Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4671, 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 4671 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land about 55 minutes behind schedule. That rests on 334 flights, with a median arrival 3 minutes early.

These figures cover 334 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When OO 4671 flies

OO 4671 flies SFO to BFL without a single fixed slot. Its most common scheduled departure was 10:45, used on 109 of 334 flights, with 10:35 (86 flights) and 10:25 (41 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 10:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 4671 runs 12 points worse at 71.9%. 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 4671 quarter by quarter

OO 4671 did not run the same all year. Its best quarter was Oct–Dec 2025 at 77.0% on time and its weakest Apr–Jun 2026 at 63.7%, a swing of 13 points on roughly 84 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 202561 flights77.0%
Jan–Mar 202690 flights72.2%

By weekday, OO 4671 ranged from 68.1% on Saturday to 79.2% on Wednesday. With about 48 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OO 4671 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 5,082 reported delay minutes.

Late-arriving aircraft
34%
National Airspace System
27%
Carrier
22%
Extreme weather
17%

Extreme weather accounts for 17% 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 2.7 times the usual weather exposure. The split is drawn from 5,082 delay minutes reported on OO 4671.

Cancellations are rare at 0.00%, below the national 1.81% 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

8.4% 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 about 55 minutes, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including ORD to CHA (31), but none flew often enough under OO 4671 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to BFL only.

One caution: this is a thin sample. 334 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 4671

For a booking, read OO 4671 as 71.9% on time with 0.00% cancelled over 334 flights. Those are rates from the past twelve months, not a forecast for any particular day.
