Well, that sounds about right for budget airlines. I know when I took Wizzair (budget airline in Europe) they did most of these that you've outlined. They have a "club" price and a non club price, charge for bags, expect carry-on, charged for food, and if you want the seats in the front with a little extra leg room, they charge for that! But can't say that the prices were so bad... I mean usually budget flights are short, so you don't have to necessarily eat on the plane, which saves a bit of money, and if you can stand to be squished in a seat for 1-4 hours then you don't have to pay for that extra leg room ;)
