Call Hawaiian to check availability. If they have it, set up an FF account and then call Amex to transfer your points to HA miles. Takes about three business days.</font>
Is Amex partnered with AA or NWA? If so, getting the ticket through Hawaiian may not be the best option.
Hawaiian Airlines wants 10,000 miles for an interisland ticket, whereas AA and NWA only want 5,000 for the same Hawaiian Air ticket. You could save 50% of your points.
Although you will save 50% miles, there is more of a hassle factor using AA or NWA -- since these would be awards on partner airlines, you will have to get paper tickets sent to you through the mail.
Also, if you decide you want to change the dates of the flight after the ticket is sent to you, I think AA will (or shortly in the future start to) charge a change fee. With Hawaiian (and possibly with a NWA reward), this isn't the case.
