I've found airfare from Austin, Tx to Honolulu including interisland travel to Big island and Kauai for $780 per person w/tax for June 2004. Is this a good price? or can I expect airfare to good down.

The best rates for non-westcoast travel to HNL (for April/May 2004) I have ever seen were recently listed in this post:

I'M THINKING W/INTERISLAND FARE FROM HONOLULU TO HILO, HILO TO KAUAI,
KAUAI BACK TO HONOLULU FOR FLIGHT HOME THE $780 SHOULD BE REASONABLE $500 OR SO FOR TEXAS TO HAWAII AND $200 + FOR INTERISLAND AND TAXES.

I think it sounds GREAT! Good job!!!

Instead of flying back to HNL and then to mainland for return home, can you get fare down by flying from Kauai back to TX? Sometimes airfare isn't much different flying into one island and returning from another. Did that with 2, not sure if it makes much diff with 3. Either way seems like what you found is pretty good.
