Hmmmm can I have a rebate from the amazingly fat woman who sat next to me on a flight back from Austria once who was ooozing under the arm-rest and into my seat? I mean, she didn't even buy me dinner first!
OOoo fatism begins! WON'T SOMEONE THINK OF THE CHILDREN!
Let's be realistic. This isn't aimed at people carrying a few pounds they (or their partners) might wish they weren't. This is for the chronically obese people who genuinely don't fit into a normal aircraft seat. It's not just for them, it's for the people who have to sit next to them too.
It costs more to fly them, I don't want to have to pick up that extra tab, so they should pay. And before someone tells me that "It's genetics" or "I'm big boned" it's not. There are a few hormonal issues that might do it, but in the very vast (oh the pun) number of cases it's simply due to too many pies. And if it's medical, then I'm sure the airline would be accomodating (the puns keep coming!)
I'd probably better don my flame proof suit now...
