This is really not surprising nor outrageous. Some airlines already do this, including JetBlue and United, which offers more legroom in Economy Plus, a separate section in coach that has up to 5 extra inches of space. US Airways charges for window or aisle seats. Continental is simply monetizing that which its customers desire: more space. Think of the Kevin Smith/Southwest debacle. There is really no incentive for the airline industry to offer coach customers a baseline level seat that is too comfortable, when they know that we will pay more for every extra inch of comfort we can afford.
