as that is who we booked through and ended up with Alex Air for $140 each for a hour long flight. We used the same agent for a Safari Helo tour in Maui for the same price also for an hour tour. I know that you can also go directly to the websites of some of the helo operators and you can buy them directly from them but we found a better deal by going through this broker. You can also book thought the ship if that is your preferance but the prices are usually a good bit higher.
