These figures cover 263 flights between September 2025 and August 2026. The median arrival is 9 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 4091 runs late

Carrier accounts for 72% of the 2,455 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
72%
Extreme weather
23%
National Airspace System
5%

Extreme weather accounts for 23% 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 2,455 delay minutes reported on OO 4091.

Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

5.3% 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 an hour, which a normal layover absorbs.

The 677 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.

The same number turns up on two other city pairs in the data, including ABQ to LAX (141) and LAX to PHX (1), but none flew often enough under OO 4091 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to ABQ only.

One caution: this is a thin sample. 263 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 4091

For a booking, OO 4091 has one of the better records a US domestic flight can show: 85.1% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
