The middle of the year often prices better, as long as you stay clear of the school holidays. Six to ten weeks ahead is often enough to book, a shorter lead than Europe or Asia usually needs. Miami, Houston, Dallas, Atlanta and New York are the main US gateways south. ### The short version - **Expect full flights in the northern winter** and over the year-end holidays. - **Look at the middle of the year,** outside the school holidays, for better fares. - **Book six to ten weeks ahead,** and earlier for the holidays. - **Fly midweek** when you can, and price the return day as carefully as the departure. - **Start from a gateway south.** Miami, Houston, Dallas, Atlanta and New York are the main ones. ## Which months are busiest for business class to South America? The busiest stretch runs through the northern winter and the year-end holidays, so the December and New Year weeks are the ones to book early. The middle of the year often prices better, outside the school holidays. School calendars differ by country, so check the one for your destination before you fix your dates. ## How far ahead should you book business class to South America? Six to ten weeks ahead is often enough. That is a shorter window than our [Asia booking guide](https://buybusinessclass.com/blog/when-to-book-business-class-to-asia) gives for transpacific trips. For the year-end holidays, start before that window opens. As on other long-haul routes, booking ten or eleven months out rarely shows the lowest fare, because airlines often load sale fares later, and fares usually rise in the last two or three weeks before departure. Midweek departures, Tuesday or Wednesday in particular, often price below the weekend. ### A sample timeline Say you want two weeks in Buenos Aires in late August 2027. Start pricing in May, give your agent a range of dates rather than fixed ones, and book by mid-June, about ten weeks out. For a trip over the December holidays, move that whole timeline earlier. ## Which US cities and airlines fly to South America? Miami, Houston, Dallas, Atlanta and New York are the main gateways south, and within the region São Paulo, Santiago, Lima, Bogotá and Panama City connect most destinations. A one-stop trip through one of those hubs, on a single ticket, reaches cities without a flight from the US. - **[American Airlines](https://buybusinessclass.com/airlines/american-airlines)**, whose hubs include Miami, Dallas Fort Worth and New York JFK, flies Flagship Business to South America, with São Paulo and Buenos Aires among its popular destinations. - **Delta** flies Delta One from hubs such as Atlanta and New York JFK to South America, among other regions. - **United** flies Polaris from hubs such as Newark and Houston to South America, among other regions.
