Bom dia Ed
I think that Portuguese pilots have an advantage here, there seems to be some agreement between the countries for a fast-track scheme that reduces the time considerably, although I don't know the details. There are some whispers that Azul have some Portuguese candidates in the current recruiting round, but nothing that I can substantiate, so maybe its just a rumour.
I'm not really in favour of a completely closed market, but the reasons for opening things up concern me more. There is quite clearly no intention of recruiting well qualified crew from major carriers but simply a means to reduce cost by bringing in pilots from smaller countries who will fly here for even less than the present salaries. That is my opinion, not based on any stated fact, but from conversation with a number of well connected individuals in Brazilian aviation.
Boa sorte
