When booking flights to South America, it’s good to know how to prepare for your flight. Many times, the flight leaves early in the morning so it might be worth it to book a hotel right at the airport. Before you book flights to South America, it’s a good practice to call credit card companies to let them know you will be out of the country, as you might have difficulty using your card while traveling around the country. Make certain your passports are valid, as well as driver’s licenses. When flying to South America, depending on what country you visit, you might need a tourist visa, so research the particulars before your trip. Also, some countries might require pre-approval for the visa, and other might let you pay at the border.
