Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4752, 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 4752 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land about 2.2 hours behind schedule. That rests on 364 flights, with a median arrival 5 minutes early.

The national on-time rate over the same period is 77.6%, so OO 4752 runs 6 points behind the country as a whole. Across a thousand flights that is about 64 extra late arrivals.

These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 17.1% 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 4752 flies

OO 4752 flies CAK to ORD without a single fixed slot. Its most common scheduled departure was 14:02, used on 78 of 364 flights, with 13:55 (58 flights) and 14:10 (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 14:02 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 4752 runs level with that at 71.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 4752 quarter by quarter

OO 4752 did not run the same all year. Its best quarter was Apr–Jun 2026 at 79.5% on time and its weakest Jan–Mar 2026 at 65.1%, a swing of 14 points on roughly 91 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 55% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, OO 4752 did best on Wednesday at 80.4% on time and worst on Friday at 57.1%. Each day rests on about 52 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4752 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 13,000 reported delay minutes.

Late-arriving aircraft
39%
National Airspace System
31%
Carrier
20%
Extreme weather
10%

39% 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 13,000 reported delay minutes here, that single category outweighs weather by 4 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 13,110 delay minutes reported on OO 4752.

Cancellations run at 3.30%, against 1.81% nationally. That is about one flight in 30 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. 17.1% 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.

Every one of the 364 flights under OO 4752 in the data flew CAK to ORD. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 364 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 4752

For a booking, the cancellation rate is the figure to plan around on OO 4752: 3.30% of its 364 scheduled flights did not operate. A late arrival costs about 2.2 hours, but a cancellation costs the day, so leave a later option open.
