UA 1806 lands a B+, 4 points 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 an hour and a half on average. That is a workable record, not a spotless one. That rests on 252 flights, with a median arrival 7 minutes early.

These figures cover 252 flights between July 2025 and June 2026. The median arrival is 7 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 1806 flies

UA 1806 flies HNL to DEN without a single fixed slot. Its most common scheduled departure was 21:40, used on 146 of 252 flights, with 22:50 (46 flights) and 21:35 (30 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 21:40 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and UA 1806 runs 11 points better at 81.1%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

UA 1806 quarter by quarter

Quarter by quarter UA 1806 held fairly steady: 79.3% in Jul–Sep 2025, 86.0% in Oct–Dec 2025, 77.6% in Jan–Mar 2026 and 82.2% 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 202560 flights79.3%
Oct–Dec 202543 flights86.0%
Jan–Mar 202658 flights77.6%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1806 did best on Sunday at 87.9% on time and worst on Wednesday at 75.0%. Each day rests on about 36 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1806 runs late

One category carries most of the weight here. Carrier accounts for 56% of the 4,049 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.

Carrier
56%
Late-arriving aircraft
38%
National Airspace System
7%

38% 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 4,049 reported delay minutes here, that single category outweighs weather by 38 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 4,049 delay minutes reported on UA 1806.

Cancellations are rare at 0.79%, 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

6.0% 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 an hour and a half, 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 seven other city pairs in the data, including DFW to EWR (32), ORD to OMA (32) and BOS to EWR (20), but none flew often enough under UA 1806 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to HNL to DEN only.

One caution: this is a thin sample. 252 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 1806

For a booking, read UA 1806 as 81.1% on time with 0.79% cancelled over 252 flights. Those are rates from the past twelve months, not a forecast for any particular day.
