Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4741, 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 4741 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 324 flights, with a median arrival 8 minutes early.
Set against the rest of the country, OO 4741's record is 9 points better than the US average of 77.6%. That gap is worth roughly 87 fewer late arrivals for every thousand flights.

These figures cover 324 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 4741 flies
OO 4741 flies LEX to DEN without a single fixed slot. Its most common scheduled departure was 09:00, used on 95 of 324 flights, with 09:26 (49 flights) and 09:20 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 09:0095 flights29.3%
- Departs 09:2649 flights15.1%
- Departs 09:2037 flights11.4%
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 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 4741 runs 2 points better at 86.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes
Why OO 4741 runs late
One category carries most of the weight here. Carrier accounts for 82% of the 3,699 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.
- 82%Carrier
- 13%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 82%, 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 3,040 of the 3,699 delay minutes reported here. The split is drawn from 3,699 delay minutes reported on OO 4741.
Cancellations are rare at 0.62%, 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
5.0% 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 an hour and a half, which a normal layover absorbs.
The 1,086 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 two other city pairs in the data, including ORD to CRW (24) and CVG to ORD (10), but none flew often enough under OO 4741 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LEX to DEN only.
One caution: this is a thin sample. 324 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 4741
For a booking, OO 4741 has one of the better records a US domestic flight can show: 86.3% on time and 0.62% cancelled. That is a base rate, not a promise about any single day.
