I would think about it, especially if you fly for a regional airline. I took a job in Colombia and I actually enjoy it. It is not Brazil, but had the apportunity to get into an A320 with low hours. I think Latin America is a good steping stone if you want to move into better jobs overseas. It's a shortcut to fly bigger equipment. Look at Brazil like an adventure, and maybe it would lead you to a better opportunity. Now, if you fly for a major, don't even think about it.
