NOTE: Since this post was originally written, US Airways no longer offers miles for shopping at Amazon. Also, Hawaiian airline miles have droppe to 1 mile per dollar.
Others have previously posted this, but I think this is worth a reminder. Both US Airways and Hawaiian Airlines have shopping portals that award miles for Amazon.com purchases that are initiated through their portal. US Airways gives 1 mile per dollar spent at Amazon, whereas Hawaiian Airlines offers 2 miles per dollar. These bonuses are over and above any miles earned from using a reward credit card for the purchases.
The Hawaiian Airlines deal has a few benefits worth noting beyond the double miles:
- Hawaiian Airlines miles can be used for booking award flights on other airlines: Delta, Continental, Virgin Atlantic, and Korean Air
- Hawaiian Airlines miles can be transferred from person to person for free if you have a Hawaiian Airlines credit card. This can be a huge benefit if you have multiple family members or friends with small account balances. Combine them together for an award flight!
- Hawaiian Airlines miles can be transferred to Hilton points: two Hilton points per mile! So, since you get two miles per dollar from shopping at Amazon.com, you will essentially get 4 Hilton points per dollar if you choose to use your miles this way.
So, before shopping at Amazon, remember to go through one of these portals to earn extra points!
