Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3298, 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 3298 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 293 flights, with a median arrival 6 minutes early.

These figures cover 293 flights between July 2025 and June 2026. The median arrival is 6 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 3298 flies
OO 3298 flies SEA to SLC without a single fixed slot. Its most common scheduled departure was 19:16, used on 49 of 293 flights, with 18:10 (47 flights) and 18:40 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 19:1649 flights16.7%
- Departs 18:1047 flights16.0%
- Departs 18:4045 flights15.4%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 19:16 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 3298 runs 12 points better at 80.5%. 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 3298 quarter by quarter
Quarter by quarter OO 3298 held fairly steady: 78.0% in Jul–Sep 2025, 82.4% in Oct–Dec 2025 and 81.3% 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.
- Jul–Sep 202591 flights78.0%
- Oct–Dec 202591 flights82.4%
- Jan–Mar 202620 flights—

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, OO 3298 did best on Saturday at 88.1% on time and worst on Friday at 58.5%. Each day rests on about 42 flights, so a gap of 30 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 3298 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 78% of the 2,952 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.
- 78%Late-arriving aircraft
- 16%Carrier
- 3%National Airspace System
- 2%Extreme weather
78% 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 2,952 reported delay minutes here, that single category outweighs weather by 35 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 2,952 delay minutes reported on OO 3298.
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
6.1% 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 roughly 50 minutes, which a normal layover absorbs.
The 689 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.
The same number turns up on one other city pair in the data, including PDX to GEG (59), but none flew often enough under OO 3298 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to SLC only.
One caution: this is a thin sample. 293 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 3298
For a booking, read OO 3298 as 80.5% on time with 0.00% cancelled over 293 flights. Those are rates from the past twelve months, not a forecast for any particular day.
