Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5020, 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 5020 lands a B−, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 2.5 hours on average. That is a workable record, not a spotless one. That rests on 334 flights, with a median arrival 6 minutes early.

These figures cover 334 flights between July 2025 and June 2026. Beyond the headline rate, 12.1% 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 5020 flies

OO 5020 flies JLN to ORD without a single fixed slot. Its most common scheduled departure was 08:54, used on 86 of 334 flights, with 08:05 (86 flights) and 07:45 (37 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 08:54 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5020 runs 5 points worse at 79.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OO 5020 quarter by quarter

Quarter by quarter OO 5020 held fairly steady: 82.9% in Jul–Sep 2025, 77.4% in Oct–Dec 2025, 77.9% in Jan–Mar 2026 and 78.0% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202586 flights82.9%
Oct–Dec 202567 flights77.4%
Jan–Mar 202690 flights77.9%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5020 ranged from 75.6% on Sunday to 86.0% on Saturday. With about 48 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 5020 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 9,999 reported delay minutes.

Carrier
41%
National Airspace System
29%
Late-arriving aircraft
17%
Extreme weather
13%

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 9,999 delay minutes reported on OO 5020.

Cancellations run at 3.59%, against 1.81% nationally. That is about 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. 12.1% 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.

The same number turns up on three other city pairs in the data, including ORD to CMX (77), DEN to ATY (31) and ORD to CIU (5), but none flew often enough under OO 5020 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JLN to ORD only.

One caution: this is a thin sample. 334 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 5020

For a booking, the cancellation rate is the figure to plan around on OO 5020: 3.59% of its 334 scheduled flights did not operate. A late arrival costs about 2.5 hours, but a cancellation costs the day, so leave a later option open.
