ATA is your best bet and the out riggers are a good choice but i would look into other options the outriggers in Maui can be a bit much. Not sure what your budget is and ATA just joined with southwest so they have opened flights to Maui everyday. I also have a car rental that you can rent a jeep for as cheap as 40.00 a day. This will make your must trip to Hana an even better trip (Maui Jeep Rentals 1-800-701-5337 ) Have fun you will love it.
