Who is going to pay for airlines providing extra wide seats? Well certainly not the skinny people, in fact they probably should get a discount for taking up less space. This whole argument wreaks of fat people being unworthy and an inconvenience to others and it just further stigmatises *fatties* IMO.
Having to pay for a whole extra seat is really unfair because it essentially doubles travel costs for people who happen to fall outside of an arbitrary size range set down by airlines. So essentially it sends the message that if you must be fat, you could at least have the decency to be wealthy (but we all know that to be impossible because you are clearly uneducated because you must be making poor food choices that make you fat in the first place, so just stay home) Imagine how you would feel if you could not afford to travel to a funeral for example because you couldn't afford to pay for your left saddlebag?
Sorry, I have a bit of a chip on my shoulder about this, so I can only imagine how someone who doesn't fit a plane seat must feel.
