**Hawaiian Airlines Check-In**
Hawaiian Airlines offers online check-in starting 24 hours before departure and up to 1 hour before most international flights. Passengers can check in via Iberia's website or mobile app, which provides an electronic boarding pass. At the airport, passengers can also use self-service kiosks or traditional counters to check in, particularly if they have luggage to drop off. It's important to arrive early for check-in and security screening, especially for international flights.
