These figures cover 365 flights between July 2025 and June 2026. The median arrival is 13 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 UA 2372 flies

UA 2372 flies KOA to LAX without a single fixed slot. Its most common scheduled departure was 13:15, used on 70 of 365 flights, with 14:20 (67 flights) and 13:05 (56 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 13:15 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 2372 runs 12 points better at 91.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 2372 quarter by quarter

Quarter by quarter UA 2372 held fairly steady: 95.6% in Jul–Sep 2025, 93.5% in Oct–Dec 2025, 87.6% in Jan–Mar 2026 and 87.9% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights95.6%
Oct–Dec 202592 flights93.5%
Jan–Mar 202690 flights87.6%
Apr–Jun 202691 flights87.9%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, UA 2372 did best on Tuesday at 98.1% on time and worst on Sunday at 82.4%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2372 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 56% of the 1,648 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.

Late-arriving aircraft
56%
National Airspace System
28%
Carrier
16%

56% 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 1,648 reported delay minutes here, that single category outweighs weather by 56 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 1,648 delay minutes reported on UA 2372.

Cancellations are rare at 0.55%, 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

Badly late arrivals are rare here: only 2.2% 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 2,504 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on five other city pairs in the data, including LAX to IAH (53), LAX to PHX (48) and LAX to ORD (37), but none flew often enough under UA 2372 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to KOA to LAX only.

One caution: this is a thin sample. 365 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 UA 2372

For a booking, UA 2372 has one of the better records a US domestic flight can show: 91.2% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
