Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5466, 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 5466 earns an F−, which is as low as this site's scale goes for a reason. Only 48.0% of flights arrive inside the 15-minute window, 30 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 321 flights, with a median arrival 16 minutes late.

The national on-time rate over the same period is 77.6%, so OO 5466 runs 30 points behind the country as a whole. Across a thousand flights that is about 296 extra late arrivals.

These figures cover 321 flights between July 2025 and June 2026. Beyond the headline rate, 18.9% 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 5466 flies

OO 5466 flies FWA to ORD without a single fixed slot. Its most common scheduled departure was 18:25, used on 72 of 321 flights, with 18:29 (66 flights) and 18:18 (36 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 18:25 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 5466 runs 20 points worse at 48.0%. 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 5466 quarter by quarter

OO 5466 did not run the same all year. Its best quarter was Apr–Jun 2026 at 65.0% on time and its weakest Oct–Dec 2025 at 40.0%, a swing of 25 points on roughly 80 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 5466 did best on Saturday at 62.8% on time and worst on Friday at 40.4%. Each day rests on about 46 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5466 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 12,000 reported delay minutes.

National Airspace System
39%
Late-arriving aircraft
34%
Carrier
25%
Extreme weather
2%

39% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 4,744 minutes out of 12,000, against a national NAS share of 21%. The split is drawn from 12,026 delay minutes reported on OO 5466.

Cancellations run at 7.79%, against 1.81% nationally. That is about one flight in twelve 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. 18.9% 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 two other city pairs in the data, including SCE to ORD (6) and SFO to MFR (3), but none flew often enough under OO 5466 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to FWA to ORD only.

One caution: this is a thin sample. 321 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 5466

For a booking, the cancellation rate is the figure to plan around on OO 5466: 7.79% of its 321 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.
