These figures cover 365 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.

Departure window
When Southwest runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 365 flights.
There are not enough flights in each departure window to split Southwest's OGG to OAK record by time of day without the percentages moving on noise. The headline rate of 95.9% is the reliable figure here.
Across the year
Southwest on OGG to OAK through the year
April is the best month on the calendar at 100.0% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. January was the busiest month here, with 31 flights.
Across the week, Tuesday is the strongest day at 98.1% on time and Thursday the weakest at 92.3%, a spread of 6 points.

Delay causes
Why Southwest runs late on this route
Carrier accounts for 82% of the 723 delay minutes carriers reported here, and the remaining four split what is left.
- 82%Carrier
- 18%National Airspace System
The largest share of delay minutes, 82%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 593 of the 723 delay minutes reported here. The split is drawn from 723 reported delay minutes.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are 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 0.8% 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 2,348 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 73.9% on time across 365 flights, 22 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 22 points of difference.
One caution: this is a thin sample. 365 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking Southwest on OGG to OAK
Put together: treat all of this as provisional. 365 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 95.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 365 completed flights over 12 months sit behind that.
