Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4706, 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 4706 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 an hour and a half. That rests on 339 flights, with a median arrival 12 minutes early.

Set against the rest of the country, OO 4706's record is 10 points better than the US average of 77.6%. That gap is worth roughly 102 fewer late arrivals for every thousand flights.

These figures cover 339 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 4706 flies

OO 4706 flies IDA to DEN without a single fixed slot. Its most common scheduled departure was 07:00, used on 211 of 339 flights, with 06:30 (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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 4706 runs level with that at 87.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OO 4706 quarter by quarter

OO 4706 did not run the same all year. Its best quarter was Apr–Jun 2026 at 97.8% on time and its weakest Jul–Sep 2025 at 79.1%, a swing of 19 points on roughly 85 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.

Delay causes

Why OO 4706 runs late

One category carries most of the weight here. Carrier accounts for 85% of the 3,813 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
    85%
  • Extreme weather
    10%
  • National Airspace System
    4%
  • Late-arriving aircraft
    1%

The largest share of delay minutes, 85%, 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 3,244 of the 3,813 delay minutes reported here. The split is drawn from 3,813 delay minutes reported on OO 4706.

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

5.6% 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 an hour and a half, which a normal layover absorbs.

The same number turns up on two other city pairs in the data, including ORD to ATW (24) and DTW to ORD (1), but none flew often enough under OO 4706 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IDA to DEN only.

One caution: this is a thin sample. 339 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 4706

For a booking, OO 4706 has one of the better records a US domestic flight can show: 87.8% on time and 0.29% cancelled. That is a base rate, not a promise about any single day.
