When flying from St. Louis to Argentina, the time of day you decide to fly out makes little to no difference towards the overall price you’ll pay on tickets.
Travelers have found it’s best to book a flight 39 days in advance to save up to 39% 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 39 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 St. Louis to Argentina 1-2 weeks in advance for as low as $1,390, or $1,610 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in August. For low rates, July can be a great choice for travel to Argentina. Flights to Argentina from St. Louis in July are about $1,200 on average during July, but can be found for as low as $934.
