Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3704, 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 3704 lands a B+, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 320 flights, with a median arrival 11 minutes early.
Set against the rest of the country, OO 3704's record is 5 points better than the US average of 77.6%. That gap is worth roughly 47 fewer late arrivals for every thousand flights.

These figures cover 320 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% 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 3704 flies
OO 3704 flies LAX to ASE without a single fixed slot. Its most common scheduled departure was 14:45, used on 129 of 320 flights, with 09:30 (72 flights) and 09:35 (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 14:45 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 3704 runs 10 points better at 82.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
OO 3704 quarter by quarter
OO 3704 did not run the same all year. Its best quarter was Oct–Dec 2025 at 89.6% on time and its weakest Jan–Mar 2026 at 75.9%, a swing of 14 points on roughly 80 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.

- Oct–Dec 202579 flights89.6%
- Jan–Mar 202686 flights75.9%

By weekday, OO 3704 did best on Wednesday at 88.6% on time and worst on Monday at 76.1%. Each day rests on about 46 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 3704 runs late
One category carries most of the weight here. Carrier accounts for 76% of the 6,010 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.
- 76%Carrier
- 14%National Airspace System
- 10%Extreme weather
The largest share of delay minutes, 76%, 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 4,590 of the 6,010 delay minutes reported here. The split is drawn from 6,010 delay minutes reported on OO 3704.
Cancellations are rare at 0.31%, 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
8.4% 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 close to two hours, which a normal layover absorbs.
The 737 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 BZN to LAX (16) and LAX to BZN (16), but none flew often enough under OO 3704 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to ASE only.
One caution: this is a thin sample. 320 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 3704
