To change a flight on Hawaiian Airlines, visit hawaiianairlines.com and select “My Trips.” Enter your confirmation code and last name to find your reservation. Click “Change Flight” to choose a new schedule. Hawaiian Airlines has removed most change fees for Main Cabin and First Class fares, but Saver fares are non-changeable. You’ll need to pay the fare difference if the new flight costs more. If you booked through a travel site, changes must be made via that platform. You’ll receive a new confirmation once the change is complete. For help, call Hawaiian Airlines support.
