Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5610, 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 5610 draws a D−. Roughly one flight in two arrives at least 15 minutes late, and the typical late arrival is close to two hours behind schedule. Build slack into anything you connect to. That rests on 357 flights, with a median arrival 4 minutes late.
The national on-time rate over the same period is 77.6%, so OO 5610 runs 19 points behind the country as a whole. Across a thousand flights that is about 190 extra late arrivals.

These figures cover 357 flights between July 2025 and June 2026. Beyond the headline rate, 21.4% 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 5610 flies
OO 5610 flies ORD to CHO without a single fixed slot. Its most common scheduled departure was 17:50, used on 92 of 357 flights, with 17:45 (82 flights) and 18:15 (72 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 5610 runs 10 points worse at 58.6%. 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 5610 quarter by quarter
OO 5610 did not run the same all year. Its best quarter was Oct–Dec 2025 at 63.9% on time and its weakest Jan–Mar 2026 at 50.0%, a swing of 14 points on roughly 89 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 202591 flights57.5%
- Oct–Dec 202589 flights63.9%
- Jan–Mar 202687 flights50.0%
- Apr–Jun 202690 flights62.8%
Scale runs 40% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, OO 5610 ranged from 54.9% on Tuesday to 64.6% on Thursday. With about 51 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why OO 5610 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.
- 39%Carrier
- 38%Late-arriving aircraft
- 14%National Airspace System
- 10%Extreme weather
38% 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 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 14,930 delay minutes reported on OO 5610.
Cancellations run at 5.32%, 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. 21.4% 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 566 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on one other city pair in the data, including STL to IAH (1), but none flew often enough under OO 5610 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CHO only.
One caution: this is a thin sample. 357 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 5610
For a booking, the cancellation rate is the figure to plan around on OO 5610: 5.32% of its 357 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.
