I am going to participate in a series of academic events this December in South America. (I myself am from Perú.) The first starts at December 4 in Santiago (Chile), then I'll be about ten days in Sao Paulo (Brazil), and then I'll be back in Chile for a week, in Concepción.
I plan to travel from Lima to Santiago, then to Sao Paulo, then to Concepción, and finally back to Lima.
I understand it's good policy to buy tickets as early as possible, but also waiting for special days with discounts. The problem is that Black Friday is perhaps too close to the first event date.
Is it too risky for me to wait until the fourth Friday of November to buy my plane tickets?
