I reported earlier that go! was offering one way inter-island flights from $9 from June 1st through September 30th.  I just got an e-mail from go! indicating that this fare sale was very popular and many dates sold out within hours.  They have decided to expand the sale.  

Starting at 5pm Hawaii time tonight (Tuesday), we will make $9* seats available on select mid-week flights from October 1 thru December 15, 2007.  These fares will be valid for travel on select flights Tuesdays thru Thursdays with blackout dates around the Thanksgiving Holiday.  Tickets still must be purchased by Friday, June 1, 2007.  Hurry and visit our website to take advantage of these great deals before they sell out!
