When would I have to catch a flight from Oahu?

Tours down the road to Hana, pickup in the airport area in Kahului by about 7:30am. This means your flight from Oahu will be closer to 6:30am so you would need to be at the airport around 5:30am in Honolulu. You will be returned to the airport around 5:30pm 1. Road To Hana Maui Day Tour From Oahu
