Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3728, 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 3728 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 an hour. That rests on 334 flights, with a median arrival 7 minutes early.
Set against the rest of the country, OO 3728's record is 10 points better than the US average of 77.6%. That gap is worth roughly 101 fewer late arrivals for every thousand flights.

These figures cover 334 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 3728 flies
OO 3728 flies SLC to PSC without a single fixed slot. Its most common scheduled departure was 16:20, used on 56 of 334 flights, with 16:10 (55 flights) and 16:24 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 16:2056 flights16.8%
- Departs 16:1055 flights16.5%
- Departs 16:2435 flights10.5%
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 16:20 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 3728 runs 15 points better at 87.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
OO 3728 quarter by quarter
Quarter by quarter OO 3728 held fairly steady: 91.2% in Jul–Sep 2025, 88.4% in Oct–Dec 2025, 84.4% in Jan–Mar 2026 and 86.8% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202580 flights91.2%
- Oct–Dec 202586 flights88.4%
- Jan–Mar 202677 flights84.4%
- Apr–Jun 202691 flights86.8%
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, OO 3728 did best on Tuesday at 94.1% on time and worst on Wednesday at 81.2%. Each day rests on about 48 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 3728 runs late
One category carries most of the weight here. Carrier accounts for 83% of the 2,379 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.
- 83%Carrier
- 14%Extreme weather
- 3%National Airspace System
Extreme weather accounts for 14% 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 2.2 times the usual weather exposure. The split is drawn from 2,379 delay minutes reported on OO 3728.
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 3.6% 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 521 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 three other city pairs in the data, including PSC to SLC (37), MSP to SDF (3) and SDF to MSP (3), but none flew often enough under OO 3728 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to PSC only.
One caution: this is a thin sample. 334 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 3728
For a booking, OO 3728 has one of the better records a US domestic flight can show: 87.7% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
