Andrew;
I actually wasn't directing any comments at you, and I'm sorry you have health problems.
But why should I pay for people's consumer needs? I already pay taxes for health care, I shouldn't be forced to subsidise non-urgent travel.
I didn't say you shouldn't travel - travel all you want! But SOMEONE has to pay, and if its not you, its the rest of the passengers.
Next time I have excess baggage will YOU pay for it?
