Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5795, 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 5795 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 an hour on average. That is a workable record, not a spotless one. That rests on 344 flights, with a median arrival 3 minutes early.

These figures cover 344 flights between July 2025 and June 2026. The median arrival is 3 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When OO 5795 flies

OO 5795 flies ORD to TUL without a single fixed slot. Its most common scheduled departure was 08:45, used on 227 of 344 flights, with 08:59 (68 flights) and 09:00 (49 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 08:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5795 runs 7 points worse at 77.3%. 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 5795 quarter by quarter

OO 5795 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.7% on time and its weakest Oct–Dec 2025 at 72.2%, a swing of 12 points on roughly 86 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 5795 did best on Thursday at 85.4% on time and worst on Saturday at 66.0%. Each day rests on about 49 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5795 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 4,913 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
    44%
  • Late-arriving aircraft
    24%
  • National Airspace System
    21%
  • Extreme weather
    11%

The largest share of delay minutes, 44%, 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 2,147 of the 4,913 delay minutes reported here. The split is drawn from 4,913 delay minutes reported on OO 5795.

Cancellations are rare at 0.29%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

6.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The 585 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 344 flights under OO 5795 in the data flew ORD to TUL. 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. 344 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
