One of the best things I like about Hawaain Airlines is its mileage program lets you get miles for shopping at Amazon.com. If you have not signed up for their mileage program, you should do so. It is free, and it’s the only way currently to get miles for shopping at Amazon.com. Everytime I want to buy something on Amazon, I simply log into my Hawaiin Airlines emarket site and navigate to Amazon from there. You get 1 miles for every dollar spent at Amazon. Couple that with their cobranded credit card, and you will be on your way to Maui in no time! Have you used any of the shopping portals?
