Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5246, 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 5246 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 351 flights, with a median arrival 11 minutes early.

Set against the rest of the country, OO 5246's record is 8 points better than the US average of 77.6%. That gap is worth roughly 75 fewer late arrivals for every thousand flights.

These figures cover 351 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 5246 flies

OO 5246 flies DEN to COS without a single fixed slot. Its most common scheduled departure was 07:45, used on 149 of 351 flights, with 08:10 (64 flights) and 08:14 (48 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 07:45 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5246 runs 4 points worse at 85.1%. 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 5246 quarter by quarter

By weekday, OO 5246 did best on Monday at 92.3% on time and worst on Thursday at 76.9%. Each day rests on about 50 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5246 runs late

One category carries most of the weight here. Carrier accounts for 67% of the 2,561 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
67%
Late-arriving aircraft
17%
Extreme weather
11%
National Airspace System
6%

The largest share of delay minutes, 67%, 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 1,705 of the 2,561 delay minutes reported here. The split is drawn from 2,561 delay minutes reported on OO 5246.

Cancellations are rare at 0.28%, 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 4.6% 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 same number turns up on two other city pairs in the data, including ORD to PIT (11) and FSD to DEN (1), but none flew often enough under OO 5246 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to COS only.

One caution: this is a thin sample. 351 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 5246

For a booking, OO 5246 has one of the better records a US domestic flight can show: 85.1% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
