Every carrier on SFO to OGG, 1,703 flights
These figures cover 1,313 flights between September 2025 and August 2026. The median arrival is 14 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.

Carrier by carrier
United against every carrier on SFO to OGG
United flew 1,313 of the 1,703 flights on SFO to OGG, most of the route. Its 87.5% on time is about level with the route as a whole at 86.8%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from United at 87.5% to Hawaiian at 81.0%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When United runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 12 points, against half a point between the best and worst carrier.
- 5am–8am26 flights—
- 8am–11am499 flights89.9%
- 11am–2pm216 flights92.5%
- 2pm–5pm354 flights80.6%
- 5pm–8pm218 flights87.6%
- 8pm–5am—
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 92.5% on time, ahead of 2pm–5pm at 80.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 8am–11am window is the busiest, with 499 flights scheduled in it.
Across the year
United on SFO to OGG through the year
February is the weak month at 75.0% on time, against 96.8% in October. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 159 flights.
Across the week, Tuesday is the strongest day at 89.2% on time and Friday the weakest at 84.1%, a spread of 5 points.

Worst days for United on SFO to OGG
The latest arrival of the period was on 18 July 2026, 5 hours 21 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 |
|---|---|---|
| 18 July 2026 | 5 hours 21 minutes | Late-arriving aircraft |
| 28 May 2026 | 2 hours 50 minutes | Late-arriving aircraft |
| 16 March 2026 | 2 hours 47 minutes | Carrier |
| 20 April 2026 | 2 hours 47 minutes | Late-arriving aircraft |

Delay causes
Why United runs late on this route
Late-arriving aircraft accounts for 51% of the 7,255 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 28%Carrier
- 21%National Airspace System
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,255 reported delay minutes here, that single category outweighs weather by 51 to one. The split is drawn from 7,255 reported delay minutes.
Cancellations are rare at 0.46%, 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 stage length
What a delay here costs
Badly late arrivals are rare here: only 2.5% 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 2,338 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 return leg is a different operation and performs like one: it runs 90.9% on time across 1,313 flights, 3 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 3 points of difference.
The sample behind these figures is 1,313 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking United on SFO to OGG
Put together: the calendar is the biggest lever here, not the carrier or the hour. October runs 96.8% on time and February 75.0%, a swing of 22 points. If the dates move at all, move them out of February before you think about anything else. 1,305 completed flights over 12 months sit behind that.
