Travelers have found it’s best to book a flight 28 days in advance to save up to 11% compared to booking the same week of travel. As your travel date approaches, the cost of this flight route may potentially increase. While opting to book 28 days out may not be an option for all, there are still additional ways to secure a deal in the near future. You might find a flight from Indiana to Hawaii 1-2 weeks in advance for as low as $546, or $555 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in June. For low rates, September can be a great choice for travel to Hawaii. Flights to Hawaii from Indiana in September are about $544 on average during September, but can be found for as low as $355.
