These figures cover 325 flights between July 2025 and June 2026. The median arrival is 4 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

When OO 3472 flies

OO 3472 flies SAN to FAT without a single fixed slot. Its most common scheduled departure was 21:59, used on 111 of 325 flights, with 22:20 (45 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 21:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 3472 runs 5 points better at 75.0%. 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 3472 quarter by quarter

OO 3472 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.7% on time and its weakest Jul–Sep 2025 at 68.2%, a swing of 18 points on roughly 81 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 3472 did best on Wednesday at 87.5% on time and worst on Friday at 61.7%. Each day rests on about 46 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3472 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 2,834 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

46% 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 2,834 reported delay minutes here, that single category outweighs weather by 9 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 2,834 delay minutes reported on OO 3472.

Cancellations run at 3.69%, against 1.81% nationally. That is roughly one flight in 25 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

Badly late arrivals are rare here: only 1.9% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

Every one of the 325 flights under OO 3472 in the data flew SAN to FAT. 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. 325 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 3472

For a booking, the cancellation rate is the figure to plan around on OO 3472: 3.69% of its 325 scheduled flights did not operate. A late arrival costs roughly 35 minutes, but a cancellation costs the day, so leave a later option open.
