Embraer is a Brazilian aircraft manufacturer that has specialised in producing primarily regional and small sized narrow body planes. Its most successful aircraft families are the E-175 and E-195. A second generation has also been produced but it unfortunately didn't have as much success, particularly the E-195, due to a miscalculation by the producer. The largest market for Embraer jets is without a doubt the United States, where all major airlines use some variant of these jets in their regional fleets.
