UA 1947 lands a B+, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 2 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 2 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 1947 flies

UA 1947 flies HNL to SFO without a single fixed slot. Its most common scheduled departure was 14:25, used on 64 of 365 flights, with 15:30 (49 flights) and 15:50 (41 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 14:25 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 1947 runs 5 points better at 77.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

UA 1947 next to HNL to SFO

Across the year

UA 1947 quarter by quarter

Quarter by quarter UA 1947 held fairly steady: 80.4% in Jul–Sep 2025, 80.4% in Oct–Dec 2025, 77.8% in Jan–Mar 2026 and 72.5% 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 202592 flights80.4%
Oct–Dec 202592 flights80.4%
Jan–Mar 202690 flights77.8%
Apr–Jun 202691 flights72.5%

Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1947 did best on Tuesday at 88.7% on time and worst on Sunday at 69.2%. Each day rests on about 52 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1947 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 4,218 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.

Late-arriving aircraft
52%
Carrier
27%
National Airspace System
21%

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 4,218 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 4,218 delay minutes reported on UA 1947.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 2,398 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 three other city pairs in the data, including SFO to MCO (31), SFO to ORD (18) and SFO to CMH (3), but none flew often enough under UA 1947 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to HNL to SFO 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 1947

For a booking, read UA 1947 as 77.8% on time with 0.00% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
