Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3413, 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 3413 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 55 minutes. That rests on 323 flights, with a median arrival 15 minutes early.

Set against the rest of the country, OO 3413's record is 9 points better than the US average of 77.6%. That gap is worth roughly 90 fewer late arrivals for every thousand flights.

These figures cover 323 flights between July 2025 and June 2026. The median arrival is 15 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 3413 flies

OO 3413 flies SJC to BOI without a single fixed slot. Its most common scheduled departure was 19:22, used on 71 of 323 flights, with 16:58 (44 flights) and 17:03 (43 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 19:22 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 3413 runs 18 points better at 86.6%. 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 3413 quarter by quarter

OO 3413 did not run the same all year. Its best quarter was Jan–Mar 2026 at 92.9% on time and its weakest Apr–Jun 2026 at 80.7%, a swing of 12 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 3413 did best on Wednesday at 95.7% on time and worst on Thursday at 78.3%. Each day rests on about 46 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3413 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 66% of the 2,362 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.

66%
Carrier
16%
National Airspace System

Extreme weather
7%

66% 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 2,362 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 2,362 delay minutes reported on OO 3413.

Cancellations are rare at 0.31%, 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

Badly late arrivals are rare here: only 3.7% 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.

The 523 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 323 flights under OO 3413 in the data flew SJC to BOI. 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. 323 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 3413

For a booking, OO 3413 has one of the better records a US domestic flight can show: 86.6% on time and 0.31% cancelled. That is a base rate, not a promise about any single day.
