Guaranteed low interisland fares in Hawaii

(expires March 11)

There hasn't been a sale like this since the 3rd interisland carrier, Go Airlines, entered the market (and subsequently bankrupted Aloha Airlines).  Hawaii Airlines is offering a guaranteed fare of $43 per segment for interisland segments and some fares as low as $27 per segment.  This is especially useful because flights to Honolulu are usually cheaper than direct flights to neighbor islands.  You must register online using you HawaiianMiles frequent flier number by March 11 and book travel before May 15.
