Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5791, 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 5791 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about 2.5 hours on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 14 minutes early.

Set against the rest of the country, OO 5791's record is 6 points better than the US average of 77.6%. That gap is worth roughly 63 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When OO 5791 flies

OO 5791 is scheduled to leave Lubbock (LBB) at 08:00 local time and reach Denver (DEN) at 08:52. That slot held for 329 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.

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 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5791 runs level with that at 83.9%. 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 5791 quarter by quarter

Quarter by quarter OO 5791 held fairly steady: 83.7% in Jul–Sep 2025, 85.9% in Oct–Dec 2025, 83.7% in Jan–Mar 2026 and 82.4% 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.

Jul–Sep 202592 flights83.7%
Oct–Dec 202592 flights85.9%
Jan–Mar 202690 flights83.7%

By weekday, OO 5791 did best on Friday at 96.2% on time and worst on Monday at 68.6%. Each day rests on about 52 flights, so a gap of 28 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5791 runs late

One category carries most of the weight here. Carrier accounts for 80% of the 8,765 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
80%
Late-arriving aircraft
14%
National Airspace System
4%
Extreme weather
2%

The largest share of delay minutes, 80%, 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 6,978 of the 8,765 delay minutes reported here. The split is drawn from 8,765 delay minutes reported on OO 5791.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

Every one of the 365 flights under OO 5791 in the data flew LBB to DEN. 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.
