A+GRADE

This route earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 1,670 OGG to SFO flights, with a median arrival 11 minutes early.

Best time to fly OGG to SFO: a 5am–8am departure, ideally on a Monday. Flights in that window arrived on time 95.7% of the time and Monday flights 91.7%, against 90.0% for the route overall.

Set against the rest of the country, this route's record is 12 points better than the US average of 77.6%. That gap is worth roughly 124 fewer late arrivals for every thousand flights.

These figures cover 1,670 flights between July 2025 and June 2026. The median arrival is 11 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

Flights on OGG to SFO

The flight numbers below flew this route at least 250 times in the period, busiest first. Each has its own record, with its schedule and delay causes.

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 14 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–11am251 flights91.2%
  • 11am–2pm489 flights87.8%
  • 2pm–5pm293 flights81.5%
  • 5pm–8pm
  • 8pm–5am429 flights95.1%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 95.7% of the time, against 81.5% for the afternoon window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 489 flights scheduled in it.

Twelve months, one bar each, drawn from the same 1,670 flights. The strip shows how much of this route's record is set by the calendar rather than by the operation.

Darker means more delays. Figures are on-time percentages.September best, February worst

February is the weak month at 85.4% on time, against 95.8% in September. 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 181 flights.

The day of the week is close to irrelevant here: 3 points separates the best day from the worst. Weekly demand peaks are not what drives the delays on this operation.

Delay causes

Why this route gets delayed

One category carries most of the weight here. Carrier accounts for 53% of the 11,000 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.

  • Carrier
    53%
  • Late-arriving aircraft
    27%
  • National Airspace System
    19%
  • Extreme weather
    2%
  • Security
    0%

The largest share of delay minutes, 53%, 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 5,781 of the 11,000 delay minutes reported here. The split is drawn from 10,919 reported delay minutes.

Cancellations are rare at 0.72%, 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 actually costs

Badly late arrivals are rare here: only 2.5% 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 88.7% on time across 1,670 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 1,670 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: take the 5am–8am departure, avoid February if the dates are flexible, and if two carriers are within a few dollars of each other, United is the one with the record behind it. None of that guarantees an on-time arrival; it moves the odds by 14 points, which is the most any booking decision can do. 1,655 completed flights over 12 months sit behind that.

Common questions

OGG to SFO questions

How often is OGG to SFO delayed?

About one flight in ten arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 10.0% of the 1,670 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.

How reliable is OGG to SFO compared with the rest of the country?

90.0% of flights arrive on time here against a national 77.6%, a difference of 12 points in its favour. That is worth a A+ on this site's grading scale.

What time of day has the fewest delays on OGG to SFO?

The 5am–8am departure window is the strongest at 95.7% on time. The 2pm–5pm window is the weakest at 81.5%, 14 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 February delays on OGG to SFO?

February is the weakest month at 85.4% on time, compared with 95.8% in September. Across the year that is 10 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
