I’ve done a post previously for Passaredo, it’d be a great one to see because not only would it supply the Embraer 120 for GRU but also the E145/E135 which for a Brazilian aircraft, they’re all really lacking down there with operators. The only other EMB 120 and E145 operator I could find was Rio Sul but that ceased in July 2006 and merged with parent Varig disposing of its E145s and EMB 120s so is before the devs 2010 livery date.
Denver Air Connection has a dapper livery, would love to see it in-game.
