Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5884, 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 5884 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 319 flights, with a median arrival right on schedule.

The national on-time rate over the same period is 77.6%, so OO 5884 runs 5 points behind the country as a whole. Across a thousand flights that is about 51 extra late arrivals.

These figures cover 319 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Schedule

When OO 5884 flies

OO 5884 flies RAP to DEN without a single fixed slot. Its most common scheduled departure was 08:30, used on 126 of 319 flights, with 08:47 (49 flights) and 09:00 (40 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 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5884 runs 12 points worse at 72.5%. 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 5884 quarter by quarter

OO 5884 did not run the same all year. Its best quarter was Oct–Dec 2025 at 84.0% on time and its weakest Jul–Sep 2025 at 69.2%, a swing of 15 points on roughly 80 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.

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5884 did best on Sunday at 82.2% on time and worst on Tuesday at 66.7%. Each day rests on about 46 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5884 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 5,670 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
62%
National Airspace System
16%
Extreme weather
13%
Late-arriving aircraft
8%

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 2.1 times the usual weather exposure. The split is drawn from 5,670 delay minutes reported on OO 5884.

Cancellations are rare at 0.63%, 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.

The same number turns up on one other city pair in the data, including ICT to IAH (2), but none flew often enough under OO 5884 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RAP to DEN only.

One caution: this is a thin sample. 319 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 5884

For a booking, OO 5884 is one of the weaker ways to fly RAP to DEN: 7 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
