These figures cover 365 flights between September 2025 and August 2026. The median arrival is 14 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.

Worst days for UA 2372
The latest arrival of the period was on 5 January 2026, 3 hours 20 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 January 2026 | 3 hours 20 minutes | Late-arriving aircraft |
| 30 October 2025 | 2 hours 45 minutes | Late-arriving aircraft |
| 19 April 2026 | 1 hour 47 minutes | Late-arriving aircraft |
| 26 December 2025 | 1 hour 39 minutes | Late-arriving aircraft |

Delay causes
Why UA 2372 runs late
Late-arriving aircraft accounts for 57% of the 1,588 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 35%National Airspace System
- 8%Carrier
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,588 reported delay minutes here, that single category outweighs weather by 57 to one. The split is drawn from 1,588 delay minutes reported on UA 2372.
Cancellations are rare at 0.82%, below the national 1.89% 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 1.9% land an hour or more behind schedule, against 8.3% 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 four other city pairs in the data, including LAX to IAH (53), LAX to ORD (37) and LAX to IAD (31), 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: 90.6% on time and 0.82% cancelled. That is a base rate, not a promise about any single day.
