Historical statistics for July 2025 to June 2026, not live status. For today’s UA 384, check with United Airlines.

UA 384 lands a B+, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 4 minutes early.

These figures cover 365 flights between July 2025 and June 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.

Schedule

When UA 384 flies

UA 384 flies DEN to HNL without a single fixed slot. Its most common scheduled departure was 12:05, used on 153 of 365 flights, with 12:00 (94 flights) and 11:55 (80 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 12:05 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 384 runs level with that at 79.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 384 quarter by quarter

UA 384 did not run the same all year. Its best quarter was Oct–Dec 2025 at 88.0% on time and its weakest Jul–Sep 2025 at 73.0%, a swing of 15 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jul–Sep 202592 flights73.0%
Oct–Dec 202592 flights88.0%
Jan–Mar 202690 flights74.4%
Apr–Jun 202691 flights80.2%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, UA 384 ranged from 74.5% on Thursday to 84.6% on Monday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 384 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 5,664 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 5,664 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 5,664 delay minutes reported on UA 384.

Cancellations are rare at 0.27%, 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

6.4% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 (6), 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 79.0% on time with 0.27% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
