Departure window
When Alaska 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 234 flights.
There are not enough flights in each departure window to split Alaska's LIH to SFO record by time of day without the percentages moving on noise. The headline rate of 71.0% is the reliable figure here.

Delay causes
Why Alaska runs late on this route
Late-arriving aircraft accounts for 80% of the 4,078 delay minutes carriers reported here, and the remaining four split what is left.
- 80%Late-arriving aircraft
- 15%Carrier
- 5%National Airspace System
- 0%Extreme weather
80% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,078 reported delay minutes here, that single category outweighs weather by 80 to one. The split is drawn from 4,078 reported delay minutes.
Cancellations sit at 1.28% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
10.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 2,446 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 90.0% on time across 233 flights, 19 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 19 points of difference.
One caution: this is a thin sample. 234 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 Alaska on LIH to SFO
Put together: treat all of this as provisional. 234 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 71.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 231 completed flights over 12 months sit behind that.
