Demand Delta airlines to improve overweight passenger policies

Not only is guaranteeing a safe flight a part of president Bastian jobs, but also guaranteeing the delta airlines passengers are comfortable beyond reasonable doubt. The overweight policy that is currently available is not appropriate. I believe all overweight passengers should be required to purchase an extra seat to insure that all passengers have the appropriate amount of space to travel comfortably. What good is a long flight if you can't fly comfortablely.
