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 2026 at 60.7%, a swing of 16 points on roughly 66 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.

Scale runs 50% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1805 did best on Wednesday at 82.4% on time and worst on Saturday at 60.9%. Each day rests on about 38 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

13 of 60 late departures made up the time and arrived on time, 22% of them. In the other direction, 24 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.

Delay causes

Why UA 1805 runs late

Carrier accounts for 42% of the 5,248 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    42%
  • Late-arriving aircraft
    32%
  • National Airspace System

  • Extreme weather
    4%

The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,208 of the 5,248 delay minutes reported here. The split is drawn from 5,248 delay minutes reported on UA 1805.

Cancellations are rare at 0.76%, 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

9.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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 LAX to BWI (32), DEN to DFW (32) and CLT to EWR (21), 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. 263 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
