How do air lines work? I see a lot of fat people hate on air planes, but I'm wondering how airlines handle obese people exactly? What if a hammy (think of my 600lb life) can not physically fit in a seat and the rest of the plane is full, does the airline say sorry, but you have to reschedule and buy two or three seats. What happens if they try to bring their scooty puffs on the airplane does the airline strap them in like they do on buses. Does someone have to request a seat belt extender prior to getting on the plan and if they do doesn't the airline kinda know they are getting a two ton tessy that needs to buy two or more seats; will they tell the person they need to buy more than one seat? And what happens on a full plane where you have multiple fatties (probably going to an NAAFA conference) and they take up more than one seat and they only purchased one. Do you let the thin people all sit comfortably and tell the fatties to reschedule and buy more than one plane ticket? What happened when a normal sized person gets seated next to a hamplanet ditto monster whose fat just kinda engulfs their seat taking up more of the seat than they are?   Do airline generally ask for your weight and height, are they allowed to?
