In many forums and blogs about air travel in Brazil the "Brazil Air Pass" (or sometimes a "South American Airpass") is mentioned. With this airpass, you can take multiple flights with the same airline inside Brazil, usually for a cheaper prize than when booking the flights individually.
However, I am not able to find this airpass on the websites of the airlines mentioned in the blogs. Do these airpasses still exist, or where they abolished?
Edit based on comment: The only thing I am able to do on some websites is fill in a form to "get contacted with more details". When buying plane tickets (or anything else on the internet) I never had to do something like this. Normally, I enter my information and press "buy" at the end to buy it directly. Is this normal for the Brazil Air Pass that you have to do it with these kind of forms where you cannot buy it but only indicate your interest?
