Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5052, 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 5052 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 about 3.5 hours on average. That is a workable record, not a spotless one. That rests on 313 flights, with a median arrival 13 minutes early.

These figures cover 313 flights between July 2025 and June 2026. Beyond the headline rate, 10.1% 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 5052 flies

OO 5052 is scheduled to leave Denver (DEN) at 21:05 local time and reach Hays (HYS) at 23:22. That slot held for 260 of the 313 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 21:05 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 5052 runs 10 points better at 80.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

OO 5052 quarter by quarter

OO 5052 did not run the same all year. Its best quarter was Oct–Dec 2025 at 91.0% on time and its weakest Jan–Mar 2026 at 72.4%, a swing of 19 points on roughly 78 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.

Jan–Mar 202690 flights72.4%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5052 did best on Tuesday at 92.3% on time and worst on Thursday at 70.5%. Each day rests on about 45 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5052 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 13,000 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.

Late-arriving aircraft
47%
Carrier
38%
Extreme weather
13%
National Airspace System
2%

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 12,759 delay minutes reported on OO 5052.

Cancellations sit at 1.60% against a national 1.81%, which is ordinary. Diversions add another 0.32%.

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. 10.1% 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 same number turns up on six other city pairs in the data, including JLN to DEN (31), LBF to DEN (21) and DEN to LBF (21), but none flew often enough under OO 5052 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to HYS only.

One caution: this is a thin sample. 313 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 5052
