Changing seats on Hawaiian Airlines is easy. You can do it online by logging into My Trips on their website. Once your booking appears, click “Change Seat” or “Seat Map” to choose a different seat from the available options. Depending on your fare type, you may need to pay for premium or preferred seats (like extra legroom or front-row seating). You can also select or change seats via the Hawaiian Airlines mobile app or at the airport kiosk. For upgrades to First Class, you can request them online or inquire at check-in if seats are open.
