Who loves free miles? I do. However, I do not have a Twitter account yet, nor a Hawaiian Airlines account, so I am not taking advantage of this offer. However, if you are members of both programs, you can receive 500 free Hawaiian Airlines miles just for linking the two accounts.
Registration can take place on the Hawaiian Airlines page. Simply enter in your Twitter name, Hawaiian Airlines mileage number, and email address to join your accounts and receive the 500 free miles.
