The Hawaiian airlines checked baggage policy varies based on route and frequent flyer status. While international airlines may offer a complimentary checked bag, inter-island flights usually have more reasonable prices. Elite level holders and HawaiianMiles members are eligible for free or heavily discounted checked baggage. There are weight and size restrictions in the policy, and overweight or oversized luggage will incur additional costs. By being prepared for the Hawaiian Airlines checked luggage rules travelers may maximize their baggage allotment on every trip and prevent extra expenses.
