Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3692, 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 3692 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 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 45 minutes. That rests on 346 flights, with a median arrival 12 minutes early.
Set against the rest of the country, OO 3692's record is 10 points better than the US average of 77.6%. That gap is worth roughly 99 fewer late arrivals for every thousand flights.

These figures cover 346 flights between July 2025 and June 2026. The median arrival is 12 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 3692 flies
OO 3692 flies SEA to BOI without a single fixed slot. Its most common scheduled departure was 17:45, used on 162 of 346 flights, with 17:50 (64 flights) and 18:30 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Delay causes
Why OO 3692 runs late
One category carries most of the weight here. Carrier accounts for 80% of the 1,948 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.
- 80%Carrier
- 16%Extreme weather
- 4%National Airspace System
Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.6 times the usual weather exposure. The split is drawn from 1,948 delay minutes reported on OO 3692.
Cancellations are rare at 0.29%, 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 3.2% 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 same number turns up on four other city pairs in the data, including BOI to SEA (25), BTV to DTW (16) and CLE to DTW (1), but none flew often enough under OO 3692 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to BOI only.
One caution: this is a thin sample. 346 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 3692
For a booking, OO 3692 has one of the better records a US domestic flight can show: 87.5% on time and 0.29% cancelled. That is a base rate, not a promise about any single day.
