Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5224, 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 5224 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 7 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 7 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 5224 flies

OO 5224 is scheduled to leave Denver (DEN) at 13:25 local time and reach Durango (DRO) at 14:48. That slot held for 327 of the 365 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 13:25 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5224 runs level with that at 80.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5224 quarter by quarter

OO 5224 did not run the same all year. Its best quarter was Oct–Dec 2025 at 93.3% on time and its weakest Jul–Sep 2025 at 71.7%, a swing of 22 points on roughly 91 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.

Jul–Sep 202592 flights71.7%
Oct–Dec 202592 flights93.3%
Jan–Mar 202690 flights78.7%
Apr–Jun 202691 flights76.9%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5224 did best on Saturday at 90.2% on time and worst on Friday at 73.1%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5224 runs late

One category carries most of the weight here. Carrier accounts for 56% of the 4,551 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
56%
Late-arriving aircraft
28%
National Airspace System
16%
Extreme weather
1%

The largest share of delay minutes, 56%, 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 2,545 of the 4,551 delay minutes reported here. The split is drawn from 4,551 delay minutes reported on OO 5224.

Cancellations are rare at 0.55%, 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

6.6% 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 about an hour, which a normal layover absorbs.

Every one of the 365 flights under OO 5224 in the data flew DEN to DRO. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 365 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 5224
