This route earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs about an hour. That rests on 1,703 SFO to OGG flights, with a median arrival 12 minutes early.
Best time to fly SFO to OGG: a 11am–2pm departure, ideally on a Tuesday. Flights in that window arrived on time 92.5% of the time and Tuesday flights 89.0%, against 86.8% for the route overall.
Set against the rest of the country, this route's record is 10 points better than the US average of 77.3%. That gap is worth roughly 95 fewer late arrivals for every thousand flights.

These figures cover 1,703 flights between September 2025 and August 2026. The median arrival is 12 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.

The most reliable ways to fly San Francisco to Kahului
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 1 of the top 2 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. SFO → OGGSan Francisco to Kahului | United Airlines | 87.1% | 87.5% | 0.46% | 11am–2pm, Tue | UA 1749 16:40 |
| 2. OAK → OGGOakland to Kahului | Southwest Airlines | 73.7% | 73.9% | 0.27% | 11am–2pm, Mon | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
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.

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 724 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 19 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
August is the worst month at 76.9% on time, 19 points below December, the best at 95.4%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. July was the busiest month here, with 190 flights.
Across the week, Tuesday is the strongest day at 89.0% on time and Friday the weakest at 83.3%, a spread of 6 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 50% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 35%Carrier
- 14%National Airspace System
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 12,995 reported delay minutes.
The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,589 of the 13,000 delay minutes reported here.
Cancellations are rare at 0.53%, 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 actually 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 2,338 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 90.4% on time across 1,703 flights, 4 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 4 points of difference.
The sample behind these figures is 1,703 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 this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. December runs 95.4% on time and August 76.9%, a swing of 19 points. If the dates move at all, move them out of August before you think about anything else. 1,691 completed flights over 12 months sit behind that.
Common questions
SFO to OGG questions
How often is SFO to OGG delayed?
About one flight in eight arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 13.2% of the 1,703 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is SFO to OGG compared with the rest of the country?
86.8% of flights arrive on time here against a national 77.3%, a difference of 10 points in its favour. That is worth a A+ on this site's grading scale.
What time of day has the fewest delays on SFO to OGG?
The 11am–2pm departure window is the strongest at 92.5% on time. The 2pm–5pm window is the weakest at 80.6%, 12 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are August delays on SFO to OGG?
August is the weakest month at 76.9% on time, compared with 95.4% in December. Across the year that is 19 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
