These figures cover 1,313 flights between September 2025 and August 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

Book the morning departure. Flights leaving between 8am–11am arrive on time 98.5% of the time, against 81.1% 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 446 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. July was the busiest month here, with 159 flights.
Across the week, Thursday is the strongest day at 93.4% on time and Friday the weakest at 88.3%, a spread of 5 points.

Delay causes
Why United runs late on this route
Carrier accounts for 56% of the 7,479 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 25%National Airspace System
- 19%Late-arriving aircraft
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,184 of the 7,479 delay minutes reported here. The split is drawn from 7,479 reported delay minutes.
Cancellations are rare at 0.84%, 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 1.6% 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 87.5% on time across 1,313 flights, 3 points below 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 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. 1,301 completed flights over 12 months sit behind that.
