UA 1805 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 8 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 252 flights, with a median arrival 1 minute early.

These figures cover 252 flights between July 2025 and June 2026. Beyond the headline rate, 12.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When UA 1805 flies

UA 1805 flies DEN to HNL without a single fixed slot. Its most common scheduled departure was 16:25, used on 75 of 252 flights, with 16:00 (75 flights) and 16:30 (32 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 16:25 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 1805 runs 3 points worse at 69.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 1805 quarter by quarter

UA 1805 did not run the same all year. Its best quarter was Oct–Dec 2025 at 76.7% on time and its weakest Jul–Sep 2025 at 52.8%, a swing of 24 points on roughly 63 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 202560 flights52.8%
Oct–Dec 202543 flights76.7%
Jan–Mar 202658 flights75.0%
Apr–Jun 202691 flights73.3%

Scale runs 45% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1805 did best on Wednesday at 76.7% on time and worst on Saturday at 64.6%. Each day rests on about 36 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1805 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,656 reported delay minutes.

Late-arriving aircraft
40%
Carrier
37%
National Airspace System
19%
Extreme weather
4%

40% 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 5,656 reported delay minutes here, that single category outweighs weather by 10 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 5,656 delay minutes reported on UA 1805.

Cancellations sit at 1.19% against a national 1.81%, which is ordinary. Diversions add another 2.78%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

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 four other city pairs in the data, including CLT to EWR (32), LAX to BWI (32) and DEN to DFW (32), but none flew often enough under UA 1805 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. 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 1805

For a booking, UA 1805 is a flight to put a long connection behind. 12.0% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
