We flew on Go! two years ago and are using them again this year. We booked for $58 from HNL-LIH. Baggage fees were cheaper than Island Air and about the same as Hawaiian. The planes are small -- the ones from two years ago sat about 12-14, but we flew low enough to clearly see south Maui and Molokini as we flew to the Big Island. It was very enjoyable if you do not mind small planes.
