Every carrier on LAX to RNO, 2,494 flights

These figures cover 114 flights between July 2025 and June 2026. The median arrival is 11 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 LAX to RNO

United flew 114 of the 2,494 flights on LAX to RNO, about 5% of it. Its 89.5% on time is about level with the route as a whole at 88.1%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from SkyWest at 90.8% to Southwest at 71.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

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 114 flights.

There are not enough flights in each departure window to split United's LAX to RNO record by time of day without the percentages moving on noise. The headline rate of 89.5% is the reliable figure here.

Across the year

United on LAX to RNO through the year

Jan–Mar 202627 flights—
Apr–Jun 202687 flights87.4%

Scale runs 80% to 95%. 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 89.5% on time across 114 flights.

Split by quarter, United on LAX to RNO logged 27 flights in Jan–Mar 2026 and 87 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 89.5% annual figure is the one to use.

Delay causes

Why United runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 545 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.

52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 545 reported delay minutes here, that single category outweighs weather by 52 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 545 reported delay minutes.

The largest share of delay minutes, 43%, 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 232 of the 545 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 2.6% 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 390 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 2pm–5pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 86.0% on time across 114 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. 114 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 LAX to RNO

Put together: treat all of this as provisional. 114 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 89.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 114 completed flights over 12 months sit behind that.
