Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3395, 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 3395 sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 260 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so OO 3395 runs 4 points behind the country as a whole. Across a thousand flights that is about 40 extra late arrivals.

These figures cover 260 flights between July 2025 and June 2026. Beyond the headline rate, 15.1% 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 3395 flies

OO 3395 flies STS to SNA without a single fixed slot. Its most common scheduled departure was 11:11, used on 50 of 260 flights, with 14:13 (45 flights) and 11:03 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 11:11 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 3395 runs 5 points worse at 73.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 3395 quarter by quarter

OO 3395 did not run the same all year. Its best quarter was Jan–Mar 2026 at 81.6% on time and its weakest Oct–Dec 2025 at 64.4%, a swing of 17 points on roughly 87 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.

Jul–Sep 202592 flights76.1%
Oct–Dec 202592 flights64.4%
Jan–Mar 202676 flights81.6%

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, OO 3395 did best on Wednesday at 80.6% on time and worst on Friday at 66.7%. Each day rests on about 37 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3395 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 6,369 reported delay minutes.

Extreme weather
36%
Late-arriving aircraft
34%
Carrier
20%
National Airspace System
10%

Extreme weather accounts for 36% 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 5.7 times the usual weather exposure. The split is drawn from 6,369 delay minutes reported on OO 3395.

Cancellations are rare at 0.77%, 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 15.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The same number turns up on one other city pair in the data, including SNA to STS (50), but none flew often enough under OO 3395 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to STS to SNA only.

One caution: this is a thin sample. 260 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 3395

For a booking, OO 3395 is a flight to put a long connection behind. 15.1% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
