Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4696, 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 4696 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 11 points better than the national rate of 77.6%.

These figures cover 314 flights between July 2025 and June 2026. The median arrival is 14 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 4696 flies

OO 4696 flies COS to DEN without a single fixed slot. Its most common scheduled departure was 07:00, used on 177 of 314 flights, with 05:30 (79 flights) and 07:05 (47 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 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 4696 runs level with that at 88.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why OO 4696 runs late

One category carries most of the weight here. Carrier accounts for 85% of the 2,035 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%
National Airspace System
8%
Extreme weather
7%

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 1,727 of the 2,035 delay minutes reported here. The split is drawn from 2,035 delay minutes reported on OO 4696.

Cancellations are rare at 0.64%, 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

Badly late arrivals are rare here: only 3.2% 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 four other city pairs in the data, including MLI to ORD (32), LAX to SLC (9) and BOI to DEN (5), but none flew often enough under OO 4696 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to COS to DEN only.

One caution: this is a thin sample. 314 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 4696

For a booking, OO 4696 has one of the better records a US domestic flight can show: 88.5% on time and 0.64% cancelled. That is a base rate, not a promise about any single day.
