San Francisco to Honolulu in Economy

The sharpest number on this route comes from a connecting opportunity rather than the mainline SFO-HNL leg itself. British Airways Avios prices Hawaiian Airlines inter-island flights at just 5,000 Avios off-peak, and those tickets run roughly $130 in cash, producing a redemption value of 2.6¢ per Avios. That beats our 1.5¢ Avios valuation by a wide margin and is worth stacking if your itinerary includes a hop between Honolulu, Maui, Kauai, or the Big Island after landing. The SFO-HNL mainline segment is a separate calculation, but knowing the inter-island sweet spot is available shapes how you build the full trip.

For the San Francisco to Honolulu leg itself, start your availability search with Air Canada Aeroplan and United MileagePlus. Hawaiian Airlines flies this route, and so does United, both operating within a framework where Aeroplan can price partner space competitively. Flying Blue is worth a check as well, particularly during its monthly Promo Rewards cycles, which have historically included transpacific routes to leisure destinations. Search all three programs before committing to a transfer, since award inventory varies significantly by carrier and date.

Economy saver space on SFO-HNL is more consistently available than premium cabin inventory, but "more available" is not the same as "always open." Summer travel, holiday weeks around Thanksgiving and Christmas, and spring break windows see compressed availability across every program. Hawaiian Airlines releases its own space through its HawaiianMiles program, and United controls its own metal separately. Checking both the operating carrier's own program and partner programs gives you the widest view. Build in flexibility of at least a few days on either side of your target dates, especially for travel between June and August.

On transfer paths, the Avios inter-island angle is reachable from three major bank currencies. Chase Ultimate Rewards transfers to British Airways Avios at 1:1, as does American Express Membership Rewards and Capital One Miles. All three move at 1:1 to Avios, so 5,000 bank points covers one inter-island segment at the 2.6¢ sweet spot. For the mainline SFO-HNL award, Aeroplan is reachable from Chase, Amex, and Capital One at 1:1 as well, making it a flexible target once you have confirmed space in hand.

Grounding the math against our conservative valuations matters here. Our 1.5¢ Avios valuation reflects realistic redemptions across the program's full range of uses. The inter-island redemption at 2.6¢ clears that benchmark by more than 70 percent, making it one of the stronger Avios uses in the domestic Hawaii context. For the SFO-HNL segment booked through Aeroplan, our 1.8¢ Aeroplan valuation is the benchmark; a redemption that prices out above that figure in cash value is worth pursuing, one that falls below it deserves a second look at whether paying cash or using a different currency makes more sense. Run the specific award price against the cash fare before transferring any points.

Find space first, then transfer.
