Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5362, 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 5362 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 343 flights, with a median arrival 1 minute late.

The national on-time rate over the same period is 77.6%, so OO 5362 runs 9 points behind the country as a whole. Across a thousand flights that is about 92 extra late arrivals.

These figures cover 343 flights between July 2025 and June 2026. Beyond the headline rate, 13.6% 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 5362 flies

OO 5362 flies ORD to MKE without a single fixed slot. Its most common scheduled departure was 21:45, used on 60 of 343 flights, with 21:40 (48 flights) and 21:20 (38 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 21:45 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 5362 runs 2 points worse at 68.4%. 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 5362 quarter by quarter

OO 5362 did not run the same all year. Its best quarter was Oct–Dec 2025 at 73.0% on time and its weakest Apr–Jun 2026 at 62.9%, a swing of 10 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 5362 did best on Tuesday at 75.5% on time and worst on Sunday at 63.0%. Each day rests on about 49 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5362 runs late

One category carries most of the weight here. Carrier accounts for 60% of the 8,431 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
16%
Extreme weather
5%

The largest share of delay minutes, 60%, 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 5,033 of the 8,431 delay minutes reported here. The split is drawn from 8,431 delay minutes reported on OO 5362.

Cancellations run at 2.92%, against 1.81% nationally. That is roughly 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. 13.6% 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 one other city pair in the data, including SFO to MCI (19), but none flew often enough under OO 5362 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to MKE only.

One caution: this is a thin sample. 343 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 5362

For a booking, the cancellation rate is the figure to plan around on OO 5362: 2.92% of its 343 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
