These figures cover 336 flights between September 2025 and August 2026. The median arrival is 7 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 5897 quarter by quarter

The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 335 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 23 departures that left 15 minutes late or more, only 1 made it up before arrival. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LAX.
The worst days
Worst days for OO 5897
The latest arrival of the period was on 12 June 2026, 8 hours 47 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across June, April, September, November and May, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 June 2026 | 8 hours 47 minutes | Late-arriving aircraft |
| 21 April 2026 | 6 hours 52 minutes | Late-arriving aircraft |
| 19 September 2025 | 5 hours 47 minutes | Carrier |

Delay causes
Why OO 5897 runs late
Carrier accounts for 49% of the 4,987 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 25%Extreme weather
- 19%Late-arriving aircraft
- 7%National Airspace System
Extreme weather accounts for 25% 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 4.2 times the usual weather exposure. The split is drawn from 4,987 delay minutes reported on OO 5897.
Cancellations are rare at 0.30%, 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
5.1% 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 close to two hours, which a normal layover absorbs.
Every one of the 336 flights under OO 5897 in the data flew SBP 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. 336 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 5897
For a booking, OO 5897 has one of the better records a US domestic flight can show: 86.9% on time and 0.30% cancelled. That is a base rate, not a promise about any single day.
