Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5392, 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 5392 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 288 flights, with a median arrival 1 minute early.

The national on-time rate over the same period is 77.6%, so OO 5392 runs 9 points behind the country as a whole. Across a thousand flights that is about 85 extra late arrivals.

These figures cover 288 flights between July 2025 and June 2026. Beyond the headline rate, 13.4% 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 5392 flies

OO 5392 flies ORD to OKC without a single fixed slot. Its most common scheduled departure was 19:45, used on 70 of 288 flights, with 19:46 (63 flights) and 19:36 (48 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 19:4570 flights24.3%
  • Departs 19:4663 flights21.9%
  • Departs 19:3648 flights16.7%

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 19:45 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 5392 runs level with that at 69.1%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

OO 5392 next to ORD to OKC

Across the year

OO 5392 quarter by quarter

Quarter by quarter OO 5392 held fairly steady: 71.4% in Jul–Sep 2025, 68.3% in Oct–Dec 2025, 69.0% in Jan–Mar 2026 and 67.5% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, OO 5392 did best on Wednesday at 80.0% on time and worst on Sunday at 53.7%. Each day rests on about 41 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5392 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 6,217 reported delay minutes.

  • National Airspace System
    33%
  • Carrier
    29%
  • Late-arriving aircraft
    26%
  • Extreme weather
    12%

Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 6,217 delay minutes reported on OO 5392.

Cancellations run at 5.56%, against 1.81% nationally. That is roughly 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. 13.4% 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 693 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 three other city pairs in the data, including MSN to ORD (30), IAH to MAF (24) and IAH to SAT (2), but none flew often enough under OO 5392 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to OKC only.

One caution: this is a thin sample. 288 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 5392

For a booking, the cancellation rate is the figure to plan around on OO 5392: 5.56% of its 288 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.
