Island Air is making the switch exclusively to card transactions.
The small interisland carrier said Tuesday it now will no longer accept cash for booking flights and checking in bags so that it can ensure a more efficient check-in for passengers. Baggage is processed at the airport during check-in.
The major credit and debit cards accepted by Island Air include MasterCard, Visa, American Express, Japan Credit Bureau and Discover.
Island Air, which offers more than 250 weekly flights, offers nonstop service between Honolulu and the neighbor island airports of Kahului, Lihue and Lanai.
