"The seat is a revenue generator," [seat manufacturer's vice president Jeff] Luedeke says. "Normally if you look at a 737 or A320 there are three seats on each side. If you wanted maximum comfort you could do two on each side -- and make the seats a lot wider. But with the reduced head count the operational costs don't work out."Apparently air passengers are willing to pay for faster travelling speeds rather than passenger comfort, given their willingness to put up with passenger loading practices that violate livestock handling standards, and a preference for bargain fares never mind how narrow the seats are.

Transportation companies have to worry about farebox yield.
