Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5015, 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 5015 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 253 flights, with a median arrival 6 minutes early.

These figures cover 253 flights between July 2025 and June 2026. Beyond the headline rate, 9.2% 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 5015 flies

OO 5015 flies DEN to JLN without a single fixed slot. Its most common scheduled departure was 14:10, used on 102 of 253 flights, with 20:40 (45 flights) and 20:50 (39 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 14:10 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 5015 runs 8 points better at 80.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5015 quarter by quarter

OO 5015 did not run the same all year. Its best quarter was Oct–Dec 2025 at 85.5% on time and its weakest Jul–Sep 2025 at 74.7%, a swing of 11 points on roughly 63 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.

Oct–Dec 202577 flights85.5%
Jan–Mar 202648 flights81.2%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5015 did best on Tuesday at 87.5% on time and worst on Friday at 70.3%. Each day rests on about 36 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5015 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,318 reported delay minutes.

Extreme weather
40%
Carrier
32%
Late-arriving aircraft
20%
National Airspace System
9%

Extreme weather accounts for 40% 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 6.4 times the usual weather exposure. The split is drawn from 4,318 delay minutes reported on OO 5015.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

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. 9.2% 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.

The 582 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 six other city pairs in the data, including JLN to DEN (45), ATY to DEN (38) and DEN to SGU (17), but none flew often enough under OO 5015 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to JLN only.

One caution: this is a thin sample. 253 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.
