Airlines now have big seats in airplane because people want feel comfortable and in the back of the seat have tablets to service food, but some people want to have smaller seats to have lower ticket prices. In mine opinion it is true if in-flight we have smaller seats, I will pay lower price than before. In the other hand the airlines should have big seat to make more money, and people pay extra for food or water. Now I agree to have small seats, and pay lower ticket price because if I want to travel in a exotic place or somewhere else I can afford it.
