My only opinion on the Embraer is Cabin comfort and I must say, they are very comfortable!
I love the very spacious cabin and how light it is. A big plus for me is the extra large windows. Usually whenever I fly I'll take the E90 as it is my favorite plane. Only downside is no Oven for food in J. That's the only reason why I've decided to take the A319 to Montreal in a few weeks. I want a hot meal.
