Travelers have found it’s best to book a flight 17 days in advance to save up to 8% 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 17 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 Grand Rapids to Argentina 1-2 weeks in advance for as low as $955, or $1,073 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 Argentina. Flights to Argentina from Grand Rapids in July are about $933 on average during July, but can be found for as low as $558.
