Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5093, 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 5093 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 3.9 hours. That rests on 364 flights, with a median arrival 10 minutes early.

These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 8.3% 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 5093 flies

OO 5093 flies RKS to DEN without a single fixed slot. Its most common scheduled departure was 05:15, used on 237 of 364 flights, with 05:33 (49 flights) and 05:05 (41 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 05:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5093 runs 2 points worse at 87.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why OO 5093 runs late

One category carries most of the weight here. Carrier accounts for 60% of the 11,000 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
60%
Late-arriving aircraft
22%
Extreme weather
13%
National Airspace System
5%

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 10,742 delay minutes reported on OO 5093.

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

8.3% 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 3.9 hours, which a normal layover absorbs.

The same number turns up on two other city pairs in the data, including DEN to BFF (10) and DEN to SHR (6), but none flew often enough under OO 5093 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RKS to DEN 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 5093

For a booking, OO 5093 has one of the better records a US domestic flight can show: 87.3% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
