Island Air announced it will stop flying to Molokai after April 1, and will contact customers with later reservations to transfer them to other carriers or refund their money. No reason was given, but the announcement comes after Hawaiian Airlines said it would offer several daily roundtrips to Molokai on its Ohana turboprop division.  Island Air makes two runs a day to Molokai, but it makes five daily roundtrips to Lanai.  Larry Ellison, who owns most of Lanai, bought Island Air last year.
