Keeping in mind that there is no assurance of being able to secure award seats on your desired dates, AS currently offers nonstop service to HNL, KOA, and OGG (but not ITO) from both OAK and SJC. Although you can redeem AA, AS, or BA miles for travel on AS, for nonstops between the West Coast and Hawaii, BA offers the best redemption value: only 12,500 Avios for one way in Coach. If you needed to route via LAX on AA, BA would charge an extra 4,500 Avios for the flight between SFO/SJC and LAX. You can earn BA Avios directly with the Chase/BA Visa card, and indirectly with the Chase Sapphire Preferred Visa or MasterCard. (The Chase SP card earns "Ultimate Rewards" points, which can be converted to BA Avios on a 1:1 basis.) Check MilesBuzz! for current sign-up bonuses for these cards.

In the past, there was a Chase/BA Visa sign-up bonus of 100,000 BA miles with a $95 annual fee. I believe that the current offer is only 50,000 BA miles (now called "Avios"), but who knows if a more lucrative offer is in the offing?
