The US airlines still have hundreds - if not thousands - of qualified pilots on furlough, with plenty more waiting for their first hour-building job. So how is this guy proposing to set up working visas for the dreaded aliens?
If he is running an inter-island service, which larger airline is hosting his reservations system, and has it been paid for yet? Without an alliance and a reservation system, no commuter air service will survive more than the time it takes for the first fuel account arrive in the mail.
Unless you are planning a Hawaiian holiday anyway, save your money and leave this scam to the locals to sort out.
A fool and his money are soon parted.
