These figures cover 339 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.

Delay causes
Why OO 5328 runs late
Late-arriving aircraft accounts for 81% of the 1,726 delay minutes carriers reported here, and the remaining four split what is left.
- 81%Late-arriving aircraft
- 12%Carrier
- 4%Extreme weather
- 3%National Airspace System
81% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,726 reported delay minutes here, that single category outweighs weather by 21 to one. The split is drawn from 1,726 delay minutes reported on OO 5328.
Cancellations are rare at 0.29%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is 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 2.1% 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 same number turns up on four other city pairs in the data, including DEN to OMA (13), SFO to SEA (6) and LAX to PHX (1), but none flew often enough under OO 5328 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RNO to LAX only.
One caution: this is a thin sample. 339 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 5328
For a booking, OO 5328 has one of the better records a US domestic flight can show: 93.2% on time and 0.29% cancelled. That is a base rate, not a promise about any single day.
