that I pay for a full airline seat and only get to use 1/2 to 2/3 because someone is spilling over into my seat. Why should I upgrade to first or business class and pay extra? I'm not using more space than I paid for.

I have an obsese ex-coworker. He completely understands why he has to purchase two seats when he travels in fact, it makes him more comfortable as he has more space and he knows he's not inconveniencing someone. The company will pay for one and he pays for the other. To try and avoid paying, he trys to travel off peak where there is a better chance of the plane not being full.

Let me also show you another point of view. I'm disabled, I've had 7 operations on my legs. Because of that I have a ton of scar tissue on my legs. Flying with someone pressed up against my scar tissue is very, very painful. That's also not fair.

United is not the only airline to do this. The article I read said 30 other airlines already have this policy, Delta and Southwest are among them.

Please don't get me wrong, I have sympathy but not at my expense.
