This policy seems fair and reasonable.
But what astounds me, once again, is the vitriol in evidence against obese people.
I will say this only once, so please listen carefully.... I fit easily into a standard sized airline seat.
As it happens, I'm a pretty smart guy, educated to masters degree level and travel the world doing consulting work and running seminars.
I come across many people who do not try to make the most of their talent and some who are just born dim.
You could compare these people to obese people in the sense that some people don't try to improve themselves and some cannot.
Should we despise these people, too?
What is it with some of you people???
