The Internet is your best choice to find cheap airfare to Hawaii.  The net includes numerous websites that give you the latest updates on airfare prices.  All you have to do is click the mouse a few times and you will know the latest prices.

One way to get your ticket is directly from major airline websites.  Most of these airlines will have special deals on Hawaii flight from time to time.  Certain days will have better deals than other days.  Be sure to check the airline websites between two or three times a day so that you do not miss these great deals.  They will sell quickly once they are announced.

There are three major travel websites that can make the search for cheap airfare much easier.  Orbitz, Expedia, and Travelocity all have deals with airlines to give special prices to consumers.  The prices will most likely vary on each website.  Make sure you check each of the websites and find which one suits you best. 

Another great group of websites are those that use search engines to automatically search all the travel agencies are airline websites for you.  They will display and compare all the cheapest fares from every website.  This is about as easy as it gets.
 
Last but not least is Priceline.com, which uses a more unique method of interacting with the consumers.  As the consumer, all you have to do is enter the price that you are willing to pay for the ticket.  They will do the rest, including calling and searching everywhere to find a ticket at the price you quoted.  The only downfall to this method is the ticket is always non-refundable.  Make sure you pick the right date and that there will be no changes.
