Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5352, 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 5352 earns a D−, which is as low as this site's scale goes for a reason. Only 57.7% of flights arrive inside the 15-minute window, 20 points worse than the national rate of 77.6%. Late arrivals average close to two hours. Treat any tight connection here as a coin flip. That rests on 328 flights, with a median arrival 7 minutes late.

The national on-time rate over the same period is 77.6%, so OO 5352 runs 20 points behind the country as a whole. Across a thousand flights that is about 199 extra late arrivals.

These figures cover 328 flights between July 2025 and June 2026. Beyond the headline rate, 23.1% 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 5352 flies

OO 5352 flies ORD to CAK without a single fixed slot. Its most common scheduled departure was 17:50, used on 119 of 328 flights, with 18:05 (48 flights) and 17:45 (45 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 17:50 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 5352 runs 11 points worse at 57.7%. 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 5352 quarter by quarter

OO 5352 did not run the same all year. Its best quarter was Jul–Sep 2025 at 68.2% on time and its weakest Jan–Mar 2026 at 49.4%, a swing of 19 points on roughly 82 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.

Scale runs 40% to 75%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5352 did best on Saturday at 70.5% on time and worst on Sunday at 45.7%. Each day rests on about 47 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5352 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 54% of the 15,000 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.

Extreme weather
3%

54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 15,000 reported delay minutes here, that single category outweighs weather by 20 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 14,855 delay minutes reported on OO 5352.

Cancellations run at 4.57%, against 1.81% nationally. That is roughly 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. 23.1% 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 three other city pairs in the data, including SBN to ORD (41), SUN to DEN (18) and OMA to IAH (11), but none flew often enough under OO 5352 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. 328 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 5352

For a booking, the cancellation rate is the figure to plan around on OO 5352: 4.57% of its 328 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
