It s reserved only for the real road warrior, which I am not. Half the time it seems like the first class seats are reserved for airline personnel anyway. Now, also, I realize my size makes some people uncomfortable, but there are things that make me uncomfortable too. Unfortunately, the problem with flying today is the insistence of the airlines to pack in as many seats as possible. Flying has become commonplace, but somehow we need to at least make it comfortable.
Statistics prove that more people are taller and heavier than any previous time.
The airlines need to acknowledge this. Or at least designate something to identify larger passengers and give them some reasonable assurance of a comfortable ride. I am not going to stop traveling because the person next to me is uncomfortable. Delta gave a voucher to those who agreed to be bumped to another flight that would put them at destination only a hour later. They accepted this agreement.
