Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5358, 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 5358 draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 310 flights, with a median arrival 3 minutes late.

The national on-time rate over the same period is 77.6%, so OO 5358 runs 14 points behind the country as a whole. Across a thousand flights that is about 143 extra late arrivals.

These figures cover 310 flights between July 2025 and June 2026. Beyond the headline rate, 14.6% 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 5358 flies

OO 5358 flies ORD to CAK without a single fixed slot. Its most common scheduled departure was 14:35, used on 101 of 310 flights, with 14:40 (91 flights) and 14:30 (50 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 14:35 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 5358 runs 9 points worse at 63.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5358 quarter by quarter

OO 5358 did not run the same all year. Its best quarter was Jan–Mar 2026 at 68.8% on time and its weakest Apr–Jun 2026 at 51.1%, a swing of 18 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 202684 flights68.8%

Scale runs 45% to 75%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5358 did best on Monday at 73.8% on time and worst on Friday at 41.9%. Each day rests on about 44 flights, so a gap of 32 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5358 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 7,175 reported delay minutes.

Carrier
40%
Late-arriving aircraft
31%
National Airspace System
19%
Extreme weather
10%

The largest share of delay minutes, 40%, 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 2,887 of the 7,175 delay minutes reported here. The split is drawn from 7,175 delay minutes reported on OO 5358.

Cancellations run at 5.16%, against 1.81% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

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. 14.6% 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 four other city pairs in the data, including MSN to ORD (35), ORD to BOI (6) and MCI to DEN (5), but none flew often enough under OO 5358 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CAK only.

One caution: this is a thin sample. 310 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 5358

For a booking, the cancellation rate is the figure to plan around on OO 5358: 5.16% of its 310 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
