Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5565, 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 5565 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 10 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 353 flights, with a median arrival right on schedule.
The national on-time rate over the same period is 77.6%, so OO 5565 runs 10 points behind the country as a whole. Across a thousand flights that is about 95 extra late arrivals.

These figures cover 353 flights between July 2025 and June 2026. Beyond the headline rate, 14.3% 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 5565 flies
OO 5565 flies ORD to CHO without a single fixed slot. Its most common scheduled departure was 13:55, used on 165 of 353 flights, with 14:04 (102 flights) and 14:00 (41 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 13:55 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5565 runs 11 points worse at 68.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Delay causes
Why OO 5565 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 8,511 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.
- 47%Late-arriving aircraft
- 38%Carrier
- 13%National Airspace System
- 2%Extreme weather
47% 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 8,511 reported delay minutes here, that single category outweighs weather by 22 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 8,511 delay minutes reported on OO 5565.
Cancellations run at 3.68%, against 1.81% nationally. That is roughly one flight in 25 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. 14.3% 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.
Every one of the 353 flights under OO 5565 in the data flew ORD to CHO. 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. 353 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 5565
For a booking, the cancellation rate is the figure to plan around on OO 5565: 3.68% of its 353 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.
