I'm asking this question, because why a cabin is limited to the size 6, I'm ok for the luxury and first class because it's useless to have a bigger one, they want to be alone on their big cabins, but for the economic and business class, why it's limited to the size 6,b ecause actually on big planes, it's totally normal to have more than 32 passenger on the same cabin, so if we up the size to 7 and 8 we could transport 64 and 128 passengers in this cabins. And I don't see where is the problem to "store" 128 passengers on the same place. It's actually the case on big planes.
