Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5675, 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 5675 earns an F−, which is as low as this site's scale goes for a reason. Only 48.2% of flights arrive inside the 15-minute window, 29 points worse than the national rate of 77.6%. Late arrivals average an hour and a half. Treat any tight connection here as a coin flip. That rests on 351 flights, with a median arrival 16 minutes late.

The national on-time rate over the same period is 77.6%, so OO 5675 runs 29 points behind the country as a whole. Across a thousand flights that is about 294 extra late arrivals.

These figures cover 351 flights between July 2025 and June 2026. Beyond the headline rate, 21.1% 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 5675 flies

OO 5675 flies SBN to ORD without a single fixed slot. Its most common scheduled departure was 16:41, used on 76 of 351 flights, with 16:55 (65 flights) and 16:53 (64 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 16:41 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 5675 runs 24 points worse at 48.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5675 quarter by quarter

OO 5675 did not run the same all year. Its best quarter was Jan–Mar 2026 at 55.4% on time and its weakest Jul–Sep 2025 at 37.9%, a swing of 18 points on roughly 88 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.

Jul–Sep 202590 flights37.9%
Oct–Dec 202586 flights48.2%
Jan–Mar 202690 flights55.4%
Apr–Jun 202685 flights51.9%

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

By weekday, OO 5675 did best on Monday at 60.9% on time and worst on Sunday at 34.0%. Each day rests on about 50 flights, so a gap of 27 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5675 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 15,000 reported delay minutes.

Late-arriving aircraft
41%
National Airspace System
34%
Carrier
16%
Extreme weather
8%

41% 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 5 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 14,968 delay minutes reported on OO 5675.

Cancellations run at 5.41%, 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. 21.1% 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 351 flights under OO 5675 in the data flew SBN 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. 351 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 5675

For a booking, the cancellation rate is the figure to plan around on OO 5675: 5.41% of its 351 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
