Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3732, 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 3732 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 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 357 flights, with a median arrival 8 minutes early.

Set against the rest of the country, OO 3732's record is 12 points better than the US average of 77.6%. That gap is worth roughly 117 fewer late arrivals for every thousand flights.

These figures cover 357 flights between July 2025 and June 2026. The median arrival is 8 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 3732 flies

OO 3732 flies SLC to RNO without a single fixed slot. Its most common scheduled departure was 16:00, used on 67 of 357 flights, with 15:55 (62 flights) and 16:11 (56 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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 16:00 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 3732 runs 17 points better at 89.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Delay causes

Why OO 3732 runs late

One category carries most of the weight here. Carrier accounts for 70% of the 2,187 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
    70%
  • Extreme weather
    28%
  • National Airspace System
    2%

Extreme weather accounts for 28% 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 4.4 times the usual weather exposure. The split is drawn from 2,187 delay minutes reported on OO 3732.

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 4.5% 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 one other city pair in the data, including RNO to SLC (177), but none flew often enough under OO 3732 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to RNO only.

One caution: this is a thin sample. 357 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 3732

For a booking, OO 3732 has one of the better records a US domestic flight can show: 89.3% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
