Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4962, 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 4962 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 6 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 316 flights, with a median arrival 10 minutes early.

Set against the rest of the country, OO 4962's record is 6 points better than the US average of 77.6%. That gap is worth roughly 64 fewer late arrivals for every thousand flights.

These figures cover 316 flights between July 2025 and June 2026. Beyond the headline rate, 8.7% 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 4962 flies

OO 4962 flies LAX to SAT without a single fixed slot. Its most common scheduled departure was 18:21, used on 41 of 316 flights, with 18:19 (39 flights) and 17:00 (35 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 18:21 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 4962 runs 16 points better at 84.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

By weekday, OO 4962 did best on Friday at 93.3% on time and worst on Saturday at 72.3%. Each day rests on about 45 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4962 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 3,671 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
62%
Late-arriving aircraft
26%
National Airspace System
8%
Extreme weather
4%

The largest share of delay minutes, 62%, 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 2,278 of the 3,671 delay minutes reported here. The split is drawn from 3,671 delay minutes reported on OO 4962.

Cancellations are rare at 0.63%, 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

8.7% 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 a little over an hour, which a normal layover absorbs.

The 1,211 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 one other city pair in the data, including FNT to ORD (32), but none flew often enough under OO 4962 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to SAT only.

One caution: this is a thin sample. 316 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.
