These figures cover 365 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year
UA 1947 quarter by 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.

Share of 364 completed flights by arrival against schedule.
A late pushback is often recovered here: of 75 departures that left 15 minutes late or more, 29 still arrived on time. In the other direction, 28 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 SFO.
The worst days
Worst days for UA 1947
The latest arrival of the period was on 24 February 2026, 4 hours 25 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 February 2026 | 4 hours 25 minutes | Late-arriving aircraft |
| 23 February 2026 | 4 hours 17 minutes | Late-arriving aircraft |
| 29 June 2026 | 3 hours 33 minutes | Carrier |
| 3 October 2025 | 2 hours 19 minutes | Late-arriving aircraft |

Delay causes
Why UA 1947 runs late
Late-arriving aircraft accounts for 45% of the 3,279 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 30%Carrier
- 25%National Airspace System
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,279 reported delay minutes here, that single category outweighs weather by 45 to one. The split is drawn from 3,279 delay minutes reported on UA 1947.
Cancellations are rare at 0.27%, 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
Badly late arrivals are rare here: only 3.3% land an hour or more behind schedule, against 8.3% 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 (52), 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 79.7% on time with 0.27% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
