Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5796, 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 5796 lands a B−, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 358 flights, with a median arrival 5 minutes early.

These figures cover 358 flights between July 2025 and June 2026. The median arrival is 5 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

OO 5796 flies SFO to SMF without a single fixed slot. Its most common scheduled departure was 18:45, used on 194 of 358 flights, with 18:50 (48 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 18:45 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 5796 runs 13 points better at 80.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

OO 5796 quarter by quarter

OO 5796 did not run the same all year. Its best quarter was Jul–Sep 2025 at 89.0% on time and its weakest Jan–Mar 2026 at 76.7%, a swing of 12 points on roughly 90 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.

Oct–Dec 202589 flights76.8%
Jan–Mar 202688 flights76.7%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5796 did best on Saturday at 87.2% on time and worst on Thursday at 74.0%. Each day rests on about 51 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5796 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,604 reported delay minutes.

Late-arriving aircraft
41%
Carrier
35%
National Airspace System
22%
Extreme weather
2%

41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,604 reported delay minutes here, that single category outweighs weather by 19 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,604 delay minutes reported on OO 5796.

Cancellations run at 3.07%, against 1.81% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

7.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.

Every one of the 358 flights under OO 5796 in the data flew SFO to SMF. 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. 358 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 5796

For a booking, the cancellation rate is the figure to plan around on OO 5796: 3.07% of its 358 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
