why should an obese person pay for one fare and take up two seats. what's so fair about that. also this is just one example. my daughter made a trip home from la, she is 4'10 and weighs less than 90 lbs, she set next to an obese woman who took up part of her seat. my daughter could not find her seat belt and was to embarrassed to ask the woman to move to get it, so she flew from la to memphis without her seatbelt and said she was about to cry she was so uncomforable. fat people should either buy first class or buy according to how wide they are. maybe we shoud have seats at the airlines so they have to sit in it before boarding, don't fit, then upgrade, buy two seats or go home and rebook. their is no excuse for anyone thinking it is ok to be shoved out of your seat by anyone.
