Honolulu-oahu
 

Does Anyone Know Of Any Helicopter Companies Based In Oahu For Booking Pleasure Flights Of Island. I Have A Cruise Booked In March And Visiting Island For Just One Day.

Thanks Eddie I shall make contact.

I know Mauna Loa and Ben Fouts and they're a flight training school. Their training helicopter is the Robinson R22 which takes one pilot and one passenger, although they may be able to get an R44 (one pilot and 3 pax). Just to give you a couple more choises:

Blue Hawaiian helicopters is the leading helicopter tour company. I have rode on their Eurocopter EC130 helicopter which is the state of the art touring helicopter (one pilot plus 6 pax). They have very experienced pilots and they make great tour guides.
Blue Hawaiian's Hawaii helicopter tours offer the best tours in Hawaii

Makani Kai Helicopters has a Eurocopter AS350 Squirrel helicopter which is a very reliable machine, an industry standard (one pilot plus 5 pax). Contact P.J. O’Reilley, the sales manager - I know this guy too and he'll make things happen for you.

I love Hawaii and I hope you'll enjoy it too.

Makani Kai lost an AS350 recently so might be easier to check with Blue Hawaiian first.
