Travelers have found it’s best to book a flight 37 days in advance to save up to 3% 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 37 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 Las Vegas to Iceland 1-2 weeks in advance for as low as $784, or $787 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, July can be a great choice for travel to Iceland. Flights to Iceland from Las Vegas in July are about $753 on average during July, but can be found for as low as $591.
