Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3729, 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 3729 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 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 45 minutes. That rests on 348 flights, with a median arrival 11 minutes early.

Set against the rest of the country, OO 3729's record is 14 points better than the US average of 77.6%. That gap is worth roughly 140 fewer late arrivals for every thousand flights.

These figures cover 348 flights between July 2025 and June 2026. The median arrival is 11 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 3729 flies

OO 3729 flies SLC to ABQ without a single fixed slot. Its most common scheduled departure was 20:45, used on 122 of 348 flights, with 20:40 (106 flights) and 21:45 (41 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 20:45 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 3729 runs 21 points better at 91.6%. 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 3729 quarter by quarter

OO 3729 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.8% on time and its weakest Apr–Jun 2026 at 83.5%, a swing of 14 points on roughly 87 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, OO 3729 ranged from 88.0% on Friday to 94.1% on Tuesday. With about 50 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OO 3729 runs late

One category carries most of the weight here. Carrier accounts for 89% of the 1,327 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
    89%
  • Extreme weather
    8%
  • National Airspace System
    3%

The largest share of delay minutes, 89%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,186 of the 1,327 delay minutes reported here. The split is drawn from 1,327 delay minutes reported on OO 3729.

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 2.0% 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 RIC to DTW (16), but none flew often enough under OO 3729 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to ABQ only.

One caution: this is a thin sample. 348 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 3729

For a booking, OO 3729 has one of the better records a US domestic flight can show: 91.6% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
