Every carrier on FAT to LAX, 979 flights

These figures cover 138 flights between July 2025 and June 2026. The median arrival is 5 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.

Carrier by carrier

United against every carrier on FAT to LAX

United flew 138 of the 979 flights on FAT to LAX, about 14% of it. Its 87.7% on time is about level with the route as a whole at 86.4%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from United at 87.7% to SkyWest at 86.2%.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When United runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 138 flights.

There are not enough flights in each departure window to split United's FAT to LAX record by time of day without the percentages moving on noise. The headline rate of 87.7% is the reliable figure here.

Across the year

United on FAT to LAX through the year

Jan–Mar 202648 flights93.8%
Apr–Jun 202690 flights84.4%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 87.7% on time across 138 flights.

Split by quarter, United on FAT to LAX logged 48 flights in Jan–Mar 2026 and 90 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 87.7% annual figure is the one to use.

Delay causes

Why United runs late on this route

One category carries most of the weight here. Carrier accounts for 55% of the 801 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
55%
National Airspace System
45%

45% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 361 minutes out of 801, against a national NAS share of 21%. The split is drawn from 801 reported delay minutes.

The largest share of delay minutes, 55%, 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 440 of the 801 delay minutes reported here.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 3.6% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 209 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 84.1% on time across 138 flights, 4 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.

One caution: this is a thin sample. 138 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 United on FAT to LAX

Put together: treat all of this as provisional. 138 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 87.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 138 completed flights over 12 months sit behind that.
