Re: Finding decent fare from Brazil to Atlanta.
It has been my experience, having lived overseas with a college student in the States, that student travel organizations have special student fares negotiated with the airlines that are available to students and faculty. For example, STA Travel in Austin, Texas has these fares available for students originating their travel in the U.S. only. Have the student contact a university in Brazil for information on a local travel agent offering fares to the U.S.. Usually these fares are valid for return travel up to a year from outbound travel.
