Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5897, check with SkyWest Airlines. SkyWest Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

OO 5897 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 356 flights, with a median arrival 8 minutes early.

These figures cover 356 flights between July 2025 and June 2026. The median arrival is 8 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.

Schedule

When OO 5897 flies

OO 5897 flies SBP to LAX without a single fixed slot. Its most common scheduled departure was 06:00, used on 90 of 356 flights, with 06:05 (56 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5897 runs level with that at 87.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OO 5897 quarter by quarter

OO 5897 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.6% on time and its weakest Oct–Dec 2025 at 77.3%, a swing of 18 points on roughly 89 flights a 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.

By weekday, OO 5897 did best on Wednesday at 98.0% on time and worst on Monday at 82.7%. Each day rests on about 51 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5897 runs late

One category carries most of the weight here. Carrier accounts for 46% of the 4,740 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
46%
Extreme weather
27%
Late-arriving aircraft
20%
National Airspace System
8%

Extreme weather accounts for 27% 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 4.3 times the usual weather exposure. The split is drawn from 4,740 delay minutes reported on OO 5897.

Cancellations are rare at 0.28%, below the national 1.81% 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 4.5% land an hour or more behind schedule, against 8.1% 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.

Every one of the 356 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. 356 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: 87.6% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
