OO 4264 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%.

These figures cover 364 flights between September 2025 and August 2026. The median arrival is 15 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 4264 quarter by quarter

Delay causes

Why OO 4264 runs late

Carrier accounts for 56% of the 5,658 delay minutes carriers reported here, and the remaining four split what is left.

Extreme weather accounts for 36% 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 6.0 times the usual weather exposure. The split is drawn from 5,658 delay minutes reported on OO 4264.

Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.5% land an hour or more behind schedule, against 8.3% 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 364 flights under OO 4264 in the data flew MSP to ABR. 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. 364 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 4264

For a booking, OO 4264 has one of the better records a US domestic flight can show: 87.2% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
