Travelers have found it’s best to book a flight 48 days in advance to save up to 20% 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 48 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 Mexico City to Brazil 1-2 weeks in advance for as low as $1,011, or $1,016 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, August can be a great choice for travel to Brazil. Flights to Brazil from Mexico City in August are about $793 on average during August, but can be found for as low as $652.
