The last time I brought my wife's cats only one airline was permitting them in the hold and it was 500 each . I believe a large crate for a dog was 1500. It was Aerolineas Argentina and that was a 16 months ago. There are specific requirements for pets that you should research on Argentine websites including all the certificates and time frames from obtaining said certificates and the flight. I believe that was 10 day window. Sorry a little foggy on all the details but be prepared to spend some cash. Also speaking from experience leave an escape plan I have been coming here for almost 20 years and can only stand it for 6 months at a time it's not for everybody.
