Some refunds are likely for Air Hawaii tickets.

Jerry Smilowitz, a consumer law specialist in the California attorney general’s Los Angeles office, said a federal law enables consumers to obtain refunds for services that were paid for but not delivered. He said it was likely that those who purchased Air Hawaii tickets with credit cards could obtain full refunds. Air Hawaii has discontinued service and filed a bankruptcy petition last Friday. Smilowitz said ticket holders should write to the bank that issued the credit card and give all details regarding the airline and the tickets purchased.
