Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5083, 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 5083 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 2.2 hours behind schedule. That rests on 345 flights, with a median arrival 5 minutes early.

These figures cover 345 flights between July 2025 and June 2026. Beyond the headline rate, 14.5% 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 5083 flies

OO 5083 flies DEN to CYS without a single fixed slot. Its most common scheduled departure was 21:04, used on 202 of 345 flights, with 21:05 (94 flights) and 21:03 (49 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 21:04 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 5083 runs level with that at 72.4%. 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 5083 quarter by quarter

OO 5083 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.8% on time and its weakest Jul–Sep 2025 at 62.1%, a swing of 25 points on roughly 86 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.

By weekday, OO 5083 did best on Saturday at 79.6% on time and worst on Friday at 60.4%. Each day rests on about 49 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5083 runs late

One category carries most of the weight here. Carrier accounts for 45% of the 12,000 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

National Airspace System
14%
Extreme weather
10%

The largest share of delay minutes, 45%, 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 5,563 of the 12,000 delay minutes reported here. The split is drawn from 12,375 delay minutes reported on OO 5083.

Cancellations sit at 1.45% against a national 1.81%, which is ordinary. Diversions add another 0.87%.

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. 14.5% 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 two other city pairs in the data, including LAR to DEN (18) and HYS to DEN (13), but none flew often enough under OO 5083 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to CYS only.

One caution: this is a thin sample. 345 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 5083

For a booking, OO 5083 is a flight to put a long connection behind. 14.5% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
