These figures cover 365 flights between September 2025 and August 2026. The median arrival is 4 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.

Across the year
UA 384 quarter by quarter

Share of 364 completed flights by arrival against schedule.
19 of 64 late departures made up the time and arrived on time, 30% of them. In the other direction, 26 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at HNL.
The worst days
Worst days for UA 384
The latest arrival of the period was on 2 November 2025, 7 hours 9 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 November 2025 | 7 hours 9 minutes | Late-arriving aircraft |
| 25 November 2025 | 6 hours 28 minutes | Late-arriving aircraft |
| 22 October 2025 | 6 hours 13 minutes | Late-arriving aircraft |
| 15 March 2026 | 5 hours 40 minutes | Carrier |

Delay causes
Why UA 384 runs late
Carrier accounts for 48% of the 5,494 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 38%Late-arriving aircraft
- 14%National Airspace System
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,494 reported delay minutes here, that single category outweighs weather by 38 to one. The split is drawn from 5,494 delay minutes reported on UA 384.
Cancellations are rare at 0.27%, 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
6.3% of arrivals land an hour or more late, close to the national 8.3%, so 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.
At 3,365 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 one other city pair in the data, including LEX to DEN (47), but none flew often enough under UA 384 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to HNL 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 384
For a booking, read UA 384 as 80.5% on time with 0.27% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
