Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5452, 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 5452 draws a C+. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 302 flights, with a median arrival 1 minute early.

The national on-time rate over the same period is 77.6%, so OO 5452 runs 11 points behind the country as a whole. Across a thousand flights that is about 112 extra late arrivals.

These figures cover 302 flights between July 2025 and June 2026. Beyond the headline rate, 11.3% 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 5452 flies

OO 5452 flies RDD to SFO without a single fixed slot. Its most common scheduled departure was 14:09, used on 84 of 302 flights, with 14:10 (70 flights) and 14:19 (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 14:09 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 5452 runs 6 points worse at 66.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5452 quarter by quarter

OO 5452 did not run the same all year. Its best quarter was Jul–Sep 2025 at 85.7% on time and its weakest Apr–Jun 2026 at 40.0%, a swing of 46 points on roughly 76 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 202584 flights85.7%
Oct–Dec 202572 flights68.1%
Jan–Mar 202690 flights63.3%
Apr–Jun 202656 flights40.0%

Scale runs 30% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5452 did best on Tuesday at 79.5% on time and worst on Wednesday at 48.8%. Each day rests on about 43 flights, so a gap of 31 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5452 runs late

One category carries most of the weight here. Carrier accounts for 43% of the 7,746 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.

Extreme weather

The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,330 of the 7,746 delay minutes reported here. The split is drawn from 7,746 delay minutes reported on OO 5452.

Cancellations are rare at 0.33%, 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. 11.3% 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 JAX to ORD (35), but none flew often enough under OO 5452 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDD to SFO only.

One caution: this is a thin sample. 302 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 5452

For a booking, OO 5452 is one of the weaker ways to fly RDD to SFO: 7 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
