Using http://www.bookingbuddy.com/, and then sidestep, the cheapest flights I found were $737, which seems high to me, but I don't know how much it normally costs to fly to Hawaii. http://www.sidestep.com/s/flights.jsp?searchid=D0uiO7xRbI93Q6hqaky0gg&completed=true The cheapest on Travelocity is on US Airways for $699 http://travel.travelocity.com/flights/AirSearch.do?SEQ=12188156075097152008 The cheapest on Expedia is $736 on US Airways http://www.expedia.com/pub/agent.dll?qscr=fexp&flag=q&city1=honolulu%2C+hi&citd1=raleigh%2C+nc&date1=8/18/2008&time1=362&cAdu=1&cSen=&cChi=&cInf=&infs=2&tktt=&trpt=1&ecrc=&eccn=&qryt=8&load=1&airp1=&dair1=&rdct=1&rfrr=-429 On the US Airways site, they have a flight for $699 also http://www.usairways.com/awa/booking/BuildItinerary.aspx
