Historical statistics for July 2025 to June 2026, not live status. For today’s OO 6336, 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 6336 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 305 flights, with a median arrival 7 minutes early.

Set against the rest of the country, OO 6336's record is 9 points better than the US average of 77.6%. That gap is worth roughly 92 fewer late arrivals for every thousand flights.

These figures cover 305 flights between July 2025 and June 2026. The median arrival is 7 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 6336 flies

OO 6336 flies TUL to LAX without a single fixed slot. Its most common scheduled departure was 15:35, used on 54 of 305 flights, with 15:13 (51 flights) and 15:25 (45 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 15:35 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 6336 runs 14 points better at 86.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 6336 quarter by quarter

OO 6336 did not run the same all year. Its best quarter was Oct–Dec 2025 at 92.3% on time and its weakest Jan–Mar 2026 at 82.1%, a swing of 10 points on roughly 76 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 6336 did best on Monday at 90.7% on time and worst on Tuesday at 77.8%. Each day rests on about 44 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 6336 runs late

One category carries most of the weight here. Carrier accounts for 77% of the 3,340 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
77%
Late-arriving aircraft
12%
National Airspace System
7%
Extreme weather
4%

The largest share of delay minutes, 77%, 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 2,559 of the 3,340 delay minutes reported here. The split is drawn from 3,340 delay minutes reported on OO 6336.

Cancellations are rare at 0.33%, 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

5.3% 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 1,283 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 four other city pairs in the data, including SFO to LAX (41), LAX to SFO (41) and PHX to ICT (19), but none flew often enough under OO 6336 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to TUL to LAX only.

One caution: this is a thin sample. 305 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 6336

For a booking, OO 6336 has one of the better records a US domestic flight can show: 86.8% on time and 0.33% cancelled. That is a base rate, not a promise about any single day.
