I think they should charge for a carry on bag (or free for elites) and then allow free checked bags. Along with more strict screening of bag sizes. Additionally, window to aisle, back to front would seem to be a much better way to do things. I don't understand why people think SKY or PREM is a benefit. Why do you want to sit in the front of the plane while everyone bumps into you as they make their way to the back.
