Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5270, 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 5270 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 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 323 flights, with a median arrival 9 minutes early.
Set against the rest of the country, OO 5270's record is 7 points better than the US average of 77.6%. That gap is worth roughly 74 fewer late arrivals for every thousand flights.

These figures cover 323 flights between July 2025 and June 2026. The median arrival is 9 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 5270 flies
OO 5270 flies DEN to MAF without a single fixed slot. Its most common scheduled departure was 13:40, used on 88 of 323 flights, with 13:45 (66 flights) and 13:30 (50 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 13:4088 flights27.2%
- Departs 13:4566 flights20.4%
- Departs 13:3050 flights15.5%
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 13:40 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5270 runs 6 points better at 85.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
OO 5270 quarter by quarter
Quarter by quarter OO 5270 held fairly steady: 83.7% in Jul–Sep 2025, 82.8% in Oct–Dec 2025, 87.1% in Jan–Mar 2026 and 87.5% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights83.7%
- Oct–Dec 202589 flights82.8%
- Jan–Mar 202686 flights87.1%
- Apr–Jun 202656 flights87.5%
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, OO 5270 did best on Saturday at 91.7% on time and worst on Friday at 78.7%. Each day rests on about 46 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 5270 runs late
One category carries most of the weight here. Carrier accounts for 45% of the 3,081 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.
- 45%Carrier
- 37%Late-arriving aircraft
- 10%National Airspace System
- 7%Extreme weather
37% 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 3,081 reported delay minutes here, that single category outweighs weather by 5 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 3,081 delay minutes reported on OO 5270.
Cancellations are rare at 0.62%, 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
5.9% 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 four other city pairs in the data, including IAH to LIT (29), ABQ to DEN (4) and DEN to OMA (3), but none flew often enough under OO 5270 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. 323 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 5270
For a booking, OO 5270 has one of the better records a US domestic flight can show: 85.0% on time and 0.62% cancelled. That is a base rate, not a promise about any single day.
