Every carrier on OGG to SFO, 1,670 flights
These figures cover 1,280 flights between July 2025 and June 2026. The median arrival is 13 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 OGG to SFO
United flew 1,280 of the 1,670 flights on OGG to SFO, most of the route. Its 90.4% on time is about level with the route as a whole at 90.0%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from United at 90.4% to Alaska at 88.2%. 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 17 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am208 flights95.7%
- 8am–11am68 flights98.5%
- 11am–2pm307 flights87.4%
- 2pm–5pm293 flights81.5%
- 5pm–8pm—
- 8pm–5am404 flights95.0%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 98.5% of the time, against 81.5% for the afternoon window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 404 flights scheduled in it.
Across the year
United on OGG to SFO through the year
December is the weak month at 84.6% 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. June was the busiest month here, with 151 flights.
The day of the week is close to irrelevant here: 4 points separates the best day from the worst. Weekly demand peaks are not what drives the delays on this operation.
Delay causes
Why United runs late on this route
One category carries most of the weight here. Carrier accounts for 51% of the 7,902 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.
- 51%Carrier
- 25%National Airspace System
- 24%Late-arriving aircraft
The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 4,051 of the 7,902 delay minutes reported here. The split is drawn from 7,902 reported delay minutes.
Cancellations are rare at 0.78%, below the national 1.81% 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 2.1% 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 2,338 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 runs 89.4% on time across 1,280 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,280 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 OGG to SFO
Put together: the calendar is the biggest lever here, not the carrier or the hour. October runs 96.8% on time and December 84.6%, a swing of 12 points. If the dates move at all, move them out of December before you think about anything else. 1,269 completed flights over 12 months sit behind that.
