%
Extreme weather
24%
National Airspace System
4%

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 3.8 times the usual weather exposure. The split is drawn from 5,333 delay minutes reported on OO 4298.

Cancellations sit at 1.80% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.9% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

Every one of the 333 flights under OO 4298 in the data flew ATY to MSP. 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. 333 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 OO 4298
