Dreaming of paradise without breaking the bank? Here’s how to book cheap flights to Hawaii. Start by being flexible with your travel dates—midweek departures and off-season months like February or September often offer the best deals. Use flight comparison tools like Google Flights or Skyscanner to track price drops and set alerts. Consider flying into less expensive airports like Honolulu (HNL) or Maui (OGG), and look for connecting flights from major U.S. hubs. Booking in advance—ideally 1 to 3 months ahead—can also save you money. With a bit of research and flexibility, Hawaii can be surprisingly affordable.
