Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5407, 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 5407 lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about 2.4 hours on average. That is a workable record, not a spotless one. That rests on 269 flights, with a median arrival 5 minutes early.

These figures cover 269 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 5407 flies

OO 5407 flies CHO to ORD without a single fixed slot. Its most common scheduled departure was 07:00, used on 133 of 269 flights, with 06:45 (45 flights) and 07:01 (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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5407 runs 12 points worse at 77.1%. 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 5407 quarter by quarter

OO 5407 did not run the same all year. Its best quarter was Jul–Sep 2025 at 86.7% on time and its weakest Jan–Mar 2026 at 69.1%, a swing of 18 points on roughly 90 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 5407 did best on Thursday at 89.7% on time and worst on Friday at 64.9%. Each day rests on about 38 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5407 runs late

One category carries most of the weight here. Carrier accounts for 83% of the 8,603 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.

  • Carrier
    83%
  • Late-arriving aircraft
    10%
  • National Airspace System
    6%
  • Extreme weather
    1%

The largest share of delay minutes, 83%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 7,113 of the 8,603 delay minutes reported here. The split is drawn from 8,603 delay minutes reported on OO 5407.

Cancellations run at 2.97%, against 1.81% nationally. That is roughly 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. 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.

The same number turns up on seven other city pairs in the data, including TUL to ORD (32), ORD to PNS (21) and IAH to JAX (17), but none flew often enough under OO 5407 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CHO to ORD only.

One caution: this is a thin sample. 269 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 5407

For a booking, the cancellation rate is the figure to plan around on OO 5407: 2.97% of its 269 scheduled flights did not operate. A late arrival costs about 2.4 hours, but a cancellation costs the day, so leave a later option open.
