Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3394, 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 3394 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 310 flights, with a median arrival 19 minutes early.

Set against the rest of the country, OO 3394's record is 13 points better than the US average of 77.6%. That gap is worth roughly 127 fewer late arrivals for every thousand flights.

These figures cover 310 flights between July 2025 and June 2026. The median arrival is 19 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 3394 flies

OO 3394 flies LAX to BOI without a single fixed slot. Its most common scheduled departure was 19:45, used on 220 of 310 flights, with 19:50 (49 flights) and 19:49 (41 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 19:45 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 3394 runs 22 points better at 90.3%. 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 3394 quarter by quarter

Quarter by quarter OO 3394 held fairly steady: 91.2% in Jul–Sep 2025, 87.7% in Oct–Dec 2025, 91.7% in Jan–Mar 2026 and 90.0% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, OO 3394 did best on Tuesday at 97.8% on time and worst on Sunday at 79.5%. Each day rests on about 44 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3394 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 2,386 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.

Carrier
44%
Late-arriving aircraft
40%
National Airspace System
13%
Security
3%

40% 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 2,386 reported delay minutes here, that single category outweighs weather by 40 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 2,386 delay minutes reported on OO 3394.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

6.5% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

The 674 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 310 flights under OO 3394 in the data flew LAX 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. 310 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 3394

For a booking, OO 3394 has one of the better records a US domestic flight can show: 90.3% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
