Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3415, 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 3415 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 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 50 minutes. That rests on 286 flights, with a median arrival 7 minutes early.
Set against the rest of the country, OO 3415's record is 8 points better than the US average of 77.6%. That gap is worth roughly 81 fewer late arrivals for every thousand flights.

These figures cover 286 flights between July 2025 and June 2026. The median arrival is 7 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 3415 flies
OO 3415 flies BOI to BUR without a single fixed slot. Its most common scheduled departure was 12:29, used on 50 of 286 flights, with 13:01 (40 flights) and 11:01 (35 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 12:29 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 3415 runs 7 points better at 85.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

- Jul–Sep 202592 flights82.6%
- Oct–Dec 202570 flights87.1%
- Jan–Mar 202654 flights81.5%

By weekday, OO 3415 did best on Saturday at 95.0% on time and worst on Friday at 75.6%. Each day rests on about 41 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 3415 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 1,973 reported delay minutes.
- 39%Carrier
- 36%Late-arriving aircraft
- 20%National Airspace System
- 5%Extreme weather
36% 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 1,973 reported delay minutes here, that single category outweighs weather by 7 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 1,973 delay minutes reported on OO 3415.
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
Badly late arrivals are rare here: only 3.1% 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 656 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 286 flights under OO 3415 in the data flew BOI to BUR. 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. 286 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 3415
For a booking, OO 3415 has one of the better records a US domestic flight can show: 85.7% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
