These figures cover 343 flights between September 2025 and August 2026. The median arrival is 12 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.

Why OO 3759 runs late
Carrier accounts for 85% of the 2,331 delay minutes carriers reported here, and the remaining four split what is left.
- 85%Carrier
- 11%Extreme weather
- 4%National Airspace System
The largest share of delay minutes, 85%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,975 of the 2,331 delay minutes reported here. The split is drawn from 2,331 delay minutes reported on OO 3759.
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 3.5% 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.
OO 3759 is not only a LAX to SMF flight. It also flew SMF to LAX (262 flights, 88.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 343 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.
