We are replacing all our Main Cabin seats on the majority of our fleet with a new design that offers additional living space, the same level of comfort and a slightly thinner seat back. With the thinner seat back and the reconfiguration of our galleys, we're able to add one row of seats to our 737-800s. The distance between seats remains unchanged with the new design that offers additional knee room by relocating the literature pocket above the tray table. The new seats will also feature 120-volt power plugs at every seat. Lastly and most directly related to your concern, with these changes all Main Cabin seats will offer a similar amount of space and we will not be charging more or less for any particular seat on the plane. -David
