Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5741, 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 5741 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%.

These figures cover 261 flights between July 2025 and June 2026. The median arrival is 8 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 5741 flies
OO 5741 flies BNA to ORD without a single fixed slot. Its most common scheduled departure was 06:00, used on 111 of 261 flights, with 06:04 (87 flights) and 06:07 (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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5741 runs 2 points worse at 87.1%. 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 5741 quarter by quarter
OO 5741 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.4% on time and its weakest Oct–Dec 2025 at 78.0%, a swing of 15 points on roughly 87 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 5741 did best on Tuesday at 100.0% on time and worst on Monday at 77.1%. Each day rests on about 37 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 5741 runs late
One category carries most of the weight here. Carrier accounts for 72% of the 4,398 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.
- 72%Carrier
- 18%National Airspace System
- 6%Extreme weather
- 4%Late-arriving aircraft
The largest share of delay minutes, 72%, 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 3,188 of the 4,398 delay minutes reported here. The split is drawn from 4,398 delay minutes reported on OO 5741.
Cancellations sit at 1.92% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.0% 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 2.2 hours, which a normal layover absorbs.
The same number turns up on four other city pairs in the data, including ORD to ORF (13), ABE to ORD (11) and MEM to ORD (9), but none flew often enough under OO 5741 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BNA to ORD only.
One caution: this is a thin sample. 261 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 5741
