The seats are also too small, at least for Western men (and increasingly for women too). I am quite tall and find flying an experience to be endured by gritting my teeth, but for taller and heavier people it is almost torture. I recently saw a man with half his leg in the aisle, taking up almost all the walking space. If you are unlucky enough to sit next to a very large man, a fairly common sight especially in the US, the entire flight becomes a series of small and large movements, squirming and twisting. However, people want to pay less and less, while airlines earn more and more. Competition is limited and I don't see how flight comfort can improve for the average passenger.
