Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5333, 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 5333 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 364 flights, with a median arrival 7 minutes early.

Set against the rest of the country, OO 5333's record is 7 points better than the US average of 77.6%. That gap is worth roughly 71 fewer late arrivals for every thousand flights.

These figures cover 364 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 5333 flies

OO 5333 flies DEN to MAF without a single fixed slot. Its most common scheduled departure was 10:00, used on 103 of 364 flights, with 10:05 (91 flights) and 10:12 (49 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 10:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5333 runs level with that at 84.7%. 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 5333 quarter by quarter

Quarter by quarter OO 5333 held fairly steady: 82.6% in Jul–Sep 2025, 86.4% in Oct–Dec 2025, 84.1% in Jan–Mar 2026 and 85.7% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5333 did best on Tuesday at 90.4% on time and worst on Thursday 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 5333 runs late

One category carries most of the weight here. Carrier accounts for 52% of the 3,625 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
52%
Late-arriving aircraft
44%
National Airspace System
3%
Extreme weather
1%

44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,625 reported delay minutes here, that single category outweighs weather by 35 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,625 delay minutes reported on OO 5333.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

5.3% 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.

The 563 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on one other city pair in the data, including MEM to ORD (1), but none flew often enough under OO 5333 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to MAF only.

One caution: this is a thin sample. 364 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 5333

For a booking, read OO 5333 as 84.7% on time with 1.10% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
