The Hawaiian airlines baggage policy allows passengers to bring one carry-on bag and one personal item onboard, both subject to size restrictions.  Depending on the travel route, checked luggage fees might vary on inter-island and U.S. mainland flights, the first bag typically costs about $30, while the second bag costs about $40. Certain credit card holders and HawaiianMiles members may be eligible for discounts or fee exemptions. Because overweight and bulky bags attract additional fees, it is imperative to check the criteria beforehand. By being informed of Hawaiian Airlines baggage policies travelers can avoid unpleasant surprises at the airport.
