When this route gets cheap.

Cached-fare history: across 6 months, Oct is the cheapest for SF → HNL. Best time to be there: Apr–Jun · Sep–Nov.

Fares bottom out in October around $177 and peak in March near $382 — a $205 spread across the 6 months we track. The cheapest itinerary we are tracking flies United nonstop and takes about 6 hours outbound, on a 7-night trip. At $177 for 3,854 km each way, that works out to about $23 per 1,000 km flown. That is well under the $39 that medium-haul fares on this board typically run. It is also the cheapest of the 6 routes of similar length we watch out of San Francisco.

02Good to know

SF → HNL, answered.

Is $177 a good price for San Francisco to Honolulu?

Yes — the seasonal median for this route is around $315 round-trip. At $177 you're 44% below that, saving about $138, which we rate rare for this route.

What is the cheapest month to fly from San Francisco to Honolulu?

Across 6 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Honolulu are Apr–Jun · Sep–Nov — when those overlap, that's your window.

How far in advance should I book SF → Honolulu?

We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 6 months of cached fares, Oct comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.

Are there nonstop flights from San Francisco to Honolulu?

Yes — the current board includes nonstop fares (United). The outbound leg runs around 6 hours.

Are these prices guaranteed?

No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
