Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5801, 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 5801 lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 324 flights, with a median arrival 3 minutes early.

These figures cover 324 flights between July 2025 and June 2026. Beyond the headline rate, 11.8% 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 5801 flies

OO 5801 flies CRW to ORD without a single fixed slot. Its most common scheduled departure was 07:00, used on 193 of 324 flights, with 06:45 (95 flights) and 06:50 (36 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5801 runs 13 points worse at 76.8%. 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 5801 quarter by quarter

OO 5801 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.0% on time and its weakest Jan–Mar 2026 at 67.1%, a swing of 23 points on roughly 81 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 202555 flights72.7%
Jan–Mar 202686 flights67.1%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5801 did best on Thursday at 83.0% on time and worst on Friday at 69.6%. Each day rests on about 46 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5801 runs late

One category carries most of the weight here. Carrier accounts for 69% of the 8,476 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
69%
National Airspace System
16%
Late-arriving aircraft
13%
Extreme weather
2%

The largest share of delay minutes, 69%, 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 5,848 of the 8,476 delay minutes reported here. The split is drawn from 8,476 delay minutes reported on OO 5801.

Cancellations sit at 2.16% against a national 1.81%, which is ordinary. Diversions add another 0.93%.

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. 11.8% 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 one other city pair in the data, including BIS to DEN (2), but none flew often enough under OO 5801 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CRW to ORD only.

One caution: this is a thin sample. 324 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.
