These figures cover 365 flights between September 2025 and August 2026. The median arrival is 14 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 4115 runs late
Carrier accounts for 99% of the 1,359 delay minutes carriers reported here, and the remaining four split what is left.
- 99%Carrier
- 1%National Airspace System
The largest share of delay minutes, 99%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,351 of the 1,359 delay minutes reported here. The split is drawn from 1,359 delay minutes reported on OO 4115.
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
Badly late arrivals are rare here: only 1.1% 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.
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.
Every one of the 365 flights under OO 4115 in the data flew ABQ to LAX. 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.
What to do with this
Booking OO 4115
For a booking, OO 4115 has one of the better records a US domestic flight can show: 94.5% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
