So many people are blaming airlines for having smaller seats. They should make seats bigger for everyone, blah blah blah. They have bigger seats, it's called business or first class. It's like these people failed basic economics. If airlines had bigger seats in economy, they would carry less passengers. So they would have to charge more. Do you want to pay more for air travel? Probably not. The law of economics has dictated seat size, not your feelings. An airline can offer bigger seats and higher fares, but will likely not survive in the marketplace cause people usually choose the cheapest seat every time.
