Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5805, 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 5805 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 259 flights, with a median arrival 4 minutes early.

These figures cover 259 flights between July 2025 and June 2026. Beyond the headline rate, 11.2% 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 5805 flies

OO 5805 flies SNA to SFO without a single fixed slot. Its most common scheduled departure was 11:53, used on 68 of 259 flights, with 11:58 (49 flights) and 09:45 (37 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 11:53 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5805 runs 6 points worse at 72.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5805 quarter by quarter

OO 5805 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.7% on time and its weakest Apr–Jun 2026 at 53.1%, a swing of 31 points on roughly 86 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 5805 ranged from 65.8% on Sunday to 76.3% on Tuesday. With about 37 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 5805 runs late

One category carries most of the weight here. National Airspace System accounts for 48% of the 5,590 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.

National Airspace System
48%
Late-arriving aircraft
33%
Carrier
19%

48% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,704 minutes out of 5,590, against a national NAS share of 21%. The split is drawn from 5,590 delay minutes reported on OO 5805.

Cancellations are rare at 0.39%, 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. 11.2% 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 two other city pairs in the data, including RAP to DEN (41) and ORD to MLI (14), but none flew often enough under OO 5805 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SNA to SFO only.

One caution: this is a thin sample. 259 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.
